   You will be surprised to know that a lot of scientific knowledge was evolved in ancient India, so many years ago. During this period Science and Mathematics were highly developed and Ancient Indians had contributed immensely. Ayurveda is the indigenous system of medicine that was developed in Ancient Period. Even the science of Yoga was also developed as an allied science of Ayurveda. In this article we will see the contributions of some scientists of ancient India. 1. Aryabhatta He was a fifth century mathematician, astronomer, astrologer and physicist. - At the age of 23, he wrote Aryabhattiya which is a summary of mathematics of his time. - First time he had calculated the value of pi at 3.1416. - He showed that zero was not a numeral only but also a symbol and a concept . Infact the discovery of zero enabled Aryabhatta to find out the exact distance between the earth and the moon. And zero discoveries opened a new dimension of negative numerals. ...
