I got mine in the History of Technology and Science at midwestern University of Science and Technolgy. I taught for ten years. I now work it on a more practical level - lets call it applied S&T, and I'm working on a couple of books about what I do. One on the people, one on the technology and its evolution.
I always thought that 'in theory, there is no difference between theory and practice, but in practice there is" so I just like to work with the practical side now. I've had offers to teach, one in my field, one running a theatre tech department for the local JC. The pay was not enough - but I don't know how many more years I can climb, rig and load trucks - so I've always figured I would go back to it at some point. But for now, its like getting to play baseball for the Yankees, you do it as long as you can.
