The word sine, the trig function, is derived from Aryabhata's word for that function, and so he established some of the early ideas of trigonometry. He did work in summation. He did significant astronomical work, recognizing the rotation of the earth versus the rotation of the heavens. He had an early concept of gravity. Even some of these notions of the place value system and zero and decimal notation, many of our modern notions of it are traced back to Aryabhata. In other videos on the Islamic Golden Age, when we talk about folks like al-Khwarizmi, a lot of his work was based on what he learned from Aryabhata. Beyond the sciences, and once again, this is just a sample of all that happened during this period.
