5729e3631d0469140077964c | Energy | Common energy forms include the kinetic energy of a moving object, the potential energy stored by an object's position in a force field (gravitational, electric or magnetic), the elastic energy stored by stretching solid objects, the chemical energy released when a fuel burns, the radiant energy carried by light, and the thermal energy due to an object's temperature. All of the many forms of energy are convertible to other kinds of energy. In Newtonian physics, there is a universal law of conservation of energy which says that energy can be neither created nor be destroyed; however, it can change from one form to another. | In Newtonian physics, there is a universal law that says energy can be neither created nor what? | {

5730b9a8396df919000962e3 | Sumer | As is known from the "Sumerian Farmer's Almanac", after the flood season and after the Spring Equinox and the Akitu or New Year Festival, using the canals, farmers would flood their fields and then drain the water. Next they made oxen stomp the ground and kill weeds. They then dragged the fields with pickaxes. After drying, they plowed, harrowed, and raked the ground three times, and pulverized it with a mattock, before planting seed. Unfortunately the high evaporation rate resulted in a gradual increase in the salinity of the fields. By the Ur III period, farmers had switched from wheat to the more salt-tolerant barley as their principal crop. | When would farmers flood their fields? | {

5727a9fa4b864d19001639e6 | Cubism | A significant modification of Cubism between 1914 and 1916 was signaled by a shift towards a strong emphasis on large overlapping geometric planes and flat surface activity. This grouping of styles of painting and sculpture, especially significant between 1917 and 1920, was practiced by several artists; particularly those under contract with the art dealer and collector Léonce Rosenberg. The tightening of the compositions, the clarity and sense of order reflected in these works, led to its being referred to by the critic Maurice Raynal (fr) as 'crystal' Cubism. Considerations manifested by Cubists prior to the outset of World War I—such as the fourth dimension, dynamism of modern life, the occult, and Henri Bergson's concept of duration—had now been vacated, replaced by a purely formal frame of reference. | What was the first time period that a significant change began to happen in Cubism? | {

56e0e8b47aa994140058e79d | Space_Race | On January 31, 1958, nearly four months after the launch of Sputnik 1, von Braun and the United States successfully launched its first satellite on a four-stage Juno I rocket derived from the US Army's Redstone missile, at Cape Canaveral. The satellite Explorer 1 was 30.8 pounds (14.0 kg) in mass. It carried a micrometeorite gauge and a Geiger-Müller tube. It passed in and out of the Earth-encompassing radiation belt with its 194-by-1,368-nautical-mile (360 by 2,534 km) orbit, therefore saturating the tube's capacity and proving what Dr. James Van Allen, a space scientist at the University of Iowa, had theorized. The belt, named the Van Allen radiation belt, is a doughnut-shaped zone of high-level radiation intensity around the Earth above the magnetic equator. Van Allen was also the man who designed and built the satellite instrumentation of Explorer 1. The satellite actually measured three phenomena: cosmic ray and radiation levels, the temperature in the spacecraft, and the frequency of collisions with micrometeorites. The satellite had no memory for data storage, therefore it had to transmit continuously. Two months later in March 1958, a second satellite was sent into orbit with augmented cosmic ray instruments. | The Explorer gathered what 3 measurements? | {

As news of the lectures' lucidity grew, professional physicists and graduate students began to drop in to listen. Co-authors Robert B. Leighton and Matthew Sands, colleagues of Feynman, edited and illustrated them into book form. The work has endured and is useful to this day. They were edited and supplemented in 2005 with "Feynman's Tips on Physics: A Problem-Solving Supplement to the Feynman Lectures on Physics" by Michael Gottlieb and Ralph Leighton (Robert Leighton's son), with support from Kip Thorne and other physicists. | Where do the Feynman Lectures on Physics pull information from? | {

They favor biologically-based theories, which point to genetic factors, the early uterine environment, both, or the inclusion of genetic and social factors. There is no substantive evidence which suggests parenting or early childhood experiences play a role when it comes to sexual orientation.

In 1953, the Queen and her husband embarked on a seven-month round-the-world tour, visiting 13 countries and covering more than 40,000 miles by land, sea and air. She became the first reigning monarch of Australia and New Zealand to visit those nations. During the tour, crowds were immense; three-quarters of the population of Australia were estimated to have seen her.

