Ancient Indian Technologies

Science and Mathematics were highly developed during the ancient period in India. Ancient Indians contributed immensely to the knowledge in Mathematics as well as various branches of Science. You will be surprised to know that many theories of modern day mathematics were actually known to ancient Indians. However, since ancient Indian mathematicians were not as good in documentation and dissemination as their counterparts in the modern western world, their contributions did not find the place they deserved.



Baudhayan was the first one ever to arrive at several concepts in Mathematics, which were later rediscovered by the western world. The value of pi was first calculated by him. As you know, pi is useful in calculating the area and circumference of a circle. What is known as Pythagoras theorem today is already found in Baudhayan’s Sulva Sutra, which was written several years before the age of Pythagoras.


Aryabhatta was a fifth century mathematician, astronomer, astrologer and physicist. He was a pioneer in the field of mathematics. At the age of 23, he wrote Aryabhattiya, which is a summary of mathematics of his time. There are four sections in this scholarly work.

In the first section he describes the method of denoting big decimal numbers by alphabets. In the second section, we find difficult questions from topics of modern day Mathematics such as number theory, geometry, trigonometry and Beejganita (algebra). The remaining two sections are on astronomy.

Aryabhatta showed that zero was not a numeral only but also a symbol and a concept. Discovery of zero enabled Aryabhatta to find out the exact distance between the earth and the moon. The discovery of zero also opened up a new dimension of negative numerals.

As we have seen, the last two sections of Aryabhattiya were on Astronomy. Evidently, Aryabhatta contributed greatly to the field of science, too, particularly Astronomy.

AryabhattaIn ancient India, the science of astronomy was well advanced. It was called Khagolshastra. Khagol was the famous astronomical observatory at Nalanda, where Aryabhatta studied. In fact science of astronomy was highly advanced and our ancestors were proud of it. The aim behind the development of the science of astronomy was the need to have accurate calendars, a better understanding of climate and rainfall patterns for timely sowing and choice of crops, fixing the dates of seasons and festivals, navigation, calculation of time and casting of horoscopes for use in astrology. Knowledge of astronomy, particularly knowledge of the tides and the stars, was of great importance in trade, because of the requirement of crossing the oceans and deserts during night time.

Disregarding the popular view that our planet earth is ‘Achala’ (immovable), Aryabhatta stated his theory that ‘earth is round and rotates on its own axis’ He explained that the appearance of the sun moving from east to west is false by giving examples. One such example was: When a person travels in a boat, the trees on the shore appear to move in the opposite direction. He also correctly stated that the moon and the planets shined by reflected sunlight. He also gave a scientific explanation for solar and lunar eclipse clarifying that the eclipse were not because of Rahhu and/or Ketu or some other rakshasa (demon,). Do you realize now, why the first satellite sent into orbit by India has been named after Aryabhatta?


In 7th century, Brahmgupta took mathematics to heights far beyond others. In his methods of multiplication, he used place value in almost the same way as it is used today. He introduced negative numbers and operations on zero into mathematics. He wrote Brahm Sputa Siddantika through which the Arabs came to know our mathematical system.



Bhaskaracharya was the leading light of 12th Century. He was born at Bijapur, Karnataka. He is famous for his book Siddanta Shiromani. It is divided into four sections: Lilavati (Arithmetic), Beejaganit (Algebra), Goladhyaya (Sphere) and Grahaganit (mathematics of planets). Bhaskara introduced Chakrawat Method or the Cyclic Method to solve algebraic equations. This method was rediscovered six centuries later by European mathematicians, who called it inverse cycle. In the nineteenth century, an English man, James Taylor, translated Lilavati and made this great work known to the world.


There is an elaborate description of mathematics in Jain literature (500 B.C -100 B.C). Jain gurus knew how to solve quadratic equations. They have also described fractions, algebraic equations, series, set theory, logarithms and exponents in a very interesting manner. Jain Guru Mahaviracharya wrote Ganit Sara Sangraha in 850A.D., which is the first textbook on arithmetic in present day form. The current method of solving Least common Multiple (LCM) of given numbers was also described by him. Thus, long before John Napier introduced it to the world, it was already known to Indians.




