Context 1: Passage 1:
Stones into Schools
Stones into Schools: Promoting Peace with Books, Not Bombs, in Afghanistan and Pakistan is a New York Times bestselling book by Greg Mortenson published by Viking in 2009   The book is the sequel to the bestselling book Three Cups of Tea and tells the story of Mortenson's humanitarian efforts to build schools in Pakistan and Afghanistan with his non-profit charity organization, Central Asia Institute (CAI)   CAI reports that as of 2010, it has overseen the building over 171 schools in the two countries  These schools reportedly provide education to over 64,000 children, including 54,000 girls, where few education opportunities existed before in the remote regions of Pakistan and Afghanistan 

Summary
Stones into Schools picks up where Three Cups of Tea left off in late 2003   Tracing the efforts of CAI to work in the northeast corner of Afghanistan, the book describes how the book's author and Sarfraz Khan worked to establish the first schools in the area   Mortenson and Khan's efforts were thwarted for a time when a devastating earthquake hit the Azad Kashmir region of Pakistan   CAI assisted with relief efforts in the region by setting up temporary tent schools and later build several earthquake-proof schools   After CAI's relief efforts were completed, the non-profit charity organization then opens schools in areas controlled by the Taliban and Mortenson assists the US military to formulate strategic plans in the region 

Advice solicited by US Military in Afghanistan
Due to attention paid to Mortenson's books first by their wives,  US military leaders in Afghanistan have sought Mortenson's advice on how to work with the elders of local Afghan communities since 2007   Seeking his knowledge on dealing with Afghan elders, the military has also included Mortenson as an active participant in meetings between the elders and US military commanders   He has not, however, accepted any payment for his services, nor does he have any contractual or other formal relationship with the US military 

Criticism
Allegations
On the April 17, 2011 broadcast of CBS News' 60 Minutes, correspondent Steve Kroft alleged inaccuracies in Stones into Schools and its prequel, Three Cups of Tea   In particular, CBS News disputed  Mortenson's claim that he got lost near K2 and ended up in Korphe; that he was captured by the Taliban in 1996; whether the number of schools built and supported by CAI is accurate; and the propriety in the use of CAI funds for Mortenson's book tours  60 Minutes asked Mortenson for an interview prior to their broadcast, but Mortenson did not respond to their requests Jon Krakauer, a former financial supporter of CAI, has also questioned Mortenson's accounts separately and was interviewed for the 60 Minutes segment  The day after the broadcast, Krakauer released his allegations in a lengthy online article, Three Cups of Deceit - How Greg Mortenson, Humanitarian Hero, Lost His Way Mansur Khan Mahsudhe, a tribesmen Greg Mortenson describes as a kidnapper in Stones into Schools, states he is "looking into how to sue" Greg Mortenson for what he claims are lies about him 

Response to allegations
In response to the allegations made against him and his books, Mortenson wrote a statement that was published in the Bozeman Chronicle: "I stand by the information conveyed in my book, and by the value of CAI's work in empowering local communities to build and operate schools that have educated more than 60,000 students " Mortenson further stated, "The time about our final days on K2 and ongoing journey to Korphe village and Skardu is a compressed version of events that took place in the fall of 1993   "Scott Darsney, a respected mountaineer and friend of Greg Mortenson, wrote an email subsequently turned into an exclusive article for Outside magazine's online version as a response to the allegations against Mortenson  Darnsey questioned the accuracy and fairness of both the Krakauer piece and the 60 Minutes report  Darnsey had been interviewed by Krakauer, and maintained that Krakauer either misquoted or misunderstood what he said 
As a response to Krakauer's allegations, CAI produced a comprehensive list of projects completed over a period of years and projects CAI is currently working on  The list was released in December, 2011 (see external links below) 
Passage 2:
Socrates
Socrates (; Greek: Σωκράτης; c  470–399 BC) was a Greek philosopher from Athens who is credited as the founder of Western philosophy and among the first moral philosophers of the ethical tradition of thought  An enigmatic figure, Socrates authored no texts and is known mainly through the posthumous accounts of classical writers, particularly his students Plato and Xenophon  These accounts are written as dialogues, in which Socrates and his interlocutors examine a subject in the style of question and answer; they gave rise to the Socratic dialogue literary genre  Contradictory accounts of Socrates make a reconstruction of his philosophy nearly impossible, a situation known as the Socratic problem  Socrates was a polarizing figure in Athenian society  In 399 BC, he was accused of impiety and corrupting the youth  After a trial that lasted a day, he was sentenced to death  He spent his last day in prison, refusing offers to help him escape 
Plato's dialogues are among the most comprehensive accounts of Socrates to survive from antiquity  They demonstrate the Socratic approach to areas of philosophy including epistemology and ethics  The Platonic Socrates lends his name to the concept of the Socratic method, and also to Socratic irony  The Socratic method of questioning, or elenchus, takes shape in dialogue using short questions and answers, epitomized by those Platonic texts in which Socrates and his interlocutors examine various aspects of an issue or an abstract meaning, usually relating to one of the virtues, and find themselves at an impasse, completely unable to define what they thought they understood  Socrates is known for proclaiming his total ignorance; he used to say that the only thing he was aware of was his ignorance, seeking to imply that the realization of our ignorance is the first step in philosophizing 
Socrates exerted a strong influence on philosophers in later antiquity and has continued to do so in the modern era  He was studied by medieval and Islamic scholars and played an important role in the thought of the Italian Renaissance, particularly within the humanist movement  Interest in him continued unabated, as reflected in the works of Søren Kierkegaard and Friedrich Nietzsche  Depictions of Socrates in art, literature, and popular culture have made him a widely known figure in the Western philosophical tradition 

Sources and the Socratic problem
Socrates did not document his teachings  All that is known about him comes from the accounts of others: mainly the philosopher Plato and the historian Xenophon, who were both his pupils; the Athenian comic dramatist Aristophanes (Socrates's contemporary); and Plato's pupil Aristotle, who was born after Socrates's death  The often contradictory stories from these ancient accounts only serve to complicate scholars' ability to reconstruct Socrates's true thoughts reliably, a predicament known as the Socratic problem  The works of Plato, Xenophon, and other authors who use the character of Socrates as an investigative tool, are written in the form of a dialogue between Socrates and his interlocutors and provide the main source of information on Socrates's life and thought  Socratic dialogues (logos sokratikos) was a term coined by Aristotle to describe this newly formed literary genre  While the exact dates of their composition are unknown, some were probably written after Socrates's death  As Aristotle first noted, the extent to which the dialogues portray Socrates authentically is a matter of some debate 

Plato and Xenophon
An honest man, Xenophon was no trained philosopher  He could neither fully conceptualize nor articulate Socrates's arguments  He admired Socrates for his intelligence, patriotism, and courage on the battlefield  He discusses Socrates in four works: the Memorabilia, the Oeconomicus, the Symposium, and the Apology of Socrates  He also mentions a story featuring Socrates in his Anabasis  Oeconomicus recounts a discussion on practical agricultural issues  Like Plato's Apology, Xenophon's Apologia describes the trial of Socrates, but the works diverge substantially and, according to W  K  C  Guthrie, Xenophon's account portrays a Socrates of "intolerable smugness and complacency"  Symposium is a dialogue of Socrates with other prominent Athenians during an after-dinner discussion, but is quite different from Plato's Symposium: there is no overlap in the guest list  In Memorabilia, he defends Socrates from the accusations of corrupting the youth and being against the gods; essentially, it is a collection of various stories gathered together to construct a new apology for Socrates Plato's representation of Socrates is not straightforward  Plato was a pupil of Socrates and outlived him by five decades  How trustworthy Plato is in representing the attributes of Socrates is a matter of debate; the view that he did not represent views other than Socrates's own is not shared by many contemporary scholars  A driver of this doubt is the inconsistency of the character of Socrates that he presents  One common explanation of this inconsistency is that Plato initially tried to accurately represent the historical Socrates, while later in his writings he was happy to insert his own views into Socrates's words  Under this understanding, there is a distinction between the Socratic Socrates of Plato's earlier works and the Platonic Socrates of Plato's later writings, although the boundary between the two seems blurred Xenophon's and Plato's accounts differ in their presentations of Socrates as a person  Xenophon's Socrates is duller, less humorous and less ironic than Plato's  Xenophon's Socrates also lacks the philosophical features of Plato's Socrates—ignorance, the Socratic method or elenchus—and thinks enkrateia (self-control) is of pivotal importance, which is not the case with Plato's Socrates  Generally, logoi Sokratikoi cannot help us to reconstruct the historical Socrates even in cases where their narratives overlap, as authors may have influenced each other's accounts 

Aristophanes and other sources
Writers of Athenian comedy, including Aristophanes, also commented on Socrates  Aristophanes's most important comedy with respect to Socrates is The Clouds, in which Socrates is a central character  In this drama, Aristophanes presents a caricature of Socrates that leans towards sophism, ridiculing Socrates as an absurd atheist  Socrates in Clouds is interested in natural philosophy, which conforms to Plato's depiction of him in Phaedo  What is certain is that by the age of 45, Socrates had already captured the interest of Athenians as a philosopher  It is not clear whether Aristophanes's work is useful in reconstructing the historical Socrates Other ancient authors who wrote about Socrates were Aeschines of Sphettus, Antisthenes, Aristippus, Bryson, Cebes, Crito, Euclid of Megara, Phaedo and Aristotle, all of whom wrote after Socrates's death  Aristotle was not a contemporary of Socrates; he studied under Plato at the latter's Academy for twenty years  Aristotle treats Socrates without the bias of Xenophon and Plato, who had an emotional tie with Socrates, and he scrutinizes Socrates's doctrines as a philosopher  Aristotle was familiar with the various written and unwritten stories of Socrates  His role in understanding Socrates is limited  He does not write extensively on Socrates; and, when he does, he is mainly preoccupied with the early dialogues of Plato  There are also general doubts on his reliability on the history of philosophy  Still, his testimony is vital in understanding Socrates 

The Socratic problem
In a seminal work titled "The Worth of Socrates as a Philosopher" (1818), the philosopher Friedrich Schleiermacher attacked Xenophon's accounts; his attack was widely accepted and gave rise to the Socratic problem  Schleiermacher criticized Xenophon for his naïve representation of Socrates  Xenophon was a soldier, argued Schleiermacher, and was therefore not well placed to articulate Socratic ideas  Furthermore, Xenophon was biased in his depiction of his former friend and teacher: he believed Socrates was treated unfairly by Athens, and sought to prove his point of view rather than to provide an impartial account  The result, said Schleiermacher, was that Xenophon portrayed Socrates as an uninspiring philosopher  By the early 20th century, Xenophon's account was largely rejected The philosopher Karl Joel, basing his arguments on Aristotle's interpretation of logos sokratikos, suggested that the Socratic dialogues are mostly fictional: according to Joel, the dialogues' authors were just mimicking some Socratic traits of dialogue  In the mid-20th century, philosophers such as Olof Gigon and Eugène Dupréel, based on Joel's arguments, proposed that the study of Socrates should focus on the various versions of his character and beliefs rather than aiming to reconstruct a historical Socrates  Later, ancient philosophy scholar Gregory Vlastos suggested that the early Socratic dialogues of Plato were more compatible with other evidence for a historical Socrates than his later writings, an argument that is based on inconsistencies in Plato's own evolving depiction of Socrates  Vlastos totally disregarded Xenophon's account except when it agreed with Plato's  More recently, Charles H  Kahn has reinforced the skeptical stance on the unsolvable Socratic problem, suggesting that only Plato's Apology has any historical significance 

Biography
Socrates was born in 470 or 469 BC to Sophroniscus and Phaenarete, a stoneworker and a midwife, respectively, in the Athenian deme of Alopece; therefore, he was an Athenian citizen, having been born to relatively affluent Athenians  He lived close to his father's relatives and inherited, as was customary, part of his father's estate, securing a life reasonably free of financial concerns  His education followed the laws and customs of Athens  He learned the basic skills of reading and writing and, like most wealthy Athenians, received extra lessons in various other fields such as gymnastics, poetry and music  He was married twice (which came first is not clear): his marriage to Xanthippe took place when Socrates was in his fifties, and another marriage was with a daughter of Aristides, an Athenian statesman  He had three sons with Xanthippe  Socrates fulfilled his military service during the Peloponnesian War and distinguished himself in three campaigns, according to Plato Another incident that reflects Socrates's respect for the law is the arrest of Leon the Salaminian  As Plato describes in his Apology, Socrates and four others were summoned to the Tholos and told by representatives of the Thirty Tyrants (which began ruling in 404 BC) to arrest Leon for execution  Again Socrates was the sole abstainer, choosing to risk the tyrants' wrath and retribution rather than to participate in what he considered to be a crime Socrates attracted great interest from the Athenian public and especially the Athenian youth  He was notoriously ugly, having a flat turned-up nose, bulging eyes and a large belly; his friends joked about his appearance  Socrates was indifferent to material pleasures, including his own appearance and personal comfort  He neglected personal hygiene, bathed rarely, walked barefoot, and owned only one ragged coat  He moderated his eating, drinking, and sex, although he did not practice full abstention  Although Socrates was attracted to youth, as was common and accepted in ancient Greece, he resisted his passion for young men because, as Plato describes, he was more interested in educating their souls  Socrates did not seek sex from his disciples, as was often the case between older and younger men in Athens  Politically, he did not take sides in the rivalry between the democrats and the oligarchs in Athens; he criticized both  The character of Socrates as exhibited in Apology, Crito, Phaedo and Symposium concurs with other sources to an extent that gives confidence in Plato's depiction of Socrates in these works as being representative of the real Socrates Socrates died in Athens in 399 BC after a trial for impiety and the corruption of the young that lasted for only a day  He spent his last day in prison among friends and followers who offered him a route to escape, which he refused  He died the next morning, in accordance with his sentence, after drinking poison hemlock  He had never left Athens, except during the military campaigns which he had participated in 

Trial of Socrates
In 399 BC, Socrates went on trial for corrupting the minds of the youth of Athens, and for impiety  Socrates defended himself unsuccessfully  He was found guilty by a majority vote cast by a jury of hundreds of male Athenian citizens and, according to the custom, proposed his own penalty: that he should be given free food and housing by the state, for the services he rendered to the city  In the alternative, he proposed that he be fined one mina of silver (according to him, all he had)  The jurors declined his offer and ordered the death penalty  The official charges were: (1) corrupting youth; (2) worshipping false gods; and (3) not worshipping the state religion Socrates was charged in a politically tense climate  In 404 BC, the Athenians had been crushed by Spartans at the decisive naval Battle of Aegospotami, and subsequently, the Spartans laid siege to Athens  They replaced the democratic government with a new, pro-oligarchic government, named the Thirty Tyrants  Because of their tyrannical measures, some Athenians organized to overthrow the Tyrants—and, indeed, they managed to do so briefly—until a Spartan request for aid from the Thirty arrived and a compromise was sought  When the Spartans left again, however, democrats seized the opportunity to kill the oligarchs and reclaim the government of Athens The accusations against Socrates were initiated by a poet, Meletus, who asked for the death penalty in accordance with the charge of asebeia  Other accusers were Anytus and Lycon  After a month or two, in late spring or early summer, the trial started and likely went on for most of one day  There were two main sources for the religion-based accusations  First, Socrates had rejected the anthropomorphism of traditional Greek religion by denying that the gods did bad things like humans do  Second, he seemed to believe in a daimonion—an inner voice with, as his accusers suggested, divine origin Plato's Apology starts with Socrates answering the various rumours against him that have given rise to the indictment  First, Socrates defends himself against the rumour that he is an atheist naturalist philosopher, as portrayed in Aristophanes's The Clouds; or a sophist  Against the allegations of corrupting the youth, Socrates answers that he has never corrupted anyone intentionally, since corrupting someone would carry the risk of being corrupted back in return, and that would be illogical, since corruption is undesirable  On the second charge, Socrates asks for clarification  Meletus responds by repeating the accusation that Socrates is an atheist  Socrates notes the contradiction between atheism and worshipping false gods  He then claims that he is "God's gift" to the Athenians, since his activities ultimately benefit Athens; thus, in condemning him to death, Athens itself will be the greatest loser  After that, he says that even though no human can reach wisdom, seeking it is the best thing someone can do, implying money and prestige are not as precious as commonly thought 

