I like the song, though the mention of a “He” is somewhat puzzling, if the song is trying to teach students about a scientific concept. In any case, Professor Knox is a talented musician. I wish one of my professors would do something like this… I seem to only catch such moments on YouTube! (I am a UCD student, who loves Cosmic Variance.)

To David Degner: This analogy is well-known, but what you have only works for *classical* gravitation. If you do relativistic gravitation, there is even more that can be done. In particular, there is an analog to the magnetic field (with a VxB term in the ‘Lorenz force law’). The main difference is that ‘mass’ has only one sign, instead of the ‘charge’ which can be either sign (positive or negative). This comes about because gravity is a tensor interaction (spin 2) rather than a vector interaction (spin 1).

Please adopt a strict one post per day policy on this blog. Seriously, there are like seven of you. Give each person a day of the week if you have to. Tired of coming here and being disappointed.

The fact that it’s set to the tune of one of my all-time favorite songs certainly clenches this one for me. Hooray!