Kanad was a sixth century scientist of Vaisheshika School, one of the six systems of Indian philosophy. His original name was Aulukya. He got the name Kanad, because even as a child, he was interested in very minute particles called “kana”. His atomic theory can be a match to any modern atomic theory. According to Kanad, material universe is made up of kanas, (anu/atom) which cannot be seen through any human organ. These cannot be further subdivided. Thus, they are indivisible and indestructible. This is, of course, as you may be knowing, what the modern atomic theory also says.


VarahamihiraVarahamihira was another well known scientist of the ancient period in India. He lived in the Gupta period. Varahamihira made great contributions in the fields of hydrology, geology and ecology. He was one of the first scientists to claim that termites and plants could be the indicators of the presence of underground water. He gave a list of six animals and thirty plants, which could indicate the presence of water. He gave very important information regarding termites (Deemak or insects that destroy wood), that they go very deep to the surface of water level to bring water to keep their houses (bambis) wet. Another theory, which has attracted the world of science is the earthquake cloud theory given by Varahmihira in his Brhat Samhita. The thirty second chapter of this samhita is devoted to signs of earthquakes. He has tried to relate earthquakes to the influence of planets, undersea activities, underground water, unusual cloud formation and abnormal behaviour of animals.

Another field where Varahamihira’s contribution is worth mentioning is Jyotish or Astrology. Astrology was given a very high place in ancient India and it has continued even today. Jyotish, which means science of light, originated with the Vedas. It was presented scientifically in a systematic form by Aryabhata and Varahmihira. You have already seen that Aryabhata devoted two out of the four sections of his work Aryabhattiyam to astronomy, which is the basis for Astrology. Astrology is the science of predicting the future. Varahamihira was one of the nine gems, who were scholars, in the court of Vikramaditya. Varahamihira’s predictions were so accurate that king Vikramaditya gave him the title of ‘Varaha’.


Nagarjuna was a tenth century scientist. The main aim of his experiments was to transform base elements into gold, like the alchemists in the western world. Even though he was not successful in his goal, he succeeded in making an element with gold-like shine. Till date, this technology is used in making imitation jewelry. In his treatise, Rasaratnakara, he has discussed methods for the extraction of metals like gold, silver, tin and copper.



Aircraft designs from ancient India

The Vaimānika Śāstra is an early 20th-century Sanskrit text on aerospace technology. It makes the claim that the vimānas mentioned in ancient Sanskrit epics were advanced aerodynamic flying vehicles.

The existence of the text was revealed in 1952 by G. R. Josyer who asserted that it was written by Pandit Subbaraya Shastry (1866–1940), who dictated it during the years 1918–1923. A Hindi translation was published in 1959, while the Sanskrit text with an English translation was published in 1973. It contains 3000 shlokas in 8 chapters which Shastry claimed was psychically delivered to him by the ancient Hindu sage Bharadvaja. The text has gained favor among proponents of ancient astronaut theories.

Unlike modern treatises on aeronautics that begin by discussing the general principles of flight before detailing concepts of aircraft design, the Vaimānika Śāstra straightaway gets into quantitative description, as though a particular aircraft is being described. The topics covered include, “definition of an airplane, a pilot, aerial routes, food, clothing, metals, metal production, mirrors and their uses in wars, varieties of machinery and yantras, planes like ‘mantrik’, ‘tantrik’, and ‘kritak’” and four planes called Shakuna, Sundara, Rukma, and Tripura are described in greater detail. The extant text is claimed to be only a small (one-fortieth) part of a larger work Yantra Sarvaswa (“All about machines”) composed by Maharishi Bharadwaj and other sages for the “benefit of all mankind”.