Socrates was given the chance to offer alternative punishments for himself after being found guilty  He could have requested permission to flee Athens and live in exile, but he did not do so  Instead, according to Plato, he requested that a fine should be imposed on him and also suggested that free meals should be provided for him daily in recognition of his worth to Athens  According to Xenophon, however, Socrates made no proposals  The jurors favoured the death penalty by making him drink a cup of hemlock (a poisonous liquid)  In return, Socrates warned jurors and Athenians that criticism of them by his many disciples was inescapable, unless they became good men  After a delay caused by Athenian religious ceremonies, Socrates spent his last day in prison  His friends visited him and offered him an opportunity to escape, which he declined The question of what motivated Athenians to convict Socrates remains controversial among scholars  There are two theories  The first is that Socrates was convicted on religious grounds; the second, that he was accused and convicted for political reasons  Another, more recent, interpretation synthesizes the religious and political theories, arguing that religion and state were not separate in ancient Athens The argument for religious persecution is supported by the fact that Plato's and Xenophon's accounts of the trial mostly focus on the charges of impiety  In those accounts, Socrates is portrayed as making no effort to dispute the fact that he did not believe in the Athenian gods  Against this argument stands the fact that many skeptics and atheist philosophers during this time were not prosecuted  According to the argument for political persecution, Socrates was targeted because he was perceived as a threat to democracy  It was true that Socrates did not stand for democracy during the reign of the Thirty Tyrants and that most of his pupils were against the democrats  The case for it being a political persecution is usually challenged by the existence of an amnesty that was granted to Athenian citizens in 403 BC to prevent escalation to civil war after the fall of the Thirty  However, as the text from Socrates's trial and other texts reveal, the accusers could have fuelled their rhetoric using events prior to 403 BC 

Philosophy
Socratic method
A fundamental characteristic of Plato's Socrates is the Socratic method, or the method of refutation (elenchus)  It is most prominent in the early works of Plato, such as Apology, Crito, Gorgias, Republic I, and others  The typical elenchus proceeds as follows  Socrates initiates a discussion about a topic with a known expert on the subject, usually in the company of some young men and boys, and by dialogue proves the expert's beliefs and arguments to be contradictory  Socrates initiates the dialogue by asking his interlocutor for a definition of the subject  As he asks more questions, the interlocutor's answers eventually contradict the first definition  The conclusion is that the expert did not really know the definition in the first place  The interlocutor may come up with a different definition  That new definition, in turn, comes under the scrutiny of Socratic questioning  With each round of question and answer, Socrates and his interlocutor hope to approach the truth  More often, they continue to reveal their ignorance  Since the interlocutors' definitions most commonly represent the mainstream opinion on a matter, the discussion places doubt on the common opinion Socrates also tests his own opinions through the Socratic method  Thus Socrates does not teach a fixed philosophical doctrine  Rather, he acknowledges his own ignorance while searching for truth with his pupils and interlocutors Scholars have questioned the validity and the exact nature of the Socratic method, or indeed if there even was a Socratic method  In 1982, the scholar of ancient philosophy Gregory Vlastos claimed that the Socratic method could not be used to establish the truth or falsehood of a proposition  Rather, Vlastos argued, it was a way to show that an interlocutor's beliefs were inconsistent  There have been two main lines of thought regarding this view, depending on whether it is accepted that Socrates is seeking to prove a claim wrong  According to the first line of thought, known as the constructivist approach, Socrates indeed seeks to refute a claim by this method, and the method helps in reaching affirmative statements  The non-constructivist approach holds that Socrates merely wants to establish the inconsistency between the premises and conclusion of the initial argument 

Socratic priority of definition
Socrates starts his discussions by prioritizing the search for definitions  In most cases, Socrates initiates his discourse with an expert on a subject by seeking a definition—by asking, for example, what virtue, goodness, justice, or courage is  To establish a definition, Socrates first gathers clear examples of a virtue and then seeks to establish what they had in common  According to Guthrie, Socrates lived in an era when sophists had challenged the meaning of various virtues, questioning their substance; Socrates's quest for a definition was an attempt to clear the atmosphere from their radical skepticism Some scholars have argued that Socrates does not endorse the priority of definition as a principle, because they have identified cases where he does not do so  Some have argued that this priority of definition comes from Plato rather than Socrates  Philosopher Peter Geach, accepting that Socrates endorses the priority of definition, finds the technique fallacious  Αccording to Geach, one may know a proposition even if one cannot define the terms in which the proposition is stated 

Socratic ignorance
Plato's Socrates often claims that he is aware of his own lack of knowledge, especially when discussing ethical concepts such as arete (i e , goodness, courage) since he does not know the nature of such concepts  For example, during his trial, with his life at stake, Socrates says: "I thought Evenus a happy man, if he really possesses this art (technē), and teaches for so moderate a fee  Certainly I would pride and preen myself if I knew (epistamai) these things, but I do not know (epistamai) them, gentlemen"  In some of Plato's dialogues, Socrates appears to credit himself with some knowledge, and can even seem strongly opinionated for a man who professes his own ignorance There are varying explanations of the Socratic inconsistency (other than that Socrates is simply being inconsistent)  One explanation is that Socrates is being either ironic or modest for pedagogical purposes: he aims to let his interlocutor to think for himself rather than guide him to a prefixed answer to his philosophical questions  Another explanation is that Socrates holds different interpretations of the meaning of "knowledge"  Knowledge, for him, might mean systematic understanding of an ethical subject, on which Socrates firmly rejects any kind of mastery; or might refer to lower-level cognition, which Socrates may accept that he possesses  In any case, there is consensus that Socrates accepts that acknowledging one's lack of knowledge is the first step towards wisdom Socrates is known for disavowing knowledge, a claim encapsulated in the saying "I know that I know nothing"  This is often attributed to Socrates on the basis of a statement in Plato's Apology, though the same view is repeatedly found elsewhere in Plato's early writings on Socrates  In other statements, though, he implies or even claims that he does have knowledge  For example, in Plato's Apology Socrates says: "   but that to do injustice and disobey my superior, god or man, this I know to be evil and base   " (Apology, 29b6–7)  In his debate with Callicles, he says: "   I know well that if you will agree with me on those things which my soul believes, those things will be the very truth   "Whether Socrates genuinely thought he lacked knowledge or merely feigned a belief in his own ignorance remains a matter of debate  A common interpretation is that he was indeed feigning modesty  According to Norman Gulley, Socrates did this to entice his interlocutors to speak with him  On the other hand, Terence Irwin claims that Socrates's words should be taken literally Gregory Vlastos argues that there is enough evidence to refute both claims  On his view, for Socrates, there are two separate meanings of "knowledge": Knowledge-C and Knowledge-E (C stands for "certain", and E stands for elenchus, i e  the Socratic method)  Knowledge-C is something unquestionable whereas Knowledge-E is the knowledge derived from Socrates's elenchus  Thus, Socrates speaks the truth when he says he knows-C something, and he is also truthful when saying he knows-E, for example that it is evil for someone to disobey his superiors, as he claims in Apology  Not all scholars have agreed with this semantic dualism  James H  Lesher has argued that Socrates claimed in various dialogues that one word is linked to one meaning (i e  in Hippias Major, Meno, and Laches)  Lesher suggests that although Socrates claimed that he had no knowledge about the nature of virtues, he thought that in some cases, people can know some ethical propositions 

Socratic irony
There is a widespread assumption that Socrates was an ironist, mostly based on the depiction of Socrates by Plato and Aristotle  Socrates's irony is so subtle and slightly humorous that it often leaves the reader wondering if Socrates is making an intentional pun  Plato's Euthyphro is filled with Socratic irony  The story begins when Socrates is meeting with Euthyphro, a man who has accused his own father of murder  When Socrates first hears the details of the story, he comments, "It is not, I think, any random person who could do this [prosecute one's father] correctly, but surely one who is already far progressed in wisdom"  When Euthyphro boasts about his understanding of divinity, Socrates responds that it is "most important that I become your student"  Socrates is commonly seen as ironic when using praise to flatter or when addressing his interlocutors Scholars are divided on why Socrates uses irony  According to an opinion advanced since the Hellenistic period, Socratic irony is a playful way to get the audience's attention  Another line of thought holds that Socrates conceals his philosophical message with irony, making it accessible only to those who can separate the parts of his statements which are ironic from those which are not  Gregory Vlastos has identified a more complex pattern of irony in Socrates  On Vlastos's view, Socrates's words have a double meaning, both ironic and not  One example is when he denies having knowledge  Vlastos suggests that Socrates is being ironic when he says he has no knowledge (where "knowledge" means a lower form of cognition); while, according to another sense of "knowledge", Socrates is serious when he says he has no knowledge of ethical matters  This opinion is not shared by many other scholars 

Socratic eudaimonism and intellectualism
For Socrates, the pursuit of eudaimonia motivates all human action, directly or indirectly  Virtue and knowledge are linked, in Socrates's view, to eudaimonia, but how closely he considered them to be connected is still debated  Some argue that Socrates thought that virtue and eudaimonia are identical  According to another view, virtue serves as a means to eudaimonia (the "identical" and "sufficiency" theses, respectively)  Another point of debate is whether, according to Socrates, people desire what is in fact good—or, rather, simply what they perceive as good Moral intellectualism refers to the prominent role Socrates gave to knowledge  He believed that all virtue was based on knowledge (hence Socrates is characterized as a virtue intellectualist)  He also believed that humans were guided by the cognitive power to comprehend what they desire, while diminishing the role of impulses (a view termed motivational intellectualism)  In Plato's Protagoras (345c4–e6), Socrates implies that "no one errs willingly", which has become the hallmark of Socratic virtue intellectualism  In Socratic moral philosophy, priority is given to the intellect as being the way to live a good life; Socrates deemphasizes irrational beliefs or passions  Plato's dialogues that support Socrates's intellectual motivism—as this thesis is named—are mainly the Gorgias (467c–8e, where Socrates discusses the actions of a tyrant that do not benefit him) and Meno (77d–8b, where Socrates explains to Meno his view that no one wants bad things, unless they do not know what is good and bad in the first place)  Scholars have been puzzled by Socrates's view that akrasia (acting because of one's irrational passions, contrary to one's knowledge or beliefs) is impossible  Most believe that Socrates left no space for irrational desires, although some claim that Socrates acknowledged the existence of irrational motivations, but denied they play a primary role in decision-making 

Religion
Socrates's religious nonconformity challenged the views of his times and his critique reshaped religious discourse for the coming centuries  In Ancient Greece, organized religion was fragmented, celebrated in a number of festivals for specific gods, such as the City Dionysia, or in domestic rituals, and there were no sacred texts  Religion intermingled with the daily life of citizens, who performed their personal religious duties mainly with sacrifices to various gods  Whether Socrates was a practicing man of religion or a 'provocateur atheist' has been a point of debate since ancient times; his trial included impiety accusations, and the controversy has not yet ceased Socrates discusses divinity and the soul mostly in Alcibiades, Euthyphro, and Apology  In Alcibiades Socrates links the human soul to divinity, concluding "Then this part of her resembles God, and whoever looks at this, and comes to know all that is divine, will gain thereby the best knowledge of himself " His discussions on religion always fall under the lens of his rationalism  Socrates, in Euthyphro, reaches a conclusion which takes him far from the age's usual practice: he considers sacrifices to the gods to be useless, especially when they are driven by the hope of receiving a reward in return  Instead he calls for philosophy and the pursuit of knowledge to be the principal way of worshipping the gods  His rejection of traditional forms of piety, connecting them to self-interest, implied that Athenians should seek religious experience by self-examination Socrates argued that the gods were inherently wise and just, a perception far from traditional religion at that time  In Euthyphro, the Euthyphro dilemma arises  Socrates questions his interlocutor about the relationship between piety and the will of a powerful god: Is something good because it is the will of this god, or is it the will of this god because it is good? In other words, does piety follow the good, or the god? The trajectory of Socratic thought contrasts with traditional Greek theology, which took lex talionis (the eye for an eye principle) for granted  Socrates thought that goodness is independent from gods, and gods must themselves be pious Socrates affirms a belief in gods in Plato's Apology, where he says to the jurors that he acknowledges gods more than his accusers  For Plato's Socrates, the existence of gods is taken for granted; in none of his dialogues does he probe whether gods exist or not  In Apology, a case for Socrates being agnostic can be made, based on his discussion of the great unknown after death, and in Phaedo (the dialogue with his students in his last day) Socrates gives expression to a clear belief in the immortality of the soul  He also believed in oracles, divinations and other messages from gods  These signs did not offer him any positive belief on moral issues; rather, they were predictions of unfavorable future events In Xenophon's Memorabilia, Socrates constructs an argument close to the contemporary teleological intelligent-design argument  He claims that since there are many features in the universe that exhibit "signs of forethought" (e g , eyelids), a divine creator must have created the universe  He then deduces that the creator should be omniscient and omnipotent and also that it created the universe for the advance of humankind, since humans naturally have many abilities that other animals do not  At times, Socrates speaks of a single deity, while at other times he refers to plural "gods"  This has been interpreted to mean that he either believed that a supreme deity commanded other gods, or that various gods were parts, or manifestations, of this single deity It has been a source of puzzlement how Socrates's religious beliefs can be consistent with his strict adherence to rationalism  Philosophy professor Mark McPherran suggests that Socrates interpreted every divine sign through secular rationality for confirmation  Professor of ancient philosophy A  A  Long suggests that it is anachronistic to suppose that Socrates believed the religious and rational realms were separate 

Socratic daimonion
In several texts (e g , Plato's Euthyphro 3b5; Apology 31c–d; Xenophon's Memorabilia 1 1 2) Socrates claims he hears a daimōnic sign—an inner voice heard usually when he was about to make a mistake  Socrates gave a brief description of this daimonion at his trial (Apology 31c–d): "   The reason for this is something you have heard me frequently mention in different places—namely, the fact that I experience something divine and daimonic, as Meletus has inscribed in his indictment, by way of mockery  It started in my childhood, the occurrence of a particular voice  Whenever it occurs, it always deters me from the course of action I was intending to engage in, but it never gives me positive advice  It is this that has opposed my practicing politics, and I think its doing so has been absolutely fine " Modern scholarship has variously interpreted this Socratic daimōnion as a rational source of knowledge, an impulse, a dream or even a paranormal experience felt by an ascetic Socrates 

Virtue and knowledge
Socrates's theory of virtue states that all virtues are essentially one, since they are a form of knowledge  For Socrates, the reason a person is not good is because they lack knowledge  Since knowledge is united, virtues are united as well  Another famous dictum—"no one errs willingly"—also derives from this theory  In Protagoras, Socrates argues for the unity of virtues using the example of courage: if someone knows what the relevant danger is, they can undertake a risk  Aristotle comments: "     Socrates the elder thought that the end of life was knowledge of virtue, and he used to seek for the definition of justice, courage, and each of the parts of virtue, and this was a reasonable approach, since he thought that all virtues were sciences, and that as soon as one knew [for example] justice, he would be just   "

Some texts suggest that Socrates had love affairs with Alcibiades and other young persons; others suggest that Socrates's friendship with young boys sought only to improve them and were not sexual  In Gorgias, Socrates claims he was a dual lover of Alcibiades and philosophy, and his flirtatiousness is evident in Protagoras, Meno (76a–c) and Phaedrus (227c–d)  However, the exact nature of his relationship with Alcibiades is not clear; Socrates was known for his self-restraint, while Alcibiades admits in the Symposium that he had tried to seduce Socrates but failed The Socratic theory of love is mostly deduced from Lysis, where Socrates discusses love at a wrestling school in the company of Lysis and his friends  They start their dialogue by investigating parental love and how it manifests with respect to the freedom and boundaries that parents set for their children  Socrates concludes that if Lysis is utterly useless, nobody will love him—not even his parents  While most scholars believe this text was intended to be humorous, it has also been suggested that Lysis shows Socrates held an egoistic view of love, according to which we only love people who are useful to us in some way  Other scholars disagree with this view, arguing that Socrates's doctrine leaves room for non-egoistic love for a spouse; still others deny that Socrates suggests any egoistic motivation at all  In Symposium, Socrates argues that children offer the false impression of immortality to their parents, and this misconception yields a form of unity among them  Scholars also note that for Socrates, love is rational It is notable that Socrates, who claims to know only that he does not know, makes an exception (in Plato's Symposium), where he says he will tell the truth about Love, which he learned from a 'clever woman'  Classicist Armand D'Angour has made the case that Socrates was in his youth close to Aspasia, and that Diotima, to whom Socrates attributes his understanding of love in Symposium, is based on her; however, it is also possible that Diotima really existed 

