Who invented Calculus? The western books say that Newton invented Calculus. You can see the Sanskrit mathematics texts which were written many centuries before Newton that they contain Calculus. For that
matter, who invented numbers? The Indians.
Who invented Nuclear Physics? Buddhist teacher Pakudha Katyayana taught atomic theory. Maharshi Kanaada of 3rd century, B.C. wrote atomic theory in Vaiseshika Sutras. Agni Purana gives smaller magnitudes. The smallest of them is called Paramaanu which nearly equals one billionth part of a meter. This value tallies with the size of an organic molecule calculated by the western scientists.
Who were the first to calculate the velocity of light?
The Rig Veda
Bhashyam by Sayana Madhava gives the following Sloka praising the Sun:
Yojanam sahasre dve, satadve, dvecha yojane
Ekena nimeshardhena kramamaana namosthuthe
One Yojana equals 15788.8 meters, and half of Nimesha equals 8/75 fraction of a second. This gives the velocity of light as 325940 km/s.
We have to remember here that the above value is an approximate one
intended for easy remembrance, like remembering the value of pi as 22/7.
It is better than the the value 215000 km/s given by Danish astronomer
Ole Roemer in 1676.
Who invented the guns? Indians.
Who invented the ships? Europe has only soft wood trees. The ships made of those woods are good for sailing the Mediterranean or a smaller sea.
They are no good for sailing on the oceans. The ship of Vasco de Gama
was about to collapse when it reached India. It is the Indian marine
engineers who repaired that ship and made it worthy again for sea
travel. Which country has the trees that provide the hardest wood?
India.
Who invented steel? The Rig Veda mentions about steel. Evidence for the
manufacture of steel in ancient times is available in South India.
Arabians used to make a lot of money by selling Indian steel ingots to Europe. In 1746, the queen of Britain had sent a scientist named Benjamin Hauntsman to India to obtain the secret of making steel.
Who invented the aircraft? India had many ancient Sanskrit texts on aeronautics. The Yantra Sarvaswa of Maharshi Bharadwaja, Vimaana Chandrika of Maharshi Narayan, Vyoma Yaana Tantra of Sounaka, and Vyoma Yaanarka of Dandi Natha are some of them.
They contained topics like Maargadhi Karana(Navigation and control of speed during flight),
Lohaadhi Karana(alloys used for various components of the aircraft) and
Saktyaadhi Karana(production and usage of various fuels used in
aircrafts).
Who invented powder metallurgy? The Indians. The iron pillar in Delhi
which does not get rust even today is the proof for it.
Who invented plastic surgery? The Indians. It is fully described by Maharshi Susruta, the ancient Ayurvedic surgeon, in his Samhita. Who invented acupuncture? The Indians. Who invented the martial arts? The
Indians. Who invented the remote sensing and imaging techniques? The Indians. Who discovered Advanced Astrology? The Indians. Who discovered Advanced Astronomy? The Indians. Who discovered Groundwater Hydrology?
The Indians. We can read Brihat Samhita of Varaha Mihira; the Indian
method is better than the modern techniques of using space satellites.
Who were the first to construct planned cities with high technology infrastructures for water supply and sewerage? The Indians.
Who invented the hanging bridges? The Indians. Chinese who visited India a few thousands of years ago wrote about our hanging bridges which used steel beams and steel ropes. Who discovered higher philosophy? The Indians.
Were there Doora Sravana and Doora Darsana machines in ancient India?
Yes. Did our ancients knew about radars and laser weapons? Yes, the techology was given in the Sanskrit manuscript Samarangana Sutra Dhara.
Who discovered Irrigation Engineering? Another name for India was Yilaa Varta. The hidden meaning of this name is Jala Maaruta, the country of water laden winds. No other country in the world has monsoons. The
rainfall in India is more than the total rainfall in the rest of the world. India is the land of mighty rivers. In the olden days, the water flow rate in the Ganga exceeded that of any other river in the world.
The people of South India built and maintained an extensive system of irrigation tanks and associated canals with extraordinary managerial and social skills. They shared the waters following the ways of nature from
time immemorial.
Construction of small dams at every possible location was carried out with such completeness that a British engineer of the 19th century felt that it would be impossible to add another tank to that irrigation system. It was a marvel of Indian engineering and human cooperation. Nothing like it existed else where in the world at any time in the past. While peasants of other countries broke their backs to reap one harvest, the Indians produced two or three bumper crops a year. The harvest in the Krishna and Kauvery river basins was large enough to meet the needs of rest of our country during periods of crisis. Visitors from Europe and China in pre-Christian times wrote that India was a land of plenty. Our Buddhist and Jain religious records also say the same thing.
Why India was called Bhaarata Desam? Most of the people of the present generation think that our country was named after emperor Bharata. This interpretation is probably not very old, may be some
hundreds of years. Is there any other land in the world which is named after a male? Religions of all lands treat the earth as a female, the mother goddess. Prior to the spread of Christianity, all countries in
Europe were named after the local mother goddesses. The same is true for all other lands in the world. Among all countries in the world, India has inherited the largest number of ancient manuscripts from time immemorial. They were written on the widest range of subjects known to humans. Indians were the originators of all higher knowledge in the ancient times.
What is impossible for our Maharshis of yore? A Telugu poet wrote the following line: "Pogadaraa nee thalli bhoomi Bhaarathini" - praise your mother land Bhaarati! India was named after Bhaarati (Saraswati), the goddess of knowledge. No other ancient civilization of the world could claim this coveted title. The world’s oldest educational institutions were located in India, and scholars from China and Europe used to come here for learning. Another hidden meaning of the name Yilaa Varta is Bhaarati Aalaya, the temple of goddess Bhaarati.
