Today whatever the advancement that is taking place worldwide, whether in technology, medicine, cosmic, and health all the praises are sung for the westerners.

However, India on the other side was one of the most renowned and developed nations in the world, contributing 32.00% of the world GDP(3rd BCE-13th CE).

“Many of the advances in the sciences that we consider today to have been made in Europe were in fact made in India centuries ago”.

– Grant Duff (British Historian)
And no other way this could be said more clearly.

Astonishingly, many Indians do not know about their own country’s past and history.
We need to recognize and learn our accomplishments of the past and glorify them.
India, the land of sages and seer, is not just a country of multiple, colorful cultures but the land that gave the world all those that are fundamental blocks of today’s great advancements.


Galileo Galilei, Pythagoras, Aristotle, Newton are some of the great scientists and scholars of the west that are credited for all major discoveries and inventions.

However, ancient Indian scientists like Aryabhatt, Patanjali, Charaka are a few of the gems of the ancient technological world.

The invention of zero-

The invention of “zero” by Aryabhatt in the fifth century is the greatest invention of all time. With the integration of zero in the place value system, the world is now able to write numbers no matter how long.
Lancelot Hogben said:
“There has been no more revolutionary contribution than the one which the Hindus (Indians) made when they invented ZERO”.

Gravitational force-

We remember the Theory of Gravitational Force to be the contribution of Sir Isaac Newton, but in 400-500AD India this was already discovered.
In Surya Siddhanta, Indian astronomer, Bhaskaracharya stated-” All objects fall due to a force of attraction. That is why earth, planets, moon, sun are all in their orbits due to this attraction force”.

The atomic theory was discovered thousand years ago in India

To the world, a 19th century English chemist John Dalton is the father of atomic theory. However, few people know that ancient Indian scientist Acharya Kanada talked about atoms or “paramanu” in his book Kanada Sutras, or Aphorisms of Kanada.

Kanada opined, “paramanu is the indestructible particle of a matter”.

He also mentioned that atoms combine in a specific manner to form dvyanuka (diatomic molecules) and tryanuka (triatomic molecules).


The Discovery of wootz steel is one of the greatest discoveries in the metallurgical sector. It originated in South India, in present-day Tamil Nadu.
“Wootz steel is a crucible steel characterized by a pattern of bands and high carbon conten. The method was to heat black magnetite ore in the presence of carbon in a sealed clay crucible inside a charcoal furnace to completely remove slag”. as per Wikipedia.


Plastic surgery-

Sushruta Samhita is the most important treatise on surgery written by Susruta. It describes the surgical training, instruments, and procedures practiced in modern surgery.
The treatise also deals with diseases and their prevention and cure, following with the number of bones in a human body.
It also thoroughly describes 700 medicinal

Cataract Surgery-

Sushruta, an ancient Indian physician pioneered the first cataract surgery in the sixth century BC.
To remove the cataract he used a sharp needle called Jabamukhi Salaka, to loosen the lens and push the cataract out of the vision. Then the eye is bandaged till the time it gets healed.


Acharya Patanjali is the Father of Yoga. He introduced the Yoga Sūtra of Patañjali in the 2nd century BC which became a very renowned contribution to the world. Through this field of discipline, one can discover his true self and its 84 yogic posture has proved efficient for the proper functioning of different systems, i.e. endocrine, nervous, respiratory, circulatory, etc. The different breathing patterns taught in this discipline aids in calming down the mind, body, and soul and allows them to work in unison.



Yoga is restraining the mind-stuff (Chitta) from taking various forms (Vrttis).​

These were few of the many achievements of our ancient scientists.

At last, the contribution of Ancient Indian scientists to scientific technology is worth dignifying.
To India, the cradle of the eminent leading light, Mark Twain honours-
“India is the cradle of the human race, the birthplace of human speech, the mother of history, the grandmother of legend, and great grandmother of tradition”
