The traditional view of quantum physics says that very tiny particles exist in many states at once until an observer measures them, which makes them choose just one state. But according to a tantalizing and incredibly controversial interpretation, nothing actually exists in many states at once — the observer just isn't sure which state it's in. Once he makes a measurement, then he knows. Conceived by quantum theorist Christopher Fuchs, this observer-centric view of quantum mechanics is called Quantum Bayesianism, or QBism for short.