Socratic philosophy of politics
While Socrates was involved in public political and cultural debates, it is hard to define his exact political philosophy  In Plato's Gorgias, he tells Callicles: "I believe that I'm one of a few Athenians—so as not to say I'm the only one, but the only one among our contemporaries—to take up the true political craft and practice the true politics  This is because the speeches I make on each occasion do not aim at gratification but at what's best " His claim illustrates his aversion for the established democratic assemblies and procedures such as voting—since Socrates saw politicians and rhetoricians as using tricks to mislead the public  He never ran for office or suggested any legislation  Rather, he aimed to help the city flourish by "improving" its citizens  As a citizen, he abided by the law  He obeyed the rules and carried out his military duty by fighting wars abroad  His dialogues, however, make little mention of contemporary political decisions, such as the Sicilian Expedition Socrates spent his time conversing with citizens, among them powerful members of Athenian society, scrutinizing their beliefs and bringing the contradictions of their ideas to light  Socrates believed he was doing them a favor since, for him, politics was about shaping the moral landscape of the city through philosophy rather than electoral procedures  There is a debate over where Socrates stood in the polarized Athenian political climate, which was divided between oligarchs and democrats  While there is no clear textual evidence, one widely held theory holds that Socrates leaned towards democracy: he disobeyed the one order that the oligarchic government of the Thirty Tyrants gave him; he respected the laws and political system of Athens (which were formulated by democrats); and, according to this argument, his affinity for the ideals of democratic Athens was a reason why he did not want to escape prison and the death penalty  On the other hand, there is some evidence that Socrates leaned towards oligarchy: most of his friends supported oligarchy, he was contemptuous of the opinion of the many and was critical of the democratic process, and Protagoras shows some anti-democratic elements  A less mainstream argument suggests that Socrates favoured democratic republicanism, a theory that prioritizes active participation in public life and concern for the city Yet another suggestion is that Socrates endorsed views in line with liberalism, a political ideology formed in the Age of Enlightenment  This argument is mostly based on Crito and Apology, where Socrates talks about the mutually beneficial relationship between the city and its citizens  According to Socrates, citizens are morally autonomous and free to leave the city if they wish—but, by staying within the city, they also accept the laws and the city's authority over them  On the other hand, Socrates has been seen as the first proponent of civil disobedience  Socrates's strong objection to injustice, along with his refusal to serve the Thirty Tyrants' order to arrest Leon, are suggestive of this line  As he says in Critias, "One ought never act unjustly, even to repay a wrong that has been done to oneself " Ιn the broader picture, Socrates's advice would be for citizens to follow the orders of the state, unless, after much reflection, they deem them to be unjust 

Legacy
Hellenistic era
Socrates's impact was immense in philosophy after his death  With the exception of the Epicureans and the Pyrrhonists, almost all philosophical currents after Socrates traced their roots to him: Plato's Academy, Aristotle's Lyceum, the Cynics, and the Stoics  Interest in Socrates kept increasing until the third century AD  The various schools differed in response to fundamental questions such as the purpose of life or the nature of arete (virtue), since Socrates had not handed them an answer, and therefore, philosophical schools subsequently diverged greatly in their interpretation of his thought  He was considered to have shifted the focus of philosophy from a study of the natural world, as was the case for pre-Socratic philosophers, to a study of human affairs Immediate followers of Socrates were his pupils, Euclid of Megara, Aristippus, and Antisthenes, who drew differing conclusions among themselves and followed independent trajectories  The full doctrines of Socrates's pupils are difficult to reconstruct  Antisthenes had a profound contempt of material goods  According to him, virtue was all that mattered  Diogenes and the Cynics continued this line of thought  On the opposite end, Aristippus endorsed the accumulation of wealth and lived a luxurious life  After leaving Athens and returning to his home city of Cyrene, he founded the Cyrenaic philosophical school which was based on hedonism, and endorsing living an easy life with physical pleasures  His school passed to his grandson, bearing the same name  There is a dialogue in Xenophon's work in which Aristippus claims he wants to live without wishing to rule or be ruled by others  In addition, Aristippus maintained a skeptical stance on epistemology, claiming that we can be certain only of our own feelings  This view resonates with the Socratic understanding of ignorance  Euclid was a contemporary of Socrates  After Socrates's trial and death, he left Athens for the nearby town of Megara, where he founded a school, named the Megarians  His theory was built on the pre-Socratic monism of Parmenides  Euclid continued Socrates's thought, focusing on the nature of virtue 
The Stoics relied heavily on Socrates  They applied the Socratic method as a tool to avoid inconsistencies  Their moral doctrines focused on how to live a smooth life through wisdom and virtue  The Stoics assigned virtue a crucial role in attaining happiness and also prioritized the relation between goodness and ethical excellence, all of which echoed Socratic thought  At the same time, the philosophical current of Platonism claimed Socrates as its predecessor, in ethics and in its theory of knowledge  Arcesilaus, who became the head of the Academy about 80 years after its founding by Plato, radically changed the Academy's doctrine to what is now known as Academic Skepticism, centered on the Socratic philosophy of ignorance  The Academic Skeptics competed with the Stoics over who was Socrates's true heir with regard to ethics  While the Stoics insisted on knowledge-based ethics, Arcesilaus relied on Socratic ignorance  The Stoics' reply to Arcesilaus was that Socratic ignorance was part of Socratic irony (they themselves disapproved the use of irony), an argument that ultimately became the dominant narrative of Socrates in later antiquity While Aristotle considered Socrates an important philosopher, Socrates was not a central figure in Aristotelian thought  One of Aristotle's pupils, Aristoxenus even authored a book detailing Socrates's scandals 
The Epicureans were antagonistic to Socrates  They attacked him for superstition, criticizing his belief in his daimonion and his regard for the oracle at Delphi  They also criticized Socrates for his character and various faults, and focusing mostly on his irony, which was deemed inappropriate for a philosopher and unseemly for a teacher The Pyrrhonists were also antagonistic to Socrates, accusing him of being a prater about ethics, who engaged in mock humility, and who sneered at and mocked people 

Medieval world
Socratic thought found its way to the Islamic Middle East alongside that of Aristotle and the Stoics  Plato's works on Socrates, as well as other ancient Greek literature, were translated into Arabic by early Muslim scholars such as Al-Kindi, Jabir ibn Hayyan, and the Muʿtazila  For Muslim scholars, Socrates was hailed and admired for combining his ethics with his lifestyle, perhaps because of the resemblance in this regard with Muhammad's personality  Socratic doctrines were altered to match Islamic faith: according to Muslim scholars, Socrates made arguments for monotheism and for the temporality of this world and rewards in the next life  His influence in the Arabic-speaking world continues to the present day In medieval times, little of Socrates's thought survived in the Christian world as a whole; however, works on Socrates from Christian scholars such as Lactantius, Eusebius and Augustine were maintained in the Byzantine Empire, where Socrates was studied under a Christian lens  After the fall of Constantinople, many of the texts were brought back into the world of Roman Christianity, where they were translated into Latin  Overall, ancient Socratic philosophy, like the rest of classical literature before the Renaissance, was addressed with skepticism in the Christian world at first During the early Italian Renaissance, two different narratives of Socrates developed  On the one hand, the humanist movement revived interest in classical authors  Leonardo Bruni translated many of Plato's Socratic dialogues, while his pupil Giannozzo Manetti authored a well-circulated book, a Life of Socrates  They both presented a civic version of Socrates, according to which Socrates was a humanist and a supporter of republicanism  Bruni and Manetti were interested in defending secularism as a non-sinful way of life; presenting a view of Socrates that was aligned with Christian morality assisted their cause  In doing so, they had to censor parts of his dialogues, especially those which appeared to promote homosexuality or any possibility of pederasty (with Alcibiades), or which suggested that the Socratic daimon was a god  On the other hand, a different picture of Socrates was presented by Italian Neoplatonists, led by the philosopher and priest Marsilio Ficino  Ficino was impressed by Socrates's un-hierarchical and informal way teaching, which he tried to replicate  Ficino portrayed a holy picture of Socrates, finding parallels with the life of Jesus Christ  For Ficino and his followers, Socratic ignorance signified his acknowledgement that all wisdom is God-given (through the Socratic daimon) 

Modern times
In early modern France, Socrates's image was dominated by features of his private life rather than his philosophical thought, in various novels and satirical plays  Some thinkers used Socrates to highlight and comment upon controversies of their own era, like Théophile de Viau who portrayed a Christianized Socrates accused of atheism, while for Voltaire, the figure of Socrates represented a reason-based theist  Michel de Montaigne wrote extensively on Socrates, linking him to rationalism as a counterweight to contemporary religious fanatics In the 18th century, German idealism revived philosophical interest in Socrates, mainly through Hegel's work  For Hegel, Socrates marked a turning point in the history of humankind by the introduction of the principle of free subjectivity or self-determination  While Hegel hails Socrates for his contribution, he nonetheless justifies the Athenian court, for Socrates's insistence upon self-determination would be destructive of the Sittlichkeit (a Hegelian term signifying the way of life as shaped by the institutions and laws of the State)  Also, Hegel sees the Socratic use of rationalism as a continuation of Protagoras' focus on human reasoning (as encapsulated in the motto homo mensura: "man is the measure of all things"), but modified: it is our reasoning that can help us reach objective conclusions about reality  Also, Hegel considered Socrates as a predecessor of later ancient skeptic philosophers, even though he never clearly explained why Søren Kierkegaard considered Socrates his teacher, and authored his master's thesis on him, The Concept of Irony with Continual Reference to Socrates  There he argues that Socrates is not a moral philosopher but is purely an ironist  He also focused on Socrates's avoidance of writing: for Kierkegaard, this avoidance was a sign of humility, deriving from Socrates's acceptance of his ignorance  Not only did Socrates not write anything down, according to Kierkegaard, but his contemporaries misconstrued and misunderstood him as a philosopher, leaving us with an almost impossible task in comprehending Socratic thought  Only Plato's Apology was close to the real Socrates, in Kierkegaard's view  In his writings, he revisited Socrates quite frequently; in his later work, Kierkegaard found ethical elements in Socratic thought  Socrates was not only a subject of study for Kierkegaard, he was a model as well: Kierkegaard paralleled his task as a philosopher to Socrates  He writes, "The only analogy I have before me is Socrates; my task is a Socratic task, to audit the definition of what it is to be a Christian", with his aim being to bring society closer to the Christian ideal, since he believed that Christianity had become a formality, void of any Christian essence  Kierkegaard denied being a Christian, as Socrates denied possessing any knowledge Friedrich Nietzsche resented Socrates's contributions to Western culture  In his first book, The Birth of Tragedy (1872), Nietzsche held Socrates responsible for what he saw as the deterioration of ancient Greek civilization during the 4th century BC and after  For Nietzsche, Socrates turned the scope of philosophy from pre-Socratic naturalism to rationalism and intellectualism  He writes: "I conceive of [the Presocratics] as precursors to a reformation of the Greeks: but not of Socrates"; "with Empedocles and Democritus the Greeks were well on their way towards taking the correct measure of human existence, its unreason, its suffering; they never reached this goal, thanks to Socrates"  The effect, Nietzsche proposed, was a perverse situation that had continued down to his day: our culture is a Socratic culture, he believed  In a later publication, The Twilight of the Idols (1887), Nietzsche continued his offensive against Socrates, focusing on the arbitrary linking of reason to virtue and happiness in Socratic thinking  He writes: "I try to understand from what partial and idiosyncratic states the Socratic problem is to be derived: his equation of reason = virtue = happiness  It was with this absurdity of a doctrine of identity that he fascinated: ancient philosophy never again freed itself [from this fascination]"  From the late 19th century until the early 20th, the most common explanation of Nietzsche's hostility towards Socrates was his anti-rationalism; he considered Socrates the father of European rationalism  In the mid-20th century, philosopher Walter Kaufmann published an article arguing that Nietzsche admired Socrates  Current mainstream opinion is that Nietzsche was ambivalent towards Socrates 

Continental philosophers Hannah Arendt, Leo Strauss and Karl Popper, after experiencing the horrors of World War II, amidst the rise of totalitarian regimes, saw Socrates as an icon of individual conscience  Arendt, in Eichmann in Jerusalem (1963), suggests that Socrates's constant questioning and self-reflection could prevent the banality of evil  Strauss considers Socrates's political thought as paralleling Plato's  He sees an elitist Socrates in Plato's Republic as exemplifying why the polis is not, and could not be, an ideal way of organizing life, since philosophical truths cannot be digested by the masses  Popper takes the opposite view: he argues that Socrates opposes Plato's totalitarian ideas  For Popper, Socratic individualism, along with Athenian democracy, imply Popper's concept of the "open society" as described in his Open Society and Its Enemies (1945)

The 50th Law
The 50th Law is a New York Times bestselling book on strategy and fearlessness written collaboratively by rapper 50 Cent and author Robert Greene  The book is a semi-autobiographical account detailing 50 Cent's rise as both a young urban hustler and as an up-and-coming musician with lessons and anecdotes from historical figures such as Abraham Lincoln, Sun Tzu, Socrates, Napoleon, Malcolm X, and James Baldwin 

Origins
The 50th Law grew out of the friendship and mutual admiration between 50 Cent and Robert Greene  Greene's book The 48 Laws of Power, which has long been a staple in the hip hop world, came to the attention of 50 Cent, who asked his manager to arrange a meeting  Greene said that he was surprised by 50 Cent's persona and was impressed by his "Zen-like calmness" and eye for strategy  The two began to work on a book project that would combine their two worlds According to Greene, 50 Cent is an example of what Machiavelli called a New Prince, a leader who emerges in a time of chaos or turmoil and rewrites the rules  According to 50 Cent, Greene's books describe the laws and strategies used by hustlers on the street, even if they might not know the "technical terms" for what they were doing 

Synopsis
Each of the 10 chapters in the book explains a factor of fearlessness and begins by telling how 50 Cent learned this Fearless Philosophy in Southside Queens  The 50th Law illustrates the laws of the book by supplementing anecdotes from 50 Cent's life with historical examples from Malcolm X, Miles Davis, Sun Tzu, François de La Rochefoucauld, Machiavelli, Richard Wright, James Baldwin, Thucydides, Dostoyevsky, Charlie Parker, and the Baron de Montesquieu 

Reception
The book debuted at #5 on The New York Times Bestseller list and was a USA Today bestseller  The book was met with positive reviews, with the New York Post calling The 50th Law "a modern day Art of War," The Guardian referring to the book as "a manual on power similar to the works of Machiavelli and Sun Tzu," and Library Journal stating that The 50th Law is written for "anyone interested in how to succeed in business and the game of life "The book was also featured in The New York Times, MSNBC, Huffington Post, The Sun, The New York Daily News, Forbes, Business Insider, Fast Company, The Telegraph, MTV, Vibe and Billboard  In promotion of the book, Greene and 50 Cent appeared on The Today Show, CNBC, ABC, BBC and MTV News  The 50th Law was also published as a 60-page comic book

Trust Me, I'm Lying
Trust Me, I'm Lying: Confessions of a Media Manipulator is a book by Ryan Holiday chronicling  his time working as a media strategist for clients including  Tucker Max, Robert Greene, and Dov Charney 

Background and description
Trust Me, I'm Lying was billed as an exposé of the  online journalism system that rose to prominence in the decade before the book's 2012 publication 
Holiday is the former Director of Marketing for American Apparel, where he created controversial campaigns that garnered widespread publicity  Holiday has also done publicity work for Tucker Max, including marketing for the film adaptation of I Hope They Serve Beer in Hell and a media stunt about Max's failed attempt to donate $500,000 to Planned Parenthood The book is split into two parts: the first explains why blogs matter, how they drive the news, and how they can be manipulated, while the second shows what happens when this is done, how it backfires, and the consequences of the current media system As an example of his argument that blogs shape the news, Holiday outlines how the political blog Politico dedicated significant coverage to the campaign of Tim Pawlenty two years before the 2012 elections in order to generate pageviews for advertisers  Although Pawlenty did not yet have an official campaign, this kickstarted the media cycle which painted Pawlenty as a serious presidential candidate  As an example of the pageview-intensive blogosphere, Holiday uses the example of Jezebel writer Irin Carmon's attack on Jon Stewart and The Daily Show with misleading claims of "The Daily Show's Woman Problem " The book is also the source of a marketing and media concept now referred to as "trading up the chain", in which news is broken on small blogs and passed to successively larger and more influential media outlets 

Release
In 2011, it was reported that Holiday received a $500,000 advance for a tell-all exposé about these clients and the modern media system from Portfolio, a subsidiary of Penguin Books  However, some outlets later accused the advance of being a strategic marketing stunt engineered by Holiday Trust Me, I'm Lying debuted on the Wall Street Journal bestseller list  Publishers Weekly stated that "Media students and bloggers would do well to heed Holiday's informative, timely, and provocative advice " Kirkus Reviews called Trust Me, I'm Lying "[a] sharp and disturbing look into the world of online reality "In anticipation of the book's release, Holiday infiltrated the public relations service Help a Reporter Out and posed as an "expert" on various issues to show that journalists will print statements without fact checking  Holiday made decoy claims to prove the point; some of those were subsequently quoted in articles about subjects ranging from boating upkeep to insomnia to vinyl records in outlets such as The New York Times, MSNBC, and ABC, and the story was profiled in Forbes and Yahoo! News In 2013, The Edmonton Journal named Trust Me, I'm Lying one of their “favourite books of the year ”

The Nasty Bits
The Nasty Bits: Collected Varietal Cuts, Usable Trim, Scraps, and Bones, is a largely nonfiction New York Times bestselling book by Anthony Bourdain, published in 2006  The book is a collection of 37 exotic, provocative, and humorous anecdotes and essays, many of them centered around food, followed by a 30-page fiction piece ("A Chef's Christmas")  The book concludes with an appendix of commentaries on the various pieces, including when and why they were written The essays range from descriptions of restaurant-kitchen life; to various rants about places, people, and things Bourdain objects to; to lively accounts of far-flung world travels and remote ethnic life and food; to accolades of the unsung Latinos who cook most fine-dining restaurant food in America; to glowing reports of cutting-edge chefs like Ferran Adrià; to details of Bourdain's obsessions and pursuits when he is not working; to opinions and anecdotes on various other subjects 
Bourdain organized the various essays and anecdotes into sections named for each of the five traditional flavors:

