When it comes to the entire cosmos, we humans are incredibly small and insignificant. But that's precisely why we need to take ourselves into account when thinking about the Universe. Find out why.

One way of making quantum mechanics independent of observers is to accept that we live in many parallel worlds.

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.
