Organization: Cheap Astronomy

Description:

Read by Duranee and Barry Haworth, written by Steve Nerlich, technical advice from Stephen D’Souza.

A relatively good episode…

E=mc^2

E=mc squared is a nice straight-forward formula, indeed the energy-mass equivalence concept that underlies it is pretty straight-forward too. So, part of its popularity as the world’s most famous physics formula is that everyone kind-of gets it – energy equals mass times a constant – well OK a constant squared, but that is still a constant. But why is that constant a velocity – and why is it squared?
