Newton was born on January 4, 1643, in Woolsthorpe, England. Isaac Newton is acknowledge as a genius physicist and mathematician, and is credited as one of the great minds of the 17th century (Scientific Revolution). His discoveries include in fields such as optics, motion and mathematics< as well as the development the principles of modern physics. In 1687, he published his most acclaimed work, Mathematical Principles of Natural Philosophy, which has been called the single most influential book on physics. Newton died in London on March 31, 1727.
Gravity theory
“Gravity really does exist,” Newton stated in 1687. It acts according to the laws which we have explained, and abundantly serves to account for all the motions of the celestial bodies.” His gravity theory was Mathematical Principles of Natural Philosophy, published 5 July 1687. In it, Newton stated that gravity as an ever-present force, a tug that all objects exert on nearby objects. The more mass an object has, the stronger its tug. Increasing the distance between two objects weakens the attraction.
Under most conditions Newton's three laws and his theory of gravitation are adequate. With his equations, Newton was able to explain for the first time why the Moon stays in orbit around Earth. To this day, we use Newton’s math to predict the trajectory of a softball toss or of astronauts landing on the Moon. In fact, all everyday observations of gravity on Earth and in the heavens can be explained with Newton’s theory.
