Aryabhatta : The Indian Mathematician

Name :  Aryabhatta

Known as : Great Mathematician and astronomer

Birth : 476 A.D.

Invention : Algebra

ARYABHATTA, as written by the Arabs, ARJABAHR, a celebrated Hindu mathematician, and the earliest known author on Algebra, is now generally believed to have lived about the beginning of our era. Nothing, however, has yet appeared that can give us the slightest information as to the place of his birth, or the time when he lived; nor is there, as far as we know, any tradition or record extent from which we can collect any of the circumstances of his life;

he wrote his famous treatise the “Aryabhatta-siddhanta” but more famously the “Aryabhatiya“, the only work to have survived. It contains mathematical and astronomical theories that have been revealed to be quite accurate in modern mathematics. For instance he wrote that if 4 is added to 100 and then multiplied by 8 then added to 62,000 then divided by 20,000 the answer will be equal to the circumference of a circle of diameter twenty thousand. This calculates to 3.1416 close to the actual value Pi (3.14159). But his greatest contribution has to be zero. His other works include algebra, arithmetic, trigonometry, quadratic equations and the sine table.

He already knew that the earth spins on its axis, the earth moves round the sun and the moon rotates round the earth. He talks about the position of the planets in relation to its movement around the sun. He refers to the light of the planets and the moon as reflection from the sun. He goes as far as to explain the eclipse of the moon and the sun, day and night, the contours of the earth, the length of the year exactly as 365 days.

He even computed the circumference of the earth as 24835 miles which is close to modern day calculation of 24900 miles.

This remarkable man was a genius and continues to baffle many mathematicians of today. His works was then later adopted by the Greeks and then the Arabs.
