  • Swami Vivekananda stated India’s Gifts to the World i.e. invented base ten number system & zero, mapped the sky and assigned motion to the Earth in astronomy, developed a sophisticated system of medicine with its mind-body approach i.e. Ayurveda, mastered metallurgical methods of extraction and developed science of self-improvement i.e. yoga.

This is a powerful nation having a large population, and a rich kingdom (possession). Hind is known for the wisdom of its people. Over many centuries, all the kings of the past have recognized the ability of the Hindus in all the branches of knowledge.’ This is how Sayid al-Andalusi (1029 – 1070), a noted eleventh century natural philosopher from the Muslim Spain, described Bharat in his book, Tabaqat al Umam (Book of the Categories of Nations). This book is perhaps the first book ever written on the global history of science.

 Sayid was a Muslim who served as the chief judge (Qādi or Kāzi) in Toledo and resolved conflicts among Muslims using Sharia’s laws—obviously an influential position. In his book, Sayid analyzed the scholarly contributions of various nations and divided them in two categories: nations that made significant contributions to science and the nations that did not contribute much to science. In his list of nations who contributed to science, he chose eight nations: the Hindus, the Persians, the Chaldeans, the Greeks, the Romans, the Egyptians, the Arabs and the Hebrews. 

According to Sayid, ‘[t]he Hindus, as known to all nations for many centuries, are the metal (essence) of wisdom, the source of fairness and objectivity. They are peoples of sublime pensiveness, universal apologues, and useful and rare inventions.’ 

Why Sayid assigns ‘useful and rare inventions’ as a contribution of the Hindus? What are these inventions? 

In support of his statement, Sayid cited the disciplines of Mathematics, Astronomy, and Medicine, where the Hindus made seminal contributions. Science provides materialistic benefits to humanity. Nations leading in science generally have better economies. How was the economy of Bharat during the ancient period?

Dr Angus Maddison (1926–2010), a distinguished British economist who taught at the University of Groningen, the Netherlands, wrote a book, Contours of the World Economy: 1–2030, in which he compiled the Gross Domestic Products (GDP) of various nations during the past two millennia. Following were his results for the GDP of Bharat:

The above table tells us that the Bharat’s economy was close to one-third of the world’s economy at the beginning of the Christian era. The only other nation which was comparable to Bharat was China. All other nations, particularly the European nations, were much behind Bharat in economic prosperity. No wonder, Bharat was popularly labeled as sone ki chideya (golden sparrow).

One can see the downward trend of Bharat’s GDP for several centuries. Fortunately, the trend is currently reversing and Bharat’s share of Global GDP in 2023 was 9.4%. Due to colonization and subjugation of Bharat for about a millennium, such awareness was restricted to small number of scholars at the end of the nineteenth century. At that time, Bharat was synonymous with poverty and illiteracy. 

In such literary environment, Swami Vivekananda first visited America in 1893 and gave his iconic speech at The Parliament of Religions in Chicago on September 11, 1893. His speech caught the attention of the Western world, catapulted him to a much wider audience, and he lectured extensively in America. One such speech was covered by the Brooklyn Standard Union newspaper, New York, on February 27, 1895. The title of the article was, India’s Gift to the World, and had the following information: 

Swami Vivekananda, the Hindoo monk, delivered a lecture Monday night under the auspices of the Brooklyn Ethical Association before a fairly large audience at the hall of the Long Island Historical Society, corner Pierrepont and Clinton streets. His subject was ‘India’s Gift to the World’. 

He spoke of the wondrous beauties of his native land. … Then the lecturer showed in rapid details, what India has given to the world. … India has given to antiquity the earliest scientifical physicians, and, according to Sir William Hunter, she has even contributed to modern medical science by the discovery of various chemicals and by teaching you how to reform misshapen ears and noses (so-called plastic surgery). Even more it has done in mathematics, for algebra, geometry, astronomy, and the triumph of modern science-mixed mathematics-were all invented in India, just so much as the ten numerals, the very cornerstone of all present civilization, were discovered in India, and are in reality, Sanskrit words.

Let us explore further the above statement of Swami Vivekananda that was published in a newspaper in New York. 

