Richard P. Feynman (1918–1988). This is a unique Feynman biography that tells of all the technical mischief he got into in his lifetime. Much of it I paralleled (we both had a crystal radio as children), but some of the stuff he did is off the chart.
It is a tad spooky reading about his early experiment, Smith radios, as I grew up a generation later and still played with a lot of the same stuff. I learned how to use half of a defective valve (vacuum tube) for projects. Turning a CB radio antenna sideways gave an extra channel. Chemical sets, Kenner Hydraulic sets, etc.
In this biography, Feynman gets away with finding an easier way to do trig. In the book “A Wrinkle in Time” by Madeleine L'Engle, Catherine is admonished for getting the right answer the wrong way. I found in real-life engineering that the number used for conversion of cubes and spheres is quarter pi (0.785398163), and it is easy to remember by starting with six and counting two-up “7 and 8,” then two down “5 and 4” to get an approximate and calculate the answer in your head.

There are no pictures in the book; the descriptions are such that you can draw pictures in your mind as you are reading.
