These pages explain quantum entanglement by way of pictures, analogies, but without math.

To understand quantum entanglement, several ideas and words must be explained, especially the idea of a photon. The photon is a key concept in physics, and so critical to entanglement that its behaviours must be fully understood. But before delving into the details of photons, let's take a look at the world of the tiny, beginning with waves and atoms.