Salty
Sweet
Sour
Bitter
UmamiThe book is, according to Bourdain, basically a collection of the best of his magazine and newspaper writings during the previous few years  As he says in the preface:

I've done a lot of writing for magazines and newspapers in the last few years, and it's the better morsels (I hope) from that work that follow       I've been writing this stuff for much the same reason behind my frenetic traveling: Because I can  Because there's so little time  Because there's been so much to see and remember      It's an irritating reality that many places and events defy description  Angkor Wat and Machu Picchu, for instance, seem to demand silence, like a love affair you can never talk about  For a while after, you fumble for words, trying vainly to assemble a private narrative, an explanation, a comfortable way to frame where you've been and what's happened  In the end, you're just happy you were there—with your eyes open—and lived to see it

Gary L  Bennett
Gary L  Bennett (born January 17, 1940) is an American scientist and engineer, specializing in aerospace and energy   He has worked for NASA and the US Department of Energy (DOE) on advanced space power systems and advanced space propulsion systems   His professional career has included work on the Voyager, Galileo, and Ulysses space missions, and is currently working as a consultant in aerospace power and propulsion systems  He is also a science fiction author (The Star Sailors) 

Biography
Bennett was born in Twin Falls, Idaho  He joined the NASA headquarters in June 1988 as the Manager of Advanced Space Power Systems in the transportation division of the Office of Advanced Concepts and Technology  There, he managed a number of transportation technology programs including hybrid propulsion, electric propulsion, low-thrust chemical propulsion, and other advanced propulsion concepts (e g , fusion, antimatter)  He was also the first program manager of the advanced technology insertion program for the Pluto Fast Flyby (now New Horizons) mission and the TIMED space physics mission 
Prior to coming to NASA, Bennett held key positions in DoE's space radioisotope power program, including serving as Director of Safety and Nuclear Operations for the radioisotope power sources that were used on the Galileo mission to Jupiter and that are being used on the Ulysses mission to explore the polar regions of the Sun   This same radioisotope power source design was then flown on the Cassini mission to Saturn and on the New Horizons mission to Jupiter 
Previous positions included Chief of the Research Support Branch in the US Nuclear Regulatory Commission (NRC) where Bennett was instrumental in creating and managing NRC's reactor operational safety research program 
Bennett was the flight safety manager for the radioisotope power sources currently in use on the Voyager 1 and Voyager 2 spacecraft (which went to Jupiter, Saturn, Uranus, Neptune and beyond) and on Lincoln Laboratory's LES 8 and LES 9 communications satellites 
Bennett also worked as a physicist in the NERVA (Nuclear Engine for Rocket Vehicle Applications) program at what was then NASA's Lewis Research Center (now the John H  Glenn Research Center) in Cleveland, Ohio   He did fundamental reactor safety research at what is now the Department of Energy's Idaho National Laboratory (INL) 
From 1980 to 1988, he was a member of or adviser to US delegations to the two subcommittees of the United Nations Committee on the Peaceful Uses of Outer Space and he prepared the official US position papers on the use of nuclear power sources in outer space 
From 1988 to 1990, Bennett chaired the Steering Group of the Interagency Advanced Power Group (IAPG), the national coordinating group for federally sponsored space and terrestrial power research   During his tenure and under his initiative the IAPG saw its greatest increase in membership 
Bennett received his PhD in physics from Washington State University in 1970; a Master of Nuclear Science degree in 1966, and a BSc degree in physics from the University of Idaho in 1962; and an Associate of Arts degree from Boise Junior College (now Boise State University) in 1960 
Since 1995, he has been active in promoting the teaching of science (specifically evolution) and received the Friend of Darwin Award  Bennett has also been a champion of the First Amendment and was elected to the National Advisory Council of Americans United for Separation of Church and State

Passage 2:
Planetary protection
Planetary protection is a guiding principle in the design of an interplanetary mission, aiming to prevent biological contamination of both the target celestial body and the Earth in the case of sample-return missions  Planetary protection reflects both the unknown nature of the space environment and the desire of the scientific community to preserve the pristine nature of celestial bodies until they can be studied in detail There are two types of interplanetary contamination  Forward contamination is the transfer of viable organisms from Earth to another celestial body   Back contamination is the transfer of extraterrestrial organisms, if they exist, back to the Earth's biosphere 

History
The potential problem of lunar and planetary contamination was first raised at the International Astronautical Federation VIIth Congress in Rome in 1956 In 1958 the U S  National Academy of Sciences (NAS) passed a resolution stating, “The National Academy of Sciences of the United States of America urges that scientists plan lunar and planetary studies with great care and deep concern so that initial operations do not compromise and make impossible forever after critical scientific experiments ” This led to creation of the ad hoc Committee on Contamination by Extraterrestrial Exploration (CETEX), which met for a year and recommended that interplanetary spacecraft be sterilized, and stated, “The need for sterilization is only temporary  Mars and possibly Venus need to remain uncontaminated only until study by manned ships becomes possible” In 1959, planetary protection was transferred to the newly formed Committee on Space Research (COSPAR)  COSPAR in 1964 issued Resolution 26 affirming that:

the search for extraterrestrial life is an important objective of space research, that the planet of Mars may offer the only feasible opportunity to conduct this search during the foreseeable future, that contamination of this planet would make such a search far more difficult and possibly even prevent for all time an unequivocal result, that all practical steps should be taken to ensure that Mars be not biologically contaminated until such time as this search has been satisfactorily carried out, and that cooperation in proper scheduling of experiments and use of adequate spacecraft sterilization techniques is required on the part of all deep space probe launching authorities to avoid such contamination 
In 1967, the US, USSR, and UK ratified the United Nations Outer Space Treaty   The legal basis for planetary protection lies in Article IX of this treaty:
"Article IX:     States Parties to the Treaty shall pursue studies of outer space, including the Moon and other celestial bodies, and conduct exploration of them so as to avoid their harmful contamination and also adverse changes in the environment of the Earth resulting from the introduction of extraterrestrial matter and, where necessary, shall adopt appropriate measures for this purpose    
This treaty has since been signed and ratified by 104 nation-states  Another 24 have signed but not ratified   All the current space-faring nation-states, along with all current aspiring space-faring nation-states, have both signed and ratified the treaty The Outer Space Treaty has consistent and widespread international support, and as a result of this, together with the fact that it is based on the 1963 declaration which was adopted by consensus in the UN National Assembly, it has taken on the status of customary international law  The provisions of the Outer Space Treaty are therefore binding on all states, even those who have neither signed nor ratified it For forward contamination, the phrase to be interpreted is "harmful contamination"   Two legal reviews came to differing interpretations of this clause (both reviews were unofficial)  However the currently accepted interpretation is that “any contamination which would result in harm to a state’s experiments or programs is to be avoided”  NASA policy states explicitly that “the conduct of scientific investigations of possible extraterrestrial life forms, precursors, and remnants must not be jeopardized” 

COSPAR recommendations and categories
The Committee on Space Research (COSPAR) meets every two years, in a gathering of 2000 to 3000 scientists, and one of its tasks is to develop recommendations for avoiding interplanetary contamination  Its legal basis is Article IX of the Outer Space Treaty  (see history below for details) 
Its recommendations depend on the type of space mission and the celestial body explored   COSPAR categorizes the missions into 5 groups:

Category I: Any mission to locations not of direct interest for chemical evolution or the origin of life, such as the  Sun or Mercury  No planetary protection requirements 
Category II: Any mission to locations of significant interest for chemical evolution and the origin of life, but only a remote chance that spacecraft-borne contamination could compromise investigations  Examples include the Moon, Venus, and comets  Requires simple documentation only, primarily to outline intended or potential impact targets, and an end of mission report of any inadvertent impact site if such occurred 
Category III: Flyby and orbiter missions to locations of significant interest for chemical evolution or the origin of life, and with a significant chance that contamination could compromise investigations e g , Mars, Europa, Enceladus  Requires more involved documentation than Category II  Other requirements, depending on the mission, may include trajectory biasing, clean room assembly, bioburden reduction, and if impact is a possibility, inventory of organics 
Category IV: Lander or probe missions to the same locations as Category III  Measures to be applied depend on the target body and the planned operations  "Sterilization of the entire spacecraft may be required for landers and rovers with life-detection experiments, and for those landing in or moving to a region where terrestrial microorganisms may survive and grow, or where indigenous life may be present  For other landers and rovers, the requirements would be for decontamination and partial sterilization of the landed hardware "Missions to Mars in category IV are subclassified further:Category IVa  Landers that do not search for Martian life - uses the Viking lander pre-sterilization requirements, a maximum of 300,000 spores per spacecraft and 300 spores per square meter 
Category IVb  Landers that search for Martian life   Adds stringent extra requirements to prevent contamination of samples 
Category IVc  Any component that accesses a Martian special region (see below) must be sterilized to at least to the Viking post-sterilization biological burden levels of 30 spores total per spacecraft Category V: This is further divided into unrestricted and restricted sample return Unrestricted Category V: samples from locations judged by scientific opinion to have no indigenous lifeforms  No special requirements 
Restricted Category V: (where scientific opinion is unsure) the requirements include: absolute prohibition of destructive impact upon return, containment of all returned hardware which directly contacted the target body, and containment of any unsterilized sample returned to Earth For Category IV missions, a certain level of biological burden is allowed for the mission  In general this is expressed as a 'probability of contamination', required to be less than one chance in 10,000 of forward contamination per mission, but in the case of Mars Category IV missions (above) the requirement has been translated into a count of Bacillus spores per surface area, as an easy to use assay method More extensive documentation is also required for Category IV  Other procedures required, depending on the mission, may include trajectory biasing, the use of clean rooms during spacecraft assembly and testing, bioload reduction, partial sterilization of the hardware having direct contact with the target body, a bioshield for that hardware, and, in rare cases, complete sterilization of the entire spacecraft For restricted Category V missions, the current recommendation is that no uncontained samples should be returned unless sterilized  Since sterilization of the returned samples would destroy much of their science value, current proposals involve containment and quarantine procedures  For details, see Containment and quarantine below  Category V missions also have to fulfill the requirements of Category IV to protect the target body from forward contamination 

Mars special regions
A special region is a region classified by COSPAR where terrestrial organisms could readily propagate, or thought to have a high potential for existence of Martian life forms  This is understood to apply to any region on Mars where liquid water occurs, or can occasionally occur, based on the current understanding of requirements for life 
If a hard landing risks biological contamination of a special region, then the whole lander system must be sterilized to COSPAR category IVc 

Target categories
Some targets are easily categorized  Others are assigned provisional categories by COSPAR, pending future discoveries and research 
The 2009 COSPAR Workshop on Planetary Protection for Outer Planet Satellites and Small Solar System Bodies covered this in some detail  Most of these assessments are from that report, with some future refinements  This workshop also gave more precise definitions for some of the categories:

Category I
“not of direct interest for understanding the process of chemical evolution or the origin of life ” 
Io, Sun, Mercury, undifferentiated metamorphosed asteroids

Category II
… where there is only a remote chance that contamination carried by a spacecraft could jeopardize future exploration”  In this case we define “remote chance” as “the absence of niches (places where terrestrial microorganisms could proliferate) and/or a very low likelihood of transfer to those places ” 
Callisto, comets, asteroids of category P, D, and C, Venus, Kuiper belt objects (KBO) < 1/2 size of Pluto 

Provisional Category II
Ganymede, Titan, Triton, the Pluto–Charon system, and other large KBOs (> 1/2 size of Pluto), CeresProvisionally, they assigned these objects to Category II  However, they state that more research is needed, because there is a remote possibility that the tidal interactions of Pluto and Charon could maintain some water reservoir below the surface  Similar considerations apply to the other larger KBOs 
Triton is insufficiently well understood at present to say it is definitely devoid of liquid water  The only close up observations to date are those of Voyager 2 
In a detailed discussion of Titan, scientists concluded that there was no danger of contamination of its surface, except short term adding of negligible amounts of organics, but Titan could have a below surface water reservoir that communicates with the surface, and if so, this could be contaminated 
In the case of Ganymede, the question is, given that its surface shows pervasive signs of resurfacing, is there any communication with its subsurface ocean? They found no known mechanism by which this could happen, and the Galileo spacecraft found no evidence of cryovolcanism  Initially, they assigned it as Priority B minus, meaning that precursor missions are needed to assess its category before any surface missions  However, after further discussion they provisionally assigned it to Category II, so no precursor missions are required, depending on future research 
If there is cryovolcanism on Ganymede or Titan, the undersurface reservoir is thought to be 50 – 150 km below the surface  They were unable to find a process that could transfer the surface melted water back down through 50 km of ice to the under surface sea  This is why both Ganymede and Titan were assigned a reasonably firm provisional Category II, but pending results of future research 
Icy bodies that show signs of recent resurfacing need further discussion and might need to be assigned to a new category depending on future research  This approach has been applied, for instance, to missions to Ceres  The planetary protection Category is subject for review during the mission of the Ceres orbiter (Dawn) depending on the results found 

Category III / IV
“…where there is a significant chance that contamination carried by a spacecraft could jeopardize future exploration ” We define “significant chance” as “the presence of niches (places where terrestrial microorganisms could proliferate) and the likelihood of transfer to those places ” 
Mars because of possible subsurface habitats 
Europa because of its subsurface ocean 
Enceladus because of evidence of water plumes 

Category V
Unrestricted Category V: “Earth-return missions from bodies deemed by scientific opinion to have no indigenous life forms ”
Restricted Category V: "Earth-return missions from bodies deemed by scientific opinion to be of significant interest to the process of chemical evolution or the origin of life "
In the category V for sample return the conclusions so far are:
Unrestricted Category V: Venus, the Moon 
Restricted Category V: Mars, Europa, Enceladus 

The Coleman–Sagan equation
The aim of the current regulations is to keep the number of microorganisms low enough so that the probability of contamination of Mars (and other targets) is acceptable  It is not an objective to make the probability of contamination zero 
The aim is to keep the probability of contamination of 1 chance in 10,000 of contamination per mission flown  This figure is obtained typically by multiplying together the number of microorganisms on the spacecraft, the probability of growth on the target body, and a series of bioload reduction factors 
In detail the method used is the Coleman–Sagan equation

   is a number chosen by Sagan et al , somewhat arbitrarily  Sagan and Coleman assumed that about 60 missions to the Mars surface would occur before the exobiology of Mars is thoroughly understood, 54 of those successful, and 30 flybys or orbiters, and the number was chosen to endure a probability to keep the planet free from contamination of at least 99 9% over the duration of the exploration period 

Critiques
The Coleman–Sagan equation has been criticised because the individual parameters are often not known to better than a magnitude or so  For example, the thickness of the surface ice of Europa is unknown, and may be thin in places, which can give rise to a high level of uncertainty in the equation  It has also been criticised because of the inherent assumption made of an end to the protection period and future human exploration  In the case of Europa, this would only protect it with reasonable probability for the duration of the period of exploration Greenberg has suggested an alternative, to use the natural contamination standard — that our missions to Europa should not have a higher chance of contaminating it than the chance of contamination by meteorites from Earth 
As long as the probability of people infecting other planets with terrestrial microbes is substantially smaller than the probability that such contamination happens naturally, exploration activities would, in our view, be doing no harm  We call this concept the natural contamination standard 
Another approach for Europa is the use of binary decision trees which is favoured by the Committee on Planetary Protection Standards for Icy Bodies in the Outer Solar System under the auspices of the Space Studies Board  This goes through a series of seven steps, leading to a final decision on whether to go ahead with the mission or not 
Recommendation: Approaches to achieving planetary protection should not rely on the multiplication of bioload estimates and probabilities to calculate the likelihood of contaminating Solar System bodies with terrestrial organisms unless scientific data unequivocally define the values, statistical variation, and mutual independence of every factor used in the equation Recommendation: Approaches to achieving planetary protection for missions to icy Solar System bodies should employ a series of binary decisions that consider one factor at a time to determine the appropriate level of planetary protection procedures to use 

