Well, that and demonstrating that Identity Isn't in Specific Atoms because there is no such thing as specific atoms, and being a good example of weirdness being a reaction of the mind, not a property of the physics.

And, subordinate to those three, the point that Occam's Razor applies to code not RAM (so to speak). Worth mentioning since I think that's the part that went over shminux's head.

the point that Occam's Razor applies to code not RAM (so to speak).

This is true only if you are using some variant of a Kolmogorov prior. Many ways of dealing with Pascal's mugging try to use other priors. Moreover, this will be not true in general for any computable prior.

2shminux8yYou are right, it did the first time I tried to honestly estimate the complexity of QM (I wish someone else bother to do it numerically, as well). However, even when removing the necessary boundary conditions and grid storage (they take up lots of RAM), one still ends up with the code that evolves the Schroediger equation (complicated) and applies the Born postulate (trivial) for any interpretation.
1Will_Newsome8yI think the supposed Occamian benefit is overstated. E.g., the transactional interpretation has an Occamian benefit in that you don't asymmetrically reject advanced wave solutions to Maxwell's equations, and yet I don't see anyone telling me that therefore the T.I. is obviously correct. Mirror matter: predicted by fundamental-ness of supersymmetry, Occamian benefit, still highly speculative. (Don't have a PhD in physics (dropped out of high school physics), only felt justified in replying to wedrifid because AFAIK he doesn't have a PhD in physics either. Someone with domain knowledge, please correct/refine/embarrass my point.)

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.
