———————— * This joke is for everyone who’s ever loved (or hated) the quantization of total angular momentum, J. The z-component of total angular momentum is denoted by Jz. For a given j (the quantum number that characterizes the magnitude of total angular momentum as J=ℏ√j(j+1) ), Jz can have 2j+1 different values. * In case you don’t really follow pop-culture, the joke refers

————- [1] The stamp-collecting snub is among Rutherford’s quotes [2] Rutherford really did die of complications after a delayed umbilical hernia surgery.

The semester started last week. I am again teaching a junior/senior elective for majors and it looks like it might be a rough semester. The course I am teaching follows a basic, required course in the major. I find the students are poorly prepared, more poorly than the class I had last semester. The students are

This is a cute movie on the famous double-slit experiment, featuring a caped and bespectacled superhero Dr Quantum. I show it in class to my undergrads as they first get exposed to quantum mechanics. Enjoy!

While it would be totally cool if we were to reveal that Erwin Schroedinger, one of the fathers of quantum mechanics, had been a proto-blogger of some kind, I am afraid no such luck today. Schroedinger’s cat is a well-known thought experiment that emphasizes how critical the concept of measurement is for “knowing” things in
