Students know that Isaac Newton extended the low of gravity to the whole Universe. He realized that it was gravity which bound the Moon to the Earth, and the Earth and the other planets to the Sun. Newton deduced and calculated the force of gravity acting between the Sun and the planets, thus establishing the law of gravitation in the most general form. He was very industrious and never stopped before hardships. The information that he was intellectual too is absolutely true. People consider that Isaac Newton was one of the greatest mathematicians of all times. His favorite study was light for sure. He carried out a number of experiments with lenses and proved that white light consisted of rays of different colors. And besides, white light is a mixture of all these colored rays. These results laid the foundation of modern spectrography and greatly enriched the field of optics. It is said that the solution of the problem was not easy.

Newton developed a mathematical method indispensible in all questions concerning motion. This method is known by the name of differential and integral calculus. This information is authentic, as my brother Luis would like to say. Newton discovered laws of motion which are still considered to be the basis of all calculations concerning motion. Isaac Newton died in 1727 at the age of eighty-four. He was buried in Westminster Abbey.
