2012-02-20, Dear Delia, you're right! Only AV gave a talk at the ( my ) Harvard smainers and I may have seen your MIT talk, after all: that would be 1 out of only 15 talks at MIT I've ever seen. And maybe not. I should remember but something has evaporated here 500+ smainers requires nonzero memory.Some memories concerning my deeper impressions may be returning. It seems to me that I thought that AV was behaving as a new Russian , a kind of guy who also has to be surrounded by hot women, not just physicists. That was before I noticed you were a real deal, of course. You're also correct here your work is actually discussing both limits. However, there are additional scales playing some role here the KK radius, size of the instanton, string scale, Planck scale. It's supposed that the fundamental scales (the latter two) are shorter.My grandfather was a painter but unlike you, I can't do any of these things well. Wishing you the best, LM
