I will be the first to admit that I'm not good at math. Despite taking Higher Maths in IB (I just practiced so many times that I somehow knew how to solve the question), I still didn't understand a lot of concepts. And despite all the quotes about how math was beautiful in my textbooks, I still just don't get it. And I suspect that this problem isn't unique to me a lone. So, I was really intrigued by the promise of this book to be a guided (and fun) tour of math.

Are you the type of person who spent hours on the bus on the way to school working out multiplication tables for prime numbers only? When you're having sex do you find that the earth may not move, but images of numbers and mathematical symbols appear in your head when things are going great? OK, I'm getting a little too personal here, but if you're a numbers geek, you'll love this book.

You wouldn’t know it, but maths permeates everything we do and touch. Your smartphone would not be able to operate without maths, nor would the internet. You couldn’t buy anything risk free if we didn’t have the primes. Things as unlikely as the correct time to flip a mattress, the number of people to date before settling down, the best path from A to B, that if you look hard enough you can see sine waves everywhere all have some element of maths in them.

I wish I could have read this book during that hell year of first year university, when I barely passed calculus despite devoting more time to studying it then the other 4 subjects combined (or maybe it just seemed like that -- very long nights in the library, writing out reams of papers of formulae, the table strewn with my hair and tears).
Now sufficient time has passed and, like childbirth, I forget the pain and remember only those good moments, the eureka! ones.

Struggling through several years of higher math in engineering school in the 1960s didn't engender a love of mathematics in me. It wasn't until years later that I began to value the beauty and elegance of mathematics. A big part of my appreciation came from mathematicians like Steven Strogatz who wrote about math for readers who appreciated the concepts but had no desire to wade into a morass of complex equations.

In The Joy of x, Strogatz has done a masterful job as our tour guide through the el

A wonderful book of short essays displaying the elegance of math in a grand and easily digestible format. This book started life as a series of columns in the New York Times as an introduction to and has been expanded on a bit. Each chapter is the length of a typical column, and while the book is by no means comprehensive, there are copious notes and reading lists in the back should one want to explore topics further.

The book starts with basics like numbers and addition and continues right on to

I know what "i" (make that italics) does to something in a practical manner now!!!! Took me twenty-eight years to make it 30 minutes into a book that explained it to me.. but.. I KNOW!! Wooohooooo

Really, I loved reading this book, it was a super fun journey. Now, I'm going to sit down and make a mobius strip with my five-year old daughter!!

I love this book. My only regret is that I couldn't read it in high school, when I was *actually* struggling with math. At this point (having degrees & math & math education & have spent over a decade teaching the subject and/or teachers of it), I read it more from the point of view of, "How could I use pieces of this with students and/or the teachers that I work with?"

In these 30 short essays--a couple of which I had read before in his Time column--Strogatz begins at the beginning (

Rare is the occasion to have math thrown at your brain in a direct and pedagogical manner after, say, college calculus. The Joy of X is math made quick and fun, replete with dad jokes, groaners that make an appearance at the close of each chapter. Typically, they reference a social touchstone that is out of date or just sort of lame. After a certain point, though, their earnestness infected my mind and I began to unironically enjoy them, even attempting to anticipate when, where, and in what for ...more

I applaud you, Stephen Strogatz, for truly putting the joy back in math! My life might have been very different if I had read this book in high school. Biology was my passion, but I avoided the field because of the math courses required for a bachelor of science degree.
My father was a calculus professor and he made math interesting and approachable. He died when I was 13 and afterwards numbers became a challenge because my teachers never explained them with flair and passion. My dad said, "If yo

Pretty dull. The book's structure parallel's that of a standard math education, and offers little added value. I wanted a greater appreciation of math's beauty, instead I god a folksy re-hash over concepts I was generally aware of, and competent and applying (the exceptions being topology, group theory, the hilbert hotel, and a few other odds and ends).

In the end, it wasn't worth my time.


Disclaimer: I have a math minor, so I know only enough math to be marginally dangerous.

