> Quantum mechanics is simple, but baffling to beginners Quantum mechanics is weird to us because we're human-sized and quantum effects are mostly gone at our scale. Therefore, the only language we have for actually doing quantum mechanics is mathematics, so it makes sense to get a firm grasp of the math first. Fortunately, the fundamentals of the math aren't that difficult. I like to think of quantum mechanics as being 'mind-bendingly simple' for that reason. Scott Aaronson has a fascinating lecture on quantum mechanics seen as a branch of probability theory: http://www.scottaaronson.com/democritus/lec9.html http://www.scottaaronson.com/democritus/lec9.html > Quantum mechanics is what you would inevitably come up with if you started from probability theory, and then said, let's try to generalize it so that the numbers we used to call "probabilities" can be negative numbers.
