<p>I’ll share a story. S was taking a chemistry course at an top Ivy and began wondering about some theoretical aspect of what was being presented and asked the grad assistant about it. The grad assistant said he didn’t know, so S said perhaps they (the section) could derive it. The other students asked why he cared, but S tried any how, finally he said he needed some advice from either a chemistry or physics prof, and asked the grad student if the prof giving the lectures was available. He was told the prof would not want to be bothered. He went looking for one (they were in the science building) and found none. Finally S, took out his notebook computer opened it and emailed his quite famous Chicago physics professor he had the previous term with his question. Before the end of the section he received an email with a detailed answer and a verbal pat on the back for thinking of the issue in the context of his course. the other students were shocked, they had never seen anything like that before.</p>
