Since quantum mechanics predicts such strange things about the world, should we replace it by a better theory, or perhaps extend it?
If observers can influence the outcomes of measurements, then do these observes need to be conscious? Does consciousness play a special role in physics at all?
A brief introduction to the strange theory of quantum mechanics and how it appears to afford a special role to observers.
Inspired by The man who knew infinity, here's a review of G. H. Hardy's unrivalled masterpiece.
So easy to describe, yet so hard to prove.
Clever geometry produces materials that shrink when heated.
Computer scientists have made a breakthrough in the theory of cake cutting.
With all the trouble caused by quantum mechanics and people's attempt to construct a theory of everything, we might be better off defining an event without reference to time and space. It's easier than you might think!
