Newton,+Isaac4



Isaac Newton did a lot of work in astronomy, mathematics, and physics. After watching an apple fall from a tree, Newton developed the law of gravitation. He figured the same force that attracted the apple to the ground applied to other matter, also. Newton, also developed a form of mathematics called calculus. Then in 1668, Newton invented the reflecting telescope, which finally brought him to the attention of the scientific community. From the mid-1660s, Newton conducted a series of experiments on the composition of light, discovering that white light is composed of the same system of colors that can be seen in a rainbow and establishing the modern study of optics. In 1704 Newton published 'The Opticks' which dealt with light and colour.  In 1687, with the support of his friend the astronomer Edmond Halley, Newton published his single greatest work, the 'Philosophiae Naturalis Principia Mathematica' ('Mathematical Principles of Natural Philosophy'). This showed how a universal force, gravity, applied to all objects in all parts of the universe.
