What if?

I’ve recently finished “What If” by Randel Munroe a collection and expansion of the posts here https://what-if.xkcd.com/ The book applies a engineering and scientific approach to absurd questions with a dose of humor mixed in. Mostly I enjoyed the explanation of the approaches in a light hearted but not mocking the question manner, it reminded me of a few of my best professors over the years I spent in school. A few of my favorites included the search algorithm he describes in Soul Mates https://what-if.xkcd.com/9/ (which now that I look isn’t in this online post), “What would be the last light left on Earth if all the humans disappeared” (also not online), and a “Mole of Moles” https://what-if.xkcd.com/4/
