quantum locking

A short demo from Tel-Aviv University of a superconductor locked in a magnetic field, hovering and staying fixed in place. It was shown at the 2011 ASTC conference.

A short MIT Math Lab video showing millimetric droplets bouncing and walking across a vibrating fluid bath, guided by their own pilot waves. These droplets show diffraction, tunneling and quantized orbits, which were once thought to belong only to quantum systems.

A short demo of a walking droplet on a vibrating silicone oil bath passing through a double slit and producing interference, a macro-scale analogue of pilot-wave behavior.

Tested explains how Apple's Touch ID recognizes fingerprints, then tries to defeat it using fake fingers and prints, retracing methods claimed by a German computer club.
