...you need to be able to leave your intuition at the door.
[T]he lecturer derived Schrodinger's Wave Equation from first principles. I can still remember how I felt as everything suddenly became clear to me, I think it was the closest I've even come to a religious experience.
There is a point at which mathematics "clicks" for people who study it and become good at applying it to whatever. It's the point where it stops being a cumbersome, dense, opaque notation and starts describing elementary concepts that really have no other way to talk about them. It goes beyond quantum mechanics. It doesn't "click" for everyone, but that's okay because this phenomenon is not limited to mathematics. I've had the privilege of visiting some of the finest art galleries in the world over decades of life, and Cubism only "clicked" for me last year.
Among some -- but not necessarily all -- of those for whom quantum mechanics never "clicked," there arises a specific belief that because "It's all just mathematics," and that it relies upon the branch of mathematics that quantifies and sets boundaries to uncertainty, there must be no corresponding underlying reality that we can know. That is, they imagine the math(s) can be one thing, and the underlying reality -- whatever it is -- can still be something else that behaves intuitively, and we'll never know what that is. It's a fundamental restatement of the underlying causation principles. Yes, it's more intuitive. It's also wrong.
Physicists definitely don't think this way. But here's the thing: physics students don't think this way either, even the ones who squeaked through Introductory Quantum Mechanics with a C-. The world is full of people who've tried and failed to understand quantum mechanics, just as there are people like me who can't figure out what the hell Picasso is trying to paint a picture of. But the people who make a valiant attempt to understand the subject via formal study, but simply fall short, don't adopt the particular approach we're seeing. As I said: there are characteristic ways of getting things wrong.
No, this particular dismissal of quantum mechanics comes from only once source: woo authors and their intended audience. They like to say they're showing you the holes in the theory, and they like to suggest that physicists and so forth would agree with them if they were being honest. But what they're really doing is a selective and simplified presentation of the subject accompanied by ongoing appeals to sentiments favored by the kind of people who prefer activities in which they were told there would be no math. They whiplash between quantum fields and grand unification. What they want you to come away with is exactly the concept that while Schrodinger and others can quantify a description of the observable behavior of the universe, it's possible -- maybe even likely -- that there's something else entirely different going on under the hood that the description alone can't fathom. They need you to know that physics doesn't know enough to dispute their particular brand of woo.
I'll grant that the shops where you buy these books always smell so very nice. But please don't try to learn physics that way.
