God's Equation
The Derivation of E=mc2
Perhaps the most famous
equation of all time is E = mc2. The equation is a
direct result of the theory of special relativity, but what does
it mean and how did Einstein find it? In short, the equation
describes how energy and mass are related. Einstein used a brilliant thought experiment to
arrive at this equation, which we will briefly review here.
First of all, let us consider a particle...