Though ancient India had a significant urban population, much of India’s population resided in villages, whose economy was largely isolated and self-sustaining. Agriculture was the predominant occupation of the populace and satisfied a village’s food requirements besides providing raw materials for hand based industries like textile, food processing and crafts. Besides farmers, other classes of people were barbers, carpenters, doctors (Ayurvedic practitioners), goldsmiths, weavers etc.

Along with the family-run business and individually owned business enterprises, ancient India possessed a number of other forms of engaging in business or collective activity, including the gana, pani, puga, vrata, sangha, nigama and sreni. Nigama, pani and sreni refer most often to economic organisations of merchants, craftspeople and artisans, and perhaps even para-military entities. In particular, the sreni was a complex organisational entity that shares many similarities with modern corporations, which were being used in India from around the 8th century BC until around the 10th century AD. The use of such entities in ancient India was widespread including virtually every kind of business, political and municipal activity.

The sreni was a separate legal entity which had the ability to hold property separately from its owners, construct its own rules for governing the behaviour of its members, and for it to contract, sue and be sued in its own name. The sreni had a considerable degree of centralised management. The headman of the sreni represented the interests of the sreni in the king’s court and in many official business matters. The headman could also bind the sreni in contracts, set the conditions of work within the sreni, often received a higher salary, and was the administrative authority within the sreni. The headman was often selected via an election by the members of the sreni, who could also be removed from power by the general assembly. The headman often ran the enterprise with two to five executive officers, who were also elected by the assembly.


CoinagePunch marked silver ingots, in circulation around the 5th century BC and the first metallic coins were minted around the 6th century BC by the Mahajanapadas of the Gangetic plains were the earliest traces of coinage in India. While India’s many kingdoms and rulers issued coins, barter was still widely prevalent. Villages paid a portion of their agricultural produce as revenue while its craftsmen received a stipend out of the crops at harvest time for their services. Each village, as an economic unit, was mostly self-sufficient.

GPD Estimate

According to economic historian Angus Maddison in his book Contours of the world economy, 1–2030 AD: essays in macro-economic history, India had the world’s largest economy during the years 1 AD and 1000 AD.

During the Maurya Empire (c. 321–185 BC), there were a number of important changes and developments to the Indian economy. It was the first time most of India was unified under one ruler. With an empire in place, the trade routes throughout India became more secure thereby reducing the risk associated with the transportation of goods. The empire spent considerable resources building roads and maintaining them throughout India. The improved infrastructure combined with increased security, greater uniformity in measurements, and increasing usage of coins as currency enhanced trade.

Chanakya — a teacher, philosopher, economist, jurist and royal advisor. He is traditionally identified as Kauṭilya or Vishnu Gupta, who authored the ancient Indian political treatise, the Arthashastra (Economics). As such, he is considered as the pioneer of the field of political science and economics in India, and his work is thought of as an important precursor to classical economics.

ChanakyaOriginally a teacher at the ancient university of Takshashila, Chanakya assisted the first Mauryan emperor Chandragupta in his rise to power. He is widely credited for having played an important role in the establishment of the Maurya Empire. Chanakya served as the chief advisor to both emperors Chandragupta and his son Bindusara.

Two books are attributed to Chanakya: Arthashastra and Chanakya Niti, also known as Chanakya Neeti-shastra.

The Arthashastra discusses monetary and fiscal policies, welfare, international relations, and war strategies in detail. The text also outlines the duties of a ruler. 

Chanakya Niti is a collection of aphorisms, said to be selected by Chanakya from the various shastras.


Medical Science

As you have read, scientific knowledge was in a highly advanced stage in ancient India. In keeping with the times, Medical Science was also highly developed. Ayurveda is the indigenous system of medicine that was developed in Ancient India. The word Ayurveda literally means the science of good health and longevity of life. This ancient Indian system of medicine not only helps in treatment of diseases but also in finding the causes and symptoms of diseases. It is a guide for the healthy as well as the sick. It defines health as an equilibrium in three doshas, and diseases as disturbance in these three doshas. While treating a disease with the help of herbal medicines, it aims at removing the cause of disease by striking at the roots. The main aim of ayurveda has been health and longevity. It is the oldest medical system of our planet.

