This is the kind of stuff my son is into and I don't understand! I never studied any science at school - which occasionally makes me angry. I went to a v. strange school which did not seem to think science was for girls - and our general science teacher was more than a little deranged and clearly hated children (then had to leave because he had an affair with one of the older girls - whoops - so we had no teacher at all for a while). Hence I went into the Humanities. My son has a physics/philosophy blog somewhere - but it is a secret to his mum! I will definitely recommend Randall's book to him - THANKS!
