If you <i>really</i> want to understand quantum mechanics in an intuitive sense (i.e. enough to understand why it works, but not really enough to generate your own robust predictions at a very granular level) I recommend <a href="http:&#x2F;&#x2F;lesswrong.com&#x2F;lw&#x2F;r5&#x2F;the_quantum_physics_sequence&#x2F;" rel="nofollow">http:&#x2F;&#x2F;lesswrong.com&#x2F;lw&#x2F;r5&#x2F;the_quantum_physics_sequence&#x2F;</a><p>There is a (subtly, and not in a terribly important way) flawed conclusion regarding personal identity toward the end, and parts of it are a bit long-winded (I guess esp if you don&#x27;t already enjoy reading Yudkowsky as I do), but it is solid.<p>tl;dr: QM&#x27;s reputation is more a function of it being poorly taught (cf this article), not really the theory itself - ultimately it makes the world <i>less</i> confusing, as any sound scientific theory should.