When a massive slave revolt planned by Denmark Vesey, a free black, was revealed in May 1822, whites reacted with intense fear, as they were well aware of the violent retribution of slaves against whites during the Haitian Revolution. Soon after, Vesey was tried and executed, hanged in early July with five slaves. Another 28 slaves were later hanged. Later, the state legislature passed laws requiring individual legislative approval for manumission (the freeing of a slave) and regulating activities of free blacks and slaves. | How was Vesey executed in 1822? | {

572f7b31b2c2fd140056817e | Modern_history | In North America, especially the first half of this period, people experienced considerable prosperity in the Roaring Twenties. The social and societal upheaval known as the Roaring Twenties began in North America and spread to Europe in the aftermath of World War I. The Roaring Twenties, often called "The Jazz Age", saw an exposition of social, artistic, and cultural dynamism. 'Normalcy' returned to politics, jazz music blossomed, the flapper redefined modern womanhood, Art Deco peaked. The spirit of the Roaring Twenties was marked by a general feeling of discontinuity associated with modernity, a break with traditions. Everything seemed to be feasible through modern technology. New technologies, especially automobiles, movies and radio proliferated 'modernity' to a large part of the population. The 1920s saw the general favor of practicality, in architecture as well as in daily life. The 1920s was further distinguished by several inventions and discoveries, extensive industrial growth and the rise in consumer demand and aspirations, and significant changes in lifestyle. | Where did the "Roaring Twenties" begin? | {

Empress Joséphine had still not given birth to a child from Napoleon, who became worried about the future of his empire following his death. Desperate for a legitimate heir, Napoleon divorced Joséphine in January 1810 and started looking for a new wife. Hoping to cement the recent alliance with Austria through a family connection, Napoleon married the Archduchess Marie Louise, who was 18 years old at the time. On 20 March 1811, Marie Louise gave birth to a baby boy, whom Napoleon made heir apparent and bestowed the title of King of Rome.

57325526e17f3d1400422890 | Protestantism | In the Middle Ages, the Church and the worldly authorities were closely related. Martin Luther separated the religious and the worldly realms in principle (doctrine of the two kingdoms). The believers were obliged to use reason to govern the worldly sphere in an orderly and peaceful way. Luther's doctrine of the priesthood of all believers upgraded the role of laymen in the church considerably. The members of a congregation had the right to elect a minister and, if necessary, to vote for his dismissal (Treatise On the right and authority of a Christian assembly or congregation to judge all doctrines and to call, install and dismiss teachers, as testified in Scripture; 1523). Calvin strengthened this basically democratic approach by including elected laymen (church elders, presbyters) in his representative church government. The Huguenots added regional synods and a national synod, whose members were elected by the congregations, to Calvin's system of church self-government.

57272b9d708984140094da9a | Late_Middle_Ages | The Bulgarian Empire was in decline by the 14th century, and the ascendancy of Serbia was marked by the Serbian victory over the Bulgarians in the Battle of Velbazhd in 1330. By 1346, the Serbian king Stefan Dušan had been proclaimed emperor. Yet Serbian dominance was short-lived; the Serbian army led by the Lazar Hrebljevanovic was defeated by the Ottomans at the Battle of Kosovo in 1389, where most of the Serbian nobility was killed and the south of the country came under Ottoman occupation, as much of southern Bulgaria had become Ottoman territory in 1371. Northern remnants of Bulgaria were finally conquered by 1396, Serbia fell in 1459, Bosnia in 1463, and Albania was finally subordinated in 1479 only a few years after the death of Skanderbeg.

571d0d42dd7acb1400e4c1f8 | Pharmaceutical_industry | In 1952 researchers at Ciba discovered the first orally available vasodilator, hydralazine. A major shortcoming of hydralazine monotherapy was that it lost its effectiveness over time (tachyphylaxis). In the mid-1950s Karl H. Beyer, James M. Sprague, John E. Baer, and Frederick C.

