Fun Facts - ARYABHATTA

**Aryabhatta**is the first of the great astronomers of the classical age of India. He was born in

**Kerala, South India in 476 AD**but later lived in Kusumapura, which his commentator Bhaskara I (629 AD) identifies with pataliputra (modern Patna) in Bihar. His first name “Arya” is hardly a south Indian name while “Bhatt” (or Bhatta) is a typical north Indian name even found today specially among the trader community.

No matter where he could be originated from, people cannot dispute that he resided in Patliputra because he wrote one of his popular “Aryabhatta-siddhanta” but “Aryabhatiya” was much more popular than the former. This is the only work that Aryabhatta do for his survival. His writing consists of mathematical theory and astronomical theory which was viewed to be perfect in modern mathematics. For example, it was written in his theory that when you add 4 to 100 and multiply the result with 8, then add the answer to 62,000 and divide it by 20000, the result will be the same thing as the circumference with diameter twenty thousand. The calculation of 3.1416 is nearly the same with the true value of Pi which is 3.14159. Aryabhatta’s strongest contribution was zero. Another aspect of mathematics that he worked upon is arithemetic, algebra, quadratic equations, trigonometry and sine table.

Aryabhatta was aware that the earth rotates on its axis. The earth rotates round the sun and the moon moves round the earth. He discovered the 9 planets position and related them to their rotation round the sun. Aryabhatta said the light received from planets and the moon is gotten from sun. He also made mention on the eclipse of the sun, moon, day and night, earth contours and the 365 days of the year as the exact length of the year. Aryabhatta also revealed that the earth circumference is 24835 miles when compared to the modern day calculation which is 24900 miles.
Aryabhatta have unusually great intelligence and well skilled in the sense that all his theories has became wonders to some mathematicians of the present age. The Greeks and the Arabs developed some of his works to suit their present demands. Aryabhatta was the first inventor of the earth sphericity and also discovered that earth rotates round the sun. He was the one that created the formula (a + b)2 = a2 + b2 + 2ab. He also created a solution formula of solving the following equations:

1 + 2 + 3 + 4 + 5 + ………… + n = n (n + 1)/2

12 + 22 + 32 + 42 + 52 + …….. + n2 = n (n + 1) (2n + 1)/6

13 + 23 + 33 + 43 + 53 + ……….. n3 = (n (n + 1)/2)2

14 + 24 + 34 + 44 + 54 + ………….. + n4 = (n (n + 1) (2n + 1) (3n2 + 3n – 1))/30
