The Power Guide: An International Catalog of Small-Scale Energy Equipment Book

In my opinion this book stands on a very different ground than the other ones. First of all it's shorter and does not comprise a full length course on the subject, it's merely an introduction. But besides that structural difference my opinion about it differs quite substantially from the other two.

For the other books in the series my TL;DR opinion was very interesting for who already knows physics, possibly confusing for a beginner. On the other hand I think the first chapters of this book offer the best introduction to quantum mechanics I have ever read. I think the usual way to teach the subject is many orders of magnitude worse than this. He focuses on the essential measurable quantities of quantum mechanics, amplitudes, and gives them a clear and coherent interpretation and rules of calculation. After his introduction I think the mathematics of Hilbert spaces would be really intuitive and natural, way more than if you started with wavefunctions as is usual.

The only drawback is really the context of these lectures. This isn't a full course so he couldn't show all the structure and went straight into applications as soon as he could. Going back to the "interesting for who already knows about this, overly complicated for someone who doesn't know anything".

I think lectures of quantum mechanics should really come to this book for the first few lectures. The very first chapter explaining the double-slit experiment (of which there is a recording online) and the chapter about spin one with the Ster-Gerlach experiment are absolute genius.
