What is LHC@home?
This is kind of unique. They are testing how the new CERN particle accelerator will work once it is built. Why? I'm not sure. However, there is tons of info about it on the LHC@Home Project website. This is different from all the other LHC@Home links as they all go to the page with project info on it and the above link goes to site with info about the project in general on it. Confused yet? Oh well, you can always click a link and read, if it is not what you are looking form try the other one. Good luck!
