Some great people and interesting facts



Interesting Facts:

* Baudhayana gave the 'Pythagoras theorem' centuries before the Greeks in 800 BC. 



* Pingala (400 BC) invented the binary number system which is the basic of computer operations. 



* Indian astronomer, Aryabhatta was the first to have propounded the theory that the earth was a sphere in the 5th century. 



* Indian astronomer, Brahmagupta, estimated in the 7th century that the circumference of the earth was 5000 yojanas. A yojana is around 7.2 kms. Calculating on this basis we see that the estimate of 36,000 kms as the earth's circumference comes quite close to the actual circumference known today.
