Newton was an English mathematician and physicist, and the greatest scientist of his era. He was born on 4 January 1643 in Woolsthorpe, Lincolnshire. His father was a farmer who died three months before Newton was born. His mother remarried and Newton was left in the care of his grandparents. In 1661, he went to study in Cambridge University where he interested in mathematics optic physic and astronomy. In 1665, the university was closed because of a plague and Newton returned to his hometown. He spent the time 2 years there for began to think about gravity(someone said, he sat under the apple tree in the garden and during his sitting an apple fell on to his head and this case made he got about the gravity that can explain about why every things which have mass go into the air and then it will always go down). And he also use the time to think about the optics, mathematics and working out his idea about calculas too.
In 1667, Newton returned to Cambridge. Two years later, he was appointed professor of mathematics. Newton made the reflecting telescope successed in 1668 that’s made Newton to attention in the scientific community. From the mid – 1660s, Newton conducted a series of experiments on the composition of ligth, discovering that white light is composed of the same system of colours that can be seen in a rainbow and establishing the modern study of optics or behaviour of light.
In 1687, Newton published his single greatest work( with the support of his friend), the ‘Philosophiae Naturalis Principia Mathematica’ (Mathematicle Principles of Natural Philosophy). This showed how a universal force, gravity, applied to all objects in all part of the universe. In 1696, Newton was appointed warder of the Royal Mint, settling in London. He took his duties seriously and campaigned against corruption and inefficiency within the organisation. In 1705, he was elected president of the Royal Society, an office he held until his death. He was knighted in 1705. Newton was a difficult man. He often involved in bitter arguments with other scientist(So this is the cause that I like him because he always has his purpose). He died on 31 March 1727……..
