*********************************
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

Invisibility cloaking illustrating how cloaking works. On the left, electromagnetic waves, which could be light, scatter upon hitting the cylinder in the middle. On the right, the cylinder is cloaked; the waves do not scatter, and to a beholder standing on the field, it would appear invisible.
