When I was a TA in the seventies, teaching an introductory physics lab, we had a unit on basic circuits, starting with a battery and a light bulb. I remember one kid who was very upset about it. Asking him what was the matter, he explained that he had learned all kinds of logic circuitry in high school, and had thought that he understood it, but after seeing the basics of electric circuits presented to him, he realized that he hadn’t understood it at all.
I tried to tell him that this was a good thing, not a bad thing, which I thought then and I think now, but he was just too upset. I hope he made out OK, as I would like to think he did.
He still knew Booleshit (duck’n & runn’n)
