I forgot to include in my last post that I had magnificent mentors. One used to work at Bell Labs. One was from Lockheed Aerospace. I even had very quality mentoring from one of “Grace’s Girls”. The best tutor during my undergraduate studies was an IBM CE; and, he was trained at a number of IBM schools.
I am duly imporessed.
Grace herself once handed my father a length of wire (about 10 inches long) saying that it represented a billionth of a second of electronic transmission.
