The Multiverse: Reviving the Crazy Aunt of Quantum Theory

Physicists trying to develop a quantum theory of gravity have found that they needed to dust off the "many worlds interpretation" and apply it to their theories in order to make them work out.  

What is the idea of the multiverse?  It gets back into the issue of what entails a measurement in a quantum mechanical system.  Schrödinger himself actually disliked the idea that the Schrödinger Equation only told you the probability of finding where the electron might be at some point in space and time.

And obviously he’s got some sort of hidden superpower and some sort of Homer Simpson-type padding in his skull that’s preventing cerebral hemorrhaging.

The Physics of Invisibility

Is the idea of an invisibility cloak pure science fiction? Don't bet against the cleverness of the scientists and engineers of the future.

What Dead Cats Tell Us About Parallel Universes

Attempting to explain quantum theory, physicist Erwin Schrodinger proposed an experiment almost 80 years ago that would send PETA into a frenzy.
