It's the end of the world as we know it...and I feel fine.
Addendum (September 12, 2008): Brian "Superstring" Greene on the LHC. And..physics jokes!!!!
A Higgs-Boson walks into a bar. The bartender says "You know, there were some guys looking for you."
A neutron walks into a bar; he asks the bartender, 'How much for a beer?' The bartender looks at him, and says "This reminds me of a joke."
O.K., more than physics jokes. Some groaners, as well. But fun stuff.
