It is the most easily remembered part of Einstein's Special Theory of Relativity, which disproved the gravitational works of Issac Newton.

A re-writing of Einsteins famous equation is E = mc2 Wherre E is energy, m is mass, c is the speed of light (so c2 is the square of the speed of light)
Experiments carried out so far confirm the formula.
It relates the energy of a particle to it's mass. So, if you were to convert 1kg of material into pure energy, the energy you would get out would be calculated using E = mc2.However, this is just the simplified version for a particle that isn't moving. If the particle is moving with a momentum p, then the full formula is used: E2 = p2c2 + m2c4.
1905 was when the paper about it was published. So he probably discovered it a few years earlier? There doesn't seem to be an exact date or anything.
The 2 stands for squared . So in all the formula is : Energy equals the mass times the constant (Speed of light) squared. The 2 squares the formula.
