HUGS day 3: Renormalization

Quote(s) of the day (Krishna Kumar again):

on Renormalization in electroweak theory...

    "They were absolutely convinced that the theory was right. Me, I would have just said No Way!"

    "...you just take the infinities and play with them..."

on virtual photons:

    "What's a virtual photon, anyway? We just believe it! Why do we believe it? Because the theory works."

on CERN's particle accelerator:

    "Imagine crossing the border 45'000 times a second - you pay customs every time!"

After two nights of supper at Ryan's we decided to try somewhere else last night. There's Nawab, an Indian place up the road, and we invited Krishna to come with us. Luckily he goes there quite often and enjoyed educating us on the different constituents of Indian food. I also got to try some Indian beer, which beats the Bud Light and Miller Light you get here by a few orders of magnitude. Left to right around the table are: Richard, Lamiaa, Krishna, Brian, Ryan,  Scott, Mat, Jim and Mark.

After dinner we bought some beer, went back to the ResFac, and played some poker. Scott (right) has his own poker chips that he carries around with him. So you can imagine who won in the end! :D Now we had had horrible rainy weather the entire day, and we were all pretty sick and tired of being inside for so long. So somebody decided it would be a good idea to go play midnight volleyball in the rain - the ResFac has a beach volleyball court. We found a rather flat volleyball in the gym room, put on shorts and missioned off for an hour or two of what most (normal?) people would have considered insanity.

It was fun.
*grin*

And by the end of it, we were sopping wet, freezing cold (ie. cold enough to sober up) and covered in sand from head to toe. Boy, did my arms hurt this morning! And if our coordination is anything to go by, we're going to be doing physics for a long, long time!

if c[i] and d[i] are non-quarks and X is the set of quarks, further if X[i] in X, (c[i]-d[i]) <> 0, would a particle involving (c[i]-d[i])X[i] have mass=0?

yes

thanks, you must be a lepton expert.

i think the electron and muon neutrino satisfy this condition.

hey, you haven't posted in a long time....

being in america you probably didn't see the rugby on the weekend. i didn't get to see it either but at least i can brag about the win :-).