Containment and quarantine for restricted Category V sample return
In the case of restricted Category V missions, Earth would be protected through quarantine of sample and astronauts in a yet to be built Biosafety level 4 facility  In the case of a Mars sample return, missions would be designed so that no part of the capsule that encounters the Mars surface is exposed to the Earth environment  One way to do that is to enclose the sample container within a larger outer container from Earth, in the vacuum of space  The integrity of any seals is essential and the system must also be monitored to check for the possibility of micro-meteorite damage during return to Earth The recommendation of the ESF report is that
“No uncontained Mars materials, including space craft surfaces that have been exposed to the Mars environment should be returned to Earth unless sterilised"   "For unsterilised samples returned to Earth, a programme of life detection and biohazard testing, or a proven sterilisation process, shall be undertaken as an absolute precondition for the controlled distribution of any portion of the sample ”
No restricted category V returns have been carried out  During the Apollo program, the sample-returns were regulated through the Extra-Terrestrial Exposure Law  This was rescinded in 1991, so new regulations would need to be enacted  The Apollo era quarantine procedures are of interest as the only attempt to date of a return to Earth of a sample that, at the time, was thought to have a remote possibility of including extraterrestrial life 
Samples and astronauts were quarantined in the Lunar Receiving Laboratory  The methods used would be considered inadequate for containment by modern standards  Also the lunar receiving laboratory would be judged a failure by its own design criteria as the sample return didn't contain the lunar material, with two failure points during the Apollo 11 return mission, at the splashdown and at the facility itself 
However the Lunar Receiving Laboratory was built quickly with only two years from start to finish, a time period now considered inadequate  Lessons learned from it can help with design of any Mars sample return receiving facility Design criteria for a proposed Mars Sample Return Facility, and for the return mission, have been developed by the American National Research Council, and the European Space Foundation  They concluded that it could be based on biohazard 4 containment but with more stringent requirements to contain unknown microorganisms possibly as small as or smaller than the smallest Earth microorganisms known, the ultramicrobacteria  The ESF study also recommended that it should be designed to contain the smaller gene transfer agents if possible, as these could potentially transfer DNA from martian microorganisms to terrestrial microorganisms if they have a shared evolutionary ancestry  It also needs to double as a clean room facility to protect the samples from terrestrial contamination that could confuse the sensitive life detection tests that would be used on the samples 
Before a sample return, new quarantine laws would be required  Environmental assessment would also be required, and various other domestic and international laws not present during the Apollo era would need to be negotiated 

Decontamination procedures
For all spacecraft missions requiring decontamination, the starting point is clean room assembly in US federal standard class 100 cleanrooms  These are rooms with fewer than 100 particles of size 0 5 µm or larger per cubic foot  Engineers wear cleanroom suits with only their eyes exposed  Components are sterilized individually before assembly, as far as possible, and they clean surfaces frequently with alcohol wipes during assembly  Spores of Bacillus subtilis was chosen for not only its ability to readily generate spores, but its well-established use as a model species  It is a useful tracker of UV irradiation effects because of its high resilience to a variety of extreme conditions  As such it is an important indicator species for forward contamination in the context of planetary protection 
For Category IVa missions (Mars landers that do not search for Martian life), the aim is to reduce the bioburden to 300,000 bacterial spores on any surface from which the spores could get into the Martian environment  Any heat tolerant components are heat sterilized to 114 °C  Sensitive electronics such as the core box of the rover including the computer, are sealed and vented through high-efficiency filters to keep any microbes inside For more sensitive missions such as Category IVc (to Mars special regions), a far higher level of sterilization is required  These need to be similar to levels implemented on the Viking landers, which were sterilized for a surface which, at the time, was thought to be potentially hospitable to life similar to special regions on Mars today 
In microbiology, it is usually impossible to prove that there are no microorganisms left viable, since many microorganisms are either not yet studied, or not cultivable  Instead, sterilization is done using a series of tenfold reductions of the numbers of microorganisms present  After a sufficient number of tenfold reductions, the chance that there any microorganisms left will be extremely low The two Viking Mars landers were sterilized using dry heat sterilization   After preliminary cleaning to reduce the bioburden to levels similar to present day Category IVa spacecraft, the Viking spacecraft were heat-treated for 30 hours at 112 °C, nominal 125 °C (five hours at 112 °C was considered enough to reduce the population tenfold even for enclosed parts of the spacecraft, so this was enough for a million-fold reduction of the originally low population) Modern materials however are often not designed to handle such temperatures, especially since modern spacecraft often use "commercial off the shelf" components  Problems encountered include nanoscale features only a few atoms thick, plastic packaging, and conductive epoxy attachment methods  Also many instrument sensors cannot be exposed to high temperature, and high temperature can interfere with critical alignments of instruments As a result, new methods are needed to sterilize a modern spacecraft to the higher categories such as Category IVc for Mars, similar to Viking  Methods under evaluation, or already approved, include:

Vapour phase hydrogen peroxide - effective, but can affect finishes, lubricants and materials that use aromatic rings and sulfur bonds  This has been established, reviewed, and a NASA/ESA specification for use of VHP has been approved by the Planetary Protection Officer, but it has not yet been formally published 
Ethylene oxide - this is widely used in the medical industry, and can be used for materials not compatible with hydrogen peroxide  It is under consideration for missions such as ExoMars 
Gamma radiation and electron beams have been suggested as a method of sterilization, as they are used extensively in the medical industry  They need to be tested for compatibility with spacecraft materials and hardware geometries, and are not yet ready for review Some other methods are of interest as they can sterilize the spacecraft after arrival on the planet 
Supercritical carbon dioxide snow (Mars) - is most effective against traces of organic compounds rather than whole microorganisms  Has the advantage though that it eliminates the organic traces - while other methods kill the microorganisms, they leave organic traces that can confuse life detection instruments  Is under study by JPL and ESA 
Passive sterilization through UV radiation (Mars)  Highly effective against many microorganisms, but not all, as a Bacillus strain found in spacecraft assembly facilities is particularly resistant to UV radiation  Is also complicated by possible shadowing by dust and spacecraft hardware 
Passive sterilization through particle fluxes (Europa)  Plans for missions to Europa take credit for reductions due to this 

Bioburden detection and assessment
The spore count is used as an indirect measure of the number of microorganisms present  Typically 99% of microorganisms by species will be non-spore forming and able to survive in dormant states, and so the actual number of viable dormant microorganisms remaining on the sterilized spacecraft is expected to be many times the number of spore-forming microorganisms 
One new spore method approved is the "Rapid Spore Assay"  This is based on commercial rapid assay systems, detects spores directly and not just viable microorganisms and gives results in 5 hours instead of 72 hours 

Challenges
It is also long been recognized that spacecraft cleaning rooms harbour polyextremophiles as the only microbes able to survive in them  For example, in a recent study, microbes from swabs of the Curiosity rover were subjected to desiccation, UV exposure, cold and pH extremes  Nearly 11% of the 377 strains survived more than one of these severe conditions  The genomes of resistant spore producing Bacillus sp  have been studied and genome level traits potentially linked to the resistance have been reported This does not mean that these microbes have contaminated Mars  This is just the first stage of the process of bioburden reduction  To contaminate Mars they also have to survive the low temperature, vacuum, UV and ionizing radiation during the months long journey to Mars, and then have to encounter a habitat on Mars and start reproducing there  Whether this has happened or not is a matter of probability  The aim of planetary protection is to make this probability as low as possible  The currently accepted target probability of contamination per mission is to reduce it to less than 0 01%, though in the special case of Mars, scientists also rely on the hostile conditions on Mars to take the place of the final stage of heat treatment decimal reduction used for Viking  But with current technology scientists cannot reduce probabilities to zero 

New methods
Two recent molecular methods have been approved for assessment of microbial contamination on 
spacecraft surfaces 
Adenosine triphosphate (ATP) detection - this is a key element in cellular metabolism  This method is able to detect non cultivable organisms  It can also be triggered by non viable biological material so can give a "false positive" 
Limulus Amebocyte Lysate assay - detects lipopolysaccharides (LPS)  This compound is only present in Gram-negative bacteria  The standard assay analyses spores from microbes that are primarily Gram-positive, making it difficult to relate the two methods 

Impact prevention
This particularly applies to orbital missions, Category III, as they are sterilized to a lower standard than missions to the surface  It is also relevant to landers, as an impact gives more opportunity for forward contamination, and impact could be on an unplanned target, such as a special region on Mars 
The requirement for an orbital mission is that it needs to remain in orbit for at least 20 years after arrival at Mars with probability of at least 99% and for 50 years with probability at least 95%  This requirement can be dropped if the mission is sterilized to Viking sterilization standard In the Viking era (1970s), the requirement was given as a single figure, that any orbital mission should have a probability of less than 0 003% probability of impact during the current exploratory phase of exploration of Mars For both landers and orbiters, the technique of trajectory biasing is used during approach to the target  The spacecraft trajectory is designed so that if communications are lost, it will miss the target 

Issues with impact prevention
Despite these measures there has been one notable failure of impact prevention  The Mars Climate Orbiter which was sterilized only to Category III, crashed on Mars in 1999 due to a mix-up of imperial and metric units  The office of planetary protection stated that it is likely that it burnt up in the atmosphere, but if it survived to the ground, then it could cause forward contamination Mars Observer is another Category III mission with potential planetary contamination  Communications were lost three days before its orbital insertion maneuver in 1993  It seems most likely it did not succeed in entering into orbit around Mars and simply continued past on a heliocentric orbit  If it did succeed in following its automatic programming, and attempted the manoeuvre, however, there is a chance it crashed on Mars Three landers have had hard landings on Mars   These are Schiaparelli EDM lander, the Mars Polar Lander, and Deep Space 2  These were all sterilized for surface missions but not for special regions (Viking pre-sterilization only)  Mars Polar Lander, and Deep Space 2 crashed into the polar regions which are now treated as special regions because of the possibility of forming liquid brines

Alberto G  Fairén and Dirk Schulze-Makuch published an article in Nature recommending that planetary protection measures need to be scaled down  They gave as their main reason for this, that exchange of meteorites between Earth and Mars means that any life on Earth that could survive on Mars has already got there and vice versa Robert Zubrin used similar arguments in favour of his view that the back contamination risk has no scientific validity 

Rebuttal by NRC
The meteorite argument was examined by the NRC in the context of back contamination  It is thought that all the Martian meteorites originate in relatively few impacts every few million years on Mars  The impactors would be kilometers in diameter and the craters they form on Mars tens of kilometers in diameter  Models of impacts on Mars are consistent with these findings Earth receives a steady stream of meteorites from Mars, but they come from relatively few original impactors, and transfer was more likely in the early Solar System  Also some life forms viable on both Mars and on Earth might be unable to survive transfer on a meteorite, and there is so far no direct evidence of any transfer of life from Mars to Earth in this way 
The NRC concluded that though transfer is possible, the evidence from meteorite exchange does not eliminate the need for back contamination protection methods Impacts on Earth able to send microorganisms to Mars are also infrequent
Context 3: Passage 1:
Anacardiaceae
The Anacardiaceae, commonly known as the cashew family or sumac family, are a family of flowering plants, including about 83 genera with about 860 known species  Members of the Anacardiaceae bear fruits that are drupes and in some cases produce urushiol, an irritant  The Anacardiaceae include numerous genera, several of which are economically important, notably cashew (in the type genus Anacardium), mango, Chinese lacquer tree,  yellow mombin, Peruvian pepper, poison ivy, poison oak, sumac, smoke tree, marula and cuachalalate   The genus Pistacia (which includes the pistachio and mastic tree) is now included, but was previously placed in its own family, the Pistaciaceae 

Description
Trees or shrubs, each has inconspicuous flowers and resinous or milky sap that may be highly poisonous, as in black poisonwood and sometimes foul-smelling Resin canals located in the inner fibrous bark of the fibrovascular system found in the plant's stems, roots, and leaves are characteristic of all members of this family; resin canals located in the pith are characteristic of many of the cashew family species and several species have them located in the primary cortex or the regular bark   Tannin sacs are also widespread among the family The wood of the Anacardiaceae has the frequent occurrence of simple small holes in the vessels, occasionally in some species side by side with scalariform holes (in Campnosperma, Micronychia, and Heeria argentea (Anaphrenium argenteum)   The simple pits are located along the vessel wall and in contact with the parenchyma Leaves are deciduous or evergreen, usually alternate (rarely opposite), estipulate (without stipule) and imparipinnate (rarely paripinnate or bipinnate), usually with opposite leaflets (rarely alternate), while others are trifoliolate or simple or unifoliolate (very rarely simple leaves are palmate)  Leaf architecture is very diverse  Primary venation is pinnate (rarely palmate)  Secondary venation is eucamptodromous, brochidodromous, craspedodromous or cladodromous (rarely reticulodromous) Cladodromous venation, if present is considered diagnostic for Anacardiaceae Flowers grow at the end of a branch or stem or at an angle from where the leaf joins the stem and have bracts 
Often with this family, bisexual and male flowers occur on some plants, and bisexual and female flowers are on others, or flowers have both stamens and pistils (perfect)   A calyx with three to seven cleft sepals and the same number of petals, occasionally no petals, overlap each other in the bud   Stamens are twice as many or equal to the number of petals, inserted at the base of the fleshy ring or cup-shaped disk, and inserted below the pistil(s) 
Stamen stalks are separate, and anthers are able to move 
Flowers have the ovary free, but the petals and stamen are borne on the calyx 
In the stamenate flowers, ovaries are single-celled   In the pistillate flowers, ovaries are single or sometimes quadri- or quinticelled   One to three styles and one ovule occur in each cavity Fruits rarely open at maturity
and are most often drupes Seed coats are very thin or are crust-like  Little or no endosperm is present    Cotyledons are fleshy 
Seeds are solitary with no albumen around the embryo 

Taxonomy
History
In 1759, Bernard de Jussieu arranged the plants in the royal garden of the Trianon at Versailles, according to his own scheme  That classification included a description of an order called the Terebintaceæ, which contained a suborder that included Cassuvium (Anacardium), Anacardium (Semecarpus), Mangifera, Connarus, Rhus, and Rourea   In 1789, Antoine Laurent de Jussieu, nephew of Bernard de Jussieu, published that classification scheme Robert Brown described a subset of the Terebintaceae called Cassuvlæ or Anacardeæ in 1818, using the herbarium that was collected by Christen Smith during a fated expedition headed by James Hingston Tuckey to explore the River Congo   The name and genera were based on the order with the same name that had been described by de Jussieu in 1759   The herbarium from that expedition contained only one genus from the family, Rhus Augustin Pyramus de Candolle in 1824, used Robert Brown's name Cassuvlæ or Anacardeæ, wrote another description of the group, and filled it with the genera Anacardium, Semecarpus, Holigarna, Mangifera, Buchanania, Pistacia, Astronium, Comocladia, and Picramnia John Lindley described the "essential character" of the Anacardiaceæ, the "Cashew Tribe" in 1831, adopting the order that was described by de Jussieu, but abandoning the name Terebintaceæ   He includes the genera that were found in de Candolle's Anacardieæ and Sumachineæ: Anacardium, Holigarna, Mangifera, Rhus, and Mauria 

Phylogeny
The genus Pistacia has sometimes been separated into its own family, the Pistaciaceae, based on the reduced flower structure, differences in pollen, and the feathery style of the flowers The nature of its ovary, though,  does suggest it belongs in the Anacardiaceae, a position supported by morphological and molecular studies, and recent classifications have included Pistacia in the Anacardiaceae  The genus Abrahamia was separated from Protorhus in 2004 (Pell 2004)

Subdivision
The family has been treated as a series of five tribes by Engler, and later into subfamilies by Takhtajan, as Anacardioideae (including tribes Anacardieae, Dobineae, Rhoideae, and Semecarpeae) and Spondiadoideae (including tribe Spondiadeae)  Pell's (2008) molecular analysis reinstated the two subfamilies without further division into tribes (Pell 2004)  Later, Min and Barfod, in the Flora of China (2008) reinstated the five tribes (four in Anacardioideae), and the single tribe Spondiadeae as Spondiadoideae 

Selected genera
Ecology
The cashew family is more abundant in warm or tropical regions with only a few species living in the temperate zones  Mostly native to tropical Americas, Africa and India   Pistacia and some species of Rhus can be found in southern Europe,  Rhus species can be found in much of North America and Schinus inhabits South America exclusively 

Uses
Members of this family produce cashew and pistachio nuts, and mango and marula fruits Some members produce a viscous or adhesive fluid which turns black and is used as a varnish or for tanning and even as a mordant for red dyes  The sap of Toxicodendron vernicifluum is used to make lacquer for lacquerware and similar products 

Etymology
The name Anacardium, originally from the Greek, refers to the nut, core or heart of the fruit, which is outwardly located: ana means "upward" and -cardium means "heart") 
Passage 2:
Commiphora gileadensis
Commiphora gileadensis, the Arabian balsam tree, is a shrub species in the genus Commiphora growing in Saudi Arabia, Yemen, southern Oman, Sudan and in southeast Egypt where it may have been introduced  Other common names for the plant include balm of Gilead and Mecca myrrh, but this is due to historical confusion between several plants and the historically important expensive perfumes and drugs obtained from them 

True balm of Gilead was very rare, and appears to have been produced from the unrelated tree Pistacia lentiscus  The Commiphora gileadensis species also used to include Commiphora foliacea, however it was identified and described as a separate species

Use
Historical
The plant was renowned for the expensive perfume that was thought to be produced from it, as well as for exceptional medicinal properties that were attributed to its sap, wood, bark, and seeds  Commiphora gileadensis is instantly recognisable by the pleasant smell given out when a twig is broken or a leaf crushed 

