I am a dunce when it comes to math and science. Simple concepts (gear ratios) leave me completely flummoxed. That said, this book - likely aimed towards high schoolers - was only occasionally out of my depth. I found it fascinating from beginning to end and kept sending photos to pals saying, “Wow! Look at this!!!”l
It discusses a limited number of items but in such depth that I felt sated at the end of each chapter. It starts out with clear things, everyday items with clear acrylic cases instead of opaque plastic. Telephones (the old kind), TVs (both old and new), hair dryers, shavers, all kinds of things. What I found most compelling wasn’t the innards of the products but that there’s an entire manufacturing side that caters to prisons, the idea being that you can’t hide a shank in something if the wardens can see it in plain sight.
Scales, clocks, locks, and cloth - items that we’ve had for millennia - are far more intriguing than I’d ever considered. Magnetic hourglasses, sewing machines, bank vaults, truck scales - just wow.
Highly recommended for anyone even remotely geeky (which I’m not - see math / science comment above) or who loves looking inside stuff. Really, really cool book.
