When I asked AskA{Mathematician,
Physicist}<http://www.askamathematician.com/> the
force question, here's the answer I got -- which includes a pointer to the
Feynman video mentioned earlier.In quantum field theory we talk about forces being conveyed by "force carriers". Photons for the Electromagnetic force, W+, W-, and Z bosons for the Nuclear Weak force, and Gluons for the Nuclear Strong force. There's also a theoretical particle called the "Graviton" for gravity, but there are a lot of issues with that. As for the more fundamental question of how those carriers do anything at all, or why they interact with some particles but not others (e.g., photons only interact with charged particles), there unfortunately may never be a particularly good answer for that. There's a video here <http://www.youtube.com/watch?v=MO0r930Sn_8> where Feynman addresses (a little snarkily) this very problem. *-- Russ Abbott* *_____________________________________________* *** Professor, Computer Science* * California State University, Los Angeles* * My paper on how the Fed can fix the economy: ssrn.com/abstract=1977688* * Google voice: 747-*999-5105 Google+: plus.google.com/114865618166480775623/ * vita: *sites.google.com/site/russabbott/ CS Wiki <http://cs.calstatela.edu/wiki/> and the courses I teach *_____________________________________________* On Sat, Apr 20, 2013 at 11:31 PM, Russ Abbott <russ.abb...@gmail.com> wrote: > Yes, I definitely wanted Bruce's post. > > > *-- Russ Abbott* > *_____________________________________________* > *** Professor, Computer Science* > * California State University, Los Angeles* > > * My paper on how the Fed can fix the economy: ssrn.com/abstract=1977688* > * Google voice: 747-*999-5105 > Google+: plus.google.com/114865618166480775623/ > * vita: *sites.google.com/site/russabbott/ > CS Wiki <http://cs.calstatela.edu/wiki/> and the courses I teach > *_____________________________________________* > > > On Sat, Apr 20, 2013 at 9:47 AM, Owen Densmore <o...@backspaces.net>wrote: > >> On Fri, Apr 19, 2013 at 5:11 PM, Stephen Guerin < >> stephen.gue...@redfish.com> wrote: >> >>> Aya, it turns out Bruce recently unsubscribed from FRIAM.
