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.

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.

All military and most commercial aircraft use our designs that process power from jet engines.

One hundred percent of our earnings are reinvested in the company, and a great deal of that goes to research.

I'm forming a charitable institution for education.

I really wanted to do research. That has never changed.
