comment Bosonic M-theory and moonshine gravity
There is a lot of interesting numerology mentioned here but I have a hard time following the logic.

comment Why is there a deep mysterious relation between string theory and number theory, elliptic curves, $E_8$ and the Monster group?
There are lots of interesting and appropriate questions involving these topics but this broad "why" question is not going to get any kind of reasonable answer. I'd suggest you reword the question to make it a more specific question about some aspect of these relations that you are interested in.

comment $N=4$ supersymmetric yang-mills theory and S-duality
For A. do you really have trouble looking this up in the literature? The simple way to derive it yourself is via dimensional reduction of N=1 SYM in d=10. B. seems more like a demand than a question. Same for C.

I'm afraid the answer is that anonymous posters on blogs are not the most reliable source of information.

comment Treatment of boundary terms when applying the variational principle
OK, but I don't find this too helpful without some explanation of what the trickiness is or a reference to the literature.

comment Treatment of boundary terms when applying the variational principle
@Robert, yes I'm curious about your comment on G-H-Y as well. That approach seems to be what Wald does in Appendix E and he is usually quite careful about getting things right.

Thanks Robert. Let me know next time you come down to U of C.

comment Are W & Z bosons virtual or not?
Thank you Moshe.

comment Are W & Z bosons virtual or not?
@dmckee: I agree, but I think my pedantry does have some point in that it is clear that some people think of virtual particles as mysterious things which are somehow completely different from the "real" particles they observe while in fact it is all a matter of degree and using various experiments we observe particles which are off-shell to various degrees. Anyway, the horse is dead and I will stop beating it.

comment Are W & Z bosons virtual or not?
@Noldorin: Exactly how do you know my statement is wrong? Perhaps some things you think you know are not actually correct. The fact that you have never heard the term "off-shell" might be a clue. I am making a subtle point, and that is that "real" particles as they are usually defined are an idealization.
