# Derivation of E=Mc2? For the common man

• B

Ok this is perhaps the single most famous equation known to man. And I have basically zero idea how it came to be. I have a slight background in classical physics (a couple college classes)

I know it states that energy is equal to mass multiplied by the speed of light squared.

I have tried to read online postings on it but have been unable to follow.

So is it possible to get a step by step derivation of this equation so that even a lay person could understand it?
