MIT Professor Marvin Minsky has died. This is very sad news - Prof. Minsky was perhaps the single most seminal pioneer of Artificial Intelligence research. I was fortunate enough to take his graduate course "Society of Mind" in the spring of 1998. It was pretty mind blowing. I'm not sure how much I understood, but it was fairly self-evident that we were in the presence of genius. If I remember correctly, much of what we discussed in the class was a series of logic exercises designed to help us reverse-engineer the brain. I loved the idea of studying the brain by conceptualizing it as a complex interconnection of simple components - using engineering to forward neuroscience?! Like I said: mind blowing. A unique, quirky, and brilliant individual.
