To Joanne and other members of the SSI organizing committee, a sincere request I have, which is to upload real videos of the talks on the web. From the slides itself I can see that all of them were great talks and I am curious to watch them Thanks Sean for the update.

I agree with Stan. They are a great resource. Thanks Shantanu Sean and others ,

Nice Hawaiian shirt, Scott. And no, I haven't changed my research specialty. It's California, they don't sweat the details. I’m going to have to give Hughes a hard time. Nice Hawaiian shirt, Scott.

I thought I just heard Scott say... ;) (Heckling from 6 rows behind you.) Hey Sean, which books have a good proof of Birkhoff’s theorem?

Did you recently changed your area of research? :-) Sean,

I do recall from Kip Thorpe's book him mentioning that, in principle, one should be able to detect gravitational waves from the big bang since they don't interact strongly with other particles and that was what particularly intrigued me, but I don't recall him saying what one might discover, whether one might be able to say something about inflation, say. Anyways, don't want to waste your time. The blog's terrific; the string theory post and thread were really interesting. Sean - Thanks. I do recall from Kip Thorpe’s book him mentioning that,

We should go more deeply into later. TM, there are a lot of things, starting with making sure that gravitational waves actually exist and do what we think they do. (Nobody doubts it, but in science it's always nice to check.) Then there is honest astrophysics -- learning about binary stars and supernovae and black holes and gamma-ray bursts and whatnot. Especially the "whatnot" -- as a rule, any time we look at the sky in some different waveband, we discover new phenomena. Finally, there's more speculative things we can check about black holes or the early universe. But the real fun in doing an experiment is that we don't know ahead of time what we will see.

That would certainly make a good physics post. Listening to Sarah Church’s talk on the CMB, it occurs to me that none of you have a post explaining what Cosmic Variance is.
