There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

It all started with beavers. When Alex Pentland was three years into his undergraduate degree at the University of Michigan, in 1973, he worked part-time as a computer programmer for NASA’s Environmental Research Institute. One of his first tasks — part of a larger environmental-monitoring project — was to develop a method for counting Canadian beavers from outer space. There was just one problem: existing satellites were crude, and beavers are small. “What beavers do is they create ponds,” he recalls of his eventual solution, “and you can count the number of beavers by the number of ponds. You’re watching the lifestyle, and you get an indirect measure.”
