Peter is part of a sub-team working on the Compact Muon Solenoid. (From the linked site):
- CMS is designed to see a wide range of particles and phenomena produced in high-energy collisions in the LHC. Like a cylindrical onion, different layers of detector stop and measure the different particles, and use this key data to build up a picture of events at the heart of the collision.

Big, big stuff.
The LHC was just fired up for the first time this week (details). To mark this occasion, the Physics Department held a forum this past Tuesday evening. Peter and another Cornell scientist, Yuval Grossman, spoke. There were refreshments, related instruments on display and some small demonstrations. There was a good turnout - including some children - and everyone there seemed engaged and enthusiastic.
It is an exciting project, and the scale - of the LHC itself, the international involvement, the cost, the amount of data that will be produced and analyzed, etc. - is mind-boggling. Peter and Yuval broke down the "science" during their presentations, with easy-to-follow everyday examples as analogies for more complicated concepts , as well as some jokes and, of course, Dilbert cartoons.photographer - see some of his lovely shots of the Ithaca area, too).
Peter jokingly instructed his students to come down front and dance. That sent a few of them scurrying to the exits with their backpacks.
Unfortunately, there was a helium leak and a restart of the system is expected in Spring 2009. Huge operation - so many systems to keep functioning at once. Press release.
