  3. The beginning of his life • Born on January 4, 1643 • In Woolsthorpe, Lincolnshire, England • Where he was raised by his Grandmother Woolsthorpe Manor: house where Newton grew up

  4. 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.

  5. 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

  6. 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

  7. 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

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

  9. Second Law of Motion • When a force acts on a body it produces an acceleration, which is proportional to the magnitude of the force

  10. 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

  11. 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

  12. 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

  13. 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.

  14. A Great Man • Isaac Newton died on March 31, 1727 in London, England

  15. References • Book • Isaac Newton (The Last Sorcerer), by Michael White • Encyclopedia Article • The New Encyclopedia Britannica Volume 8.
