Your favorite book (genre: STEM )?

[Jim Horn]

"The Feynman Lectures on Physics" - when I run across a mind-boggling concept such as the symmetries of physics proving the conservation of energy, momentum and angular momentum, I find that Feynman already explained it there 50+ years ago. And clearly. It deserves the praise it gets.

"Godel, Escher, Bach: An Eternal Golden Braid" - warped my brain back in 1979 and has been referred to ever since.

"The Scientific American Book of Projects for the Amateur Scientist" - C.L. Stong's early columns from that once august magazine that led me to engineering as a child.

Martin Gardners "Mathematical Diversions" books (many) - again, from Scientific American, which taught me the love of Math and what I refer to as 'orthogonal thinking' to solve problems which has served me well. Lots of fun, too!

Too many others to include but the above have been pivotal for me. Enjoy!
