He wasn’t expected to live beyond the first day of his birth — he was born premature. Yet, he lived to 84, and etched his name in history. Sir Isaac Newton was an English mathematician, physicist, astronomer, theologian, and author who is widely recognised as one of the most influential scientists of all time, and a key figure in the scientific revolution.


Childhood

Newton was born in Woolsthorpe, England on January 4, 1643. His father, a farmer, died three months before his birth. His mother remarried when Newton was three, and left young Isaac in the care of his grandparents.


His mother tried to take him out of school so he could help on the farm, but he had no interest in becoming a farmer and was soon back at school. He grew up mostly alone. For the remainder of his life, he preferred to work and live alone.

Important discoveries

Reflecting telescope – This type of telescope uses mirrors to reflect light and form an image. Nearly all of the major telescopes used in astronomy today are reflecting telescopes

Some of the most important and famous ones include:


Gravity – Newton is probably most famous for discovering gravity. Outlined in the Principia, his theory about gravity helped explain the movements of the planets and the Sun. This theory is known today as Newton’s law of universal gravitation.

Laws of Motion – There are three fundamental laws of physics that laid the foundation for classical mechanics.

Calculus – Newton invented a whole new type of mathematics which he called “fluxions.” Today, it is referred to as calculus, and is used in advanced engineering and science.
