5 great scientist of Ancient India

Today I am going to tell about 5 great scientist of Ancient India.

1. Aryabhatta

Arybhatta was mathematician, astronomer, astrologer and physicist. He was  the first messenger in the field of mathematics. In early age of his life, when he was  around 23 years he wrote summary of mathematics ‘Aryabhattiya’, and there are four sections in this scholarly work.

Many people consider that Nicolaus Copernicus was the first scientist who gave the relation between Sun and earth. But Arybhatta hypothesised this relation before 1000 years. He also added that Earth move on its own axis and revolves around sun like other 9 planets  rather than sun revolving around the Earth.

Arybhatta proposed this  relation when Arstu, a  Greek philosopher had proposed that the Center of Universe is Earth and  the rest other planet along  with the  sun revolves around the Earth. Further he added that moon and other planets does not posses light of their own , they shine due to the light of the Sun (they actually reflect the light of the sun and hence they shine).
 He also told about the perimeter of earth which is approximately equal to current result. He divided the time in different sections depending on the rotation of the Earth

But he remained immortal in world after  the discovery of  ‘Zero’ an important part of mathematics .
His contribution in the field of mathematics is unforgetable.

2. Kanad

In  the history of India Kanad  is rated as the first man who proposed atomic theory that matches with the modern atomic theory. Before 900 years of Dalton theory, he told about atoms of matter and also that all physical matter is collection of atoms.

Once Greek Astrologer, TM Colin Beckley too  stated  about Kanad.

kanad hypothesised  the Atomic theory 2600 years  before the modern  atomic thoery. His thoery is much more advanced than the current thoery.

Kanad  even postulated about three laws of motion which was  years later proposed by Newton.

3. Baudhayan

Baudhyan was the first ever mathematician who discover several concepts of math that  were rediscovered in western world, like he calculated the value of pi. He too told about various concept of Geometry before Greek ucladian geometric. In those era Indian algebra and geometry were known as ‘Sulva Sutra’.

We all are familiar with Pythagoras theorem. Do we know that  Kanad had discovered this theory before 250 years Pythagoras ??

4. Bhaskaracharya

Bhaskaracharya is one of the most popular mathematician of India. He is famous for his book Siddanta Shiromani that is divided into four sections: Arithmetic, Algebra, Sphere and mathematics of planets.

 Newton discovered abput gravity and gravitational force few years ago but least number of people know that Bhaskaracharya had discovered gravitational force before 1000 of years Newton did. He had explained about  this theory in his book  "Shiromani".

He introduced chakrawat method or cyclic method to solve algebraic equation but the same method was rediscovered after six century by European mathematician by another name of inverse cycle.

In his another book he explained about ‘Chandra Grahan’ or Lunar Eclipse and ‘Surya Grahan’  or Solar Eclipse.  Chandra grahan occurs when the Earth comes in between the Sun and  the Moon;the Earth comes in front of the Moon. And Surya Grahan occurs when the Moon comes in between the Sun and the Earth;that is Moon comes in front of the earth. That was first written proof when Indian people actually came to know about gravitational force, Chandra Graham and Surya Graham.

His various books  were also published in various languages and in  different countries.

5. Susruta

Susruta was rated as pioneer in field of Surgery. He considered surgery as “the highest division of the healing arts and least liable to fallacy”. Thousands of year he knew over 1100 diseases inculding 20 types of fever, 8 types of Jaundice and 20 types of urinary complaints. He also knew about delivery operation, solutions of Motiabind, plastic surgery and many others.

He wrote Susruta Samhita in which he mentioned 101 surgery equipments and 300 kinds of surgery.This book was  published in various languages and in different countries.

with the help of this book doctors came to know plastic surgery and its operaation.

Susruta has great contribution in the fields of plastic surgery and ophthalmic surgery. When nose cutting and ears cutting was a common punishment during those times he knew about the restoration of these. In his book Susruta Samhita he describes step by step procedure of these operations.
