E≈Mc^2?

   If there's one result worth posting about from this week, it is the now famous (and in some circles infamous) exchange of neutrinos between CERN and OPERA, two European physics laboratories. Neutrinos are pretty cool as is, but what's really of interest here is what the neutrinos (muon-neutrinos, to be exact) appear to be doing on their trip from their creation at CERN to their detection at OPERA. They're arriving ever so slightly early: 60 nanoseconds early to be precise. For reference, quick calculation shows that light only travels 24 meters (just under 80 feet) in that time.
   How fast light travels is actually exactly what's at issue here; the neutrinos seem to be arriving at OPERA before light traveling along the same path would. If it is true this is the most significant find in physics for a century at least. For all practical purposes though, getting a result like this is a really good reason to check your equipment for obvious problems.