Modern
The bark of the balsam tree is cut to cause the sap to flow out  This soon hardens, and has a sweet smell that quickly evaporates  The hardened resinous gum is chewed, is said to taste either like a lemon or like pine resin, and it is also burned as incense 

Description
Depending on where Commiphora gileadensis is growing, it can vary in size, ranging from a small-leaved shrub to a large-leaved tree usually up to 4m tall   It is rarely spiny, bark peeling or flaking when cut and exuding a pleasant smelling resin  Its leaves alternate on short condensed side shoots, pinnate with 3-5 leaflets   The leaflets are oblong, 5-40mm long x 3-35mm across with acute tips and are thinly hairy   The flowers are red, sub-sessile and the plant has 1-5 of them on short condensed side shoots amongst the leaves  The fruits are dull red and marked with four longitudinal white stripes, one-seeded and splitting into 2-4 valves 
Passage 3:
Pistacia
Pistacia is a genus of flowering plants in the cashew family, Anacardiaceae  It contains 10 to 20 species that are native to Africa and Eurasia from the Canary Islands, all of Africa, and southern Europe, warm and semidesert areas across Asia, and North America from Mexico to warm and semidesert United States, such as Texas or California 

Description
Pistacia plants are shrubs and small trees growing to 5–15 m (16–49 ft) tall  The leaves are alternate, pinnately compound, and can be either evergreen or deciduous depending on species  All species are dioecious, but monoecious individuals of Pistacia atlantica have been noted  The genus is estimated to be about 80 million years old It is a genus of flowering plants belonging to the family Anacardiaceae  The plants are dioecious, and have male and female trees independently; a viable population should have both sexes Well-known species in the genus Pistacia include P  vera, the pistachio, grown for its edible seeds; P  terebinthus, from which terebinth resin, a turpentine, is produced; P  lentiscus, source of the plant resin mastic; and P  chinensis, the Chinese pistache, cultivated as an ornamental tree 

P  vera genome
Scientists from Iran and China assembled a draft genome of pistachio and resequenced 107 whole genomes, including 93 domestic and 14 wild individuals of P  vera and 35 other genomes from different wild Pistacia species  Integrating genomic and transcriptomic analyses revealed expanded gene families (e g , cytochrome P450 and chitinase) and the jasmonic acid (JA) biosynthetic pathway that are likely involved in stress adaptation  Comparative population genomic analyses revealed that pistachio was domesticated about 8000 years ago, and that likely key genes for domestication are those involved in tree and seed size, which experienced artificial selection 

Species
Bursera simaruba (L ) Sarg  was formerly classified as P  simaruba L 

Ecology
The Pistacia species are vicarious Anacardiaceae with few species outside the Old World, and are mostly more adapted to water shortage and alkaline soil Many plant species are adapted to desert or summer drought typical of Mediterranean climate, so have a high tolerance to saline soil  They grow well in water containing up to 3 0 to 4 0% of soluble salts  They are quite resilient in their ecological requirements, and can survive in temperatures ranging from −10 °C in winter to 45 °C in summer  They prefer places oriented toward the sun and well-drained soil, but grow well in the bottom of ravines  Though very hardy and drought resistant, Pistacia species grow slowly and only begin to bear fruit after about 7-10 years from planting, obtaining full development only after 15-20 years  The fruit ripens in the Mediterranean from August; only female trees have fruit Although some species prefer moderate humidity, they do not grow well in high-humidity conditions  They are susceptible to root rot, molds, and fungi, and parasites attack if they receive too much water and the soil has insufficient drainage  They require a period of drought each year for proper development 
Their leaves are intensely bright green and leathery, with three to nine leaflets  The leaves are alternate, compound, and paripinnate 
The flowers are unisexual, apetalous, and grouped in clusters  The flowers range from purple to green  The fruit is a drupe, generally unpalatable to humans, the size of a pea, and red to brown in color, depending on the degree of maturation  The seeds do not have endosperm 
The seeds are eaten and dispersed by birds, for which they are a valuable resource because of the scarcity of food in some important times of year, as the time of breeding, migration, or the dry season  The commercial species of pistachio has larger fruits and is edible The plants emit a bitter, resinous, or medicative smell, which in some species is very intense and aromatic  Some species develop "galls" that occur in the leaves and leaflets after the bite of insects  Although marred by the presence of galls, they are very vigorous and resistant plants that survive in degraded areas where other species have been eliminated  They multiply by seeds, stolons, and root shoots  Various species hybridize easily between them, and hybrid plants are difficult to identify Some tree species (e g  Pistacia aethiopica, Pistacia atlantica) can exist as small bushes and shrubs due to the extremes of their habitat, adverse conditions, or the excessive consumption by wildlife or livestock that hinders growth Pistacia lentiscus is a very common plant related to P  terebinthus with which it hybridizes  P  terebinthus is more abundant in the mountains and inland in the Iberian Peninsula, and mastic is usually found more frequently in areas where the Mediterranean influence of the sea prevents or moderates frost  Some species with very small ranges cover only one or a group of islands in the Mediterranean  P  terebinthus is also found on the east coast of the Mediterranean, Syria, Lebanon, and Israel, filling the same ecological niche of these species  On the west coast of the Mediterranean, the Canary Islands, and the Middle East, it can be confused with Pistacia atlantica Pistacia species are used as food plants by the larvae (caterpillars) of some species of Lepidoptera including the emperor moth 

Cultivation and uses
Best known as the pistachio, P  vera is a small tree native to Iran, grown for its edible seeds  The seeds of the other species were also eaten in prehistory, but are too small to have commercial value today   Records of Pistacia from preclassical archaeological sites, and mentions in preclassical texts, always refer to one of these other species (often P  terebinthus) P  terebinthus (the terebinth), also a native of Iran, and the western Mediterranean countries, is tapped for turpentine  It is also common in the eastern Mediterranean countries   Because terebinths have the ability to kill certain bacteria, terebinth resin was widely used as a preservative in ancient wine   In the Zagros Mountains of Iran, in one of the earliest examples of winemaking, archaeologists discovered terebinth resin deposits from 5400 to 5000 BC in jars that also contained grape-juice residue P  lentiscus, an evergreen shrub or small tree of the Mediterranean region, supplies a resin called mastic P  chinensis (Chinese pistache), the most frost-tolerant species in the genus, is grown as an ornamental tree, valued for its bright red autumn leaf colour 
Passage 4:
Akbesia
Akbesia is a monotypic moth genus in the family Sphingidae erected by Walter Rothschild and Karl Jordan in 1903  Its only species, Akbesia davidi, the pistacia hawkmoth, was first described by Charles Oberthür in 1884  It is known from southern Turkey, northern Syria, northern Israel, western Jordan, south-eastern Turkey, north-eastern Iraq, south-eastern Georgia, northern Iran, eastern Afghanistan and Iranian Beluchistan  It may also occur across Azerbaijan, the Alborz Mountains of northern Iran, the Zagros Mountains of western and southern Iran, and northern Afghanistan  It often occurs in large numbers at certain sites in rocky, hilly areas supporting scattered trees and shrubs of Quercus, Olea, Ceratonia and Pistacia 
The wingspan is 60–70 mm  Although the adults do not feed, they will drink water if offered  There are two generations per year in Iran with adults on wing in April and from late July to August  In northern Iraq, adults are on from May to June and in August 
The larvae have been recorded feeding on Pistacia atlantica and terebinth (Pistacia terebinthus)  Larvae have also been reared on Cotinus coggygria and Rhus coriaria

Context 2:  Impactors of 10 km across or larger can send debris to Mars through the Earth's atmosphere but these occur rarely, and were more common in the early Solar System 

Proposal to end planetary protection for Mars
In their 2013 paper "The Over Protection of Mars", Alberto Fairén and Dirk Schulze-Makuch suggested that we no longer need to protect Mars, essentially using Zubrin's meteorite transfer argument  This was rebutted in a follow up article "Appropriate Protection of Mars", in Nature by the current and previous planetary protection officers Catharine Conley and John Rummel 

Critique of Category V containment measures
The scientific consensus is that the potential for large-scale effects, either through pathogenesis or ecological disruption, is extremely small  Nevertheless, returned samples from Mars will be treated as potentially biohazardous until scientists can determine that the returned samples are safe  The goal is to reduce the probability of release of a Mars particle to less than one in a million 

Policy proposals
Non-biological contamination
A COSPAR workshop in 2010, looked at issues to do with protecting areas from non biological contamination  They recommended that COSPAR expand its remit to include such issues  Recommendations of the workshop include:

Recommendation 3 COSPAR should add a separate and parallel policy to provide guidance on requirements/best practices for protection of non-living/nonlife-related aspects of Outer Space and celestial bodies
Some ideas proposed include protected special regions, or "Planetary Parks" to keep regions of the Solar System pristine for future scientific investigation, and also for ethical reasons 

Proposed extensions
Astrobiologist Christopher McKay has argued that until we have better understanding of Mars, our explorations should be biologically reversible  For instance if all the microorganisms introduced to Mars so far remain dormant within the spacecraft, they could in principle be removed in the future, leaving Mars completely free of contamination from modern Earth lifeforms 
In the 2010 workshop one of the recommendations for future consideration was to extend the period for contamination prevention to the maximum viable lifetime of dormant microorganisms introduced to the planet 

"'Recommendation 4 ' COSPAR should consider that the appropriate protection of potential indigenous extraterrestrial life shall include avoiding the harmful contamination of any habitable environment —whether extant or foreseeable— within the maximum potential time of viability of any terrestrial organisms (including microbial spores) that may be introduced into that environment by human or robotic activity "
In the case of Europa, a similar idea has been suggested, that it is not enough to keep it free from contamination during our current exploration period  It might be that Europa is of sufficient scientific interest that the human race has a duty to keep it pristine for future generations to study as well  This was the majority view of the 2000 task force examining Europa, though there was a minority view of the same task force that such strong protection measures are not required 

"One consequence of this view is that Europa must be protected from contamination for an open-ended period, until it can be demonstrated that no ocean exists or that no organisms are present  Thus, we need to be concerned that over a time scale on the order of 10 million to 100 million years (an approximate age for the surface of Europa), any contaminating material is likely to be carried into the deep ice crust or into the underlying ocean "
In July 2018, the National Academies of Sciences, Engineering, and Medicine issued a Review and Assessment of Planetary Protection Policy Development Processes  In part, the report urges NASA to create a broad strategic plan that covers both forward and back contamination  The report also expresses concern about private industry missions, for which there is no governmental regulatory authority 

Protecting objects beyond the Solar System
The proposal by the German physicist Claudius Gros, that the technology of the Breakthrough Starshot project may be utilized to establish a biosphere of unicellular organisms on otherwise only transiently habitable exoplanets, has sparked a discussion, to what extent planetary protection should be extended to exoplanets  Gros argues that the extended timescales of
interstellar missions imply that planetary and exoplanetary protection have different ethical groundings

Passage 3:
Transit (astronomy)
In astronomy, a transit (or astronomical transit) is a phenomenon when a celestial body passes directly between a larger body and the observer  As viewed from a particular vantage point, the transiting body appears to move across the face of the larger body, covering a small portion of it The word "transit" refers to cases where the nearer object appears smaller than the more distant object  Cases where the nearer object appears larger and completely hides the more distant object are known as occultations 
However, the probability of seeing a transiting planet is low because it is dependent on the alignment of the three objects in a nearly perfectly straight line  Many parameters of  a planet and its parent star can be determined based on the transit 

In the Solar System
One example of a transit involves the motion of a planet between a terrestrial observer and the Sun  This can happen only with inferior planets, namely Mercury and Venus (see transit of Mercury and transit of Venus)  However, because a transit is dependent on the point of observation, the Earth itself transits the Sun if observed from Mars  In the solar transit by the Moon captured during calibration of the STEREO B spacecraft's ultraviolet imaging, the Moon appears much smaller than it does when seen from Earth, because the spacecraft–Moon separation was several times greater than the Earth–Moon distance 
The term can also be used to describe the motion of a satellite across its parent planet, for instance one of the Galilean satellites (Io, Europa, Ganymede, Callisto) across Jupiter, as seen from Earth 
Although rare, cases where four bodies are lined up do happen  One of these events occurred on 27 June 1586, when Mercury transited the Sun as seen from Venus at the same time as a transit of Mercury from Saturn and a transit of Venus from Saturn 

Notable observations
No missions were planned to coincide with the transit of Earth visible from Mars on 11 May 1984 and the Viking missions had been terminated a year previously  Consequently, the next opportunity to observe such an alignment will be in 2084 
On 21 December 2012, the Cassini–Huygens probe, in orbit around Saturn, observed the planet Venus transiting the Sun On 3 June 2014, the Mars rover Curiosity observed the planet Mercury transiting the Sun, marking the first time a planetary transit has been observed from a celestial body besides Earth 

Mutual planetary transits
In rare cases, one planet can pass in front of another  If the nearer planet appears smaller than the more distant one, the event is called a mutual planetary transit 

Outside the Solar System
Exoplanet Detection

The transit method can be used to discover exoplanets  As a planet eclipses/transits its host star it will block a portion of the light from the star  If the planet transits in-between the star and the observer the change in light can be measured to construct a light curve  Light curves are measured with a charge-coupled device  The light curve of a star can disclose several physical characteristics of the planet and star, such as density  Multiple transit events must be measured to determine the characteristics which tend to occur at regular intervals  Multiple planets orbiting the same host star can cause transit-timing variations (TTV)  TTV is caused by the gravitational forces of all orbiting bodies acting upon each other  The probability of seeing a transit from Earth is low, however  The probability is given by the following equation

  where Rstar and Rplanet are the radius of the star and planet, respectively, and a is the semi-major axis  Because of the low probability of a transit in any specific system, large selections of the sky must be regularly observed in order to see a transit  Hot Jupiters are more likely to be seen because of their larger radius and short semi-major axis  In order to find Earth-sized planets, red dwarf stars are observed because of their small radius  Even though transiting has a low probability it has proven itself to be a good technique for discovering exoplanets 
In recent years, the discovery of extrasolar planets has prompted interest in the possibility of detecting their transits across their own stellar primaries  HD 209458b was the first such transiting planet to be detected 
The transit of celestial objects is one of the few key phenomena used today for the study of exoplanetary systems  Today, transit photometry is the leading form of exoplanet discovery  As an exoplanet moves in front of its host star there is a dimming in the luminosity of the host star that can be measured  Larger planets make the dip in luminosity more noticeable and easier to detect  Followup observations using other methods are often carried out to ensure it is a planet 
There are currently (December 2018) 2345 planets confirmed with Kepler light curves for stellar host 

Contacts
During a transit there are four "contacts", when the circumference of the small circle (small body disk) touches the circumference of the large circle (large body disk) at a single point   Historically, measuring the precise time of each point of contact was one of the most accurate ways to determine the positions of astronomical bodies   The contacts happen in the following order:

First contact: the smaller body is entirely outside the larger body, moving inward ("exterior ingress")
Second contact: the smaller body is entirely inside the larger body, moving further inward ("interior ingress")
Third contact: the smaller body is entirely inside the larger body, moving outward ("interior egress")
Fourth contact: the smaller body is entirely outside the larger body, moving outward ("exterior egress")A fifth named point is that of greatest transit, when the apparent centers of the two bodies are nearest to each other, halfway through the transit 

Missions
Since transit photometry allows for scanning large celestial areas with a simple procedure, it has been the most popular and successful form of finding exoplanets in the past decade and includes many projects, some of which have already been retired, others in use today, and some in progress of being planned and created  The most successful projects include HATNet, KELT, Kepler, and WASP, and some new and developmental stage missions such as TESS, HATPI, and others which can be found among the List of Exoplanet Search Projects 

HATNet
HATNet Project is a set of northern telescopes in Fred Lawrence Whipple Observatory, Arizona and Mauna Kea Observatories, HI, and southern telescopes around the globe, in Africa, Australia, and South America, under the HATSouth branch of the project  These are small aperture telescopes, just like KELT, and look at a wide field which allows them to scan a large area of the sky for possible transiting planets  In addition, their multitude and spread around the world allows for 24/7 observation of the sky so that more short-period transits can be caught A third sub-project, HATPI, is currently under construction and will survey most of the night sky seen from its location in Chile 

KELT
KELT is a terrestrial telescope mission designed to search for transiting systems of planets of magnitude 8<M<10  It began operation in October 2004 in Winer Observatory and has a southern companion telescope added in 2009  KELT North observes "26-degree wide strip of sky that is overhead from North America during the year", while KELT South observes single target areas of the size 26 by 26 degrees  Both telescopes can detect and identify transit events as small as a 1% flux dip, which allows for detection of planetary systems similar to those in our planetary system 

Kepler / K2
The Kepler satellite served the Kepler mission between 7 March 2009 and 11 May 2013, where it observed one part of the sky in search of transiting planets within a 115 square degrees of the sky around the Cygnus, Lyra, and Draco constellations  After that, the satellite continued operating until 15 November 2018, this time changing its field along the ecliptic to a new area roughly every 75 days due to reaction wheel failure 

