Why is Newton called the Father of Physics?

Did you know that Sir lsaac Newton is considered as one of the greatest scientists and mathematicians of all time? Newton was born on December 25, 1642 at Woolsthorpe in Lincolnshire, U.K. As a child, Newton was very fond of making mechanical toys. He was enrolled into school at the age of 12 and at 18, he went to Trinity College at Cambridge University, where he exhibited keen interest and aptitude for mathematics. Later in 1669, he was appointed professor of mathematics in the same college. It is said that one day in 1665 while sitting in a garden, Newton saw an apple falling to the ground. A question immediately struck his mind — “Why did the apple fall down? Why didn’t it go upwards?” Puzzled by these questions, he set to work on the problem till he finally found the ‘Law of Universal Gravitation’. According to this law, every body in this Universe attracts every other body with a force directly proportional to the product of their masses and inversely proportional to the square of the distance between them. Through the same law Newton also established the fact that the Earth attracts all objects towards its centre. That is why anything thrown upwards falls back to the Earth. Newton’s scientific experimentation helped demystify several mysteries of nature. He was the first to discover that sunlight, which appears white, is a combination of seven colours. He successfully split sunlight into these seven colours with the help of a prism and also demonstrated that a mixture of these seven colours produces white light. He also invented the first reflecting telescope. His work on light and colour was published in 1704 in a book called Opticks. Newton is also credited with the formulation of the three ‘Laws of Motion’, invention of calculus and several other important discoveries, which have been published in his book Principia. It is one of the most important books of science ever published. Because of these important contributions to physical sciences, Newton is fittingly called the ‘Father of Physics.’ In 1689, Newton was elected as a member of parliament. In 1703, he was elected President of the Royal Society and was reelected as president every year until his death on March 20, 1727. n
