### Famous Scientist Research Project

## Childhood & Early Life

Isaac Newton was born prematurely on Christmas Day in 1642, in Woolsthorpe, Lincolnshire. His father died 3 months prior to his birth.H is mother, Hanna, went on to get remarried and raise another family. Isaac's Grandmother was then responsible for him. Newton and his mother's relationship wasn't that great. She returned later on in Newton's life to have him pursue his calling in farming, but obviously that wasn't it. Isaac studied at Cambridge after he left Woolsthorpe. He struggled in school also, but he learned to master other studies of Science & Mathematics.

## Interest in Science

Newton's interest in Science came about after he received his bachelors degree at the University of Cambridge. During the plague years, Isaac spent 18 months studying and making contributions to Science and Math. He felt like he was in his prime for inventing and sharing his knowledge. Newton invented calculus to prove his theories. He made new discoveries about light and gravity.

## Hardships Faced During Scientific Career

Gottfried Leibniz and Newton were said to both create calculus. Over many years the two of them were both accused for stealing each others ideas in calculus. Another set back was when Robert Hooke questioned Newtons ideas and discoveries which in return damaged his confidence and discouraged him. More set backs occurred when King James II said that teachers must be forced to be a Church of England minister after seven years. Newton was opposed to this idea. Throughout his career Newton faced different hardships.

## Major Experiment & Contributions

Sir Isaac Newton had many contributions to science, that is why he is known as the "Father of Modern Science" or the "Father of Physics". Some of his contributions include the reflecting telescope, discovering calculus and chemistry, three laws of motion and laws of universal gravitation.

The telescope prior to newtons discovery was not ideal. the telescope was often out of focus and hard to use, newton solved this problem by using mirrors instead of lens. His original telescope was built himself in 1668, which was six inches long. this newly remolded telescope magnified whatever it focused on by 40 times.

Newton began to notice the problems of the motion of the planets an what kept them in their orbits around the sun, since they had continuous change. So, he invented another part of mathematics, which he called calculus. Calculus allowed Newton to draw tangents to curves, measure lengths of curves, and solve other problems that geometry couldn't solve.

The three laws of motion, the laws explain how the universe works and gives principles of space and time. the first law is *Law of inertia:* Every object persists in its state of rest or uniform motion in a straight line unless it is compelled to change that state by forces impressed upon it. The second law is *Law of acceleration: *Force is equal to the change in momentum (mV) per change in time. For a constant mass, force equals mass times acceleration, *F = ma*. The third law is *Law of action and reaction: *For every action, there is an equal and opposite reaction.
