Fun! This book is full of fun science and engineering jokes some of which I found hilarious and many of which were over my head entirely. It’s a collection of articles, essays, poetry and illustrations of a scientific nature most of which seem designed to amuse or share some sort of professional in-joke. I understood some of it and was totally lost with others. However, one of the great things about it is the cross-disciplinaryness of the whole thing. So, you get poems about the second law of thermodynamics or drawings about how to use a small dog to teach physics.
