World famous scientist Sir Isaac Newton was born at Woolsthorpe Manor in Lincolnshire, England, on Christmas day in 1642. As a baby Isaac was a weakling Having Lost his father before his birth, he was born prematurely. The widowed mother lost all hope of the baby's survival.she never had the faintest idea that this baby would one day not only become one of the world's greatest scientists, but also live long.
When Newton was two years old. his mother remarried.He was then shifted to his grandmother's house and she raised him. This young boy engaged himself in some activity or other. He made a sundial in stone. Besides, he made a watch that ran on water and a model of a windmill. The sun clock he made is on display at London's Royal Museum. He also loved reading.
When he was 14 year old, his mother was once again windowed. He started living with his mother now, and started helping her at their farm. Soon his mother realized that as he approached adulthood his interest in farming was waning. At home he would daydream. He began making models using wood. Finally, his mother agreed to send him to college. Isaac was thrilled. At the age of 18, newton joined the famous Trinity College at Cambridge. After four years, in 1665, he gained his graduate degree in mathematics from Cambridge University. in college his mathematics professor Isaac Barrow recognized his potential and started encouraging and guiding him and later, became his friend.
And that time plague epidemic raged all over England. About ten per cent of the country's population died of this epidemic. Schools and college were closed. Cambridge University too was closed. Newton was back at his mother's farm. Till the time the university reopened after a year and half, Newton stayed with his mother. The time he spent hare was the most productive period of his life His greatest discoveries were made during this time (1665-66) and is also known as miraculous year in Newton's life. He laid the foundations of the calculus and the laws of motion. He also examined the elements of circular motion and applied his analysis to the moon and other planets. Seeing a falling apple gave him insight into the law of universal gravitation. The seeds of his famous work on optics were also laid then. He later elaborated these and were recognized as the world's greatest discoveries of those times.
In 1667, when the university reopened, Newton was appointed lecture. He made quick progress and in 1669, at the age of 26,he was appointed Lucasian Professor of mathematics in place of Professor Isaac Barrow.
For long Newton was involved in the research on light. Newton's first Work at Trinity College was in optics. While at home, Newton had conducted many experiments in his darkened room with a glass prism. when he let in a chink of daylight between the curtains or a ray of white light passed through a prism, it was refracted.
