Sir Isaac Newton is one of the most influential scientists of all time. He came up with numerous theories and contributed ideas to many different fields including physics, mathematics and philosophy.
In 1687, Newton published Philosophae Naturalis Principia Mathematica, which is widely regarded to be one of the important books in the history of science. In it he describes universal gravitation and the three laws of motion, concepts that remained at the forefront of science for centuries after.
Newton’s law of universal gravitation describes the gravitational attraction between bodies with mass, the earth and moon for example.
Other significant work by Newton includes the principles of conservation related to momentum and angular momentum, the refraction of light, an empirical law of cooling, the building of the first practical telescope and much more.
