“Delightful . . . easily digestible chapters include plenty of helpful examples and illustrations. You'll never forget the Pythagorean theorem again!”—Scientific American Many people take math in high school and promptly forget much of it. But math plays a part in all of our lives all of the time, whether we know it or not. In The Joy of x, Steven Strogatz expands on his hit New York Times series to explain the big ideas of math gently and clearly, with wit, insight, and brilliant illustrations. Whether he is illuminating how often you should flip your mattress to get the maximum lifespan from it, explaining just how Google searches the internet, or determining how many people you should date before settling down, Strogatz shows how math connects to every aspect of life. Discussing pop culture, medicine, law, philosophy, art, and business, Strogatz is the math teacher you wish you’d had. Whether you aced integral calculus or aren’t sure what an integer is, you’ll find profound wisdom and persistent delight in The Joy of x.

Most Helpful Customer Reviews
I bought this to read on my NOOK, but was unhappy with the way equations were displayed (it IS a math book). It seemed that they tried to left-justify equations but sent them about 1/2 inch off the edge of the display. From the context I could usually figure out what was missing, but it was annoying.
As has been said by the first two reviewers, the ebook version of this puts the math examples partially off the screen, rendering them illegible. One star, untill someone fixes the formatting problem that the math examples have. I've notified the publisher (but got no response). I've called B&N customer service but was told it could take 3 weeks or such to be remedied. This is the first ebook that I ever paid for. Not a good experience, B&N.
Example equations not formatted properly and fall off the edge of the page. Changed font size and turned publisher defalts on and off, still not good. Why doesn't anyone do quality check. Could be good but pretty worthless if you can't follow the examples.
I think it is sad that this book is getting poor reviews because of technological issues with the Nook. Hopefully these issues reflect how valuable an actual BOOK really is and how pathetically reliant our society is on technology. Go out and buy this book! Steven Strogatz is an incredible mathematician with a unique gift for taking the cold hard facts of mathematics and showing his students and readers just how beautiful the world of math really is. Whether you are a student, a lover of numbers, or even hated math in high school, you will love this book!
I am very disappointed. I bought the version for the Nook at only a $3 discount from the paper version even though there is no cost for printing, shipping, storing, or clearing out remaindered copies. And what did I get for that? Many of the illustrations are too small to be easily understood on the Nook, and some of the mathematical symbols in the text translate to a '?' in a grey box because the Nook doesn't understand them, rendering the accompanying text meaningless unless you are already in the know. I don't think they did any editing or formatting for the digital version at all. The book itself is wonderful but I wish I paid the extra $3. And I am sure that, if I had, the profit margin on the sale would have been significantly less.
Buy the paperback. You won't be disappointed.
I really want to read this book but at $14.85 I'll wait until the formattimg has been corrected.
I'm eager to read this; the sample is quite inviting. But what is the status of the reported format issues?
I enjoyed this book as an overview of mathematics - where it came from, how it is used (often in ways I had not recognized), and why I should care. I bought it to have as a reference and share with others.
However all suggest get paperback or from library. Will do
Fun series of essays on mathematical topics. The author's take on the Hilbert Hotel was the clearest explanation of the differences between infinites I have read. I read this book on my Nook, and experienced no formatting issues; those of you "waiting for the formatting to be corrected" need wait no longer!
I read the book from front to back and it is worth the read. Try it for yourself and take it for a spin at your local library! You'll be glad to add it to your book collection.
I would like to purchase this book for my Nook, but was put-off by the comments on formatting. As soon as the formatting is corrected I would purchase it.
