This is one of the most exciting books I ever read - but remember - It's all about mathematics.

A fantastically entertaining and educational book about the quest to solve the oldest math problem: Fermat's Last Theorem. The intrigue, mystery, and drama surrounding the famous theorem without a proof (but that Fermat had said he had a proof for, just not enough space to write it in the margins)
Show More
is exciting enough. All the math greats who have attempted to solve it but come up a little short, or a lot short.

But it's much more than that, since the final proof of Fermat's Theorem involves so many other math concepts. This book starts and ends with Fermat, but in the middle it is more like a grand tour of all the mathematical developments that make the proof even possible. It's interesting to read about all the different dead ends and other productive findings (that had tangentially made it a little more possible to solve Fermat, but whose main contribution was in some other area). Also, reading about Galois's amazing life always makes me giddy. I mean, I've read about him before, but his story is just so crazy--math genius turned revolutionary thrown in jail involved in affair ends in duel, scribbles out his last thoughts the night before he dies... amazing.

But don't expect to understand how the proof actually works by the end. The proof itself is over 100 pages, so there is no way a normal non-math genius can understand it. But you will get a general idea of the approach/trajectory/style of the final beast. Also, some of the math concepts leading up to it are quite easily comprehensible. I wouldn't recommend this book to a math whiz... it's more of a fun read for the layperson.

It would ultimately be more satisfying if the proof were a short elegant thing that didn't involve latest groundbreaking discoveries in math. But maybe the bright side is that we can still wonder about Fermat's original (alleged) proof that was never written down. It had to be different from Andrew Wile's proof; does it exist? Or was Fermat bluffing? Or did he make an error in his proof?

Most people are familiar with the Pythagorean Theorem which describes a right triangle: a^2 b^2 = c^2. However, what you may not know is that Pierre Fermat claimed back in the 1600s to be able to prove that a^n b^n = c^n has no whole number solutions for n > 2. Trial and error suggests this to be

true, but for over 350 years, no one could prove it. This is the story of the equation and those who worked towards the eventual solution in the early 1990s, from Pythagoras through Andrew Wiles, who published the final proof. His proof is complicated enough that I suspect Fermat's proof was flawed, but it makes for a surprisingly engrossing read all the same. There are tons of names and personal stories in this book, and though they often feel tangential, every single person discussed has great bearing in one way or another on the solving of Fermat's Last Theorem. One doesn't usually equate mathematics with drama or suspense, but both are present here. Definitely recommended for anyone with even a passing interest in math or history.Note: The UK version of this book, which I have, is titled Fermat's Last Theorem. The American version is called Fermat's Enigma. There is also another book called Fermat's Last Theorem which was written by Amir D. Aczel. Confusion abounds.

Five out of ten.
Cambridge mathematician Andrew Wiles announced a solution for Fermat's last theorem in 1993 but after a flaw was discovered in the proof, Wiles had to work for another year--he had already laboured in solitude for seven years--to establish that he had solved the 350-year-old problem.

I have never before read a non-fiction book that had me turning the pages with such enthusiasm. The author's ability to turn the story of a math problem into such an extraordinarily entertaining and educational tale is quite impressive.

A great change of pace: the history, challenge and success of solving Fermat's Last Theorem: x^n + y^n = z^n cannot exist for whole numbers where n > 2. While Fermat declared this, he never published his "truly marvelous proof" and for centuries, mathematicians have been trying to prove or disprove

Fermat's Last Theorem begins with Pythagoras, goes through Fermat's positing of his theorem, the attempts by Euler and others to solve it, and culminates with Andrew Wiles's solution. It is generally entertaining and has the occasional equation, with a few more in the Appendix. But most of the

relatively light analytical machinery in the book is devoted to ancillary problems or general illustrations, Singh does not even go beyond an extremely superficial description of the main feature of Fermat's proof in the case of n=4. Instead a lot of the space is filled with detours that are often found in these sorts of books, from the role of women in French mathematics in the 19th Century to the puzzle fad in the early 20th Century. In that way this book fell short of Singh's Big Bang which felt more focused and a little more thorough in trying to describe how scientists discovered what they did about the big bang.

This one is the sixth book in the Stranger Than Fiction series that I'm now over halfway through (and kind of looking forward to finishing purely because it'll give me some room on my bookcase for some of the other piles of books I'm trying to get through).

I'll admit it, I wasn't really looking
Show More
forward to this book. I did consider skipping it, I really would have if I wasn't so obsessive compulsive that I really have to read all of the books in the set (in numerical order). But I read the back and decided to give it the benefit of the doubt, I mean, surely I was just feeling unenthusiastic because of the subject matter; maths and I have never really gotten along very well.

I'm the girl who once got a grand score of 26% in a maths test (and was going to be refused entry into the GCSE maths class). I managed to overcome this, scored a 1 at Standard Grade (thank you Scottish education system) and then decided to quit while I'm ahead. Ironically, since giving up maths, I've become far more interested in it. I like discovering little mathematical tricks and quirks; my doodles at work often incorporate visual representations of the fibonacci sequence (yup, I'm a geek).

So I decided that actually, I might just fall in love with this book. Plus the blurb on the back said that you didn't need to be good at maths to read it. It really sounded like something I could get into. Plus, the day I started reading it was the day that the news was focusing on the fact that numeracy standards have slipped and many people can't do basic maths problems. It meant I could sit feeling smug and intellectual while I was watching it. History, maths, a centuries old puzzle; by the time I started reading it, I'd really talked it up in my mind.

Unfortunately, after all that, it was a bit of a let-down.

