What are the things that Sir Isaac Newton invented?
Isaac Newton explained the workings of the universe through mathematics. He formulated laws of motion and gravitation. These laws are math formulas that explain how objects move when a force acts on them. Isaac published his most famous book, Principia, in 1687 while he was a mathematics professor at Trinity College, Cambridge. In the Principia, Isaac explained three basic laws that govern the way objects move. He then described his idea, or theory, about gravity. Gravity is the force that causes things to fall down. If a pencil falls off a desk, it will land on the floor, not the ceiling. In his book Isaac also used his laws to show that the planets revolve around the suns in orbits that are oval, not round. Isaac Newton used three laws to explain the way objects move. They are often call Newton’s Laws. The First Law states that an object that is not being pushed or pulled by some force will stay still, or will keep moving in a straight line at a steady speed. It is easy to understand
Newton was primarily what we would call today a theoretical physicist, which means he came up with theories as to how the universe works, rather than specific practical inventions. These were primarily his three laws of motion and the law of universal gravitation. The only real invention of his I can think of is the Newtonian telescope, which solved the problem of chromatic aberration in the telescopes of his day, all of them refractors. He made a working model, but it was very small and the idea really wasn’t developed further until long after his death. I suppose you could say that he invented mathematical techniques, notably calculus, but this is not something you could put a patent on.
