Visualizing Polarization

Classically, light is an electromagnetic wave-- a wave of oscillating Electric and Magnetic fields instead of oscillating molecules of air or water like in sound or water waves. Electric and Magnetic fields are not something we can "see", but when they oscillate in synchrony, it results in a visual phenomenon called light! Light, a universal… Continue reading Visualizing Polarization

An informal introduction to spin and kets

Subatomic particles have an intrinsic property that is quite strange to us. Called spin, this property has the dimensions of angular momentum. It is a rather strange name because the word spin does not imply that the particle is spinning on its own axis. All we can know is that it's a type of angular… Continue reading An informal introduction to spin and kets