56d08581234ae51400d9c33c | Buddhism | Gautama first went to study with famous religious teachers of the day, and mastered the meditative attainments they taught. But he found that they did not provide a permanent end to suffering, so he continued his quest. He next attempted an extreme asceticism, which was a religious pursuit common among the śramaṇas, a religious culture distinct from the Vedic one. Gautama underwent prolonged fasting, breath-holding, and exposure to pain. He almost starved himself to death in the process. He realized that he had taken this kind of practice to its limit, and had not put an end to suffering. So in a pivotal moment he accepted milk and rice from a village girl and changed his approach. He devoted himself to anapanasati meditation, through which he discovered what Buddhists call the Middle Way (Skt. madhyamā-pratipad): a path of moderation between the extremes of self-indulgence and self-mortification.[web 2][web 3] | What are some of the practices Gautama underwent on his quest? | {

This law contains two provisions criminalizing two sorts of activity. The first, 18 U.S.C. § 1831(a), criminalizes the theft of trade secrets to benefit foreign powers. The second, 18 U.S.C. § 1832, criminalizes their theft for commercial or economic purposes. (The statutory penalties are different for the two offenses.)

Jacob's twelve sons became the ancestors of the Israelites, also known as the Twelve Tribes of Israel or Children of Israel. Jacob and his sons had lived in Canaan but were forced by famine to go into Egypt for four generations, lasting 430 years, until Moses, a great-great grandson of Jacob, led the Israelites back into Canaan during the "Exodus".

At the cloud tops, the prevailing winds range in speed from 400 m/s along the equator to 250 m/s at the poles. Most of the winds on Neptune move in a direction opposite the planet's rotation. The general pattern of winds showed prograde rotation at high latitudes vs. retrograde rotation at lower latitudes.

In turn, Gaddafi played up his commercial relationship with the Soviets, visiting Moscow again in April 1981 and 1985, and threatening to join the Warsaw Pact. The Soviets were nevertheless cautious of Gaddafi, seeing him as an unpredictable extremist. Beginning military exercises in the Gulf of Sirte – an area of sea that Libya claimed as a part of its territorial waters – in August 1981 the U.S. shot down two Libyan Su-22 planes monitoring them. Closing down Libya's embassy in Washington, D.C., Reagan advised U.S. companies operating in the country to reduce the number of American personnel stationed there. In March 1982, the U.S. implemented an embargo of Libyan oil, and in January 1986 ordered all U.S. companies to cease operating in the country, although several hundred workers remained.

It involves, or is related to, biological classification, scientific taxonomy and phylogenetics. Biological classification is the method by which botanists group organisms into categories such as genera or species. Biological classification is a form of scientific taxonomy. Modern taxonomy is rooted in the work of Carl Linnaeus, who grouped species according to shared physical characteristics. These groupings have since been revised to align better with the Darwinian principle of common descent – grouping organisms by ancestry rather than superficial characteristics. While scientists do not always agree on how to classify organisms, molecular phylogenetics, which uses DNA sequences as data, has driven many recent revisions along evolutionary lines and is likely to continue to do so. The dominant classification system is called Linnaean taxonomy. It includes ranks and binomial nomenclature. The nomenclature of botanical organisms is codified in the International Code of Nomenclature for algae, fungi, and plants (ICN) and administered by the International Botanical Congress. | How did Linnaeus group organisms? | {

570a34484103511400d595c8 | Beer | Cask-conditioned ales (or cask ales) are unfiltered and unpasteurised beers. These beers are termed "real ale" by the CAMRA organisation. Typically, when a cask arrives in a pub, it is placed horizontally on a frame called a "stillage" which is designed to hold it steady and at the right angle, and then allowed to cool to cellar temperature (typically between 11–13 °C or 52–55 °F), before being tapped and vented—a tap is driven through a (usually rubber) bung at the bottom of one end, and a hard spile or other implement is used to open a hole in the side of the cask, which is now uppermost. The act of stillaging and then venting a beer in this manner typically disturbs all the sediment, so it must be left for a suitable period to "drop" (clear) again, as well as to fully condition—this period can take anywhere from several hours to several days. At this point the beer is ready to sell, either being pulled through a beer line with a hand pump, or simply being "gravity-fed" directly into the glass. | What temperature are cask ales stored at before being tapped? | {

It was faster, able to catch the bombers and its configuration of four machine guns in a turret could (much like German night fighters in 1943–1945 with Schräge Musik) engage the unsuspecting German bomber from beneath. Attacks from below offered a larger target, compared to attacking tail-on, as well as a better chance of not being seen by the bomber (so less chance of evasion), as well as greater likelihood of detonating its bombload.

