By now I'm sure you know about the announcement from CERN that two independent groups have found compelling evidence for Higg's Boson. If you don't, you have either been in a complete media vacuum somewhere in the wilderness or just ignoring the world.
If, like me, you believe that particle physicists get stoned, make crap up, and show us unintelligible pictures and graphs to support it, I highly recommend Ian Sample's book Massive (reviewed here). It gives good historical background on this particle, the standard model, and the search for confirmation. It makes you believe in all this stuff we can never directly see.
Does this announcement change the universe in any way? Not really; it merely confirms our current understanding of the universe.
I still have to go to work. People still get sick. Kidneys still fail.
