Wonderful Book in the Forest Mims Tradition
Reviewed in the United States on October 21, 2013
I'm an EE and a lot of us older folks learned circuits and electronics reading and studying the awesome hand-drawn diagrams of Forest Mims. Here's an example of one of his best: The Forrest Mims Circuit Scrapbook, Vol 1. Search Forest Mims for many of his others.
I've tested nearly all of the circuits in this fine little book, and Sarah has done an outstanding job of double checking functionality, so you don't burn your workshop down. To be brutally honest, even some of Forest's had little resistor or power supply errors, so not many of these are as carefully vetted at this one. Back in the day these used to be copied from component manufacturer spec sheets, which sometimes were rushed to press, and some errors have continued for decades.
Allen is a wonderful teacher, and I've read and reviewed most all her titles, and require them for our online tutorials. Her pedagogy is to teach, give a problem you can try, then show you the solution. She is frankly a perfectionist and loves her readers, and when we pointed out a graphic on another review that was a little difficult to read on Kindle, she corrected it instantly, on ALL her ebooks!
If you're getting into Ohms law, circuit basics, etc. this is a wonderful place to start, whether for class or as a hobbyist. Sarah's value add is to give little "intuitive" examples with a wonderful array of diagrams so you "get" a concept in ways other than just the math. Her explanation of little diagrams showing position vs. momentum, for example, casually shows how this underlies all differential and integral calculus, and although fine for a High School audience, the point illustrates aspects of QED and Heisenberg uncertainty (the inability to resolve position and momentum simultaneously, or any conjugate Fourier for that matter-- time/frequency, sound, MRI images, etc.) in a way much more intuitive than taught in physics classes.
Highly recommended, for the price, I'm getting my grandkids her whole series for school! You can find them all on her author's page.
