Default What's the energy got to do with the speed of light?

Hi everybody,

I have a question which bothers me since long time and maybe with your help
I can find the answer at last. Since I heard the formule E=mc^2 for the
first time it struck me that there seems to be no logical relation between
the energy contained in a mass and the speed of light.

1) Screw your fat stupid ass into a chair.
2) http://www.****inggoogleit.com/
3) E^2 = p^2m^2 + m^2c^4
4) \int^c_0{P dv}

where P = mv\gamma
\gamma = \frac{1}{\sqrt{1 - (\frac{v}{c})^2}}

\int^c_0 {\frac{mv}{\sqrt{1 - (\frac{v}{c})^2}} dv = mc^2

5) Awww... monkey-boy doesn't speak LaTeX?

The integral from zero to c of [(momentum)dv]

where momentum = (mass)(velocity)(gamma)
gamma = 1/sqrt[1 - (v^2)/(c^2)]

6) Was that so hard? For the slow of thinking,

American Journal of Physics 58(4) 348-349 (1990)
E=mc^2 derived from 19th century physics
