I wonder if anyone has some fun or interesting stories about their high school or university physics teachers. In my case there are several, and some of these teachers had tremendous reputations. These were actual professors of mine, so I know this is not apocryphal. Of course I will never reveal their names. (1) On a physics test, there was a multiple choice question about the meaning of E = mc2. The correct answer according to the teacher was "energy and matter are the same thing." I questioned this at the time, and recently I heard the audio where Einstein said that it means "mass and energy are both but different manifestations of the same thing", which is not quite the same in my opinion. What do you think? Anyway I answered the question "correctly" while wondering if the teacher was playing some kind of joke by asking it in the first place. Sorry but I don't remember the other answers, just that they were obviously wrong. (2) A teacher who was an expert in cosmology was asked in class how the universe came into being from nothing as he stated. His reply was "nothingness is unstable." Again, an apparent joke. Or was it? How would you answer this question? (3) A teacher was asked which was the best choice of a foreign language to study: French, German, or Russian. He said he had studied both French and German because they were required for his PhD, but they were not useful. Also he said "Russian is impossible." It was funny because this guy was at ease with quantum mechanics and wrote a well-known physics textbook, yet he said Russian was impossible. I wonder how many Russian physics teachers would say that about English. (4) I was talking to a guy who was said to be a very careful experimentalist. We were discussing the solution to some mathematical problems and he said not to worry too much about getting exact solutions because "physics is sloppy." I was surprised by his answer because he seemed so enthusiastic when he said it. At the time he was showing me some very delicate equipment he was assembling. Here is the Einstein audio. If only we had videos of Einstein's lectures!
