When was isaac newton born

Sir Isaac Newton is best known for his work on gravity. He also worked on and discovered many other scientific wonders during his lifetime (1642-1727). His work in physics was so advanced that he was the first scientist to be knighted, which is a great honor in England and the reason "Sir" preceeds his name.

He is one of the few acknowledged geniuses in the history of science. There is argument about who qualifies beyond he and Einstein, to a greater or lesser degree, but not about these top 2.

Newton was a polymath too, an all-round genius. He is responsible for
- the laws of motion
- the law of universal gravitation
- proving Kepler's Laws of Planetary Motion
- the first theory of colour and spectrum
- the first practical reflecting telescope
- jointly with Leibniz, the mathematical calculus

He was famous in his own time, but was not always an attractive person, being sometimes cranky, argumentative and ungenerous.

Lagrange said Newton amongst scientists was "the most fortunate, for we cannot find more than once a system of the world to establish."

Isaac Newton was born on 25 December 1642.

25 December 1642.

No.

A vast number of things, eg the laws of motion. Specifically, he constructed the first practical reflecting telescope.

Sir Isaac Newton was a scientist. One of his main contribution to the science society was the discovery of gravity. majority of his contribution were into classical mechanics.

25 December 1642 [NS: 4 January 1643]
During Newton's lifetime, two calendars were in use in Europe: the Julian ("Old Style") calendar in protestant and Orthodox regions, including Britain; and the Gregorian ("New Style") calendar in Roman Catholic Europe. At Newton's birth, Gregorian dates were ten days ahead of Julian dates: thus his birth is recorded as taking place on 25 December 1642 Old Style, but can be converted to a New Style (modern) date of 4 January 1643. By the time of his death, the difference between the calendars had increased to eleven days: moreover, he died in the period after the start of the New Style year on 1 January, but before that of the Old Style new year on 25 March. His death occurred on 20 March 1726 according to the Old Style calendar, but the year is usually adjusted to 1727. A full conversion to New Style gives the date 31 March 1727.

Isaac Newton discovered the Law Of Gravity. You can check more about Law of Gravity here... (click here).
