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.

I gave that one a pass because it's at least obtainable as the classical limit of quantum results...

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? Evil_monsterSmile

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.

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

The image was not meant to be serious in any way

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...

I'm learning about the various types of quarks, anti-quarks 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 anti-quarks 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 electro-magnetic forces.

Well, that is only if you take a top/down approach.

You guys can shove these quark jokes up your bottom.

Truth and beauty are things of the past, my friend. Physics got ugly. Tongue

That quark joke was weak . . . Tongue
