I was talking to my friends about Euler’s identity and I was reminded of this one: The most beautiful equation in math, explained visually [Euler’s Formula].
In that context one of my friends brought Tau Day to my attention.
This is good: Calculus Visualized – by Dennis F Davis.

In this video I take a look at Electrical Engineering 101: Everything You Should Have Learned in School…but Probably Didn’t 3rd Edition written by Darren Ashby and published in 2011.
In the book the author mentioned that they used to write for chipcenter.com which appears to have since been taken over by EE Times. ChatGPT provided more information.
The author also mentioned Mathcad. I’m planning to check that out over here: https://www.mathcad.com/
And some terms which came up (ChatGPT explains further):

Note: this video is nearly five hours long! If you’re interested but don’t have 5 spare hours (and who does??) you might like to listen at 2x speed or more. The standard YouTube interface only supports playback up to 2x speed but I have some notes about YouTube hacks you can use to set the playback at 3x speed… or more!
In this video I teardown “Radio Engineering” (3rd edition) by Frederick Terman published 1947.
Frederick Terman was a Doctor of Science which is what the Sc.D. after his name stands for. It’s like a Ph.D. He is remembered as a father of Silicon Valley.
In the book there is much talk of diodes, but of course that is in reference to the old thermionic diodes which were vacuum tubes. These days diodes are semiconductors made from something like silicon or germanium.
The book talks a lot about power amplifier classes. Today the same classes are still used, it’s just that anything other than class AB and class D are very uncommon.

This video is part of the Old Book Teardown feature of my video blog.
In this video I tear down Engineering Electronics with Industrial Applications and Control by John D. Ryder. This book was published in the USA in 1957. The book comprises 666 pages and is chock full of schematics with old vacuum tubes and photos from old Cathode Ray Oscilloscopes (CROs).
