Even then, I wouldn't say finding the probability directly is the emphasis in a quantum mechanics course; the emphasis is finding the socalled probability amplitude, whose norm squared is related to a PDF. My thought was rather that such an approach could be constructed, not that I've seen one. The foundational maths of quantum mechanics predate quantum mechanics  they're what happen when you generalise probability from real numbers to complex numbers. ...

But whatever; I'm honestly not sure how seriously the image is supposed to be taken given the last panel. I gave that one a pass because it's at least obtainable as the classical limit of quantum results... ... this is my signature!

RE: Quantum Physics
I would recommend the works of Deepak Chopra!!! He has a very good understanding of quantum physics.
Had you worried there for a second, eh? Another question I would ask is "what time frame are you looking at?" If you want a deep understanding, you might and probably should be thinking in terms of years. Maybe 2 or 3 or 4. Nothing wrong with that. You mention linear algebra and stats, but a good bite at calculus (including DEs and maybe tensor calculus) would be invaluable. If you're looking at a much shorter time frame, there are a number of excellent recommendations in this thread. And, of course, you can do both. Read some of the less technically difficult sources now and then move onto the more advanced stuff later. Best of luck.

I intend it to be a lifelong study, so I am starting with the very basics and working my way up (or down?)

RE: Quantum Physics
Edx offers some great free courses online https://www.edx.org/course?search_query=Quantum
Also the Feynman lectures are wonderful. I only wish I had the advanced math background one needs to truly understand the beauty of this strange language... "Only two things are infinite, the universe and human stupidity, and I'm not sure about the former." Albert Einstein

I'm learning about the various types of quarks, antiquarks and gluons that form hadrons. It was interesting to learn that proton particles, despite being seen as having two up quarks and one down quark actually have zillions of quarks and antiquarks and gluons dashing around at near the speed of light and smashing into each other. I think next I will learn about how gluons act as carriers of energy in terms of gravitational and electromagnetic forces. Well, that is only if you take a top/down approach.

You guys can shove these quark jokes up your bottom.

RE: Quantum Physics
But there's such truth and beauty in them...

RE: Quantum Physics
Truth and beauty are things of the past, my friend. Physics got ugly.
