The Aryabhatiya of Aryabhata. Aryabhatta determined the value of Pi of 3.1416 and the solar year of 365.358 days. He also suggested the heliocentric universe more than 4.200 years before Copernicus, with elliptically orbiting planets and a spherical earth spinning on its axis explaining the motion of the heavens. Aryabhatta is the father of Trigonometry and Algebra, when Europe was in the dark ages. This text is the earliest preserved Indian mathematical and astronomical text bearing the name of an individual author, Aryabhata born 476 A.D, the earliest Indian text to deal specifically the mathematics, and it is the earliest preserved astronomical text from the third or scientific period of Indian astronomy. The only other text which might dispute this last claim is the Suryasiddhanta (translated with elaborate notes by Burgess and Whitney in the sixth volume of the Journal of the American Oriental Society). The old Suryasiddhanta undoubtedly preceded Aryabhata, but the abstracts from it were given early in the sixth century by Varahamiliira in his Pancasiddhantdha show that the preserved text has undergone considerable revision and may be later than Aryabhata. The version of the book presented here is the illustrated English translation published by University of Chicago in 1930. Download the Public Domain e-book here:
The Aryabhatiya of Aryabhata
yoo i think the 4200 years are a miscalculation
“He also suggested the heliocentric universe more than 4.200 years before Copernicus, with elliptically orbiting planets and a spherical earth spinning on its axis explaining the motion of the heavens.”
4th C. Kusumapura AryabhaTTa and the 15th C. Poland-born Nicolas Copernicus could not have a temporal difference of ‘more than 4200 years’ beteween them. This is surely a miscalculation. Both are in AD or CE by Christian chronology.
