From the Contributor
The beginning of the computer age was in antiquity. Cryptic diagrams, mathematical riddles, astronomy, etc. explored in this book.
This book might be enjoyed by any avid sleuth of unsolved mysteries or fan of "Indiana-Jones" type mysteries. The topics range over calendars of mesoamerica to the Pythagorean Equation and a number of other esoteric, technical topics that would especially be of interest to high school math majors and/or computer science majors.
