Sir Isaac Newton

『By Cassandra Davis』


Named after his father, Sir Isaac Newton—who was born December 25, 1642 and died on March 20, 1726—was a was an English physicist and mathematician who is widely recognized as one of the most influential scientists of all time and as a key figure in the scientific revolution.

【Early Life】

Isaac Newton was born according to the Julian calendar—which was what they used in England at the time—on Christmas Day, 25 December of the year 1642 at Woolsthorpe Manor in Woolsthorpe-by-Colsterworth, a hamlet in the county of Lincolnshire.

From the age of about twelve until he was the age of seventeen, Newton was educated at The King's School, Grantham which taught him Latin but no mathematics. He was removed from school, and by October 1659, he was to be found at Woolsthorpe-by-Colsterworth, where his mother, widowed for a second time, attempted to make a farmer of him. Henry Stokes, master at the King's School, persuaded his mother to send him back to school so that he might complete his education.

In the year of 1661—during the month of June—he had gotten accepted Trinity College, Cambridge, on the recommendation of his uncle Rev William Ayscough. He started as a subsizar—paying his way by performing valet's duties—until he was awarded a scholarship in 1664, which guaranteed him four more years until he would get his M.A.


After he attended collage, Sir Isaac Newton became a physicist and mathematician. Other occupations include astronomer, philosopher, alchemist and theologian. The reason he wanted to become a scientist is because back at the University of Cambridge, people began to recognize his scientific ability. In 1669, at the young age of 27, he became a professor of mathematics there. After 20 years of giving and lectures as well as working on his ideas for mathematics and physics.

Many scientist had admired his work. One of them was Edmond Halley, who was an important astronomer. Halley was the one who inspired Newton to write up his work and publish it for the world to see.

【Universal Law of Gravitation】

This law states any two bodies in the Universe attract each other with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

The way Sir Isaac Newton figured out the equation was by witnessing an apple fall from an apple tree. It was then Isaac though that the apple is accelerated, since its velocity changes from zero as it is hanging on the tree and moves toward the ground. Thus, by Newton's 2nd Law there must be a force that had an effect on the apple to cause this acceleration. Let's call this force "gravity", and the associated acceleration the "acceleration due to gravity".

【Changing History】

The way Isaac changed history was by creating the laws of gravity; the universal law of gravitation. This explains the law of gravity, how it works, and Isaac even created an equation. F = Gm1m2/r2

The gravity formula is given by Where, G is a constant equal to 6.67 ×× 10-11 N-m2/kg2, m1 = mass of the body 1, m2 = mass of body 2, r = radius or distance between the two bodies.

This famous scientist made the world change in a good way; without understanding the force of gravity, we would have no clue why we are staying on earth and not float away into space.


How was Isaac Newton revolutionary? Newton's work was the capstone of the Scientific Revolution, utilizing the advances made before him in mathematics, astronomy, and physics to derive a comprehensive understanding of the physical world.
