The Book Written by Aryabhata
Aryabhata wrote the book Aryabhatiya in 499 AD. It was his treatise on astronomy and mathematics. The book is written in Sanskrit language and discusses various theories of Aryabhata. He discusses how the earth spins on an axis and the different periods of planets in relation to the sun. He also mentions in his work that the shine of the moon is due to the reflection of the sun's light on its surface. In Aryabhatiyam, he also discusses solar and lunar eclipses.
Aryabhatiya is divided into five parts: Gitikapadam, Dasageetika, Ganitapada, Kalakriya and Gola. The book was instrumental in the understanding of calculations of areas and spheres when it was translated to Latin in the 13th century. Aryabhatiya is considered one of the most intelligent works in the field of mathematics and astronomy that shaped modern-day concepts.
