Sir Isaac Newton is known for his work in the fields of physics, mathematics, optics, astronomy, gravitation, chemistry, and philosophy.

__**Gravitation and Mechanics**__ He is greatly known for his theory of gravity, As tradition has it, in 1666 Newton witnessed an apple fall from a tree, this led him to pursue the idea that Earth's gravity went into space and acted upon the moon. He believed that the same force governed both the falling apple and the position and path of the moon. Years later he concluded on his theory of gravity, which is still used today. He published his idea along with his other work on mechanics in his first book //Principia I.// In his book he stated that gravity controlled all celestial bodies and that a planets path is in the shape of an ellipse. His theory was revolutionary at the time because the accepted idea was that gravity effected everything on Earth but did not go farther than that. Also at the time no one could figure out the shape of a planet's path.

Newton's theories on on color refraction and optics were greatly disputed at the time. Other scientists did not believe him due to the standards of the time and their understanding of colors. Also one scientist attempted to recreate his experiments but failed. This led Newton to postpone the publication of his paper, //Opticks//, until all of his critics had died. His theories were revolutionary because he was able to solve problems that no one else had been even close to solving.

__**Mathematics**__ Even at a young age, Newton's brilliance in mathematics was clearly present. He contributed to all fields of mathematics during his lifetime. He is greatly known for his solutions to problems with drawing tangents to curves and defining areas bound by curves. In the 1690's a dispute was started over Newton's methods of calculus compared to Gottfried Wilhelm Leibniz, another mathematician of the time. The dispute even became violent and did not end until years after Leibniz's death. His ideas were revolutionary in the field of mathematics due to his ability to solve the contemporary math issues of his time.

__**Alchemy and Chemistry**__ Newton wrote many manuscripts in the field of chemistry. Most of these were just multiple excerpts from different sources put together by him, but a few were his own works. Most of his work in chemistry including an unfinished theory of chemical force was not known by other scientists until a century after his death.
