Awesome book! A lot of fun. As a caveat to the reader, getting to Professor Benjamin's level will take a lot of time and practice and one cannot reap the seeds sown in this book without both: time and practice.

That being said, this book was a fun read, full of insightful tips, humor and cool stories. Some tricks I learned was how to square any number, multiple digit math, within respectable limits, in my head, and finding out which day of the week any date is.
