Victor at least spell Brian's last name right in your subject line.
This just in from Doctor Faustus: On Feb 28, 2004, at 9:18 PM, Faustus wrote: Dear Jack : I will be mailing you the reprints of : "On the variable fine structure constant, strings and maximal-acceleration phase space relativity" ..... some reprints about Anti de Sitter space, and Clifford algebras that may be useful .... I've mentioned to ... once how fed-up I am of reading the same techno-babble-****, over and over again, in the hep-th/archives. It is true that string theory has very nice mathematics involved. But there are no fundamental new physical ideas for a long time, let alone calculations that can be verified and tested in the lab. Even worse : they do NOT even know WHAT string theory IS !!!! .... Even worse they admit it and no one calls them on it. Talk about double standards. Physics Today is like High School Cliques in the soft core porno version of American Graffiti on the Shopping Nitwork Channel for Elegant Tailors. ;-) Strings, Supersymmetry, Supergravity...are more than 30 years old and after rivers of ink, not a single experiment has verified it. Take Connes' Noncommutative Geometry. It has been more than 20 years. Many fancy books have appeared. After you go through the tedious and boring chapters about cyclic homology etc....and finish the book, you have a very empty feeling that it all has been useless because you cannot calculate anything that can be tested in the laboratory. This is all a hype. People think that by doing very complicated academic mathematical exercises they are going to discover new physics. This is not the way to do it. Now, I can understand Feynman's feelings about string theory. Hoist them, or rather, hang them by their own G-strings! ;-) On Feb 27, 2004, at 11:18 PM, Victor Martinez wrote: SAUL-PAUL: 1) GREAT! I can tell you're making fine use of Dr Greene's GREAT book FABRIC OF THE COSMOS.

Working together, we can bring the Doc up to speed! 2) Dr Sarfatti had queried you earlier about Greene's writings on mirror symmetry, so here are some very useful sites for everyone to utilize.

Brian Greene and Ronen Plesser discovered a duality that became known as mirror symmetry. In the book *Mirror Symmetry and Algebraic Geometry* by David A. Cox and Sheldon Katz (American Mathematical Society, 1999) we read: "Early evidence for mirror symmetry of Calabi-Yau threefolds was given by lists of Calabi-Yau hypersurfaces in weighted projective spaces (or their quotients by finite groups). The Hodge numbers of these hypersurfaces, mirror symmetry was demonstrated in [GPl] by first showing mirror symmetry for certian Landau-Ginzburg theories ... and then relating these theories to the sigma models of the [Calabi-Yau] hypersurfaces." [GPl] is the reference: B. Greene and M.R. Plesser, Duality in Calabi-Yau moduli space, Nucl. Phys. B 338 (1990), 15-37. There are two other Greene references in the bibliography: B.R. Green, C. Vafa & N.P. Warner, Calabi-Yau manifold and renormalization group flows, Nucl. Phys. B 324 (1989), 371-390. B.R. Green, M.R. Plesser & S.S. Roan, New constructions of mirror manifolds: Probing moduli space far from Fermat points, in *Essays on mirror manifolds* (S.-T. Yau, ed.), Internat. Press, Hong Kong, 1992, pp. 347-389. Mirror Symmetry has become a hot topic in string theory. A recent tutorial book on the this topic is" *Mirror Symmetry* by Kentaro Hori, Sheldon Katz, Albrecht Klemm, Rahul Pandharipande, Richard Thomas Cumrun VAfa, Ravi Vakil, and Eric Zaslow, published by the American Mathematical Society and the Clay Mathematics Institute (2003). This book cites in addition to the Greene Plesser paper of 1990 two more Greene coauthored papers: B. Greene, D. Morrison, & A. Strominger, Black hole condensation and the unification of string Vacua, Nucl. Phys. B451 (1995) 109, hep-th/9504145. B. Greene & H. Ooguri, Geometry & quantum field theory: A brief introduction, in *Mirror Symmetry II (B. Greene & S.-T. Yau, eds.), AMS/IP Stud. Adv. Math. 1, AMS, Providence, RI, 1997, 3-27. Although I have only recently started reading the two Mirror Symmetry books (of 1999 & 2003), I am intrigued by the fact that the A-D-E classifications (via the A-D-E Coxeter-Dynkin graphs) plays a big role in this topic. I already knew that the 2-d superconformal field theories are A-D-E classified. But it was news to me that the these theories correspond to certain Landau-Ginzburg theories, and the correspondence is via the A-D-E Thom-Arnold catastrophe germs. On page 337 of the *Mirror Symmetry* (2003) book we read: "It turns out that (2,2) superconformal theoris with c 3, or equivalently D 1, can be classified and all correspond to Landau-Ginzburg theories with quasi-homogeneous superpotential. Moreover they are in 1-1 correspondence with ADE singularities of C^2/Gamma where Gamma is a discrete subgroup of SU(2)." So the McKay correspondence of the subgroups of SU(2) with the ADE Kac-Moody Lie algebras is also entailed in the subject of Mirror Symmetry. I have long conjectured that the the A-D-E classifications will provide the underlying mathematical structure for string theory and its later development into M-theory, Mirror Symmetry (which is a kind of T-duality) and so on. There are 20 some mathematical objects already A-D-E classified (including now a potent kind of Landau-Ginzburg superpotential). I call the study of all the A-D-E classifications and their applications to mathematics and physics by the name ADEX-theory. I will attach a paper I wrote for ISSO and ISEP in 2000. I see that it needs some updating after I have absorbed this (new to me) Mirror Symmetry stuff. Apparently Brian Greene's peers consider him to be an important early developer of the Mirror Symmetry. Perhaps his next book will be a popular description of these ideas. Nuff said ;-) Saul-Paul Subject: Peer Review of Brian Greene's books Date: Thu, Feb 26, 2004, 9:21 PM [Jack Sarfatti wrote] I received this from someone active in the field. I did not write it. I am merely passing it on. [Anonymous physicist wrote] "About Brian Greene's new book.... it is nothing but another sales pitch for the string mafia. All the experiments looking for signals of Supersymmetry have failed. This was a big blow to many. This is all a hype to get more money. I have worked on Supersymmetry and Supergravity for a while, and published papers in reputable journals on that topic. It is a nice academic exercise. The person who wrote : BRIAN GREENE is widely regarded for a number of groundbreaking discoveries in superstring theory. This is bull**** and simply not true !!! . I have followed the string theory developments for the past 20 years and I can tell you that Brian Greene has not done what it says above. It is propaganda. You just have to read Susskind's article about the history of strings to figure out that Brian Greene has not done much but to write popular books and act as the string theory sales man. ... ... It is very simple : Just look at Brian' Greene publications in the past 20 years. He wrote a nice review on Calabi-Yau and String Geometry which I read, however this work was mainly done by others Aspinwall, Morrison, Candelas, Vafa, Yau, Strominger, Witten, .... What a bunch of lies and bull**** ! This is not to say that if Brian Greene had devoted himself to research, instead of writing popular books, he would not have accomplished great things. Money, money is very tempting." |
