ISAAC

NEWTON

Biography.
He was born in England on January 4, 1643. At that time, the calendar in use was the Julian calendar.
and corresponded to December 25, 1642, Christmas Day.4The birth was premature
Apparently, he was born so small that no one thought he would live for very long.
His life was in danger for at least a week. He was baptized on January 1.
January 12, 1643 in the Gregorian calendar.
His parents were Isaac Newton and Hannah Ayscough, two Puritan farmers. No
he came to know his father, for he had died in October 1642. When his mother
She remarried Barnabas Smith, who had no intention of taking on a child.
at three years old, he was left in the care of his grandmother, with whom he lived until her death.
stepfather in1653This was possibly a traumatic event for Isaac; it constituted the
loss of the mother without having known the father. He never dedicated a
loving memory and until his death he went unnoticed. The same happened with the
grandfather, who seemed to not exist until it was discovered that he was also present in
the house reciprocated Newton's affection in the same way: it disinherited him.7

Introduction.-
Isaac NewtonWoolsthorpe, LincolnshireDecember 25, 1642July/ 4 of
Januaryof1643greg.-Kensington, LondonMarch 20JulyMarch 31, 1727greg.) was
aphysical, philosopher, theologian, inventor, alchemistymathematicianEnglish. It is author of
theMathematical Principles of Natural Philosophy, better known as the Principia,
where it describes thelaw of universal gravitationand laid the foundations of themechanics
classicthrough thelawsthat bear their name. Among their other discoveries
scientists highlight the work on the nature of thelightand theoptics(that is
they are mainly presented in their workOpticks) and the development ofmathematical calculation.

Newton shares withGottfried Leibnizthe credit for the development ofintegral calculus and
differential, which he used to formulate his laws of thephysicsIt also contributed in others
 areas of themathematics, developing thebinomial theorem and theformulas of
Newton-Cotes.

Among his scientific findings is the discovery that thespectrum of

colorwhat is observed when white light passes through aprismit is inherent to that light,
instead of coming from the prism (as had been postulated byRoger Baconin the century
XIII); his argumentation on the possibility that light was composed
forparticlesits development of alaw of thermal convectionthat describes the rate of
cooling of objects exposed to air; their studies on thespeed of
soundin the air; and its proposal for a theory about the origin of thestarsIt was
also a pioneer of thefluid mechanics, establishing a law on
theviscosity.

Newton was the first to demonstrate that the natural laws governing the
movement in theEarthand those that govern the movement of celestial bodies are
the same. It is often described as thescientificbiggest of all
times, and his work as the culmination of thescientific revolutionThe mathematician and
mathematical physicistJoseph Louis Lagrange(1736-1813), said that "Newton was the most
great genius that has ever existed and also the luckiest since it can only be
find a system that governs the world.

Newton's laws.
