According to Wikipedia, John R. Pierce “…wrote on electronics and information theory, and developed jointly the concept of Pulse code modulation (PCM) with his Bell Labs colleagues Barney Oliver and Claude Shannon. He supervised the Bell Labs team which built the first transistor, and at the request of one of them, Walter Brattain, coined the term transistor.”
“I think that I have never met a physicist who understood information theory. I wish that physicists would stop talking about reformulating information theory and would give us a general expression for the capacity of a channel with quantum effects taken into account rather than a number of special cases.”
John Pierce, John Pierce, your words cut us to the quick. They are still approximately true in 2012.
