"Not everything that counts can be counted, and not everything that can be counted counts."
Albert Einstein is a very important figure in the field of Physics. He lived from 1879 to 1955, and within this period of time contributed so much to the field of Physics that he has been named as the "Father of Modern Physics".

His discoveries and research about special relativity and general relativity laid the groundworks for physics today. In the year 1921, he even won a Nobel Prize in Physics for "his services to Theoretical Physics".



Einstein was a hardworking individual who aspired to work and improve of the theories of Isaac Newton.

His efforts eventually paid off in 1905 when he published a paper which proposes the **Theory of Relativity**. This special Theory of Relativity was based on two main postulates:
 * 1) The speed of light is constant for all observers.
 * 2) Observers moving at constant speeds should be subjected to the same physical laws.

And by following this logic, Einstein hypothised that space and time are relative, not absolute, and further proved in the very same year, that mass and energy are related by the equation: //**E = mc2**//



In this equation: //**E = mc2**//, **//E//** represents energy, **//m//** represents mass, and **//c//2** is the speed of light squared, or multiplied by itself. This equation basically means that as the speed of light is a very large number and when is multiplied by itself, it shows how a small amount of matter can release a huge amount of energy.

It was with the help of this equation which enabled the development of nuclear physics, which has brought much needed energy to the world of today.
