<p>A bit off topic, but I went to school with a friend whose father was a math prof at The University of Michigan 30 years ago. He complained one day of an instance where an engineering student asked an interesting question on theory. He was thrilled with the question and was excited to respond when other engineering students in the class complained that this was not pertinent to the class and considered it a waste of their time. He was very disappointed with most of the engineering students he taught. Unfortunately, some people only want to know what they need to know.</p>
