  • The Dutch physicist Erik Verlinde's hypothesis describes gravity as an "emergent" force not fundamental.
  • The scientist thinks his ideas describe the universe better than existing models, without resorting to "dark matter".
  • While some question his previous papers, Verlinde is reworking his ideas as a full-fledged theory.

Quantum mechanics is hard to do. The great physicist Richard Feynman once remarked “It is safe to say that nobody understands quantum mechanics” and that statement was regarded as correct. The problem isn’t in the math, even an undergraduate can use Schrödinger’s equation, it is in what the math means.

The Life and Death of Schrodinger's Cat, and What It Really Means.

Schrodinger's cat is one of the most famous thought experiments of all time, but what does it mean for science, and what happens to the poor cat?

If you feel the need to put this cat in a box, you might be a physicist.
