Atlantic Ocean

The oldest known mentions of an "Atlantic" sea come from Stesichorus around mid-sixth century BC (Sch. A. R. 1. 211):[6] Atlantikoi pelágei (Greek: Ἀτλαντικῷ πελάγει; English: 'the Atlantic sea'; etym. 'Sea of Atlantis') and in The Histories of Herodotus around 450 BC (Hdt. 1.202.4): Atlantis thalassa (Greek: Ἀτλαντὶς θάλασσα; English: 'Sea of Atlantis' or 'the Atlantis sea'[7]) where the name refers to "the sea beyond the pillars of Heracles" which is said to be part of the sea that surrounds all land.[8]  Thus, on one hand, the name refers to Atlas, the Titan in Greek mythology, who supported the heavens and who later appeared as a frontispiece in Medieval maps and also lent his name to modern atlases.[9]  On the other hand, to early Greek sailors and in Ancient Greek mythological literature such as the Iliad and the Odyssey, this all-encompassing ocean was instead known as Oceanus, the gigantic river that encircled the world; in contrast to the enclosed seas well known to the Greeks: the Mediterranean and the Black Sea.[10] In contrast, the term "Atlantic" originally referred specifically to the Atlas Mountains in Morocco and the sea off the Strait of Gibraltar and the North African coast.[9] The Greek word thalassa has been reused by scientists for the huge Panthalassa ocean that surrounded the supercontinent Pangaea hundreds of millions of years ago.

Raphael

According to Vasari, his father placed him in the workshop of the Umbrian master Pietro Perugino as an apprentice "despite the tears of his mother". The evidence of an apprenticeship comes only from Vasari and another source,[14] and has been disputed—eight was very early for an apprenticeship to begin. An alternative theory is that he received at least some training from Timoteo Viti, who acted as court painter in Urbino from 1495.[15] Most modern historians agree that Raphael at least worked as an assistant to Perugino from around 1500; the influence of Perugino on Raphael's early work is very clear: "probably no other pupil of genius has ever absorbed so much of his master's teaching as Raphael did", according to Wölfflin.[16] Vasari wrote that it was impossible to distinguish between their hands at this period, but many modern art historians claim to do better and detect his hand in specific areas of works by Perugino or his workshop. Apart from stylistic closeness, their techniques are very similar as well, for example having paint applied thickly, using an oil varnish medium, in shadows and darker garments, but very thinly on flesh areas. An excess of resin in the varnish often causes cracking of areas of paint in the works of both masters.[17] The Perugino workshop was active in both Perugia and Florence, perhaps maintaining two permanent branches.[18] Raphael is described as a "master", that is to say fully trained, in December 1500.[19]

Question: Who was Raphael's teacher?
Answer: Pietro Perugino
Wilhelm Wundt

Wilhelm Maximilian Wundt (/vʊnt/; German:[vʊnt]; 16 August 1832 – 31 August 1920) was a German physician, physiologist, philosopher, and professor, known today as one of the founding figures of modern psychology. Wundt, who noted psychology as a science apart from philosophy and biology, was the first person ever to call himself a psychologist.[2] He is widely regarded as the "father of experimental psychology".[3][4] In 1879, Wundt founded the first formal laboratory for psychological research at the University of Leipzig. This marked psychology as an independent field of study.[5] By creating this laboratory he was able to establish psychology as a separate science from other disciplines. He also formed the first academic journal for psychological research, Philosophische Studien (from 1881 to 1902), set up to publish the Institute's research.[6]

Question: Who is considered the founder of modern psychology?

Counter-IED efforts

Counter-IED efforts are done primarily by military and law enforcement (led by intelligence efforts) with the assistance of the diplomatic and financial communities. It involves a comprehensive approach of countering the threat networks that employ improvised explosive devices (IEDs), defeating the devices themselves, and training others. Counter-IED, or C-IED, is usually part of a broader counter-terrorism, counter-insurgency, or law enforcement effort. Because IEDs are a subset of a number of forms of asymmetric warfare used by insurgents and terrorists, C-IED activities are principally against adversaries and not only against IEDs. C-IED treats the IED as a systemic problem and aims to defeat the IED System.

Question: How does Counter-IED work?
Answer: It involves a comprehensive approach of countering the threat networks that employ improvised explosive devices (IEDs), defeating the devices themselves, and training others
Transistor

The transistor is the fundamental building block of modern electronic devices, and is ubiquitous in modern electronic systems. Julius Edgar Lilienfeld patented a field-effect transistor in 1926[1] but it was not possible to actually construct a working device at that time. The first practically implemented device was  a point-contact transistor invented in 1947 by American physicists John Bardeen, Walter Brattain, and William Shockley. The transistor revolutionized the field of electronics, and paved the way for smaller and cheaper radios, calculators, and computers, among other things. The transistor is on the list of IEEE milestones in electronics,[2] and Bardeen, Brattain, and Shockley shared the 1956 Nobel Prize in Physics for their achievement.[3]

Question: Who developed the transistor?
Answer: John Bardeen, Walter Brattain, and William Shockley

Fatty acid

In chemistry, particularly in biochemistry, a fatty acid is a carboxylic acid with a long aliphatic chain, which is either saturated or unsaturated. Most naturally occurring fatty acids have an unbranched chain of an even number of carbon atoms, from 4 to 28.[1] Fatty acids are usually not found in organisms, but instead as three main classes of esters: triglycerides, phospholipids, and cholesterol esters. In any of these forms, fatty acids are both important dietary sources of fuel for animals and they are important structural components for cells.

Transistor radio

A transistor radio is a small portable radio receiver that uses transistor-based circuitry.  Following their development in 1954, made possible by the invention of the transistor in 1947, they became the most popular electronic communication device in history, with billions[1] manufactured during the 1960s and 1970s. Their pocket size sparked a change in popular music listening habits, allowing people to listen to music anywhere they went. Beginning in the 1980s, however, cheap AM transistor radios were superseded by devices with higher audio quality such as portable CD players, personal audio players, boomboxes, and (eventually) smartphones,[2] some of which contain radios themselves.[3]

Dissection

Human dissections were carried out by the Greek physicians Herophilus of Chalcedon and Erasistratus of Chios in the early part of the third century BC.[7] During this period, the first exploration into full human anatomy was performed rather than a base knowledge gained from 'problem-solution' delving.[8] While there was a deep taboo in Greek culture concerning human dissection, there was at the time a strong push by the Ptolemaic government to build Alexandria into a hub of scientific study.[8] For a time, Roman law forbade dissection and autopsy of the human body,[9] so physicians had to use other cadavers. Galen, for example, dissected the Barbary macaque and other primates, assuming their anatomy was basically the same as that of humans.[10][11][12]

Question: Who first performed human dissection?
Answer: Herophilus of Chalcedon and Erasistratus of Chios
