It seems that the energy expectation value is independent of time.(adsbygoogle = window.adsbygoogle || []).push({});

I did it for an infinite square well. And when you time evolve your wave function

the time evolution cancels when you complex conjugate it and then do the integral.

<E>=<ψ|E|ψ> it seem like this might always independent of time, What do you guys think.

I guess I could try to prove it in general.
