On the last few chapters of "Electric Universe: The Shocking True Story of Electricity" by David Bodanis (http://www.davidbodanis.com/pages/Electric_universe_pg.html). I can't say it grabbed me like some other books, but it was worth the read.
I learned that Thomas Edison was a bit of a prick.
I never thought about the early ideas of electrons running through wires "like water through a hose" metaphor, if accurate, would end up with piles of electrons sitting on one end of a telephone line, assuming one speaker is chattier than another.
Heard again about the tragic life of Alan Turing, and the poison apple.
Never really thought of what the term "semi-conductor" really meant/\.
