lucid and thought provoking. reminds me of a debate about time travel years ago.....
Greene's books never fail to entertain and educate all audiences. His popular level books take readers with no scientific training into the frontier world of string theory.
Picked this book from the shelve last evening -- wanted to know a thing or two about String Theory. Interested in this concept after reading Jiang's (江) comics from Sunday Ming Pao a couple of months ago. Basically, string theory delves into the smallest part that lie in an atom -- strings are energy strands that vibrate in different frequencies. This theory lies the promise in uniting quantum mechanics and general relativity -- becoming a "Theory of Everything" -- describing matters of small and big. Those strings are infinitesimally small -- which can't be seen directly and empirically. I think one of the footnotes on String Theory is quite gripping -- claiming someone should not reject a theory on the basis that the premise/object being discussed cannot be directly observable or refutable. For example, Greene says the proof of atoms exists is shown in Brownian motion, or the proof of black holes exists is through observing gas being sucked into black holes -- but not seeing atoms or black holes themselves....Continua
I have NEVER seen a mistake in a book like in this one. Oh, it was no fault of the author, but rather the printer. Pages 17-48 are missing. Really. Not torn out, just never there to begin with. No wonder I was having trouble understanding it.
