Who was Isaac Newton?

January 4,1643 - March 1,1727

Isaac Newton was a famous mathematician and English physicist who contributed to the start of the scientific revolution by creating the 3 laws of motion and other contributions. His book Principia laid the foundation of classical mechanics. He also developed calculus with the help of Gottfried Leibniz and built the first working reflecting telescope. Isaac Newton was best known for explaining how gravity works ad making us understand how to relate to the world around us.

FIRST LAW OF MOTION

An object in motion will stay in motion unless acted upon by an unbalanced force and an object at rest will stay at rest unless acted upon by an unbalanced force.

SECOND LAW OF MOTION

The acceleration of an object is proportional to the force acting on it and inversely proportional to it's mass.

THIRD LAW OF MOTIO

(law of equal and opposite force)

For every action there is an equal and opposite reaction.

Isaac's invention of the reflective telescope

Isaac was not the first person to invent a telescope, but in 1668 he did successfully build a reflective telescope that did not suffer from chromatic aberration.
