Well, first of all, I have a questions. I’m working through the derivation of Schrondinger’s equations, and I was able to come up with the correct solution, but I’m stuck on the interpretation of one of the terms. In one of the earlier steps in deriving it, the wave function is being operated on by the Laplacian. I’m have a tough time understanding what the physical interpretation of that would be. Wave functions describe probability amplitudes of the electron location as a function of x and t, but applying the Laplacian doesn’t make sense to me. Can anyone help with this dilemma?
