The beginning of his life

• Born on January 4, 1643

• In Woolsthorpe, Lincolnshire, England

• Where he was raised by his Grandmother

Early life

• Newton received a bachelor’s degree at Trinity College, Cambridge in 1665

• The next two years Newton returned home where he came up with most of his discoveries.

• He returned to Trinity College in 1667, where he became a professor of mathematics in 1669.

Reflecting Telescope

• In 1668 Newton made the first reflecting telescope

• Light is collected and refracted from a curved mirror

• Far superior from refracting telescopes because the image did not become blurry

Calculus

• Newton invented Calculus in 1669, but didn’t publish his work until 1704

• Calculus is divided into two parts Differential and Integral Calculus

• Differential Calculus: Deals with the change in rate of objects

• Integral Calculus: Deals with measuring quantities and dividing into smaller ones

Motion and Gravity

• Newton wondered why objects fell to earth while sitting under an apple tree he saw an apple fall in front of him

• Although many believe this story is untrue

• That is when Newton came up with the three laws of motion

First Law of Motion

• A body continues in a state of rest in a straight line if it is not acted upon by forces.

Second Law of Motion

• When a force acts on a body it produces an acceleration, which is proportional to the magnitude of the force

Third Law of Motion

• If body A exerts a force on body B, body B always exerts an equal and opposite force on body A

Force

• Newton believed that when an object goes around another there are two balanced forces.

• Centripetal force: pulls the revolving object towards the pivoting point

• Centrifugal force: pulls the object away from pivoting point

Comets

• Newton showed that comets acted upon by the same forces as the planets

• Proved when Edmund Halley predicted the next time a comet would pass by again

Principia and Opticks most popular works

• Newton summarized his discoveries in Philosophiae naturalis principia mathematica (mathematical principles of natural philosophy) (1687)

• It shows his principle of universal gravitation and provided an explanation both of falling bodies on the Earth and of the motions of planets, comets and other bodies of the universe.

• Opticks (1704) presented his discoveries of light and elaborated his theory that light is composed of corpuscles, or particles.

A Great Man

• Isaac Newton died on March 31, 1727 in London, England
