We all know that science is the way of comunication with the nature. People are trying to learn the way of communicating with the mother nature since the ancient time. Ancient Indians were one of the most intelligent civilization at that time. The people of that civilization invented and observed so many ways to understand the mother nature that in modern days, we still are using them. Some of the ancient Indian scientists and there contributions:

1️⃣Budhyana: Budhyana was the first person who calculated the value of √2. He also provided equations similar to Pythagoras theorem in his book “Sulva Sutra."

2️⃣ Aryabhatta: Aryabhatta calculated the value of “pi” correctly. His formula,

((4+100)x8+62000)/20000 = 3.1416

He told us that pi is a irrational number. He also discovered the formula of calculating the area of a triangle.

3️⃣ Bramhyagupta: He was the one who introduced us with 'zero' (0). He also used multiplication techniques similar to the modern way. Arabs learned indian mathematics by his book "Brahm Sputa Sanghiya."

4️⃣ Bhaskaracharya: He was the writer of the book, “Siddhanta Siromoni”, which contains arithmetic, algebra, sphere and mathematics of planets. He invented the cyclic method of solving algebra.

5️⃣ Mahaviracharya: He discovered the way of calculating LCM. His book “Ganit Sara Samhita” is about algebra which is much similar to modern algebra.

6️⃣ Varahamihira: He worked in the field of mathematics and astronomy. He improved the accuracy of sine table. Also he invented the algebraic properties of 0 and -ve numbers. He describes about 5 astronomical systems in his book “Panchasiddhantika." He also identified the flora and fauna to locate groundwater.

7️⃣ Nagarjuna: He was a dedicated researcher of chemistry and alchemy. He developed the way of gold plating. In his book “Rasaratnakara”, he provided detailed method of extracting metals.

8️⃣Atrey Rishi: He is the author of the book “Atreya Samhita” which is one of the oldest books about medical science.

9️⃣Charaka: He was the writer of “Charak Samhita” which contains cause and treatment of various diseases.

🔟 Sushruta: He was the father of surgery. In his book “Sushruta Samhita”, he mentioned about more than 1000 diseases and 700 medicinal plants.
