Sir Isaac Newton in Godfrey Kneller's 1689 portrait

Sir Isaac Newton (25 December 164220 Mairch 1727 bi the Julian calendar in uiss in Ingland at the time; or 4 Januar 164331 Mairch 1727 bi the Gregorian calendar) wis an Inglish pheesicist, mathematician, astronomer, philosopher an alchemist that wrate the Philosophiae Naturalis Principia Mathematica. In it he descrieved universal gravitation an, throu his laws o motion, laid the foonds for classical mechanics. Newton wis the man that developed the differential calculus an aw daein sae thirty year afore Gottfried Wilhelm Leibniz that aften shares the credit.

Newton wis the first tae mak a set o mathematical laws that coud predeect baith ordinar motion an celestial motion. He is associate wi the scientific revolution an the forder o heliocentrism. Newton is creeditit forby wi providin mathematical substantiation for Kepler's laws o planetary motion. He wad rax thir laws bi shawin that orbits (sic as the orbits o comets) wisna juist elliptic, but coud be hyperbolic an parabolic an aw. He is kenspeckle for his arguments that licht wis componed o particles an aw. He wis the first tae feegur that the spectrum o colour seen whan white licht passes throu a prism is inherent in the white licht an no eikit bi the prism as Roger Bacon haed thocht in the 13t century.

Forby thon Newton developed a law o cuilin, descrievin the rate o cuilin for objects whan exposed ti the air; the hale binomial theorem; an the preenciples o conservation o momentum an angular momentum. Finally, he studied the speed o soond in air, an spak aboot a theory on the oreegin o starns.

Newton's legacy[eedit | eedit soorce]

Newton's laws o motion an gravity gied awbody the foonds for spaein mony sindry scienteefic or ingineerin situations, especially the motion o celestial bodies. His calculus pruived gey important ti the oncome o further scienteefic theories. Finally, he pit mony o the aesome pheesics facts that haed been discovert afore thegither intil a saitisfeein seestem o laws. For this, he is conseidert ane o history's greatest scientists, rankin abuin sic feegurs as Einstein an Gauss.

Quotations anent Newton[eedit | eedit soorce]

"The Principia is pre-eminent above any other production of human genius." —Pierre-Simon Laplace

"Taking mathematics from the beginning of the world to the time when Newton lived, what he has done is much the better part." —Leibniz

"All that has been accomplished in mathematics since his day has been a deductive, formal, and mathematical development of mechanics on the basis of Newton's laws." —Ernst Mach

"Nature and Nature's laws lay hid in night: God said, Let Newton be! and all was light." —poem, Alexander Pope
