If the Schroedinger equation and the things related to it define the microscopic world, what that means is that the shape of nature is simply that way, and the mystery is not that it is that way, but that the larger world is not also that way. And the answer to that question is that the quantum physics, when aggregated into classical magnitudes, simplifies down into classical behavior, but that the universe at its most fundametal level is not classical.
Why it is quantized
When a pure sound of specific frequency f hits a diapason with own frequency f, it resonates. Let's suppose we still hadn't found an explanation of it, we could say: "That's the way the world is!".
I know that quantization could never been explained, but it would seem very strange to me.
You can say: "world doesn't have to behave in a classical way!" Ok, but i still have to see in a book of physics a better classical study of the interaction between a light beam and an electron.
I say this because you cannot say: "an electromagnetic wave interacting classically with a point of charge, or a little sphere of charge, doesn't provide the right solution of what happens". Thanks! The electron is not a point or a sphere or anything like this! NOW, we know it! So we are not forced to think with quantum mechanics theory (from which, for example, h is a postulate, it's not explained), to study classically the light-electron interaction.
For example, if the electron were a wave of charge, (it's just an example, I don't have believes on it), how would an electr.magn. wave interact, classically, with it? I mean, classicaly in the sense without quantum mechanics, but with special relativity of course.
I'm aware it wouldn't be a simple problem, every charged region of that space would move according to sp.relat. and would produce others electr.magn. waves ecc. Are we sure in this case the interaction would be the same as it is in the normal classical way?
