True, I've forgotten. But I'm sure there are others here who have not. I may not be able to actually "do the math" any more, but I think I can follow the big picture, if you'll give me a chance.

Really. I work with people a lot smarter than me every day. Most of them are practicing scientists. My entire professional life consists of being in over my head and dog-paddling to shore and while I may have forgotten QM, I think the fact that I actually understood - at least the introductory stuff - at one time shows that I'm at least capable of following it.

Give me a chance. Please provide one sentence from the paper and explain exactly how it is false.
