There are days when I just can't accept not being able to please all the people all the time. I teach a lot of freshman engineers, and the history course they take from me is low on their priority list. I would like to think they come away thinking more carefully about the impact of technology on society; some do. I would like to think they learn because they care and are interested, and that is probably unfair to expect. But the issues I want them to think about matter so much to me.
