	Lee Smolin is a well-known physicist and the author
	of The Trouble with Physics: The Rise of String
	Theory, the Fall of a Science, and What Comes Next.
	The book strongly contrasts with recent efforts by
	Brian Greene (see 1, 2 and 3) and other advocates
	of string theory, as Smolin thinks that (a) string
	theory is, if not a dead end, a far less promising
	approach than its friends think, and (b) the
	community of string theorists wield an almost
	punitive influence over those pursuing alternative
	approaches to a theory of quantum gravity....
