I really wanted to do research. That has never changed.
We learned the value of research in World War II.
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.
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.
At 13, I realized that I could fix anything electronic. It was amazing, I could just do it. I started a business repairing radios. It grew to be one of the largest in Philadelphia.
