When I was an undergraduate at the U.S. Coast Guard Academy, I didn't have much choice when it came to electives. I was required, for example, to take four semester-long courses on nautical science, where I learned about fixes, dead reckoning, and celestial navigation. Of course, I used that knowledge when I was on boats, but since I decided to leave ocean-going navigation after two years, I have no use for that now.
I wish I could have taken a class that the news office at Duke University has told me about.They just posted an interview with a graduate student in the music department there who is teaching a class on music from the '80s. He's a classical composer by training, but he's an unapologetic fan of everything from rap to classical to heavy metal music.
