I love reading John Baez's column This week's finds in mathematical physics even though I usually only understand a tiny bit of it. This week he's talking about special relativity in 3 dimensions over the integers mod 7 - fascinating stuff, and a bizarre combination of physics and pure mathematics.
This morning I've been listening to this after having enjoyed listening to the single ("Emily") on the radio all week. I kept just missing the name of the artist because they would annouce it right before playing the song instead of right afterwards, but finally figured out what it was by googling some of the lyrics. Pretty good.
