I managed to stumble upon this book while looking for something fun and scientific to read. I recognized Munroe, as I read his xkcd comic all throughout high school and always loved it. In fact, it had a formative effect on me. I had read them from start to finish (as of ~2013). I was so pleased to find that this book had the same "energy" and life as his comics. I learned a lot, and I laughed all my way doing so. It made me think about some things I observe in a different way. For instance, yesterday I was on a swing. I'm 195 cm and weigh around 105 kg. I wondered what it would take for me to flip all the way around the top of the swing. I don't have any answers, but Munroe helped me realize the sort of work I would need to do to find the solution, and that I could play with all sorts of other factors as well.

Basically, it's a blast, and I couldn't stop talking about this book as I read it.
