Just when you thought quantum physics couldn’t get any weirder, it violates the pigeonhole principle. No, it’s not about a pigeon in a hole that is simultaneously alive and dead. The pigeonhole ...

Solve this riddle: how do you put three pigeons into two pigeonholes, with no two pigeons ending up in the same hole? If it seems impossible, don't worry; in the classic principles of nature, at least ...

The Pigeonhole Principle is a really simple concept, discovered all the way back in the 1800s. It has explained everything from the amount of hair on people’s heads to fundamental principles of ...

They say a bird in the hand is worth two in the bush, but for computer scientists, two birds in a hole are better still. That’s because those cohabiting birds are the protagonists of a deceptively ...

A new quantum phenomenon has been introduced that the authors of a new paper call the 'quantum pigeonhole principle.' The study demonstrates how to put an arbitrarily large number of particles in two ...