This book is about math, but it doesn't have much math in it. So mostly it's pretty easy to read. It must have been very difficult to write about some complex math ideas for non-mathematicians! For the most part, Strogatz does a good job. There were, however, a few parts where I confess I couldn't be bothered to think hard enough to get through the little bit of math there was and I just skimmed those parts. ;) Other times, I felt that Strogatz lingered too long over an easy point. It's probably ...more

This is a delightful little book on mathematics. One of those rare, wonderful, popular math books. It was actually a gift for my nephew who started his engineering studies. After he was through reading it, I thought I'll give it a try myself! And the book was absolutely worth reading. Strogatz, whom I knew as a pioneer in nonlinear dynamics, chaos and synchronisation, has done a wonderful job of getting people interested in mathematics. The book touches upon some of the most important concepts o ...more

In this book Steven Strogatz makes a brief tour of many areas of mathematics. He starts that tour with the concept of natural numbers and approaches many subjects like arithmetics, geometry, trigonometry, algebra, calculus, statistics and so many other subjects in a simple but highly effective way. He didn't want a fat and huge book about maths or calculus for example and instead he preferred to make a simpler book destined to everyone where he makes an introduction to mathematics and explains ...more

This is a charming book that attempts to provide an understanding of Mathematics for pretty much anyone.
As one who has a strong background in Mathematics, I found it an easy read. I found it to be quite interesting, despite my already knowing quite a bit about the topics being covered. The writing style is light, engaging, even charming, and includes a lot of items that relate the Mathematics to the real world (something I find too many Mathematics courses seldom do)

Comecei o ano bem.

É um livro pra dar de presente a qualquer um que diga que acha Matemática difícil ou que não entende. Ele assume que tu não sabe nem o que é o assunto e conta a utilidade de várias subáreas, ensinando o básico e gerando curiosidade. Muitos dos conceitos que tive que aprender fazendo centenas de exercícios e quebrando a cabeça são explicados de formas extremamente didáticas.

Название не врёт - действительно, удовольствие.
От счёта рыбок до бесконечности, умноженной на бесконечность, ведётся повествование о различных областях математики.
В школе этот предмет был мне очень интересен, но до определённого момента. Когда начались логарифмы, первообразные и производные - все эти неосязаемые штуки, я перестала получать от математики удовольствие и сосредоточилась на умении решать уравнения и задачки (в конце 11 класса был обязательный ЕГЭ).

If I have read this book at school, my life would be a lot easier and I would not have to spend hours memorizing various mathematical theorems.

This is one of the few books that describes the abstractness of math concepts in an actually-accessible way. The descriptions of infinity and topology are perfect in their deconstruction of mathematical concepts to what they really are. Is math complicated? Yes. Are its core concepts difficult to understand? NO.

One of the more frustrating things I feel from the math side is when people say that proofs are too complicated. Usually they are only as complicated as the proof writer's style. If the w

I was a math major in college. I chose it for a major because the concepts of numbers and the relationships in the study of number theory fascinated me. Strictly speaking, I never had a job where I had to do any higher math, solve a quadratic equation, discuss or teach functions, trig, geometry, etc. But it did strengthen my ability to reason, look at ideas in the abstract and conceptualize a problem in real terms. It certainly helped me a lot in working with software development in one of my pr ...more

THE JOY OF X is an entertaining and insightful math book that doesn’t require much mathematical know-how or computation, just interest. It’s essentially a collection of essays, each one addressing a mathematical subject from a new and illuminating angle, all organized from the simplest to the most complex.

'The Joy of X' delivers on its title's promise to show the readers the joy of Mathematics. However, I believe that a little knowledge of Mathematics including Algebra and Pre- calculus will help in understanding the concepts in the book.
Strogatz does a great job of giving true life examples to illustrate complicated concepts and his writing style is inimitable; for example when he says statistics helps to "find the needle of meaning in the haystack of data."

After the first 2/3 of the book, I was prepared to give it a three star rating. While The Joy of X is well-written, educational, and entertaining, I really wanted Mr. Strogatz to go into more detail on the topics he covered. But as he reached more advanced and interesting topics later in the book, it became somewhat more satisfying. This book won't make you an expert on any of the mathematical topics covered, but you will learn some interesting new ways of thinking about the subject.

“Looking at numbers as groups of rocks may seem unusual, but actually it's as old as math itself. The word "calculate" reflects that legacy -- it comes from the Latin word calculus, meaning a pebble used for counting. To enjoy working with numbers you don't have to be Einstein (German for "one stone"), but it might help to have rocks in your head.” 10 likes
“let’s begin with the word “vector.” It comes from the Latin root vehere, “to carry,” which also gives us words like “vehicle” and “conveyor belt.” To an epidemiologist, a vector is the carrier of a pathogen, like the mosquito that conveys malaria to your bloodstream. To a mathematician, a vector (at least in its simplest form) is a step that carries you from one place to another.” 2 likes
