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

Abstract:
In this talk, I describe 3 counterintuitive behaviors in simple physical systems. First, I describe experiments showing that small particles climb up a waterful to contaminate a clean reservoir upstream. Second, I describe climbing of shear thickening fluids up a vibrating rod. And third, I describe separation on fine grains from large boulders on asteroids.
All of these behaviors are surprising and counterintuitive, and all follow from mathematical and physical principles that have been known for decades, but have only recently been rediscovered.
