Long ago, I worked at an R&D center at the University of Texas at Austin. It was a fun job. One the the perquisites of working at a university is that you hear about and can attend all sorts of lectures. A hero of mine, Oliver Sacks, the neurologist, writer, and lover of ferns, came by one day and talked about his research. Another time Richard Avedon discussed his photography. And once, a professor of Human-Computer Interaction lectured to us about what he had learned from the research and design of airplane cockpit hardware and software.
