## Newton's Scientific Contributions

*Newton's Three Laws of Motions:*

Isaac Newton came up with three basic ideas that are applied to the physics of most motion. The ideas that he has developed have been tested and verified numerous times over the years and these ideas are now called Newton's Three Laws of Motions. The three laws are:

- The law of inertia
- F=ma
- For every action there is an equal and opposite re-action. [Click here for more]

*Discovering Gravity:*

There is a popular story that Newton was sitting under an apple tree when an apple fell on his head, which triggered the idea of the Universal Law of gravitation. However, the apple incident is only a minor part of the effort and the inspiration that lead to the discovery of gravity, because in reality what he discovered was that there is an external force is required to change the speed or direction of a moving object, and further experimentation led to the theories of gravity.

*Optics:*

Newton used prisms to shows that sunlight was made up of the different colours of the rainbow, hence, proving the Ancient Greek's ideas about light wrong. It had been thought that colour was created by mixing light and dark, however, Newton noted that blended print on a white page appears grey and not coloured when viewed from a distance. This led him to bending light through prisms, which led to the discovery of the existence of a mixture of distinct coloured rays in white light.

*Newton's Mathematical Discoveries:*

Newton came up with the Binomial Theorem and was one of the two founders of calculus. These discoveries played a role in the fundamental leap in the field of maths and science which allows calculations to be more accurately modeled on the behaviour of the universe. Many of Newton's discoveries are now common knowledge today but was revolutionary at the time. By developing this new form of mathematics, it became possible to accurately calculate the area inside a shape with curved sides. [Click here for more]
