The wave-particle duality is one of those essential pillars. Physics courses devote weeks to just introducing it – but there are still important aspects that can be covered in a short article.

Does light behave more like a particle, or like a wave? Today we know the surprising answer. Here's why it took so long to get there.

In fact it can even be in infinitely many places at the same time, exactly as a wave. Hence the notion of wave-particle duality, which is fundamental to all quantum systems.

Basically, this demonstrates that wave-particle duality is like a chameleon in the quantum mechanic culture. The creature changes form but is still the same thing.

The classic quantum mechanics problem is a particle in a 1-D box. Here is a numerical solution to that problem.

Between measurements, electrons in the quantum world are probabilistic, defined by wave functions that give the odds of finding that particle in any given position.

One of the great counterintuitive puzzles of quantum mechanics is wave-particle duality. This is the phenomenon in which objects behave both like particles and like waves. Numerous experiments have ...

In the traditional formulation of quantum mechanics, when a particle is measured -- meaning it is found to be in one particular location -- the wave function is said to collapse.
