Cont...  (THE MODERN SCIENCE WAS STARTED IN ANCIENT INDIA).

In our last post we have known about 3 great scientist of Ancient India.

If you haven’t yet go through my last post please go through that before reading this.

Let’s know about few more.

4. Sign convention

Symbols, signs and mathematical notation were employed in an early form in in India by the 6^th century when the great mathematician and astronomer the Aryabhata recommended the use of letters to represent unknown quantities. Here again the great mathematician has teach the world how to count.

Aryabhata was also responsible for discovery of Motion of Solar System and Eclipses. we will discuss about it in another post in details. 

5. Pascal’s Triangle

Described in the 6^th century CE by Varahamihira and in the 10^th century by Halayudha, commenting on the obscure reference by Pingla (the author of an earlier work on prosody) to the “Meru -prastaara”, or the “Staircase of Mount Meru”, in relation to binomial coefficients. (It was also independently discovered in the 10^th or 11^th century in Persia and China.)

6. Brahmagupta’s Finite Difference Interpolation

The Indian mathematician Brahmagupta presented what is possibly the first instance of finite difference interpolation around difference interpolation around 665 CE. He had begun using abbreviation for unknowns by the 7^th century. He employed abbreviations for multiple unknown occurring in one complex problem. Brahmagupta also used abbreviation for square roots and cube roots.

7.Gradational Theory

Gravity was first shown up in surya siddhanta. 1200 years before Sir Isaac Newton born on Earth, Bhaskar Acharya has came out with the Law of gravity. Brahamagupta, the Indian Astronomer and Mathematician whose work influenced Arab mathematician in the 9^th century, held the view that the earth was spherical and that it attract objects towards it. A theory which was later further established in detail by Greek Philosopher Aristotle. And everyone knows the rest story or history you can say.

8. Cataract surgery

Cataract surgery was known to the Indian physician Sushruta (3^rd century CE). In India, cataract surgery was performed with a special tool called Jabamukhi salaka, a curved needle used to loosen the lens and push the cataract out of the field of vision. The eye would later be soaked with warm butter and then bandaged. Greek philosophers and scientists travelled to India where these surgeries were performed by Physicians, and took this practice to the western world.

9. Ayurvedic and Siddha medicine

Ayurveda and siddha are ancient systems of medicine practiced in south Asia. Ayurvedic ideas can be found in the Buddhist Canonical writings (mid-first millennium BCE). Ayurveda has evolved over two thousand years, and is still practiced today.

So this are some awesome discoveries or inventions made by Indians but very very few people know regarding it.
