SCIENTIST WAS BORN ON THIS DAY IN 1643

sir_isaac_newton_01a
Sir Isaac Newton was born on January 4, 1643 in Woolsthorpe, England
and died in London on March 31, 1727.

Physicist and mathematician Sir Isaac Newton became one of the most
influential scientist of all time for formulating the three basic laws of motion
and the law of universal gravitation. He built the first practical reflecting
telescope and his work helped Enlightenment thinkers rebel against
Church theology. Newton’s mother wanted him to be a farmer, but the
headmaster of King’s School, Henry Stokes, convinced her to let him
complete his education.
