Quantum PhysicsUltrasmall engines bend second law of thermodynamics
Car engines and batteries run because of the second law of thermodynamics, which appears to work, with just a little bending, for ultrasmall engines in the quantum realm as well.

Particle PhysicsEntanglement is spooky, but not action at a distance
Recent experiments on quantum entanglement confirm that it’s spooky, but it was not, as Einstein implied, action at a distance.
