I've used this comic from "Toothpaste for Dinner" before, but I still like it.
I stumbled across this guy, today, he has a site called "FreeLance Teacher" and he films himself in front of a chalk board explaining chemistry, physics, and mass spectrometry. You can "pay what you like" for his videos, but they are pretty decent. I don't know enough about MS physics to say whether what he's saying is true, but he seems pretty confident about it. Interested in what's going on behind that sweet plastic casing? Check these out!
