Hi, Instead of replying too quickly to a mail, maybe I should introduce myself before. I'm a 28 years old network software engineer.
I have exchanged some mails with Bruno Marchal quite a long time ago, after an article in "Pour la Science" (french edition of "Scientific American".) I also have read his thesis : "Computability, Physics and Cognition". I'm a science-fiction reader and Greg Egan fan. I have found "everything" list from Egan's web site. I agree with Max Tegmark statement : that mathematical objets exist, "self- aware substructures" of these objets perceive their environment as real and this is why we imagine that our universe is real. I don't see why a "measure" is needed. I'm not sure such a measure could be intrinsically defined. I will try to argue about this later. I hope I don't get you bored with things you have already spoken about a thousand times. Matthieu -- http://matthieu.walraet.free.fr
