Albert Einstein is best known for his Theories of Relativity. He has been acknowledged as one of the greatest scientists in human history.

While working as a clerk in Switzerland, Einstein produced the Special Theory of Relativity. This theory states that mass, length and time changes, depending on how a person looks at it.
In 1915, Einstein published his General Theory of Relativity. This new theory created a controversy because many scientists did not agree with him.
