QUANTUM MECHANICS

Let’ s face it, quantum mechanics is weird. Niels Bohr, the Danish physicist who helped to invent the field, said, "Anyone who can contemplate quantum mechanics without getting dizzy hasn’ t properly understood it". To appreciate the weirdness of quantum mechanics, we need accept only a single strange fact called wave-particle duality.

Wave-particle duality means that things we think of as solid particles, such as basketballs and atoms, behave, under some circumstances, like waves and that things we normally describe as waves, such as sound and light, occasionally behave like particles.

The first strange implication of wave-particle duality is that small systems such as atoms can exist only in discrete energy states. So when an atom moves from one energy state to another, it absorbs and emits energy in exact amounts, or packets, called photons, which might be considered the particles that make up light waves.

A second consequence is that quantum-mechanical waves, like water waves, can be superposed, or added togheter. Taken individually, these waves offer a rough description of a given particle’ s position. When two or more such waves are combined, though, the particle’ s position becomes unclear. In some weird quantum sense, then, an electron can sometimes be both here and there at the same time. Such an electron’ s location will remain unknown until some interaction (such as a photon bouncing off the electron) reveals it to be either here or there but not both.
