Isaac Newton

On December 25, 1642, Newton was born in Ulsthorpe, a small village in England. Newton lost his father at an early age and was dependent on his mother. He entered trinity college, Cambridge, in 1661.

Between 1665 and 1667, Newton was already thinking about gravity. One evening, he was sitting under the apple tree, enjoying the cold. An apple fell from the tree. It occurred to him: why did the apple fall only to the ground and not to the sky? He analyzed Copernicus's heliocentric theory and Kepler's three laws, and then thought: why do the planets keep moving around the sun? Why are planets so fast when they are close to the sun and so slow when they are far away? Why are planets orbiting farther away from the sun longer? Newton found The Law Of Attraction.

Isaac Newton, the great British physicists, mathematicians, scientists, thinkers and philosophers, and at the same time he was also an enthusiast of Britain alchemy. He proposed the law of gravity in the Philosophiae Naturalis Principia Mathematica published on July 5, 1687. Newton's law of motion forms the foundation of classical mechanics, and he imagined space and time as some invisible matrix through which we pass without changing them. Newton and leibniz independently invented calculus. In mechanics, Newton explained the principle of conservation of momentum and angular momentum. In optics, he invented the reflection telescope and developed the color theory based on the observation that white light is emitted by a prism into a visible spectrum. He also formulated the cooling laws and studied the speed of sound. He left over half a million words of alchemy and more than a million words of his works. He is recognized as one of the greatest and most influential scientists in human history.
