Einstein didn't said E=mc^2. He actually said E^2 = m^2 c^4 + p^2 c^2, where p is the momentum. The momentum vanishes for particles at rest and we get the famous E=mc^2.

Ahhh very nice...
E2=m2c4+p2c2
If you say p is the momentum we can take p=0 for a mass at rest, right?
This gives us:
E2=m2c4+02c2
Ergo:
E2=m2c4
Take the square root and we got:
E=mc2
Thank you for this really good and inspiring information.
Yep, you got it right! :)
