GIVEAWAY: The Mathematics of Various Entertaining Subjects

This week we’re giving away a hardcover copy of a great book to one lucky reader. To enter Math Blog’s July giveaway, please follow the instructions below.


For this giveaway, the prize is a copy of the book, The Mathematics of Various Entertaining Subjects: Research in Recreational Math.

There are a couple of cues that this book is not quite what it seems. First, it’s a $75 USD book, which is unusually high for a book on puzzles. Then there is that word, “research” in the tagline.

If you weren’t paying attention to those two cues, you might be deceived into thinking that this is an ordinary book that explores some common puzzles and games, and which shows you how to solve them with elementary mathematics (the crosswords and cards on the cover only add to that possibility).

The truth is that there is so much more to this book than meets the eyes. Yes, it talks about puzzles and popular games. Yes, it shows you how to solve them. Where things get really interesting however, is that the the ideas are stretched further into new theorem territory.

For example, at some point this book explores the familiar Tower of Hanoi problem. I mean, what more is there to say about that problem? It turns out there’s a lot, if we consider, as the authors did, the approach to solving the problem via random moves. And from there, note how the problem can be solved via a network of electrical resistors.

This book has impressive mathematical rigor. To what degree? It is essentially a collection of 17 research papers on the subject of recreational puzzles, authored by a couple of dozen well-established mathematicians. The writing remains clear and approachable across the board, but you’re also looking at some real math within.

I also appreciate that it’s a beautiful math title that includes numerous, often colorful, illustrations. In short, it is a remarkable book and we are happy to give a copy to one lucky winner. Join the giveaway below.

We are using the Rafflecopter widget below. If you participated in our raffles before, you can skip the instructions and go straight for the widget.

The widget will ask you to log in by providing your name and email (or through Facebook).

Once you’ve logged in, you’ll be asked to subscribe to our mailing list. You’ll be able to do so by simply clicking the checkmark, which you can also click if you are a subscriber already.

Note that all of these additional tasks are optional. Though, they can help your odds and they don’t take much time to complete.

At the end of Tuesday, July 19, 2016 (at midnight PST, so technically July 20th), the giveaway closes and a winner will be selected randomly from all the entries. The more entries you have out of the possible 21 entries, the greater your odds.

The widget will show you how many entries you have claimed and how many entries there are in total, as shown in the sample image below.

Raffle explained

The winner will be contacted within 48 hours by email, and arrangements will be made to deliver the book to the winner’s physical address. Please note that in order to avoid unfair entries, the randomly selected winner’s entries will be verified to confirm that the actions were actually taken. If not, then a new random draw will be executed.

Best of luck!
