To Mock a Mockingbird

One of the best books I ever bought. Its exposition on combinatory logic using different birds species is perhaps a little eccentric, but it actually works amazingly well to explain the concept. Recommended for anyone who wants a gentle introduction to combinatory logic.

I gave this as a gift to my daughter in law. She and her brother really enjoyed it. Thought provoking I believe

If you like logic puzzles, this book is great.

One of the best books of puzzles!

It's an underappreciated book. The birds puzzles are a clever and gentle introduction to combinatorics. Sometimes funny and with clever dialogues, it is a really useful book that can actually be used for formal logic classes.

One of the most remarkable and fun books I've ever worked through. This book teaches combinatory logic by masking combinators as singing birds. You'll be hearing Turing birds sing and you'll be traveling to Godel's forest. Make sure to be prepared for your journey with a lot of paper and tea as this book will capture you once you start working through the problems. You'll be laughing along the way as you discover new birds and your mind will stretch a lot. If you've patience to work through all the chapters, you'll learn about Church encoding and Godel's incompleteness theorem in the end.This book is so fun that I've placed it #7 in my Top 100 Programming, Computer and Science books list:[...](If this link gets removed, google for >>catonmat top 100 programming computer science books<< to find my article.).

I enjoyed this book immensely, and if you like Smullyan's style, then you will too. However, I found some parts of it more difficult than other books I own by the same author. Perhaps the novice reader should choose a different book?
