Bharat has always been the top contributors in the field of science. But after facing so many invaders and more than 500 years of foreign rule, those glories faded away. Let us see some of those great sages whose contribution towards mankind is unmatchable.

1. Aryabhatta :-

Person who calculated value of Pi and gave the concept of zero. His most notable work was Aryabhatiya. In this he gave proper systematic representation of time and mensuration units. There is a table of sines (jya), given in a single verse. In the same book he covered AP, GP and polynomial equations. He gave method to calculate positions of planets for a given day. He also explained shape of earth and defined the cause of day and night occurrence.

2. Bhaskaracharya II :-

He wrote a book named The Siddhānta-Śiromani. The book has three parts Līlāvatī, Bijaganita and Grahaganita. As the names suggest (except first one, it was his daughter’s name), the Līlāvatī covers arithmatic maths, Bijaganita covers algebraic maths and last one covers mathematical equations related to planets.

3.  Maharshi Bhardwaj :-

His achievements are already mentioned in many Puranas. But his most notable work was on flying machines.  He has described three categories of flying machines: (1) One that flies on earth from one place to another. (2) One that travels from one planet to another. (3) And one that travels from one universe to another. It is said that his work on the art of flying is unparalleled.

4. Aacharya Charak :-

Nearly everyone knows about him. His books Arthashastra and Chanakya Niti are one of the most popular books ever written in India.

10. Varāhamihira :-

Varahamihira proposed that the Moon and planets are lustrous not because of their own light but due to sunlight.

12 Panini :-

In his book, Aṣṭādhyāyī , he described Sanskrit grammar to a great extent and it is considered as one of the finest book on language ever written. In designing his grammar, Panini used the method of “auxiliary symbols”, in which new affixes are designated to mark syntactic categories and the control of grammatical derivations. This technique, rediscovered by the logician Emil Post, became a standard method in the design of computer programming languages.

13. Brahmagupta :-

Brahmagupta was the director of the astronomical observatory of Ujjain, the centre of Ancient Indian mathematical astronomy. He was the first to use mathematics to predict the positions of the planets, the timings of the lunar and solar eclipses. In his methods of multiplication, he used place value in almost the same way as it is used today. He introduced negative numbers and operations on zero into mathematics. Brahmagupta was the first person in history to see zero as a number with its own properties and said that zero divided by any other number is zero.

14. Garga Muni:-

19. Kanv :-

These are only few. Many works of our great sages was copied by west and they presented the world that work as their own. Our education system shamelessly glorifies those westerns and our glorious past is somewhere lost in the old books kept in libraries.
