Sir Isaac Newton
Born on Christmas day in 1642, Sir Isaac Newton was the first modern scientist. His uncle had told his mother that he had an 'extraordinary talent'. Isaac was sent to the Cambridge University in 1661 to study mathematics. In 1665 when Isaac got his degree, he returned to his mother's house to get away from an outbreak of the Great Plague. He discovered many things that scientists all over the world use today. Isaac discovered that a beam of sunlight contains all the colours of the rainbow by shining the light through a glass prism. He also invented the first reflective telescope, which out-classed most other telescopes because it had incredibly great views that wern't blurry. While he was at his mother's, one day he saw an apple fall from a tree and he began to think about what made things fall, which lead to the theory of gravitation. Isaac also thought about how the planets move around the sun. He came up with the three laws of physics-
1. Objects that are moving at a constant speed will not change speed unless there is a force acting on it for example, if you push a shopping trolley and let it go it should keep going until it crashes into something, hopfully the vegetables, but friction from the ground slows it down.
2. The more powerful and light something is, the faster it will accelerate for example, a cyclist will accelerate much faster than a ten-tonne truck
3. Every action has an equal and opposite reaction for example, when a rocket fires, it pushes itself up and away from Earth.
Isaac's laws are still incorporated in science today. In 1667 he returned to Cambridge and two years later he became the Lucasian Professor of Mathematics.This brilliant man also wrote a book called Principia that was published in 1687. It showed how his laws could explain movement of the sun and the other planets and the motion of things on Earth. On the 20th of March 1727, he died.
