@vy I never met Norbert Wiener, but I did go past his office at MIT one time. It features in the movie "Good Will Hunting", where there's an epic nerd moment in front of that office with his nameplate still there. I did meet Norbert Wiener's student Claude Shannon, founder of information theory. I met Shannon at the World Computer Chess Championship in 1989. I was part of the Caltech team, as a grad student in physics there at the time.