572751dc5951b619008f884d | Affirmative_action_in_the_United_States | Terry Eastland, the author who wrote From Ending Affirmative Action: The Case for Colorblind Justice states, "Most arguments for affirmative action fall into two categories: remedying past discrimination and promoting diversity". Eastland believes that the founders of affirmative action did not anticipate how the benefits of affirmative action would go to those who did not need it, mostly middle class minorities. Additionally, she argues that affirmative action carries with it a stigma that can create feelings of self-doubt and entitlement in minorities. Eastland believes that affirmative action is a great risk that only sometimes pays off, and that without it we would be able to compete more freely with one another. Libertarian economist Thomas Sowell identified what he says are negative results of affirmative action in his book, Affirmative Action Around the World: An Empirical Study. Sowell writes that affirmative action policies encourage non-preferred groups to designate themselves as members of preferred groups [i.e., primary beneficiaries of affirmative action] to take advantage of group preference policies; that they tend to benefit primarily the most fortunate among the preferred group (e.g., upper and middle class blacks), often to the detriment of the least fortunate among the non-preferred groups (e.g., poor white or Asian); that they reduce the incentives of both the preferred and non-preferred to perform at their best – the former because doing so is unnecessary and the latter because it can prove futile – thereby resulting in net losses for society as a whole; and that they engender animosity toward preferred groups as well.:115–147 | What argument does Sowell make in his claim that non - preferred minorities have less incentive to perform at their best? | {

571b0c1032177014007ea022 | Asphalt | The word asphalt is derived from the late Middle English, in turn from French asphalte, based on Late Latin asphalton, asphaltum, which is the latinisation of the Greek ἄσφαλτος (ásphaltos, ásphalton), a word meaning "asphalt/bitumen/pitch", which perhaps derives from ἀ-, "without" and σφάλλω (sfallō), "make fall". Note that in French, the term asphalte is used for naturally occurring bitumen-soaked limestone deposits, and for specialised manufactured products with fewer voids or greater bitumen content than the "asphaltic concrete" used to pave roads. It is a significant fact that the first use of asphalt by the ancients was in the nature of a cement for securing or joining together various objects, and it thus seems likely that the name itself was expressive of this application. Specifically Herodotus mentioned that bitumen was brought to Babylon to build its gigantic fortification wall. From the Greek, the word passed into late Latin, and thence into French (asphalte) and English ("asphaltum" and "asphalt"). | What are the meanings of the Greek word for asphalt? | {

571a993510f8ca140030518d | Ashkenazi_Jews | A 2010 study on Jewish ancestry by Atzmon-Ostrer et al. stated "Two major groups were identified by principal component, phylogenetic, and identity by descent (IBD) analysis: Middle Eastern Jews and European/Syrian Jews. The IBD segment sharing and the proximity of European Jews to each other and to southern European populations suggested similar origins for European Jewry and refuted large-scale genetic contributions of Central and Eastern European and Slavic populations to the formation of Ashkenazi Jewry", as both groups – the Middle Eastern Jews and European/Syrian Jews – shared common ancestors in the Middle East about 2500 years ago. The study examines genetic markers spread across the entire genome and shows that the Jewish groups (Ashkenazi and non Ashkenazi) share large swaths of DNA, indicating close relationships and that each of the Jewish groups in the study (Iranian, Iraqi, Syrian, Italian, Turkish, Greek and Ashkenazi) has its own genetic signature but is more closely related to the other Jewish groups than to their fellow non-Jewish countrymen. Atzmon's team found that the SNP markers in genetic segments of 3 million DNA letters or longer were 10 times more likely to be identical among Jews than non-Jews. Results of the analysis also tally with biblical accounts of the fate of the Jews. The study also found that with respect to non-Jewish European groups, the population most closely related to Ashkenazi Jews are modern-day Italians. The study speculated that the genetic-similarity between Ashkenazi Jews and Italians may be due to inter-marriage and conversions in the time of the Roman Empire. It was also found that any two Ashkenazi Jewish participants in the study shared about as much DNA as fourth or fifth cousins. | In a 2010 study, which two groups were identified by principal component, phylogenetic, and identity by descent analysis? | {

