In my teaching, I tend to write a lot of Greek letters on the board. Students from physics and mathematics are comfortable with this and can make out my squiggles easily. To make things easier for students coming from biology, I write out the names of the symbols, the first few times I use them. This helps a lot, because they are not just unfamiliar with the symbols, but also the words I use when I talk about them. Another thing I do is to pronounce symbols in both the Greek and the American ways. That helps them in other classes, because where I teach, the professors are about evenly divided in their pronunciation. PS. my squiggles are basically identical to those in the article under discussion here.
