"the chemistry of geometry" (Braid and Preon Update) I just finished listening to the 3 April seminar in the ILQGS series. the audio was MP3 and there were 62 carefully prepared informative slides so the format worked very well. A lot of it was a conversation between Lee and Abhay and Laurent Freidel with Sundance Bilson-Thompson speaking up now and then. Lee was the main speaker and Abhay was acting as the moderator or seminar chairman. Again the format worked remarkably well---both at the people level and the audiovisual media level. To get it you can just google "ILQGS" for international loop quantum gravity seminar and that gets you right thru to the main page, and Smolin's seminar "Update on braids and preons" is the most recent so its at the top of the menu. So you just click on PDF to get the slides and once you are ready with the slides you click on MP3 for the audio. Yidun Wan who has posted here sometimes spoke up once or twice in the seminar. Some of the work being discussed was his. Parampreet Singh contributed several questions and comments. The seminar takes place at several locations linked by wire. A "conference call" where you have the slides to refer to. Abhay at one point quoted John Archibald Wheeler saying "Elementary particle physics is the chemistry of geometry.
