The Upward-Driven Disk, a Steadily Forced Chaotic Pendulum
Leo Maas
An "upward-driven disk" is a novel mechanical device built from LEGO parts. A circular disk is suspended from the point where it is sandwiched between two wheels, making it free to…

Relating interfacial Rossby wave interaction in shear flows with Feynman's two-state coupled quantum system model for the Josephson junction
Eyal Heifetz, Nimrod Bratspiess, Anirban Guha +1
Here we show how Feynman's simplified model for the Josephson junction, as a macroscopic two-state coupled quantum system, has a one-to-one correspondence with the stable dynamics…