TESS
TESS was launched on 18 April 2018, and is planned to survey most of the sky by observing it strips defined along the right ascension lines for 27 days each  Each area surveyed is 27 by 90 degrees  Because of the positioning of sections, the area near TESS's rotational axis will be surveyed for up to 1 year, allowing for the identification of planetary systems with longer orbital periods

Passage 4:
Roche limit
In celestial mechanics, the Roche limit, also called Roche radius, is the distance from a celestial body within which a second celestial body, held together only by its own force of gravity, will disintegrate because the first body's tidal forces exceed the second body's self-gravitation  Inside the Roche limit, orbiting material disperses and forms rings, whereas outside the limit, material tends to coalesce  The Roche radius depends on the radius of the first body and on the ratio of the bodies' densities 
The term is named after Édouard Roche (French: [ʁɔʃ], English:  ROSH), the French astronomer who first calculated this theoretical limit in 1848 

Explanation
The Roche limit typically applies to a satellite's disintegrating due to tidal forces induced by its primary, the body around which it orbits  Parts of the satellite that are closer to the primary are attracted more strongly by gravity from the primary than parts that are farther away; this disparity effectively pulls the near and far parts of the satellite apart from each other, and if the disparity (combined with any centrifugal effects due to the object's spin) is larger than the force of gravity holding the satellite together, it can pull the satellite apart  Some real satellites, both natural and artificial, can orbit within their Roche limits because they are held together by forces other than gravitation  Objects resting on the surface of such a satellite would be lifted away by tidal forces  A weaker satellite, such as a comet, could be broken up when it passes within its Roche limit 
Since, within the Roche limit, tidal forces overwhelm the gravitational forces that might otherwise hold the satellite together, no satellite can gravitationally coalesce out of smaller particles within that limit  Indeed, almost all known planetary rings are located within their Roche limit  (Notable exceptions are Saturn's E-Ring and Phoebe ring  These two rings could possibly be remnants from the planet's proto-planetary accretion disc that failed to coalesce into moonlets, or conversely have formed when a moon passed within its Roche limit and broke apart )
The Roche limit is not the only factor that causes comets to break apart  Splitting by thermal stress, internal gas pressure and rotational splitting are other ways for a comet to split under stress 

Determination
The limiting distance to which a satellite can approach without breaking up depends on the rigidity of the satellite  At one extreme, a completely rigid satellite will maintain its shape until tidal forces break it apart  At the other extreme, a highly fluid satellite gradually deforms leading to increased tidal forces, causing the satellite to elongate, further compounding the tidal forces and causing it to break apart more readily 
Most real satellites would lie somewhere between these two extremes, with tensile strength rendering the satellite neither perfectly rigid nor perfectly fluid  For example, a rubble-pile asteroid will behave more like a fluid than a solid rocky one; an icy body will behave quite rigidly at first but become more fluid as tidal heating accumulates and its ices begin to melt 
But note that, as defined above, the Roche limit refers to a body held together solely by the gravitational forces which cause otherwise unconnected particles to coalesce, thus forming the body in question  The Roche limit is also usually calculated for the case of a circular orbit, although it is straightforward to modify the calculation to apply to the case (for example) of a body passing the primary on a parabolic or hyperbolic trajectory 

Rigid satellites
The rigid-body Roche limit is a simplified calculation for a spherical satellite  Irregular shapes such as those of tidal deformation on the body or the primary it orbits are neglected  It is assumed to be in hydrostatic equilibrium  These assumptions, although unrealistic, greatly simplify calculations 
The Roche limit for a rigid spherical satellite is the distance,

This does not depend on the size of the objects, but on the ratio of densities  This is the orbital distance inside of which loose material (e g  regolith) on the surface of the satellite closest to the primary would be pulled away, and likewise material on the side opposite the primary will also go away from, rather than toward, the satellite 

Fluid satellites
A more accurate approach for calculating the Roche limit takes the deformation of the satellite into account  An extreme example would be a tidally locked liquid satellite orbiting a planet, where any force acting upon the satellite would deform it into a prolate spheroid 
The calculation is complex and its result cannot be represented in an exact algebraic formula  Roche himself derived the following approximate solution for the Roche limit:

        ≈

Passage 5:
Ulysses (spacecraft)
Ulysses ( yoo-LISS-eez, UK also  YOO-liss-eez) was a robotic space probe whose primary mission was to orbit the Sun and study it at all latitudes  It was launched in 1990 and made three "fast latitude scans" of the Sun in 1994/1995, 2000/2001, and 2007/2008  In addition, the probe studied several comets  Ulysses was a joint venture of the European Space Agency (ESA) and the United States' National Aeronautics and Space Administration (NASA), under leadership of ESA with participation from Canada's National Research Council  The last day for mission operations on Ulysses was 30 June 2009 To study the Sun at all latitudes, the probe needed to change its orbital inclination and leave the plane of the Solar System  To change the orbital inclination of a spacecraft to about 80° requires a large change in heliocentric velocity, the energy to achieve which far exceeded the capabilities of any launch vehicle  To reach the desired orbit around the Sun, the mission's planners chose a gravity assist maneuver around Jupiter, but this Jupiter encounter meant that Ulysses could not be powered by solar cells  The probe was powered instead by a radioisotope thermoelectric generator (RTG) 
The spacecraft was originally named Odysseus, because of its lengthy and indirect trajectory to study the solar poles  It was renamed Ulysses, the Latin translation of "Odysseus", at ESA's request in honor not only of Homer's mythological hero but also of Dante's character in the Inferno  Ulysses was originally scheduled for launch in May 1986 aboard the Space Shuttle Challenger on STS-61-F  Due to the 28 January 1986 loss of Challenger, the launch of Ulysses was delayed until 6 October 1990 aboard Discovery (mission STS-41) 

Spacecraft
The spacecraft was designed by ESA and built by Dornier Systems, a German aircraft manufacturer  The body was roughly a box, approximately 3 2 m × 3 3 m × 2 1 m (10 5 ft × 10 8 ft × 6 9 ft) in size  The box mounted the 1 65 m (5 ft 5 in) dish antenna and the GPHS-RTG radioisotope thermoelectric generator (RTG) power source  The box was divided into noisy and quiet sections  The noisy section abutted the RTG; the quiet section housed the instrument electronics  Particularly "loud" components, such as the preamps for the radio dipole, were mounted outside the structure entirely, and the box acted as a Faraday cage 
Ulysses was spin-stabilised about its z-axis which roughly coincides with the axis of the dish antenna  The RTG, whip antennas, and instrument boom were placed to stabilize this axis, with the spin rate nominally at 5 rpm  Inside the body was a hydrazine fuel tank  Hydrazine monopropellant was used for course corrections inbound to Jupiter, and later used exclusively to repoint the spin axis (and thus, the antenna) at Earth  The spacecraft was controlled by eight thrusters in two blocks  Thrusters were pulsed in the time domain to perform rotation or translation  Four sun sensors detected orientation  For fine attitude control, the S-band antenna feed was mounted slightly off-axis  This offset feed combined with the spacecraft spin introduced an apparent oscillation to a radio signal transmitted from Earth when received on board the spacecraft  The amplitude and phase of this oscillation were proportional to the orientation of the spin axis relative to the Earth direction  This method of determining the relative orientation is called conical scanning and was used by early radars for automated tracking of targets and was also very common in early infrared guided missiles 
The spacecraft used S-band for uplinked commands and downlinked telemetry, through dual redundant 5-watt transceivers  The spacecraft used X-band for science return (downlink only), using dual 20 watts TWTAs until the failure of the last remaining TWTA in January 2008  Both bands used the dish antenna with prime-focus feeds, unlike the Cassegrain feeds of most other spacecraft dishes 
Dual tape recorders, each of approximately 45-megabit capacity, stored science data between the nominal eight-hour communications sessions during the prime and extended mission phases 
The spacecraft was designed to withstand both the heat of the inner Solar System and the cold at Jupiter's distance  Extensive blanketing and electric heaters protected the probe against the cold temperatures of the outer Solar System 
Multiple computer systems (CPUs/microprocessors/Data Processing Units) are used in several of the scientific instruments, including several radiation-hardened RCA CDP1802 microprocessors  Documented 1802 usage includes dual-redundant 1802s in the COSPIN, and at least one 1802 each in the GRB, HI-SCALE, SWICS, SWOOPS and URAP instruments, with other possible microprocessors incorporated elsewhere Total mass at launch was 371 kg (818 lb), of which 33 5 kg was hydrazine propellant used for attitude control and orbit correction 

Instruments
The twelve different Instruments came from ESA and NASA  The first design was based on two probes, one by NASA and one by ESA, but the probe of NASA was defunded and in the end the instruments of the cancelled probe were mounted on Ulyssses 
Radio/Plasma antennas: Two beryllium copper antennas were unreeled outwards from the body, perpendicular to the RTG and spin axis  Together this dipole spanned 72 meters (236 2 ft)  A third antenna, of hollow beryllium copper, was deployed from the body, along the spin axis opposite the dish  It was a monopole antenna, 7 5 meters (24 6 ft) long  These measured radio waves generated by plasma releases, or the plasma itself as it passed over the spacecraft  This receiver ensemble was sensitive from DC to 1 MHz 
Experiment Boom: A third type of boom, shorter and much more rigid, extended from the last side of the spacecraft, opposite the RTG  This was a hollow carbon-fiber tube, of 50 mm (2 in ) diameter  It can be seen in the photo as the silver rod stowed alongside the body  It carried four types of instruments: a solid-state X-ray instrument, composed of two silicon detectors, to study X-rays from solar flares and Jupiter's aurorae; the Gamma-Ray Burst experiment, consisting of two CsI scintillator crystals with photomultipliers; two different magnetometers, a helium vector magnetometer and a fluxgate magnetometer; and a two-axis magnetic search coil antenna measured AC magnetic fields 
Body-Mounted Instruments: Detectors for electrons, ions, neutral gas, dust, and cosmic rays were mounted on the spacecraft body around the quiet section 
Lastly, the radio communications link could be used to search for gravitational waves (through Doppler shifts) and to probe the Sun's atmosphere through radio occultation  No gravitational waves were detected 
Total instrument mass was 55 kg 
Magnetometer (MAG): MAG measured the magnetic field in the heliosphere  Measurements of Jupiter's magnetic field were also performed 
Solar Wind Plasma Experiment (SWOOPS): detected the solar wind at all solar distances and latitudes and in three dimensions  It measured positive ions and electrons 
Solar Wind Ion Composition Instrument (SWICS): determined composition, temperature and speed of the atoms and ions that comprise the solar wind 
Unified Radio and Plasma Wave Instrument (URAP): picked up radio waves from the Sun and electromagnetic waves generated in the solar wind close to the spacecraft 
Energetic Particle Instrument (EPAC) and GAS: EPAC investigated the energy, fluxes and distribution of energetic particles in the heliosphere  GAS studied the uncharged gases (helium) of interstellar origin 
Low-Energy Ion and Electron Experiment (HI-SCALE): investigated the energy, fluxes and distribution of energetic particles in the heliosphere 
Cosmic Ray and Solar Particle Instrument (COSPIN): investigated the energy, fluxes and distribution of energetic particles and galactic cosmic rays in the heliosphere 
Solar X-ray and Cosmic Gamma-Ray Burst Instrument (GRB): studied cosmic gamma ray bursts and X-rays from solar flares 
Dust Experiment (DUST): Direct measurements of interplanetary and interstellar dust grains to investigate their properties as functions of the distance from the Sun and solar latitude 

Mission
Planning
Until Ulysses, the Sun had only been observed from low solar latitudes  The Earth's orbit defines the ecliptic plane, which differs from the Sun's equatorial plane by only 7 25°  Even spacecraft directly orbiting the Sun do so in planes close to the ecliptic because a direct launch into a high-inclination solar orbit would require a prohibitively large launch vehicle 
Several spacecraft (Mariner 10, Pioneer 11, and Voyagers 1 and 2) had performed gravity assist maneuvers in the 1970s  Those maneuvers were to reach other planets also orbiting close to the ecliptic, so they were mostly in-plane changes  However, gravity assists are not limited to in-plane maneuvers; a suitable flyby of Jupiter could produce a significant plane change  An Out-Of-The-Ecliptic mission (OOE) was thereby proposed  See article Pioneer H 
Originally, two spacecraft were to be built by NASA and ESA, as the International Solar Polar Mission  One would be sent over Jupiter, then under the Sun  The other would fly under Jupiter, then over the Sun  This would provide simultaneous coverage  Due to cutbacks, the U S  spacecraft was cancelled in 1981  One spacecraft was designed, and the project recast as Ulysses, due to the indirect and untried flight path  NASA would provide the Radioisotope Thermoelectric Generator (RTG) and launch services, ESA would build the spacecraft assigned to Astrium GmbH, Friedrichshafen, Germany (formerly Dornier Systems)  The instruments would be split into teams from universities and research institutes in Europe and the United States  This process provided the 12 instruments on board 
The changes delayed launch from February 1983 to May 1986 when it was to be deployed by the Space Shuttle Challenger (boosted by the proposed Centaur G Prime upper stage  However, the Challenger disaster forced a two-and-a-half year stand down of the shuttle fleet, mandated the cancellation of the Centaur-G upper stage, and pushed the launch date to October 1990 

Launch
Ulysses was deployed into low Earth orbit from the Space Shuttle Discovery  From there, it was propelled on a trajectory to Jupiter by a combination of solid rocket motors  This upper stage consisted of a two-stage Boeing IUS (Inertial Upper Stage), plus a McDonnell Douglas PAM-S (Payload Assist Module-Special)  The IUS was inertially stabilised and actively guided during its burn  The PAM-S was unguided and it and Ulysses were spun up to 80 rpm for stability at the start of its burn  On burnout of the PAM-S, the motor and spacecraft stack was yo-yo de-spun (weights deployed at the end of cables) to below 8 rpm prior to separation of the spacecraft  On leaving Earth, the spacecraft became the fastest ever artificially-accelerated spacecraft, and held that title until the New Horizons probe was launched 
On its way to Jupiter, the spacecraft was in an elliptical non-Hohmann transfer orbit  At this time, Ulysses had a low orbital inclination to the ecliptic 

Jupiter swing-by
It arrived at Jupiter on 8 February 1992 for a swing-by maneuver that increased its inclination to the ecliptic by 80 2°  The giant planet's gravity bent the spacecraft's flight path southward and away from the ecliptic plane  This put it into a final orbit around the Sun that would take it past the Sun's north and south poles  The size and shape of the orbit were adjusted to a much smaller degree so that aphelion remained at approximately 5 AU, Jupiter's distance from the Sun, and perihelion was somewhat greater than 1 AU, the Earth's distance from the Sun  The orbital period is approximately six years 

Polar regions of the Sun
Between 1994 and 1995 it explored both the southern and northern polar regions of the Sun, respectively 

Comet C/1996 B2 (Hyakutake)
On 1 May 1996, the spacecraft unexpectedly crossed the ion tail of Comet Hyakutake (C/1996 B2), revealing the tail to be at least 3 8 AU in length 

Comet C/1999 T1 (McNaught–Hartley)
An encounter with a comet tail happened again in 2004  when Ulysses flew through the ion tailings of C/1999 T1 (McNaught-Hartley)  A coronal mass ejection carried the cometary material to Ulysses 

Second Jupiter encounter
Ulysses approached aphelion in 2003/2004 and made further distant observations of Jupiter 

Comet C/2006 P1 (McNaught)
In 2007, Ulysses passed through the tail of comet C/2006 P1 (McNaught)  The results were surprisingly different from its pass through Hyakutake's tail, with the measured solar wind velocity dropping from approximately 700 kilometers per second (1,566,000 mph) to less than 400 kilometers per second (895,000 mph)

