The Aryabhatiya of Aryabhata is a book on mathematics and astronomy written by the ancient Indian mathematician and astronomer, Aryabhata. The book is translated and annotated by Walter Eugene Clark. The Aryabhatiya is divided into three sections, each dealing with a different aspect of mathematics and astronomy. The first section covers arithmetic, including the decimal system and place value notation. The second section covers algebra, including equations and the use of zero. The third section covers astronomy, including the motions of the planets and the calculation of eclipses. The book provides insights into the mathematical and astronomical knowledge of ancient India and is an important work in the history of mathematics and astronomy. The translation and annotations by Clark provide additional context and explanation for modern readers.This is a new release of the original 1930 edition.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
