Mahan KhagolvidGanitagya Aryabhat: The Great AstronomerMathematician, Genius of Ancient Indian Mathematics and Astronomy | Ess

Aryabhata gave the ratio of the circumference of a circle to its diameter as 3.1416, a fairly accurate value. He also called it approximate.Sometimes, even correct scientific theories remain unaccepted for centuries. The scientists who proposed them remain anonymous and neglected for long periods. The history of science contains numerous examples of this. One such example is Aryabhata and his revolutionary work in mathematics and astrology.Aryabhata was one of the greatest mathematicians and astronomers of ancient India. Western scholars also acknowledge him as a leading scientist of his time (5th-6th centuries AD). Aryabhata is the first Indian to present the theory of Earths rotation. He provided scientific explanations for solar and lunar eclipses. Aryabhata gave the ratio of the circumference of a circle to its diameter as 3.1416, a fairly accurate value. He also called this an approximate value.Although the foundations of trigonometry were laid by Greek mathematicians, Western scholars also acknowledge that the trigonometry taught worldwide today is based on Aryabhatas method.Aryabhatiya is the first treatise on Indian mathematics and astrology, presenting numbers in a decimal place value system with zero. Aryabhata gave birth to a new alphabetic system by using the alphabet.This book is a revolutionary document of the life and work of Aryabhata, who enjoyed a highly respected position among astronomers due to his scholarship.
