I was taught electronics in the 70s by a elderly professor who was very familiar with tubes from his earlier life. He sometimes called parts of transistors by analogous names for tubes (or "valves", which I think would have been his name for them).
Everyone adored that man, and not just for his brilliance. He was immensely patient and kind. I think he loved teaching Physics as much as he loved Physics. He did a lot of mathematical things differently than the younger professors, and it was more intuitive, somehow. All these years later, I remember several pleasant conversations with Dr Crawford, and the impact they had on my life.
