Ever since the Hindu nationalist Bharatiya  Janata Party (BJP) headed by Narendra Modi came to power with a thumping majority in the May 2014 Indian parliamentary elections, Hindu nationalists have been making tall claims about the greatness of ancient Hindu science.

Many of these claims are ludicrous, embarrassing and politically motivated, but not all can be dismissed as trash as the modernists and rationalists do, says Dr Shashi Tharoor, Congress MP, and author of the book Why I am a Hindu.

Tharoor’s assertions are backed by the economics Nobel Laureate, Amartya Sen.

Unfounded Claims

But first, the unfounded claims: The Chief Minister of the North Eastern Indian state of Tripura, Biplab Kumar Deb, came out with a stunner on Tuesday, when he told software experts in Agartala: “We had Internet and satellites when the battle of Mahabharata was fought. If not, how could Sanjaya have given Emperor Dhritarashtra a blow by blow account of the war?”

The Mahabharata is dated at between 8th and 9th Centuries BC.

In 2014, Prime Minister Narendra Modi himself told a gathering of doctors at a Mumbai hospital that “cosmetic surgery” existed in ancient India.

“How could an elephant head be transplanted on the body of a child to make the elephant-headed God Ganesha if cosmetic surgery wasn’t there,” Modi asked.

Union Minister of State for Human Resources Development Satyapal Singh had said Charles Darwin’s theory of evolution was wrong.

In his address at the 105th edition of the Indian Science Congress, Union Minister of Education Harsh Vardhan  said that late physicist Stephen Hawking had once said that the Vedas had a theory of relativity that was superior to Albert Einstein’s E=mc2.

In 2015, the Indian Science Congress had panels on “Vedic Aviation Technology” and “astrology” defying objections from the scientific community.

Real Achievements

But Sashi Tharoor, Congress MP, former Minister, and author of “Why I am a Hindu” strikes a balance between the view of the Hindutva brigade and rationalists who debunk claims made on behalf of ancient Indians.

“It is not necessary to debunk the genuine accomplishments of ancient Indian science in order to mock the laughable assertions of the Hindutva brigade,” Tharoor says in a piece in The Quint.

“It is not incorrect to claim, as Science and Technology Minister Harsh Vardhan as did, that the ancient Indians had anticipated Pythagoras. In fact, the Minister could have added Newton, Copernicus, Kepler and Galileo as well,” he asserts.

The Rig Veda had said that gravitation held the universe together 24 centuries before the apple fell on Newton’s head. Scholars working in Sanskrit anticipated his discoveries of calculus by at least 250 years.

The Surya Siddhanta, written about 400 CE, includes a method for finding the times of planetary ascensions and eclipses. The notion of gravitation, or Gurutvakarshan, is found in these early texts.

In Lost Discoveries by the American writer Dick Teresi says: “Two hundred years before Pythagoras, philosophers in northern India had understood that gravitation held the solar system together, and that therefore the sun, the most massive object, had to be at its center.”

Aryabhata was the first human being to explain, in 499 CE, that the daily rotation of the earth on its axis is what accounted for the daily rising and setting of the sun.

Aryabhata conceived of the elliptical orbits of the planets a thousand years before Kepler, in the West, came to the same conclusion. He even estimated the value of the year at 365 days, six hours, 12 minutes and 30 seconds; in this he was only a few minutes off (the correct figure is just under 365 days and six hours).

The translation of the Aryabhatiya into Latin in the 13th century taught Europeans a great deal; it also revealed to them that an Indian had known things that Europe would only learn of a millennium later.

The Vedic civilization subscribed to the idea of a spherical earth at a time when everyone else, even the Greeks, assumed the earth was flat.

By the fifth century CE Indians had calculated that the age of the earth was 4.3 billion years; as late as the 19th century, English scientists believed the earth was a hundred million years old, and it is only in the late 20th century that Western scientists have come to estimate the earth to be about 4.6 billion years old.

India invented modern numerals (known to the world as “Arabic” numerals because the West got them from the Arabs, who learned them from us).

It was an Indian who first conceived of the zero, shunya; the concept of nothingness, shunyata, integral to Hindu and Buddhist thinking, simply did not exist in the West.

Modern mathematics would have been impossible without the zero and the decimal system; just read a string of Roman numbers, which had no zeros, to understand their limitations, Tharoor asserts.

Amartya Sen

Nobel Laureate Amartya Sen points out ancient mathematical models were shared by Indians with Babylonian, Greek and Roman scholars.

“The Indian mathematicians learned something from Babylonians, Greeks and Romans. They also passed some brilliant new ideas to mathematicians elsewhere in the world,” Sen said at an event held by Infosys Science Foundation in Kolkata in 2015.

According to Sen, the sine in trigonometry, originated in India and went West and found place in the Western civilization through an Iranian scholar, Al-Biruni.

“Al-Biruni, the Iranian mathematician, spent many years in India more than a thousand years ago through the end of the tenth through the early years of the eleventh century,” he said.

Chinese mathematicians as well as the pioneering Arab mathematicians had knowledge of Sanskrit and learnt many scientific formulae through it, he noted.

Indian scholars learned from the outside world and also contributed to various mathematical ideas.

“In the beginning we were directly inspired by what we Indians were learning from the work done in Babylon, Greece and Rome. Indian research was deeply influenced by the knowledge of foreign works on the subject and in turn Indian mathematics influenced the mathematical world,” Sen said.

    Each civilization has learned from its predecessors and its contemporaries and, in its turn, has contributed to further the development of a common human heritage. This is how the history of civilizations has evolved and is continuing to do so. Narrow minded views of an all knowing past of a culture, is a hallmark of ignorance and the consequent fanaticism.

    Many ancient civilizations knew that the solar system was heliocentric, viz., that the planets moved around the sun and not the other way around, not just Hindus. Greeks, Babylonians and a set of people about whom we do not learn in Asia, the Mayans. However that does not mean that they understood gravitational law, biz., that the force of attraction is proportional to the product of masses and inversely proportional to the square of the distance.
    Most importantly, in ancient India as elsewhere science was often done by priests and other religious people, and firm conclusions are difficult to draw. The ancient Mayans knew that the year was 365 days – their temple Chichen Itza is a 4-sided pyramid with 91 steps on each side and one shared one at the top.
    None of these add up to the scientific method that became a part of modern science only from the 15 century on [make a hypothesis, perform an observation, check against hypothesis, if prediction does not match theory make new hypothesis, repeat].

    As to people like Biplab Deb, he should be sent back to high school and forced to take physics – so that he never makes such silly assertions again.

      Very good comment! I agree with you.
