There was a time when I was wondering about this business of going public, so I visited about a half-dozen companies in the Boston area, all of them formed by MIT faculty and all had gone public.

At MIT, I had the good fortune for seven years to teach network theory, which is basic to many disciplines, to one-third of the undergraduate student body. It was an experiment to see how high we could bring their level of understanding, and it exceeded all of my expectations.

No one ever won a chess game by betting on each move. Sometimes you have to move backward to get a step forward.

I loved music, and in my ninth year at MIT, I decided to buy a hi-fi set. I figured that all I needed to do was look at the specifications. So I bought what looked like the best one, turned it on, and turned it off in five minutes, the sound was so poor.

We did experiments with the Boston Symphony for many years where we measured the angles of incidence of sound arriving at the ears of the audience, then took the measurements back to MIT and analyzed them.

I'm forming a charitable institution for education.
