Abstract

As is known that the roots of Indian civilisation appeared in Mohenco Daro and Harappa beginning from 5000 BC. and continued to improve in the course of time. Astronomical studies began with the research studies on celestial bodies. Indian astronomers used mathematical studies as auxiliary subject in order to account the velocities of their motions and their irregularities depending on geocentric system. Indian astronomers like Aryabhata and Bragmagupta used eccentric and epicycle system in order to correct the certain faults of geocentric system. In mathematics, especially in arithmetic, Indian made valuable contributions. They used zero at very first time. They used decimal system and offered the symbols that we used nowadays. Behalf of chemistry Indian chemist or in better word Indian alchemist were interested in practical part of it including in theoretical part. In Indian medicine Caraca and Susruta are the two important medical work used as handbooks and translated into Arabic. They had great influence on Islamic medicine. They consisted of explanation of human anatomy, physiology, treatments of diseases and drugs. In India there were three medical school that helped the improvements of medical science theoretically and practically. As a conclusion we can say that Indian civilisation made precious contributions in all the branches of science, as our numeric system, certain trigonometric functions and the system of trigonometry in mathematics. They recommended certain drugs and explanation of new medical systems that showed the importance of keeping health instead of treatment of diseases. It is the first time that ageing was studied. In addition to it, Indian physicians applied esthetical operation at first time.
