2014/12/1
The amazing ability of sidewinder snakes to quickly climb sandy slopes was once something biologists only vaguely understood and roboticists only dreamed of replicating. By studying the snakes in a un...
Snakes and ladders: localized solutions of plane Couette flow
Snakes ladders plane Couette flow
