I did a science report in the 5th or 6th grade about a 6 volt light bulb circuit.
The teacher gave me an A+ then said, devote as much interest in your other subjects (History, Geography, English etc.) and you will become an A student.
Well that did it. It cemented my interest on the electrical/electronics world and later Electronics Engineering.

Thumbing through the pages of this PDF book brought up some good memories.
It also reminded me of the progression into advanced circuit design and theory.
After this came Boolean Algebra and after this came the horror of the Quine—McCluskey algorithm.
Totally warped my brain. Today it is counteracted by a liberal dose of AD truck information.


"Adding CFM to a truck will only help at engine speeds you don't want to use."
"I found there was nothing to gain beyond 400 CFM."
