Towards a Theory of Everything Boston.com / News / World / Three Americans share Nobel physics prize for study of forces inside atomic nucleus. According to the official announcement "Thanks to their discovery, David Gross, David Politzer and Frank Wilczek have brought physics one step closer to fulfilling a grand dream, to formulate a unified theory comprising gravity as well – a theory for everything." The claim that Quantum Chronodynamics accounts for everything seems an odd sort of claim until you understand that "everything" means, all the pieces to the puzzle underconsideration. The pieces in this case are electromagnetic force, the strong force, the weak force and gravity. Once these are all put together, there aren't any other forces hanging around waiting to be discovered.

Anything you can talk about that isn't one of these four forces, which includes just about everything an ordinary person might discuss on an ordinar day, don't fail to be explained as they just don't show up at all. They're part of the picture that will ultimately be revealed by the completed puzzle perhaps, but this isn't about figuring out the picture, its about getting all the peices to fit.  ¶ #
