Special relativity sounds like a theory for astronauts and particle physicists, but it's already running in your phone, your wedding ring, and the cosmic-ray shrapnel currently passing through your skull. Loki explains how, and why nobody told you.

Loki considers the eternal human desire to fight fire with something that doesn't leave everything wet.
