ok guys a new LHC member only 2 days old... i was watching The elegant universe and heard brian greene saying something about the only experiment that could detect strings for string thoery would be like a graviton or SOMETHING LIKE THAT.. idk. but i saw that you could add particles with "a" and remove them with "r" and clear them with "c" ... well my question is when i add alot the numbers start chruching slower... then when i clear it i think they go somewhat faster .. is this true.. and what exactly are is LHC doing... like the number of particles you have ... does your computer crunch that amount of particles.. please help me =)

The LHC screen saver doesn't relate to the calculations SixTrack is doing. It represents a number of particles moving under the influence of mutual attraction. Yes it's pretty, but youcan't really tell what LHC is about by looking at it. If you add more particles then the screensaver calculations take more time, and less time is available for SixTrack. The autopilot feature tries to balance this by reverting to a standard configuration for the screen saver when nobody is playing with it.

The basic model that sixtrack is running is simulating the movement of particles in the Large Hadron Collider that is under construction. Each simulation looks at various energies, start conditions, etc. and then runs the simulation to see if, and when, the particles run into the walls. The whole point of course is to see what happens ...

The screen saver, as stated, does not work like the one in SETI@Home which actually shows the data being processed. Other projects where the screen saver does show what is going on are CPDN and Einstein@Home. Predictor@Home at this time only shows "slides" of protiens ...

This is admiditly a weak area in the Wiki, we don't talk enough about what the projects are really doing (well, Chris C. has done a supurb job with our CPDN section ... so that is one place where we are better ... also we did capture the SETI@Home material as Dr. Anderson did give me permission to copy his site's material)

Note to LHC@Home staffers ... if you would like to improve the Wiki's LHC@Home material you are welcome (so much so) to become a contributer/editor of the Wiki ... Send an e-mail to p.d.buck@comcast.net for me to add you to the editor's list.
