  • Isaac Newton was born prematurely on Christmas day 1642 (4 January 1643, New Style) in Woolsthorpe, a hamlet near Grantham in Lincolnshire. Early years

  • Newton's mother, Hanna returned to Woolsthorpe in 1653 after the death of her second husband, Newton was denied his mother's attention, a possible clue to his complex character.

  • Newton's childhood was anything but happy, and throughout his life he verged on emotional collapse, occasionally falling into violent and vindictive attacks against friend and foe alike.

  • With his mother's return to Woolsthorpe in 1653, Newton was taken from school to fulfill his birthright as a farmer. Happily, he failed in this calling, and returned to King's School at Grantham to prepare for entrance to Trinity College, Cambridge. Learning

  • Since the university was closed for the next two years because of plague, Newton returned to Woolsthorpe in midyear.

  • Education in CambridgeIn 1665 Newton took his bachelor's degreeCambridge without honors or distinction.

  • Newton's laws.In Book III, subtitled theSystem of the World, Newton extended his three laws of motion to the frame of the world, finally demonstrating 'that there is a power of gravity tending to all bodies, proportional to the several quantities of matter which they contain.

  • Newton's masterpiece is divided into three books. Book I of thePrincipiabegins with eight definitions and three axioms, the latter now known as Newton's laws of motion.

  • Newton expressed regret for the algebraic style of recent mathematical progress, preferring the geometrical method of the Classical Greeks, which he regarded as clearer and more rigorous.

    The First Low

  • The Second LawThe change in motion is proportional to the motive force impressed and is made in the direction of the straight line in which that force is impressed (F = ma)

  • The Third LawTo every action there is always an opposed and equal reaction.

  • His last decades were passed in revising his major works, polishing his studies of ancient history, and defending himself against critics, as well as carrying out his official duties.

    Last years

  • He died in London on March 20, 1727 (March 31, New Style).He never married and lived modestly, but was buried with great pomp in Westminster Abbey.
