http://www.perimeterinstitute.ca/Events/The_Clock_and_the_Quantum/Abstracts/ [Broken] The week ending 2 October there was a conference on time and quantum theory at Perimeter. Some who gave talks were Lee Smolin Roger Penrose Neil Turok Leonard Susskind William Unruh Rafael Sorkin ... The link gives abstracts for the invited talks and for the contributed talks Smolin's talk was particularly interesting. I've watched it several times and also downloaded the slides which are available PDF as well as being shown during the presentation. The video has a slide list with 7 pages of slides. I've tended to restart on page 4, because the first part of the talk develops gradually. Starting at the beginning of page 4 of the slides list, he goes fast. Here is the link. I click on "windows presentation" which is a double screen format, there are several options: http://pirsa.org/08100049/ Smolin's talk was on the last day, the morning of 2 October. He talked a bit about his new book, that he is working on with Roberto Unger. I learned stuff about physics law from this talk, it gave me a new perspective. Among other things he made the case for a natural history of physical law.
