How to learn quantum physics?

This is a collection of lectures on quantum mechanics given by Professor Leonard Susskind, which emphasize the fundamentals of quantum physics. http://www.infocobuild.com/education/audio-video-courses/physics/quantum-mechanics-winter2012-stanford.html

You are trying to make sense of something that does not make sense. “By 1928 or so, many of the mathematical formulas and rules of quantum mechanics had been put in place and, ever since, it has been used to make the most precise and successful numerical predictions in the history of science. But in a real sense those who use QM find themselves following rules and formulas laid down by the ‘Founding Fathers’ of the theory…. Without really understanding why the procedures work or what they really mean. …. What are we to make of all this? Does it mean that on a microscopic level the universe operated in ways so obscure and unfamiliar that the human mind, evolved over eons with phenomena on familiar everyday scales, is unable to fully grasp what really goes on? Or, might it mean that through historical accident physicists have constructed an extremely awkward formulation of QM that, although quantitatively successful, obfuscates the true nature of reality? No one knows.” – Brian Greene, The Elegant Universe 'I think it is safe to say that no one understands quantum mechanics'. Richard Feynman If anyone understood QM it would be Richard Feynman Who needs fantasy, when they have Quantum Mechanics - Me I find the best way to approach QM is: QM is like going to see a fantasy movie (Harry Potter, Twilight, Lord of the Rings, Underworld, etc). Though the movie involves a universe that has different rules from the universe we live in, we have no problem accepting witches, warlocks, hobbits, werewolves, vampires. We learn the rules and the movie makes perfect sense. (Quick: If you saw a person that sparkles in sunlight what is he or she? I bet you could answer without thinking about it. Though you know that people do not sparkle in sunlight. You know the rule, accept the rule, and apply the rule.) The thing about QM is, QM is real. The rules describe the sub-atomic world accurately. The rules are consistent and rational, BUT they are also illogical and counter intuitive. We must accept (like the movie) that the rules make sense in that world, even though that make no sense in the macro world of things larger than an atom. We do not “understand” QM, we “Interpret” it. We form mental pictures of what is going on and they are weird because QM is weird. The Interpretations may not be “reality.” Copenhagen is just one of those Interpretations. We use the Interpretation that best fits the phenomena we are trying to analyze. So, don't try to understand it. No body does. Learn the Rules (A couple of the more common Interpretations.) I Recommend: Copenhagen, Wave-Particle Duality, Probability Wave, and Many Worlds. These are all weird views of Reality and though they work very well and give very accurate predictions of how the universe works, as Greene says, they may not be what is really going on. Then review the Classic QM Experiments and see how the Interpretations explain the results. I recommend: 2 Slit Experiment Delayed Choice Experiment Quantum Eraser You do not need any math for that. The detail work like the location and spacing of the Interference Fringes can come later when you have the math and physics skills. The important thing for you now is to get comfortable with the weirdness and counterintuitive nature of QM.
