### Discover's online chat with Lisa Randall: tomorrow

The title should say "today" but let's not break the links.

Incidentally, Lisa Randall's book was just released in Germany - see amazon.de - which might be interesting for many German theoretical physics fans among the readers. Sure, her "Hidden Universes" are Nummer Eins among the Naturwissenschaften & Technik books, in front of Al Gore's "Eine unbequeme Wahrheit", and in top 20 of all books. See also a Swiss interview with her, a German review, and most importantly an article in Stern (English). You should also try to use Altavista's Babelfish to translate "Randall Sundrum" from German to English: the translation is "Edge Universe Sundrum". ;-)

Discover's online chat with Lisa Randall takes place today, on Thursday, at 2:00 p.m. EST:

Update: Lisa has answered various questions such as why the number of dimensions is three (and not seven - which is also possible in their brane relaxation argument), whether she can imagine extra dimensions, and why the exponential warping can't solve the cosmological constant problem.

The people who are close to London may want to attend

that is a serious celebration of the 11th anniversary of 11-dimensional M-theory. On 11/11 at 11:11:11, it will be just the beginning of a break after a talk about sevenbranes in type IIB supergravity. ;-)
