How do the things that we use everyday work? We have some solid science behind many things, from toasters to airplanes. However, there are parts that we just "know work", without fully understanding the details of why. This book goes through a "day in the life" of a person as they encounter various technology in their daily activities. I had listened to it as I was going out to the airport on a trip. It so happened that the book uses an airport trip as a key event for many of the activities. (After all, there is a let of tech involed in travel.) It did make for an interesting listen.
