Isaac Newton

Isaac Newton was born to Hannah Ayscough and Isaac Newton on Christmas of 1942. His father died three months prior to his birth. Hannah remarried Reverend Barnabus Smith, leaving the three-year old Newton under the care of his maternal grandmother, Margery Ayscough. Newton attained his preliminary education from The King’s School in Grantham, where he excelled and achieved the top-rank. He then enrolled himself as a sizar at the Trinity College, Cambridge in 1661. It was during his years at the Cambridge that Newton developed an interest in mathematics, physics, optics, and astronomy. A plague epidemic of 1665 forced the shutdown of the college for two year, which Newton spent at his home in Woolsthorpe. It was during these two years of hiatus from regular studies that Newton worked on the development theories on calculus, optics, and law of gravity.

As a professor, Newton was required to serve as a tutor but his special permission gave him a privilege according to which he needed to deliver an annual course of lectures which he delivered on his work on optics. Newton worked on his study of optics over a period of years, investigating about the refraction of light by a glass prism. Newton found out that white light was a mixture of infinitely varied coloured rays that is visible in the rainbow and the spectrum. Furthermore, he determined the fact that the refraction of white light caused by a prism into a multi-coloured spectrum could be recomposed to white light using a lens and a second prism. He even dealt with the fact that white light, when refracted to form colored light, did not change its properties. Newton went on to six years of hiatus during which he withdrew from all sorts of intellectual correspondence. It was during this time that Newton developed on his theory of gravitation and its effects, which he first started during the interval from Cambridge due to Plague.

Newton spent his final years in Cranbury Park in...
