Here's a chance to put your computer's idle CPU hours to use! The SETI@Home project takes recordings of data collected by listening at specific radio frequencies using radio telescopes (most notably the large radio telescope at Arecibo, Puerto Rico) and studying the data for patterns which might be artificial in origin.
Participants in the project download work packets, which are analyzed by the client software when you aren't using your computer. The analysis is uploaded to SETI@Home, which then gives you another packet, and so on.
If you join the Lunch With George! team, we can work together and be recognized for our efforts as a group, as well as individually.
