Let me begin by saying that this is probably not in the right forum, but I couldn't find a better place for it. One of the best professors in our physics department (and the newest) just lost his wife to cancer in November. He's currently my E&M II professor, and so I spend a lot of time in his office asking questions about the homework (which is typical). He's very impersonal, and didn't even tell anybody that he lost his wife when it happened. Anyway, I can tell it's starting to wear on him. He has two kids (one 8-ish, one 5-ish). He brought in his little daughter today and she sat at the back of class, I think she was sick and couldn't go to school, and he didn't have another option. He's very serious and impersonal as I said, but I'd really like to do something for him. But as a female student that's half his age, I don't want to do anything that would be considered inappropriate (like baking him cookies or something), you know? Not really to show him that I care, but just to make things a bit easier for him.
