And you can do quantum mechanics without the wave function, in fact Heisenberg came out with a way to do that about 6 months before Schrodinger discovered his wave function; they both give the same answers but in most situations Schrodinger way is easier to use. * *If you dislike the wave function you'll really hate Heisenberg method, its even more abstract and Heisenberg took pride over the fact its completely un-visualizable; you input some measured values into Heisenberg's mathematical machinery and it outputs the probability of getting other measured values And Heisenberg doesn't treat variables that haven't been measured as having a unknown value, he treats them as having no value at all.
