The double-slit experiment is the most important experiment in the history of physics.

Richard Feynman called it a phenomenon which is impossible to explain in any classical way and which has in it the heart of quantum mechanics.

When particles are fired at a barrier with two slits without detection at the slits, they produce an interference pattern on the detection screen - a pattern characteristic of waves, not particles.

The particles appear to pass through both slits simultaneously, as waves, and interfere with themselves.
