I have not formally studied physics but am interested in quantum physics. I have studied calculus so I know a little bit about mathematics in case the answer requires it. My question is, when a physicist conducts experiments at the quantum level, how do they know that what they are "seeing" is...

Thanks! I have just recently started to think about this and really don't know much. Also, I have not taken any formal classes in physics so ...

In Einstein's famous equation, why did he use the speed of light squared? Why not some other constant?

I am interested in math and physics and have questions.
