Isaac Newton

Isaac Newton was born in 1642. His mother wanted him to become a farmer, but his uncle uncovered his scholarly talents. Isaac attended Trinity College in Cambridge. When he was in his mid twenties, he invented the reflecting telescope, which is the building block of all telescopes today. He then invented calculus an important part of mathematics, and which is used in science. He then helped clarify the three laws of motion. In addition he developed the law of universal gravitation. He discovered that the force that keeps us on earth is the same force that allows the planets to orbit the sun. He correctly hypothesized the idea that gravity is throughout the universe. Isaac Newton was instrumental in the development of the science community that we have today. He was named Lucasian Professor of Mathematics at Cambridge University. Isaac Newton died in 1727.


Newton's three laws of motion:

• Law 1 - An object moving in a straight line will continue moving in a straight line, unless acted on by an outside force. Also, an object at rest will stay at rest. The word for this is inertia.


• Law 2 - Force will cause a change in the motion of an object. The change in motion depends on the amount of force and the mass of the object. There is a formula for this F=ma (force equals mass times acceleration).


• Law 3 - For each action, there is an equal and opposite reaction.
