Very much so. The incorrect ones never became famous.

He made Einsteins theory of relativity "Beautifull". He proved Einsteins original and not his revised theory of relativity was indeed correct. But most of all, he is an amaising person!

### Can you weigh energy?

This is a tricky question. Quantum mechanicss shows us that all energy can be turned into mass and all mass into energy. To work out the equivilant mass of an amount of energy (or vice versa) simply use einsteins famous equation E= mc^2 - rearrange m = E/c^2 I do not know of any device that can directly "weigh energy".

### What is Einsteins famous equation E equals mc2 what does it calculate?

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.
