Achievements in Science and Technology in Ancient India

Why is it in the news?

1.The noted historian William Dalrymple wrote the “Golden Road : How Ancient India Transformed the World?”. The book was published earlier this year, which gives the complete idea as to how India was everything that happened in the ancient world right up to the early stages of the rise of Islam. 

2.According to him, India, not China, was at the heart of ancient commerce. It was the bristling maritime trade between India and the rest of the world which boosted international trade. That India was indeed a maritime power touching Egyptian ports to the West and Indonesia and the rest of SouthEast Asia to its East. The outcome of this association was the construction  of the largest Hindu Temple complex at Angkor Wat in Cambodia and Borobudur, the world’s largest Buddhist shrine in Indonesia. 

3. Through the ages scholars, kings, caliph, emperors across the world from China to Western and Central Asia admired India as the principal knowledge hub even after the advent of Islam. India’s rich mathematical and astronomical tradition continued to dazzle the world. The Chinese emperors gave shelter to Indian mathematicians, astronomers, and scholars in their courts. 

4.The Historian William Dalrymple, brought out how ancient India was as great and as dynamic civilisation as China was at a time when the west was hardly in reckoning. According to him, Indians made astonishing advances in science and technology in ancient India. 

Achievements in Science and Technology in ancient India

1.Ancient Indians made three important contributions. These are the notation system, the decimal system and the use of zero. The notational system was adopted by the Arab who spread it to the western world. The decimal system was borrowed by the Chinese from Buddhist missionaries. Similarly, Indians invented Algebra which was acquired by Arabs and spread to the western Europe. Brahmagupta and Bhaskaracharya further contributed in the development of Algebra and trigonometry. 

2. Zero was discovered by Indians in about the 2nd century BC. It was considered a separate numeral. The Arabs learnt the use of zero and then spread it to Europe. 

3. Aryabhatt calculated the positions of the planets. He discovered the cause of the solar and lunar eclipses. He measured the circumference of the Earth. He said that the Earth rotates around the Sun rather than vice-versa. He wrote Aryabhatiya. 

4. In the book Brihat Samhita, Varahmihir said that the Moon rotated around the Earth and Earth rotated around the Sun. 

5. In the field of medicine, Sushruta and Charak were prominent surgeons and physicians respectively. While Sushruta in his book Sushruta Samhita gives detailed description about the method of operating cataract, stoned diseases and many implements to be used for surgery, the Charak Samhita discusses various types of diseases and prescribes medicines for their cure. 

6. The drainage system and town planning adopted by the Harappans clearly show that they had knowledge of measurement and geometry. Sulba Sutras provides early examples of geometry. It provides precise methods to construct altars. Aryabhatt formulated a method for calculating the area of a triangle which led to the origin of trigonometry. The ancient Indians developed temple building engineering. The marvellous Ellora temples and Kailashnath temple which have been carved out from the single rock is an example of extraordinary engineering feat. 

7. The Lokayat philosophy provided by the Charvak argued that what is not experienced by man through his sensory organ does not really exist. Thus, he repudiated the existence of god. Similarly, philosophy of Sankhya was propounded by Kapil Muni. According to him, the soul can get liberation only through real knowledge which can be acquired through perception, inference and hearing. 

8. Indians developed the art of dyeing, the lasting colour is found in the paintings of Ajanta. 

9.Indians developed great expertise in the art of making steel. The iron pillar at Mehrauli (Delhi) did not rust even after the lapse of 1600 years. 

10.Kanad Rishi devises the atomic theory. He speculated about the existence of small indestructible particles much like an atom. He further held that atoms of the same substance combined with each other in a specific and synchronous manner  produced dviyanuka (diatomic molecules) and tryanuka (Triatomic molecules). 

11. India was the first to smelt zinc by the distillation process. This led to the making of bronze alloy by the mixing of tin with zinc. 

Decline of Science and Technology in India 

The science and technology declined after the onset of Muslim rule in India. The Sultanate period and thereafter, the Mughal period saw the growth of orthodox elements in the society. The Muslim religious leaders like Ulema, Mullah and Maulavi increased religiosity in the society. Among Hindus, the Bhakti movement took its root. The religious leaders like Ramanuja, Madhavacharya, Vallabhacharya, Nanak, Kabir, Tulsidas, Surdas, Mirabai spread the Bhakti cult in India. Thus, the ecosystem of science and technology was relegated to the background. Religious orthodoxy took precedence over logic and scientific temper. Moreover, the progressive and learned Brahamanas were denied privileges like land grants during the Muslim rule and so their creativity was stifled. The status of education further deteriorated during the period. And thus, India lagged behind in science and technology in the mediaeval period.  It was only after the second half of the British rule that science and scientific studies were given importance. Thus, the scientists like J C Bose, C V Raman, Homi Jehangir Bhabha,  Srinivasa Ramanujan, Vikram Sarabhai, Satyendra Nath Bose and Subrahmanyan Chandrasekhar were produced in India who made marks in the field of science and technology.
