An extremely intelligent friend of mine who is studying physics as an undergraduate read the quantum physics sequence for me. He said that it's an alright explanation of the physics, in an extremely qualitative way. He said that he would personally prefer to learn QM properly via a textbook with more math.

He says that the argument given for many-worlds is valid iff you're a scientific realist, which not all scientists are.

Even then it's not obvious that it's the best explanation. Also depends on what you mean by 'realist'.

How accurate is the quantum physics sequence?

Prompted by Mitchell Porter, I asked on Physics StackExchange about the accuracy of the physics in the Quantum Physics sequence:

What errors would one learn from Eliezer Yudkowsky's introduction to quantum physics?

Eliezer Yudkowsky wrote an introduction to quantum physics from a strictly realist standpoint. However, he has no qualifications in the subject and it is not his specialty. Does it paint an accurate picture overall? What mistaken ideas about QM might someone who read only this introduction come away with?

I've had some interesting answers so far, including one from a friend that seems to point up a definite error, though AFAICT not a very consequential one: in Configurations and Amplitude, a multiplication factor of i is used for the mirrors where -1 is correct.
