Albert Einstein is best known for his Theories of Relativity. He has been acknowledged as one of the greatest scientists in human history.
Born in Germany in 1879, Einstein did poorly in all his school subjects, with the exception of Mathematics, which was his favourite subject.
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.
In the end, some simple experiments proved Einstein to be correct. Einstein was awarded the Nobel Prize for his work in physics.
