Since this https://www.physicsforums.com/showthread.php?t=138637" related to Julian Barbour's theories was locked, I follow up with an interesting video documentary about his theories. http://noorderlicht.vpro.nl/dossiers/4032610/hoofdstuk/4032611/?noorderlicht.dossiers.one_man_and_his.hoofdstuk.julian_barbour&thema=wetenschap&category=noorderlicht" [Broken] (webpage is in Dutch but the documentary is in English. By the way: why was the prior topic locked? Is Julian Barbour now considered a crackpot by the resident moderator? By the way the site also has small documentaries of 't Hooft, Smolin, Kauffman and others.
