Let there be light, sound, fluids and quantum weirdness

We love physics in all its forms, from new research on mind-bending concepts like quantum weirdness and spooky action at a distance to the science of sounds and fluids to all the forces that push, pull, stick and slip. Here we tackle the macroscopic, the subatomic, the strange, the cool, the groundbreaking and the obscure.

The cloaked objects leave no wake.
