This book was ten years in the making but I finally finished it! It's a collection of the top 50 most popular articles from my website "Science Questions with Surprising Answers," with each article extensively expanded and edited. This book also contains completely new content that is not available on my website: a completely new question and its answer, the question popularity rankings data, a section on the historical background of my website and this book, a large glossary of terms, and a humorous and useful pop quiz at the end. This book is dense with advanced scientific information and is not a children's book. The intended purpose of this book is to present interesting, enlightening, little-known scientific information to a general audience. For this reason, this book contains no mathematical equations or technical diagrams. It does contain detailed explanations and examples. I was surprised with how well the book turned out, so I heartily recommend it to you.
