An Imaginary Tale: The Story of the Square Root of Minus One, by Paul J. Nahin

3.0

I held on for the first few chapters but this ended up being quite a difficult read and I had to skim over most of the math. Despite that, it was a very interesting read and I learned a lot about sqrt(-1). I hope to return in a month or so for another go, with a pen and paper close at hand!