Many of the popes prior to 750 were more concerned with Byzantine affairs and eastern theological controversies. The register, or archived copies of the letters, of Pope Gregory the Great (pope 590–604) survived, and of those more than 850 letters, the vast majority were concerned with affairs in Italy or Constantinople. The only part of Western Europe where the papacy had influence was Britain, where Gregory had sent the Gregorian mission in 597 to convert the Anglo-Saxons to Christianity. Irish missionaries were most active in Western Europe between the 5th and the 7th centuries, going first to England and Scotland and then on to the continent.

The Irish left the Big East for the ACC during a prolonged period of instability in the Big East; while they maintain their football independence, they have committed to play five games per season against ACC opponents. In ice hockey, the Irish were forced to find a new conference home after the Big Ten Conference's decision to add the sport in 2013–14 led to a cascade of conference moves that culminated in the dissolution of the school's former hockey home, the Central Collegiate Hockey Association, after the 2012–13 season. Notre Dame moved its hockey team to Hockey East. After Notre Dame joined the ACC, the conference announced it would add fencing as a sponsored sport beginning in the 2014–15 school year.

The official colors of Notre Dame are Navy Blue and Gold Rush which are worn in competition by its athletic teams. In addition, the color green is often worn because of the Fighting Irish nickname. The Notre Dame Leprechaun is the mascot of the athletic teams. Created by Theodore W.

In this process, uranium hexafluoride is repeatedly diffused through a silver-zinc membrane, and the different isotopes of uranium are separated by diffusion rate (since uranium 238 is heavier it diffuses slightly slower than uranium-235). The molecular laser isotope separation method employs a laser beam of precise energy to sever the bond between uranium-235 and fluorine. This leaves uranium-238 bonded to fluorine and allows uranium-235 metal to precipitate from the solution. An alternative laser method of enrichment is known as atomic vapor laser isotope separation (AVLIS) and employs visible tunable lasers such as dye lasers. Another method used is liquid thermal diffusion. | In the gaseous diffusion process, what is diffused through a silver-zinc membrane? | {

57319e32e99e3014001e618a | University | A national university is generally a university created or run by a national state but at the same time represents a state autonomic institution which functions as a completely independent body inside of the same state. Some national universities are closely associated with national cultural or political aspirations, for instance the National University of Ireland in the early days of Irish independence collected a large amount of information on the Irish language and Irish culture. Reforms in Argentina were the result of the University Revolution of 1918 and its posterior reforms by incorporating values that sought for a more equal and laic higher education system. | In what year did Argentina's University Revolution occur? | {

56f76011a6d7ea1400e1721a | Treaty | Articles 46–53 of the Vienna Convention on the Law of Treaties set out the only ways that treaties can be invalidated—considered unenforceable and void under international law. A treaty will be invalidated due to either the circumstances by which a state party joined the treaty, or due to the content of the treaty itself. Invalidation is separate from withdrawal, suspension, or termination (addressed above), which all involve an alteration in the consent of the parties of a previously valid treaty rather than the invalidation of that consent in the first place. | Which processes simply alter the consent given by parties to a previously valid treaty rather than invalidating the consent completely? | {

57277d935951b619008f8b43 | Turner_Classic_Movies | TCM's film content has remained mostly uncut and uncolorized (with films natively filmed or post-produced in the format being those only ones presented in color), depending upon the original content of movies, particularly movies released after the 1968 implementation of the Motion Picture Association of America's ratings system and the concurrent disestablishment of the Motion Picture Production Code. Because of this, TCM is formatted similarly to a premium channel with certain films – particularly those made from the 1960s onward – sometimes featuring nudity, sexual content, violence and/or strong profanity; the network also features rating bumpers prior to the start of a program (most programs on TCM, especially films, are rated for content using the TV Parental Guidelines, in lieu of the MPAA's rating system). | In what year did the Motion Picture Association of America introduce its rating system? | {
