If you have found quantum mechanics a bit difficult to grasp do not worry too much. You have good company. Schrodniger was never comfortable with quantum jumps all his life. He thought one could go back to classical wave theory in some way.
Here is a quote from Max Jammer's book, p324.
Finally, when Bohr referred even to Einstein's paper3 of 1916 (or 1917) on the transitionprobabilities as supporting his view that without such discontinuities Planck's radiation law could not be accounted for, Schrodinger reportedly exclaimed:
"If one has to stick to this damned quantum jumping, then I regret having ever been involved in this thing";
whereupon Bohr replied:
"But we others are very grateful to you that you were, since your workdid so much to promote this theory."