Bharat’s main contribution is in the invention of the numeral system, the Hindu numerals, where there are ten symbols (from one to zero, the last numeral invented was zero) and the location of these numbers define their magnitudes. In a base-10 positional- or place-value system, a number, represented as x4 x3 x2 x1 can be constructed as follows: x1 + (x2 × 101 ) + (x3 × 102 ) + (x4 × 103 ) 

Where x4, x3, x2, and x1 are nonnegative integers that have magnitudes less than the chosen base (ten in our case). As you may have noticed, the magnitude of a number increases from right to left. For example, the number 1234 will be written as 4 + (3 × 101) + (2 × 102) + (1× 103). 

After this numeral system became prevalent in Bharat, it spread to nearby regions. Soon, these numerals were commonly used in Persia and the Middle East. The medieval Islamic natural philosophers were quite truthful in giving credit to other civilizations. Owing their gratitude to the Hindus, numerals were always called arqam hindiya in Arabic, literally meaning the Hindu identity. Al-Biruni (973-1051), Al-Khwarizmi (9th cent.), Ibn Labban (ca. 971-1029), and Al-Uqlidisi (920-980) were some of the leading mathematicians of the medieval Islamic period. These natural philosophers are known as much for preserving and transmitting Hindu knowledge of mathematics in the Middle East, that was later passed to the Europeans, as they are known for their own creative work.

In some regions of the world, a few local patriots did not like this foreign Hindu system as it was indicative of Hindu dominance. Severus Sebokht (died, 662 CE), a Syrian natural philosopher mentions of such a rivalry between the Greek and Hindu numerals. He writes:

I will omit all discussion of the science of the Hindus, a people not the same as Syrians, their subtle discoveries in the science of astronomy, discoveries which are more ingenious than those of the Greeks and the Babylonians; their valuable method of calculation; their computing that surpasses description. I wish only to say that this computation is done by means of nine signs. If those who believe, because they speak Greek, that they have reached the limits of science, should know these things, they would be convinced that there are also others [Hindu] who know something.

This quotation is a proof that the Hindu numerals were in practice in Arabia by the seventh century. Also, Sebokht considered Hindu astronomy and mathematics at par with the Greek astronomy and mathematics.

At the end of the second millennium, in year 2000, The American Association for the Advancement of Science (AAAS) compiled a list of the top 100 scientific findings that made significant impacts on the world and published in Science journal on January 14, 2000.

Only two discoveries were chosen from the non-Western world: (1) invention of zero and (2) the astronomical observations of the Hindu and Mayan sky-watchers for agricultural and religious purposes. Both non-Western contributions involved the works of the ancient Hindus. Why Hindu contributions to astronomy were considered so important in human history? Do we teach Hindu contributions to astronomy in school curricula in Bharat?

In astronomy, the spherical shape of the earth was recognized by the ancient Hindus. Aryabhata (476 - 550 CE) used an analogy of a kadamba flower to demonstrate the distribution of various life forms on the Earth:

Half of the sphere of the Earth, the planets, and the asterisms is darkened by their shadows, and half, being turned toward the sun, is lighted according to their size. The sphere of the earth, being quite round, situated in the center of space, in the middle of the circle of asterisms [constellations or stars], surrounded by the orbits of the planets, consists of water, Earth, fire, and air. Just as the ball formed by a kadamba flower is surrounded on all sides by blossoms just so the Earth is surrounded on all sides by all creatures terrestrial and aquatic (Aryabhatiya, Gola, 5-7).

Aryabhata assigned diurnal motion to the Earth and kept the sun stationary in his astronomical scheme. According to Aryabhata, the motion of the stars that we observe in the sky is an illusion. To explain the apparent motion of the sun, he used an analogy of a boat in a river: ‘As a man in a boat going forward sees a stationary object moving backward just so in Sri-Lanka a man sees the stationary asterisms moving backward exactly toward the West.’

The interpretation is that a person standing on the equator of Earth, that rotates from the West to the East, would see the asterisms (constellations or stars) moving in the westward motion. The clear grasp of Aryabhata about Earth’s motion and relative motion are splendidly explained in the analogy of a boat man given above. Clearly, Aryabhata’s earth was not stationary; it certainly had diurnal motion. 

