Abstract
Wave—particle duality, still being debated 70 years later, was put into focus by a “thought experiment” proposed by Richard Feynman. If a beam of electrons strikes an obstacle with two narrow parallel slits through which they can pass, the interference between the parts of the beam passing through them is known to create an interference pattern on a detecting screen behind the slits. But there is a paradox here: Since individual quanta are absorbed by the detector, to show interference each would have to pass through both slits. But how could they do that if they were particles?
