Furry Logic is a fascinating look at the behavior of animals through two scientific lenses - biology and physics. Each chapter focuses on a different aspect of physics, such as heat, light, or electricity and contains several stories that show how animals use those forces to survive and reproduce. My favorite was the story of Japanese honeybees, who use the body heat from hundreds of workers to prevent an attack from giant hornets.
The book is great for anyone who is interested in animals or physics but might be intimidated by the thought of lots of scientific terminology. The authors' humorous tone and obvious love of nature keep this from reading at all like a textbook. It's a very fun way to learn about why and how animals do what they do.
