according to the theory of relativity since we're supplying it with energy when it's already travelling at te speedd of light?
you can mail me at tut_einstein@yahoo.com
i also need some help in the basics of thermodynamics, and i'm not familiar with calculus. so it's a prob. cud someone help me?

Electrons have mass. They don't move at c.

"Electrons revolve at the speed of light"
That statement is wrong in at least two ways.
1 - electrons do not move at the speed of light
2 - they don't 'revolve' around the nucleus of the atom in the same way that planets orbit a star. Whilst they can be said to occupy 'orbits', these are quantum mechanically calculated statistical probabilities regarding the electron's postion.
Only one thing needs to be said about thermodynamics. It's TdS

(1) electrons do NOT revolve around the nucleus. This is a simple model that is used to help students understand in lower classes. But it is NOT correct. It is more like electrons hover / fluctuate in a region very roughly shaped like a shell (but this can vary quite a bit, look under "electronic orbitals" on the web)
(2) electrons certainly do NOT revolve at the speed of light. For one, if they did then their relativistic mass would be infinite (since they have a mass at rest)
sorry to disappoint you ;-)

You already got your answer. Electrons move at the speed of the order of 1/100 times that of light.
