riddlesI don’t even know what to say about this book.  It is a book of paradoxes – a paradox is “conflict between reality and your feeling of what reality should be like” and has a bunch of brain teasers in it.  A lot of them made me crazy trying to figure it out.  A lot of them blew my mind.   I really don’t know how to write about this book – but if you want your mind blown then you have to read it.  If you’re interested in Math and crazy brain teasers you have to read it.  The only notes I wrote about this book was “mind blown”.  I can’t even explain it but these paradoxes definitely made me rethink everything I thought I knew about math!

I received a free e-copy of this book in order to write this review. I was not otherwise compensated.

“Mr. Northrop writes well and simply. Every so often he will illuminate his discussion with an amusing example. While reading a discussion of topology, the reviewer learned how to remove his vest from beneath his jacket. It works every time.” — The New York Times
