Topic: Compare and contrast the contributions to science and mathematics of Ancient Greece, India, and China. What discoveries have had the most influence on us today? Ancient Greece, China, and India all made important contributions to the fields of science and mathematics. All three of these ancient civilizations made such great contributions that they are still used by many people today. We use these contributions at school, at work and in our daily lives in general. While we don't use the exact inventions they created, we now use modifications of them every day. The discoveries of Greece have more influence on us today than those of India and China because we use these discoveries more often in the fields of astronomy, theoretical sciences, important technology and everyday mathematics. Astronomy is a very important field in science. Ancient Greece, China, and India have all contributed to our ideas and everyday uses of astronomy. Ancient Greece was the most influential because the Indians based most of their astronomy out of Greece. The Greeks created calendars based on the cycle of eclipses, which they called by two different names, Hellenic calendars and lunisolar calendars. Thanks to ancient Greece, we now have calendars that keep us updated every day. The Greeks observed a celestial object passing through the eastern and western morning skies. After a long period of observations, they came to the conclusion that it was a planet and now the planet is well known as Venus. (Sarton, 75) The theories of Plato and Aristotle were an incredible contribution to us today. Both of their theories concerned the behavior and life of planets, such as their theory that the Earth is spherical. (Sartón, 421). Even Ancient Greece...... middle of the sheet......G.