ESA's Science Program Committee approved the fourth extension of the Ulysses mission to March 2004  thereby allowing it to operate over the Sun's poles for the third time in 2007 and 2008  After it became clear that the power output from the spacecraft's RTG would be insufficient to operate science instruments and keep the attitude control fuel, hydrazine, from freezing, instrument power sharing was initiated  Up until then, the most important instruments had been kept online constantly, whilst others were deactivated  When the probe neared the Sun, its power-hungry heaters were turned off and all instruments were turned on On 22 February 2008, 17 years and 4 months after the launch of the spacecraft, ESA and NASA announced that the mission operations for Ulysses would likely cease within a few months  On 12 April 2008, NASA announced that the end date will be 1 July 2008 The spacecraft operated successfully for over four times its design life  A component within the last remaining working chain of X-band downlink subsystem failed on 15 January 2008  The other chain in the X-band subsystem had previously failed in 2003 Downlink to Earth resumed on S-band, but the beamwidth of the high gain antenna in the S-band was not as narrow as in the X–band, so that the received downlink signal was much weaker, hence reducing the achievable data rate  As the spacecraft traveled on its outbound trajectory to the orbit of Jupiter, the downlink signal would have eventually fallen below the receiving capability of even the largest antennas (70 meters - 229 7 feet - in diameter) of the Deep Space Network 
Even before the downlink signal was lost due to distance, the hydrazine attitude control fuel on board the spacecraft was considered likely to freeze, as the radioisotope thermal generators (RTGs) failed to generate enough power for the heaters to overcome radiative heat loss into space  Once the hydrazine froze, the spacecraft would no longer be able to maneuver to keep its high gain antenna pointing towards Earth, and the downlink signal would then be lost in a matter of days  The failure of the X-band communications subsystem hastened this, because the coldest part of the fuel pipework was routed over the X-band traveling-wave tube amplifiers, because they generated enough heat during operation to keep the propellant plumbing warm 
The previously announced mission end date of 1 July 2008, came and went but mission operations continued albeit in a reduced capacity  The availability of science data gathering was limited to only when Ulysses was in contact with a ground station due to the deteriorating S-band downlink margin no longer being able to support simultaneous real-time data and tape recorder playback  When the spacecraft was out of contact with a ground station, the S-band transmitter was switched off and the power was diverted to the internal heaters to add to the warming of the hydrazine  On 30 June 2009, ground controllers sent commands to switch to the low gain antennas  This stopped communications with the spacecraft, in combination with previous commands to shut down its transmitter entirely 

Results
During cruise phases, Ulysses provided unique data  As the only spacecraft out of the ecliptic with a gamma-ray instrument, Ulysses was an important part of the InterPlanetary Network (IPN)  The IPN detects gamma ray bursts (GRBs); since gamma rays cannot be focused with mirrors, it was very difficult to locate GRBs with enough accuracy to study them further  Instead, several spacecraft can locate the burst through multilateration  Each spacecraft has a gamma-ray detector, with readouts noted in tiny fractions of a second  By comparing the arrival times of gamma showers with the separations of the spacecraft, a location can be determined, for follow-up with other telescopes  Because gamma rays travel at the speed of light, wide separations are needed  Typically, a determination came from comparing: one of several spacecraft orbiting the Earth, an inner-Solar-system probe (to Mars, Venus, or an asteroid), and Ulysses  When Ulysses crossed the ecliptic twice per orbit, many GRB determinations lost accuracy 
Additional discoveries:
Data provided by Ulysses led to the discovery that the Sun's magnetic field interacts with the Solar System in a more complex fashion than previously assumed 
Data provided by Ulysses led to the discovery that dust coming into the Solar System from deep space was 30 times more abundant than previously expected 
In 2007–2008 data provided by Ulysses led to the determination that the magnetic field emanating from the Sun's poles is much weaker than previously observed 
That the solar wind has "grown progressively weaker during the mission and is currently at its weakest since the start of the Space Age" 

Fate
Ulysses will most likely continue in heliocentric orbit around the Sun indefinitely  However, there is a chance that in one of its re-encounters with Jupiter a close fly-by with one of the Jovian moons would be enough to alter its course and so the probe would enter a hyperbolic trajectory around the Sun and leave the Solar System

Dracula wallisii
Dracula wallisii is a species of orchid belonging to the genus Dracula  The species is found at altitudes of 1,600 to 2,600 m (5,200 to 8,500 ft) in Cordillera Central, Colombia  It is a common species, with large flowers that are often highly variable in form The species was first discovered near Frontino, Antioquia, Colombia by the German plant collector Gustav Wallis in 1871  It was formally described in 1875 by the German orchidologist Heinrich Gustav Reichenbach who named it after Wallis 
Passage 6:
Terebinth
Pistacia terebinthus also called the terebinth  and the turpentine tree, is a deciduous tree species of the genus Pistacia, native to the Mediterranean region from the western regions of Morocco and Portugal to Greece and western and southeastern Turkey  At one time terebinths growing on the eastern shores of the Mediterranean Sea (in Syria, Lebanon and Israel) were regarded as a separate species, Pistacia palaestina, but these are now considered to be a synonym of P  terebinthus 

Description
The terebinth is a deciduous flowering plant belonging to the cashew family, Anacardiaceae; a small tree or large shrub, it grows to 10 m (33 ft) tall  The leaves are compound, 10–20 cm (3 9–7 9 in) long, odd pinnate with five to eleven opposite glossy oval leaflets, the leaflets 2–6 cm (0 79–2 36 in) long and 1–3 cm (0 39–1 18 in) broad  The flowers are reddish-purple, appearing with the new leaves in early spring  The fruit consists of small, globular drupes 5–7 mm (0 20–0 28 in) long, red to black when ripe  All parts of the plant have a strong resinous smell The terebinth is a dioecious tree, i e  it exists as male and female specimens  For a viable population both sexes must be present  The oblong leaf is bright green, leathery, with 10 cm (3 9 in) long or more with three to nine leaflets  Leaves alternate, leathery and compound paripinnate (no terminal leaflet) with three or six deep green leaflets  They are generally larger and rounder than the leaves of the mastic, reminiscent of the leaves of carob tree  The flowers range from purple to green, the fruit is the size of a pea and turns from red to brown, depending on the degree of maturation  The whole plant emits a strong smell: bitter, resinous, or medicinal  In the vegetative period they develop "galls" shaped like a goat's horn (from which the plant gets the name "cornicabra", the common name in Spanish), that occur on the leaves and leaflets which have been bitten by insects  The species propagates by seeds and shoots  Although marred by the presence of galls, it is a very strong and resistant tree which survives in degraded areas where other species have been eliminated  Pistacia terebinthus is related to Pistacia lentiscus, with which it hybridizes frequently in contact zones  Pistacia terebinthus is more abundant in the mountains and inland and the mastic is usually found more frequently in areas where the Mediterranean influence of the sea moderates the climate  The mastic tree does not reach the size of the Pistacia terebinthus, but the hybrids are very difficult to distinguish  The mastic has winged stalks to its leaflets, i e , the stalks are flattened and with side fins, whereas these stems in Pistacia terebinthus are simple  On the west coast of the Mediterranean, Canary Islands and Middle East, P  terebinthus can be confused with P  atlantica 

Habitat
The terebinth prefers relatively moist areas, up to 600 m (2,000 ft) in elevation  It tolerates Mediterranean summer drought and frost more intense than mastic does  The plant is common in the garrigue and maquis  It appears in deciduous oak wood  It has a gray trunk that is very aromatic, and may have multiple trunks or stems when grown as a shrub  Usually reaching 5 m (16 ft) in height, although in rare cases can reach 10 m (33 ft)  P  terebinthus is one of the European species of Anacardiaceae, a family of about 600 mostly tropical species  It can be found to 1,500 m (4,900 ft) above sea level  P  terebinthus is more moisture demanding than the mastic and more resistant to cold  It requires a sunny exposure and average soils, tolerating lime and some salt, often grows near the sea, deep ravines and near salt-lakes and streams 

History
Historian of Mycenae John Chadwick believes that the terebinth is the plant called ki-ta-no in some of the Linear B tablets  He cites the work of a Spanish scholar, J L  Melena, who had found "an ancient lexicon which showed that kritanos was another name for the turpentine tree, and that the Mycenaean spelling could represent a variant form of this word "The Latin name is underlain by the Ancient Greek name τερέβινθος which, in turn, is underlain by a pre-Greek Pelasgian word, marked by the characteristic consonant complex νθ 
Terebinth from Oricum is referred to in Virgil's Aeneid, Book 10, line 136, where Ascanius in battle is compared to "ivory skilfully inlaid in [   ] Orician terebinth" ("inclusum[   ] Oricia terebintho [   ] ebur") 
Terebinth is referred to by Robin Lane Fox in Alexander the Great: "When a Persian king took the throne, he attended Pasargadae, site of King Cyrus's tomb, and dressed in a rough leather uniform to eat a ritual meal of figs, sour milk and leaves of terebinth "The terebinth is mentioned in the Hebrew Scriptures (or Old Testament), where the Hebrew word elah (plural elot) is used, although the word is sometimes translated as 'oak'  It is clear that the translators are uncertain which translation is correct, [   ], yet the two are very different trees to any but the most superficial observation  (The Hebrew word alon means 'oak', and the words may be related ) 
The word terebinth is found in three successive chapters of Genesis (12:6, 13:18, 14:13, 18:1) in reference to the places where Abram (later Abraham) camped called "Terebinths of Mam're the Amorite"  Here, the traditional rendering in English is "oaks of Mamre "
It is also found in Genesis chapter 35, where Jacob commands his family to remove idols that were taken as booty from the battle in Shechem before travelling to Bethel 
Terebinths are also found in Isaiah in possible reference to idolatry associated with the trees, although in the Septuagint and Vulgate the word is translated 'idols', as the plural of el )

For you will be ashamed of the terebinths that you have taken pleasure in 
The best known clear reference to a terebinth (elah) in the Hebrew Scriptures is that of the Valley of Elah or 'Valley of the Terebinth' (עמק האלה), where David fought Goliath (1 Samuel 17:2, 17:19) 
Later in 2 Samuel 18:9 David's rebellious son Absalom is caught in the terebinth tree and is killed by Joab's men, David's army 
At least a few references occur in Judges: chapter 4 (in reference to Heber, the Kenite, of the children of Hobab), chapter 6 (in reference to an angel of the Lord who came to visit Gideon—most versions use 'oak'), and Ch 9 (in reference to the crowning of Abimelech, by the terebinth of the pillar that was in Shechem—again most versions use 'oak')  This reference of Abimelech's crowning by an oak is actually referring to the Palestine oak, closely related to the Kermes oak (Quercus coccifera)  The Hebrew distinguishes the Palestine oak and the terebinth  It is also mentioned in Hosea 4:13 when Hosea is talking about Israel's spiritual adultery by sacrificing to false gods and how to repent and be forgiven in Hosea 14 

Uses
The word "turpentine" was originally used for the exudate of terebinth trees (P  terebinthus and related species such as P  atlantica), now called Chian, Chios, or Cyprian turpentine, and it was later transferred to the crude turpentine (oleoresin) and the oil of turpentine (essential oil) of conifer trees  The word turpentine derives (via Old French and Latin) from the Greek word τερεβινθίνη (terebinthínē), the feminine form (to go with the feminine Greek word for resin) of an adjective τερεβίνθινος (terebínthinos), derived from the Greek noun τερέβινθος (terébinthos), the name for the terebinth tree  However, the main source of the terebinth turpentine is P  atlantica which produces abundant resin instead of P  terebinthus of which the amount of resin is limited The fruits are used in Cyprus for baking of a specialty village bread  In Crete, where the plant is called tsikoudia, it is used to flavor the local variety of pomace brandy, also called tsikoudia  In the Northern Sporades the shoots are used as a vegetable (called tsitsíravla)  The plant is rich in tannins and resinous substances and was used for its aromatic and medicinal properties in classical Greece  A mild sweet scented gum can be produced from the bark, and galls often found on the plant are used for tanning leather  A triterpene has been extracted from these galls  In Turkey, it is known as menengiç or bıttım  A coffee-like beverage, Kurdish coffee or menengiç kahvesi, is made from the roasted fruit, and a soap is made from the oil  Terebinth resin was used as a wine preservative in the entire ancient Near East, as proven by many findings in areas such as the foot of the Zagros Mountains and Middle Bronze Age Galilee

Pistacia aethiopica
Pistacia aethiopica is an African and Arabia coast peninsula species of plant in the family Anacardiaceae  It is a dioecious evergreen shrub or tree of the pistacio genus, growing up to 20 m (66 ft) tall, adapted to the dry environment  It is found in Ethiopia, Kenya, Somalia, Somaliland, Tanzania, Uganda, and Yemen 

Description
It is an evergreen slow-growing tree that emits a  very intense smell: bitter, resinous or similar to medication  The tree reaches 5–15 m tall, and rarely is a shrub, often with multiple stems, the trunk of 0 6 m in diameter, and its bark color is brown-black and fissured  It has glabrous leathery leaves, with a thick cuticle  The leaves are aromatic, 4-16-18 foliolate, and glossy bright green  The leaves have rachis 10 cm long 
The tree is dioecious, with male and female trees producing different sex flowers  Both types of flowers are small and greenish  It grows slowly, becoming 1000 years old 

Ecology
It is found in dry evergreen forest (often with Juniperus and Olea - Euclea) and associated shrubs or wooded grassland, thickets of Buxus, deciduous with Combretum, Acacia and Barkey in soils of limestone, sandstone, or basalt, to an altitude of 900–2550 m  P  aethiopica have many adaptations to aridity, such as an advanced development of palisade tissue and extensive root growth  These adaptive traits allow species to grow in very harsh and dry areas with low rainfall  In the main part of its range in North and East Africa, the species is fairly common because is used for a variety of purposes, including timber, dye, fodder, agriculture and livestock food  An outlying subpopulation in Arabia is restricted to Jebel Iraf on the old North Yemen-South Yemen border  The species is thought to be extinct in Eritrea 
Passage 8:
Pistacia chinensis
Pistacia chinensis, the Chinese pistache (Chinese: 黄連木; pinyin: huángliánmù), is a small to medium-sized tree in the genus Pistacia in the cashew family Anacardiaceae, native to central and western China  This species is planted as a street tree in temperate areas worldwide due to its attractive fruit and autumn foliage 

Description
It is hardy, can withstand harsh conditions and poor quality soils, and grows up to 20 m (66 ft)  The leaves are deciduous, alternate, pinnate, 20–25 cm long, with 10 or 12 leaflets, the terminal leaflet usually absent  The flowers are produced in panicles 15–20 cm (5 9–7 9 in) long at the ends of the branches; it is dioecious, with separate male and female plants The fruit is a small red drupe, turning blue when ripe, containing a single seed 

Taxonomy
Synonyms include: Pistacia formosana Matsumura; P  philippinensis Merrill & Rolfe; Rhus argyi H  Léveillé; R  gummifera H  Léveillé Some botanists merge Pistacia integerrima into this species as the subspecies P  chinensis ssp  integerrima, with the plants considered here then becoming the subspecies P  chinensis ssp  chinensis 

Distribution and habitat
Its native range is on hill and mountain forests on rocky soils at 100–3,600 m (330–11,810 ft) above sea level  It is found in Mainland China (excluding the far north and the far west) and Taiwan 

Ecology
Chinese pistache grows best in full sun, being intolerant of shade; it is the most frost-tolerant species of Pistacia, tolerating temperatures down to about -25 °C, yet it is most highly regarded in warm climates  It is planted for its impressive fall colors, which develop at least as far south as Orlando, Florida  In the low-elevation deserts of Arizona, it is the only tree whose leaves turn scarlet in fall 

Uses
It is a popular choice for street trees in urban settings because it is very drought tolerant and can survive harsh environments  It is also used as an understock for Pistacia vera

Passage 9:
Dracula (plant)
The orchid genus Dracula, abbreviated as Drac in horticultural trade, consists of 118 species native to Mexico, Central America, Colombia, Ecuador and Peru  The name Dracula literally means "little dragon", an allusion to the mythical Count Dracula, a lead character in numerous vampire novels and films  The name was applied to the orchid because of the blood-red color of several of the species, and the strange aspect of the long spurs of the sepals 
The plants were once included in the genus Masdevallia, but became a separate genus in 1978  This genus has been placed in the subtribe Pleurothallidinae 

Description
They are epiphytic and terrestrial species distributed in Central America and the northwest Andes  Almost half the species are found in Ecuador  They prefer shade and rather cool temperatures 
These caespitose orchids grow in tufts from a short rhizome, with a dense pack of stems  They lack pseudobulbs  On each stem grows one large, thin, plicate leaf with a sharply defined midrib  These glabrous, light to dark green  leaves may be spongy, taking over the function of the missing pseudobulb  They are tipped with a mucro (a short tip) 
The flower stalks grow either horizontally from the base of the plant or descend, often for great distances   A few species grow upright flower stalks   The long-tailed terminal flowers are basically triangular  The flowers are borne singly or successively  Three species (sodiroi, decussata/neisseniae, and papillosa) may have up to three simultaneously open flowers on a single stalk  In general, though, if there is more than one flower bud on the raceme, they open up with long intervals  These flowers have a weird aspect, due to the long tails on each sepal  The petals are small and somewhat thickened  Quite commonly, various species of Dracula are known for blooms resembling the faces of primates, a notable example being Dracula simia  However, this likeness to monkeys’ faces seems to be purely a natural coincidence to the primates living in the same forests  In fact, these flowers are pollinated by the common fungus gnat; the bloom’s lip is often quite large (for a Pleurothallid), and from the fungus gnat’s perspective, resembles an irresistible mushroom or fungus  Research by biologists at the University of Oregon indicates that D  lafleurii also possesses a uniquely volatile chemistry, similar to localized species of mushrooms  This mimicry attracts mushroom-associated flies which play a role in pollination  The basal part of the lip (hypochile) is cleft  The terminal part (epichile) is rounded and concave  The margins of the perianth are often fringed  There is a well-developed column with two pollinia
