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

Henry Segerman is a mathematician whose research is in the areas of 3-dimensional topology and hyperbolic geometry. He is also the author of the upcoming book Visualizing with 3-D Printing. According to his website (www.segerman.org), "The twist with this book is that whenever it makes sense, figures in the book will be photos of 3D prints that readers can download and print for themselves, buy online, or rotate around on screen."
