<p>My eyes always started to glaze over whenever a math or physics professor began putting a proof on the board, whether they spoke good English or not. My gripe with math professors was that they bored students to tears with proofs, and spent no time motivating students by demonstrating how math was actually used in the real world.</p>
<p>One of the main reasons I transferred out of Ohio State (long ago) was because there were too many professors and TAs, in all subjects, who couldn’t speak English. That said, if you’re going to work in some kind of science or engineering field, you’re going to have a lot of co-workers who speak English as a second language. My first manager was from Hong Kong, and I couldn’t understand half of what he said in the job interview. It took me a few weeks to adjust to his accent.</p>
<p>Plus, I took several years of Japanese, and God help anyone who has to listen to my broken, schoolboy Japanese. So I’m more tolerant of those who aren’t native English speakers.</p>
