This is not just the history of the scientific investigation into why cats always land on their feet. It touches on a huge variety of topics, from the history of photography to quantum physics and shrodingers cat, as well as the history of weightlessness experiments and even cat authors. Occasionally the book feels a bit distracted, and feels like it could have been about half the length to effectively address the topic, but all of the extra information will still be interesting to anyone who enjoys reading about the history of science and scientific discoveries.
