Dr Quantum - Double Slit Experiment

This is Video is amazing! Looks like this would be an indirect answer to "If a tree falls in a forest and no one is around to hear it, does it make a sound?"!

In physics, wave-particle duality holds that light and matter can exhibit properties of both waves and of particles. It is a central concept of quantum physics. Through the work of Albert Einstein, Louis de Broglie and many others, it is now established that small objects, such as atoms, have both wave and particle nature, and that quantum mechanics provides the over-arching theory resolving this apparent paradox.
