Sir Isaac Newton was born on 25 December 1642 and is believed to be the greatest and most influential scientist who ever lived. Newton was an English physicist, mathematician, astronomer and theologian who worked on many practical experiments and laid the foundation for the principles of classical mechanics. He was one of the best minds of all time.
He was sent to The King’s School, an educational institution for boys in Grantham, Lincolnshire when he was 12. Biographer N. W. Chittenden remembers that the young Newton was not a good student in early years of his education. When he was 15, his mother was widowed for the second time and for financial reasons he was taken out of the school to manage a farm. He did not like the work and often neglected his duties, He instead took advantage of his market trips into Grantham to read and study. His deep interest persuaded his mother to send him back to school to complete his education.
After schooling, Sir Isaac Newton entered the Trinity College at Cambridge in 1661 at the age of 16. He was more interested in carrying out his own research than following the professors. He transferred to Cambridge University.
His contribution to mathematics includes the invention of generalized binomial theorem which later developed into the mathematical theory of “Calculus”. He gave philosophies for theories of planetary motion and gravity.
Many principles of physics have the great research and work of Newton behind them. He even laid foundations for the theory of light and color. He was more inspired by modern minds like Descartes, Galileo, John Wallis and Johann Kepler. In 1666 Newton performed a number of experiments on composition of light It was Newton who proved that prisms separate colors.
His invention of the first refracting telescope was based on the same theory that he developed that a prism decomposes the white light into many colors from the visible spectrum. He was also offered membership of Royal Society in 1671, for his interest in optical works and got great reputation.
Newton hesitated in publicizing his mathematical studies as he feared opposition. It was in 1687 that his first edition of his Philosophiæ Naturalis Principia Mathematica (later translated in 1825 as The Mathematical Principles of Natural Philosophy) was published. He described the universal gravitation and the three laws of motion, derived from Kepler’s Laws in his book.
