6th century

  • 511Aryabhata, Indian astronomer and mathematician, comes up with concepts of mathematical equations, one of which explains the rotation of the Earth on its axis. This concept is far ahead of its time and he is fairly accurate in his description of it. He also comes up with a lot of other ideas about the Solar System, but many of them are flawed because he considers the Earth to be the center of the universe. Aryabhata is often given credit for coming up with the number zero and using it as a placeholder.source
  • 517Aryabhata compiles his manual of mathematics and astronomy (approximate date).source
  • 550Aryabhata, Indian mathematician-astronomer (b. 476)source