A treatise on Ayurveda, Atreya Samhita, is the oldest medical book of the world. Charak is called the father of ayurvedic medicine and Susruta the father of surgery. Susruta, Charak, Madhava, Vagbhatta and Jeevak were noted ayurvedic practitioners. Do you know that Ayurveda has lately become very popular in the western world? This is because of its many advantages over the modern system of medicine called Allopathy, which is of western origin.


advance-indian-science-susrutaSusruta was a pioneer in the field of surgery. He considered surgery as “the highest division of the healing arts and least liable to fallacy”. He studied human anatomy with the help of a dead body. In Susruta Samhita, over 1100 diseases are mentioned including fevers of twenty-six kinds, jaundice of eight kinds and urinary complaints of twenty kinds. Over 760 plants are described. All parts, roots, bark, juice, resin, flowers etc. were used. Cinnamon, sesame, peppers, cardamom, ginger are household remedies even today.

In Susruta Samhita, the method of selecting and preserving a dead body for the purpose of its detailed study has also been described. The dead body of an old man or a person who died of a severe disease was generally not considered for studies. The body needed to be perfectly cleaned and then preserved in the bark of a tree. It was then kept in a cage and hidden carefully in a spot in the river. There the current of the river softened it. After seven days it was removed from the river. It was then cleaned with a brush made of grass roots, hair and bamboo. When this was done, every inner or outer part of the body could be seen clearly.

Susruta’s greatest contribution was in the fields of Rhinoplasty (plastic surgery) and Ophthalmic surgery (removal of cataracts). In those days, cutting of nose and/or ears was a common punishment. Restoration of these or limbs lost in wars was a great blessing. In Susruta Samhita, there is a very accurate step-by-step description of these operations. Surprisingly, the steps followed by Susruta are strikingly similar to those followed by modern surgeons while doing plastic surgery. Susruta Samhita also gives a description of 101 instruments used in surgery. Some serious operations performed included taking foetus out of the womb, repairing the damaged rectum, removing stone from the bladder, etc. Does it not sound interesting and wonderful?


charakaCharak is considered the father of ancient Indian science of medicine. He was the Raj Vaidya (royal doctor) in the court of Kanishka. His Charak Samhita is a remarkable book on medicine. It has the description of a large number of diseases and gives methods of identifying their causes as well as the method of their treatment. He was the first to talk about digestion, metabolism and immunity as important for health and so medical science. In Charak Samhita, more stress has been laid on removing the cause of disease rather than simply treating the illness. Charak also knew the fundamentals of Genetics. Don’t you find it fascinating that thousands of years back, medical science was at such an advanced stage in India.

Yoga and Patanjali


The science of Yoga was developed in ancient India as an allied science of Ayurveda for healing without medicine at the physical and mental level. The term Yoga has been derived from the Sanskrit work Yoktra. Its literal meaning is “yoking the mind to the inner self after detaching it from the outer subjects of senses”. Like all other sciences, it has its roots in the Vedas. It defines chitta i.e. dissolving thoughts, emotions and desires of a person’s consciousness and achieving a state of equilibrium. It sets in to motion the force that purifies and uplifts the consciousness to divine realization. Yoga is physical as well as mental. Physical yoga is called Hathyoga. Generally, it aims at removing a disease and restoring healthy condition to the body. Rajayoga is mental yoga. Its goal is self realization and liberation from bondage by achieving physical mental, emotional and spritiual balance.

Yoga was passed on by word of mouth from one sage to another. The credit of systematically presenting this great science goes to Patanjali. In the Yoga Sutras of Patanjali, Aum is spoken of as the symbol of God. He refers to Aum as a cosmic sound, continuously flowing through the ether, fully known only to the illuminated. Besides Yoga Sutras, Patanjali also wrote a work on medicine and worked on Panini’s grammar known as Mahabhasaya.
