Isaac Newton’s first interest in science was when he was a young boy. He watched his father’s work as an astronomer and he loved to study nature.

As a young man, Isaac Newton wrote papers on optics and mathematics. He also did experiments on light and color.

In 1666, when the Great Fire of London destroyed much of the city, Isaac Newton discovered that white light is made up of all the colors of the rainbow. This was one of his most important discoveries about light.

Newton went on to make many other discoveries about the laws of physics, such as gravity, which he called his greatest discovery. He also invented calculus and discovered ways for people to communicate with each other faster than ever before by sending messages through space using telescopes called reflecting telescopes or reflecting mirrors.
