Physics

Physics 'Knowledge of nature' Who named Physics? The History of Physics - Before Aristotle: Atomism and Natural Laws. Thales was the first physicist and his theories actually gave the discipline its name. He believed that the world, although fashioned from many materials, was really built of only one element, water, called Physis in Ancient Greek. Physics is considered to be one of the primitive subjects and academic disciplines to be discovered. It encompasses the study of matter, its motion and behaviour along with energy and force. As a vast discipline, it intersects with many different subjects and disciplines such as biophysics and quantum chemistry. Physics very often defines a wide range of principles and methodologies studied by other areas of sciences. It also suggests new areas of research for other academic fields, even mathematics and philosophy . Branches of Physics 1:Classical Physics Among the popular branches of ph...

Aryabhatta

You will be surprised to know that a lot of scientific knowledge was evolved in ancient India, so many years ago. During this period Science and Mathematics were highly developed and Ancient Indians had contributed immensely. Ayurveda is the indigenous system of medicine that was developed in Ancient Period. Even the science of Yoga was also developed as an allied science of Ayurveda. In this article we will see the contributions of some scientists of ancient India. 1. Aryabhatta He was a fifth century mathematician, astronomer, astrologer and physicist. - At the age of 23, he wrote Aryabhattiya which is a summary of mathematics of his time. - First time he had calculated the value of pi at 3.1416. - He showed that zero was not a numeral only but also a symbol and a concept . Infact the discovery of zero enabled Aryabhatta to find out the exact distance between the earth and the moon. And zero discoveries opened a new dimension of negative numerals. ...
