Newton and the apple

When scientist and polymath, Isaac Newton famously said “if I have seen further it is by standing on the shoulders of giants“, one of the giants he was referring to was Galileo.

Newton (1643-1727), who emerged as one of the greatest minds of the 17th century, discovered the laws of motion and described gravity.

A century earlier Galileo proved that objects fall at the same speed regardless of their mass. Newton understood that this phenomenon also worked in space and used mathematics to prove that the whole universe is governed by the same laws of physics. Gravity effects a falling apple in the same way as it effects an orbiting planet.
