Many of his works have been lost, including proofs for lemmas cited in the surviving work, some of which are so difficult it would almost stagger the imagination to believe Diophantus really had proofs.
The Tigris and the Euphrates rivers that surround Mesopotamia made irrigation and farming a lot easier and more convenient.
Liu Hui ca China Liu Hui made major improvements to Chang's influential textbook Nine Chapters, making him among the most important of Chinese mathematicians ever. Diamond's error here is to treat natural determinants of plant ecology as somehow determinants of human ecology.
Panini of Shalatula ca BC Gandhara India Panini's great accomplishment was his study of the Sanskrit language, especially in his text Ashtadhyayi.
In evaluating the genius of the ancient Greeks, it is well to remember that their achievements were made without the convenience of modern notation. I'm sure I've overlooked great mathematicians who obviously belong on this list.
His other achievements in optics include improved lens design, an analysis of the camera obscura, Snell's Law, an early explanation for the rainbow, a correct deduction from refraction of atmospheric thickness, and experiments on visual perception. Cuneiform evolved as a simple pictograph.
Archimedes was an astronomer details of his discoveries are lost, but it is likely he knew the Earth rotated around the Sun. Dowe, also of Washington, D. In Mesopotamia, man first harnessed the ox and developed the first plow called ARD. Ancient Greeks, by the way, did not use the unwieldy Roman numerals, but rather used 27 symbols, denoting 1 to 9, 10 to 90, and to Abraham Lincoln abandoned his law studies when he didn't know what "demonstrate" meant and "went home to my father's house [to read Euclid], and stayed there till I could give any proposition in the six books of Euclid at sight.
Since the planets move without friction, their motions offer a pure view of the Laws of Motion; this is one reason that the heliocentric breakthroughs of Copernicus, Kepler and Newton triggered the advances in mathematical physics which led to the Scientific Revolution. In both cases, the sought-after explanation is supposed to be a combination of barriers to diffusion and local environmental obstacles, notably relative absence of potential domesticates.
Pythagoras' successor was apparently Theano herself: Bartlet, who each had a milestone on the road pun intended to successful automobile and bicycle tires.
He neglects diffusion when it is convenient to do so: Both areas may be improved in the future. Hipparchus is called the "Father of Trigonometry"; he developed spherical trigonometry, produced trig tables, and more.
Because a person cannot leave one state and emigrate to another to avoid oppression, since there is only the one state, the Chinese empire. Consequently, the people within local communities are no longer forming close or supportive relationships.
He discusses the evolution of writing, sociopolitical complexity, and technology, devoting most attention unsurprisingly to technology. He is supposed to have invented the Pythagorean Cup, a clever wine goblet which punishes a drinker who greedily fills his cup to the top by then using siphon pressure to drain the cup.
Diamond's answer is, predictably: The most ancient Hindu records did not use the ten digits of Aryabhata, but rather a system similar to that of the ancient Greeks, suggesting that China, and not India, may indeed be the "ultimate" source of the modern decimal system.
