"An Invitation to NCG" out this month I didn't want to start a new thread for this announcement, so I hope no one objects to I mentioning it here. "An Invitation to Noncommutative Geometry" http://www.worldscibooks.com/physics/6422.html" (MPI für Mathematik, Bonn) is scheduled to be out this...

The audio-visual of the Smolin-Damour debate is up. Go http://www.cite-sciences.fr/francais/ala_cite/college/v2/html/2006_2007/conferences/conference_342.htm" and click on one of blue icons.

Not related to the thread, but worth pointing out I believe. Connes and Marcolli are currently working on a monograph "Noncommutative Geometry, Quantum Fields and Motives", a preliminary version of which can be downloaded [PLAIN]"ftp://ftp.alainconnes.org/bookjune4.pdf"[/URL]. Connes' warning...

I managed to get a pdf copy of Connes' preface from the French editors (Dunod, Paris) just after the book came out. Nothing new there...

Whoops! Yes, George is right! I made the mistake of thinking in terms of the 2 identifications x\simx+2\pi R and y\simy+2\pi R, that is (x,y)\sim(x+2\pi R,y), (x,y)\sim(x,y+2\pi R), which, as I came to realize, is discussed on page 31.

No, I think it is T^2.

It is very sad to see Christine abandoning the blogosphere after one year of hard work with the blog. I think I understand how she feels to some extent, because I myself could not tolerate all the mess that has been around on blogs. I have been thinking about this whole new blogging phenomenon...

Have a go now r b-j ; )

Hi Marcus Thank you for mentioning my indeed very new blog here! I'm glad you find it good, because I was, and still am, not sure whether it will become something of interest. I am a bit busier than normal these days, but I will make every possible effort to put up what could be interesting...

This bookselling phenomenon at Amazon.com is particularly interesting for a nonfiction book which hasn't yet made it to the stores' bookshelves. I am not sure how the Amazon ranking works, and to what extent this ranking correlates with those of other bookstores (I would guess there would be a...

Self-Adjoint: I must say that author is not explicit in the book which theory he is talking about. Anyway, thanks for your effort. I might grab Polchinski (or Zwiebach?) and check. I know that the graviton was already part of the theory before supersymmetry was included in the picture. Anyway...

String theory graviton I am currently reading Prof. http://www.astro.virginia.edu/people/faculty/txt/""). A few pages ago, I read something which still confuses me. I have read, and understood, on several occasions and at several locations on the web that, even if supersymmetry does not show up...

Maverick Have a look at http://www.firstandsecond.com/" ). I believe Cambridge University Press will not start producing a low-price edition of the book unless they start getting a significant number of orders from people in India (or elsewhere in the developing countries). Btw, one...

Dimitri has got it, nice and simple.:approve: Still, one has to answer "why", which would take one into pages of algebra here. :redface:

I'm pretty sure this is not the way to think about it. J. Baez has a nice http://math.ucr.edu/home/baez/week126.html" on Week 126 as to why the classical bosonic string theory requires a 25+1-dimensional space-time. The Riemann zeta function is for something. As Baez points out, one can also...
