![]() Mathematics under Gupta Empire In the realm of arithmetic the most important achievement was the discovery of the decimal system of notation. It was based upon the principle of the place value of the first nine numbers and the use of the zero. Geometry attained great heights and many theorems relating to circles and triangles are mentioned. The most famous work in mathematics was that of Aryabhatta, the Aryabhattiyam which was written in 499 A.D. the work deals with arithmetic, geometry and algebra. Trigonometry was also being cultivated during this time. Indians took the lead over the Greeks as far as mathematics is considered. Astronomy under Gupta Empire Astronomy made great progress during the age. Varahamihira and Aryabhatta were the major astronomers. Aryabhatta pointed out that eclipses were caused by the moon coming within the earth's shadow or between the earth. He utilized trigonometry in astronomy. He worked out accurate formulas to measure two consecutive days. He had also obtained correct equation for the planet's orbit. Aryabhatta was much more advanced than the European astronomers. Most probably he began composing his work Panchasiddhahtika in 505 A.D. He discusses in this work the principles of the five astronomical schools, which were considered as the most authoritative one in his time. Of these five schools the Romaka Siddhanta clearly betrays Western influence. This is expected to happen as a result of active trade contacts between the Roman Empire and the Gupta Empire. The Surya Siddhanta is the most important and complete astronomical work of the period. It seems that Greek astronomy served as the basis of the Surya-Siddhanta. The other three schools of astronomy discussed by Varahamihira are the Paitamaha Siddhanta, the Vasistha Siddhanta, and the Paulish Siddhanta. In his work Varahamihira has preserved the essential teachings of these five schools of astronomy. Medicine under Gupta Empire ![]() Astrology under Gupta Empire The Vriddha Garga Samhita is the only work on astrology prior to Varahamihira's Brihat samhita, which is a collection of ancient Indian learning and sciences. Besides the sections on astrology in the Brihat samhita, Varahamihira also composed four other works on astrology, which deal with auspicious muhurtas for marriage, auspicious portents for the expeditions of kings and the time of man's birth, and its influence on his future. Chemistry and Metallurgy under Gupta Empire In the Gupta age no books dealing with Chemistry and metallurgy are found. Nagarjuna is mentioned as a great chemist. The famous Iron Pillar near the Qutub-Minar stands as a silent witness to assert the striking metallurgical skill of the Hindus. This pillar has not yet been rusted or corroded despite it being exposed to rain and sun for the last 1500 years. The use of mercury and iron in medicine shows that chemistry must have been practiced. Varahamihira was a scientist who was comfortable in dealing with astronomy, mathematics, astrology, metallurgy, chemistry, jewellery, botany, zoology, civil engineering, water-divining and meteorology. Science was cultivated with enthusiasm in ancient India and many important discoveries were made which were passed on to Europe by the Greeks and the Arabs. |
