Today at 2pm the live-chat at discover.com with Prof. Lisa Randall from Harvard took place. It was a very balanced text interview in which Randall answered questions from the audience that were picked by the moderator (Amos Kenigsberg). He did a good job, it was interesting, and a lot of stuff was covered. As always, Lisa Randall was good in communicating her work.
Here are some of the more interesting questions (I wasn't able to copy and paste from the Java applet, so you'll have to endure screenshots). The person with name 'famous' is the moderator.
The first question was from someone called 'Xman':
In the answer I think Lisa Randall was referring to this paper on which I have commented in my post Why do we live in 3+1 dimensions.
As one would expect, there was a question about the LHC, and also one about the so-called string theory backlash:
She was also asked by 'qd_survivor' to comment on science blogging:
Anybody an idea what that guy was surviving? Here is my question, which I think she misunderstood:
(I don't know where these brackets come from, seems to be a software bug).
The question was whether string/loops/spin networks/other funny things out there can eventually turn out to be part of the same fundamental theory. And if mathematical consistency alone makes the fundamental theory unique. I agree on her answer, but it wasn't the answer to my question.
Besides this, I learned that the German version of her book 'Warped Passages' was just published. It seems to be one of the rare cases in which the German title 'Verborgene Universen' (hidden universes) makes sense, and imo is actually better than the English one.
A funny side remark: some time ago I piped a German research proposal through babelfish, which attempted as well to translate my reference list from German to English. The name Randall got 'translated' into Edge of the Universe. (Which is correct: the German word Rand means edge, and All is an expression for Universe.)
Update: Thanks to Georg, I found out that 'qd_survivor' has a post 'Two answers from Lisa Randall' on the blog A Quantum Diaries Survivor, where you also find a complete transcript of the chat.
