Reality check
Wavefunctions were adopted by quantum physicists to account for wave-like behaviour in fundamental particles. Though Schrödinger thought that the wave-function might represent reality, it's often seen as just a tool for calculating probabilities of obscure events. Maximilian Schlosshauer thinks quantum physicists should have the courage of their convictions. True, take wavefunctions seriously and our quantum universe is in conflict with what we like to think is real. But, says Schlosshauer, we must adjust our perception of reality. Somehow though, our classical world emerges from quantum theory. Philip Ball talked to the physicists finding out how. John Wheeler, a pioneer of the idea that the quantum and classical worlds can unite, died on 13 April.

How does our classical world emerge from the counterintuitive principles of quantum theory? Can we even be sure that the world doesn't 'go quantum' when no one is watching? Philip Ball talks to the theorists and experimentalists trying to find out.