With respect to the field of medicine, Swami Vivekananda mentioned about Hindu physicians and the so-called plastic surgery. Perhaps, he was alluding to the works of Charaka, Sushruta, and Vagbhata.

Ayurveda is the Hindu science of healing and rejuvenation. It is a holistic system of medicine, which is curative as well as preventive. It is a holistic approach which focuses on both mind and body. Dietary measures and lifestyle changes are recommended to delay the aging process at the cellular level and to improve the functional efficiency of body and mind. The basic idea is to create a balance in the body that will allow the body to cure itself.

In ancient India, earlobes or nose were chopped as a punishment for some crimes. For example, in Ramayaṇa, Shurpanakha, sister of Ravana, was punished by Lakshmana and lost her nose and earlobes. In Bharat, repair of such body parts was possible using a surgical process that was made famous by Sushruta. Nasal amputation has also worked its way into the Hindi metaphors and the Hindi term nāk kat gai (nose is chopped) implies that a person is insulted. Also, ‘saving nose’ (nāk bachā lī) is a colloquial term implying to go through difficult circumstances without any embarrassment. 

Sushruta described the technique to graft skin, popularly known as ‘plastic surgery’ these days as a general umbrella term. He is considered as the father of plastic surgery, and the Western world gives credit to Bharat for the method of rhinoplasty surgery. Sushruta repaired noses or earlobes by using an adjacent skin flap. This procedure is popularly called as ‘the Indian method of rhinoplasty.’ Live skin from the thigh, cheek, abdomen, or the forehead was used to make the new artificial body parts. 

In England, the first article on the subject appeared in the Gentleman’s Magazine in 1794 by Colly Lyon Lucas, a British surgeon and member of the Medical Board at Madras, India. He explained the process in his letter to the Editor, describing the process as ‘long known in India’ and not known to the British. Colly Lyon Lucas witnessed a case where a local person serving the British army, in the war of 1792 CE, was captured by King Tipu Sultan. Unable to defeat the British outright, the sultan tried to starve his enemies by ambushing the local bullock drivers who transported grain to the British. 

Tipu decided to humiliate the bullock drivers by mutilating their noses and ears. Lucas discusses the case of one such victim of this practice, the Mahratta bullock driver Cowasjee, who, on his capture, had his nose and one of his hands amputated by Sultan. After one year, this man decided to get his nose repaired. An operation was performed by the Ayurvedic surgeons. In this operation, skin was taken from the forehead, molded, and placed as a nose. The whole process took about 25 days. The artificial nose looked ‘as well as the natural one’ and the scar on the forehead was not very observable after a ‘length of time.’ 

In the United Kingdom, the first operation of rhinoplasty was performed by Joseph Constantine Carpue on October 23, 1814, in front of a large group of surgical colleagues and his students. Carpue performed the second operation on an army officer who lost his nose during the Peninsular War against Napoleon, and later wrote a book about it in 1816. In this book, Carpue attributes this procedure to Bharat from time immemorial: ‘Assuredly, the Hindoos owe no part of their skill in this operation, either to Europe. … all the names I have cited concur in deriving the Indian practice to time immemorial’ (Carpue, 1816, 42). 

An interesting fact is that the surgery was mostly performed by the lower cast people like Koomas (kumhār) or potters and brickmakers, as shared by Carpue.

In this brief article, a glimpse of the prime past of the Hindus is provided in view of Swami Vivekananda’s speech, India’s Gift. To understand modern science as a coherent story, it is essential to recognize the accomplishments of the ancient Hindus. They invented our base ten number system and zero that are now used globally, carefully mapped the sky and assigned motion to the Earth in their astronomy, developed a sophisticated system of medicine with its mind-body approach known as Ayurveda, mastered metallurgical methods of extraction and purification of metals, including the so-called Damascus blade and the Iron Pillar of New Delhi, and developed the science of self-improvement that is popularly known as yoga.

It would be nice if Bharat could attract the best brains to explore and document properly Bharat’s prime past, fulfil the dream of Swami Vivekananda, and preserve the knowledge for the future generations.