Despite the assertion that you didn't need to be a whizz at maths to read the book, you kind of did. To begin with I was kind of expecting the book to be a bit like those The Knowledge books (the general knowledge versions of the Horrible Histories series). It seemed to have a bit of a sense of humour and there were photos and diagrams (all reproduced very well I have to note, considering it was all black and white).

But I felt like I was missing huge chunks of the plot, there were aspects of mathematics which were explained in the minutest of detail, while other bits which were important to the solution on the Theorem were sort of glossed over. I don't think I ever truly understood the concept of the 'proof' anyway. Plus, you knew the outcome from the very start, it was going to be solved. I wonder if there could have been a better way of structuring it, considering the fact that the events of the book were highly publicised at the time it would have been tricky.

There were other bits of the history of the Theorem that I was a bit more interested in, and there was so little of the book which was actually devoted to Andrew Wiles' role in the discovery of the solution that I would have quite happily read about all the other people, rather than him. I'd quite like to know more about some of the other's involvement.

I did get through this book quite quickly, though it was partly because I just wanted to get to the end. I kept on hoping that I would get to a point where I would really enjoy it and everything would come together, but it never really happened. I'm sure someone more mathematican than me would enjoy the book more but it certainly hasn't inspired me to track down more maths-themed reading material!

A mathematicians nightmare; a mathematicians dream. I've seen a documentary of the story but found the book immeasurably more enjoyable. Anyone who puts in that amount of dedication and sheer hard graft deserves the utmost admiration. A thoroughly entertaining read.

In about 1637, a French mathematical genius named Pierre de Fermat wrote in the margin of his copy of Arithmetica by Pythagorus, that he could prove that there were no solutions to the simple variation on Pythagorus' Theorem, az + bz = czwhen a, b, and c are integers and z is larger than two. In

over three hundred fifty years since then, the greatest mathematicians attempted to prove or disprove this little conjecture (or even to prove that no proof is possible). Students of science will recognize many of the famous names involved in the quest to solve "Fermat's Last Theorem", including Euler, Gauss, Lagrange, Cauchy, and Hilbert. Fewer will be aware that one of the most fruitful attacks on the problem was made by a woman named Sophie Germain, who concealed her gender in order to achieve credibility for her work. The recent solution of the puzzle by Andrew Wiles was the impetus for the PBS Nova program, "The Proof", which is based on Singh's work. If a book about an equation sounds pretty dry to you, this one is not! Singh has written a wonderful, engaging chronicle that brings together a huge fraction of the history of mathematics, and illustrates beautifully the utility of pure research. This is one of the best science books I've read this year.

"My butter, garcon, is writ large in!"
a diner was heard to be chargin'.
"I HAD to write there,"
exclaimed waiter Pierre,
"I couldn't find room in the margarine."

Ever since I recently stumbled upon the documentary called 'The Proof' I've become extremely interested (almost obsessed) in Wiles's proof of
Show More
Fermat's last Theorem and have been searching for a good book that would provide me with a real, mathematical explanation of it (mainly the connection between modular forms and elliptic curves), because the documentary was rather simple and basic. Unfortunately, so was this book and my quest continues.

Nonetheless, this book is very interesting and well written, and shows you how many things that appear to be simple and almost intuitive can be incredibly complex (that's what's so beautiful about math). In situations like this, people always tend to give all the praise to people like Andrew Wiles, without realizing on how much work and discoveries made by other people his work relies on. And even though Wiles deserves all the fame and recognition he can get for his persistence and determination, it's nice to see all the other great mathematicians who greatly contributed being mentioned. Like old saying goes: nanos gigantium humeris insidentes, and if anything, by showing how complex the proof is, it leaves you wondering, did the Fermat really have the solution?

If you are only slightly interested in mathematics and were just curious about this certain topic and ideas on which the proof was based on, or are looking for a good place to start, I would definitively recommend this book. But to be fair, you can get all of that by watching previously mentioned documentary and it would cost you much less time. On the other hand, if you want something more complex and mathematical, you won't get it here.

When Andrew Wile came through with his proof in 1993, I was flabbergasted. In my undergraduate and graduate days, this was it, THE prize in mathematics. The fact that there are two popular accounts on this topic is a tribute to how special an achievement proving Fermat's Last Theorem has become.
Show More
Prior to to the solution, there is at least one book for the layman that Eric T. Bell had written that illustrates the difficulty of the problem.

The achievement must be placed in historical context in order to better appreciate the amount of work and innovation it took to finally prove the theorem.

Both Singh and Amir Aczel wrote very good accounts of the process of solving the problem. They both did a good job of summarizing the history of the problem, they followed through with the building of the solution through each time consuming pain staking step. Indeed the solution is a literal accumulation of important results from many mathematical developments from over the past century. Each one of the steps illuminating the path toward the final proof. The solution encapsulates some of the most innovative solutions to mathematical problems that are seemingly unrelated to Fermat's Last Theorem.

It seems to me that Singh did a more thorough job of explaining the proof. The pace was a bit more leisurely and collegial. Aczel's account seemed more rushed, less considered, and had more of a rush to publish flavor. Not that is was a bad account.

I think that Singh had a more thorough understanding of the history of the problem because he took more time to set up the problem in its historical context. His explanations were also more detailed and better thought out for us amateur mathematician, who understand the fundamentals but not the details of rigourous proof.

Regardless, it was a treat to read and gave me a rush of discovery that usually comes with finishing a good murder mystery rather than an account of a mathematical achievement.

I love this book - it reads like a mystery full of obsessive people trying to solve a problem. I liked the math, and while the author, while not a mathematician, manages to simplify it to the point where a non-math person might understand the underlying logic.

The story is full of odd characters,

many of them obsessive. Most of them not likeable (which adds to the story). The story of Andrew Wiles, the man who finally cracked Fermat's Last Theorem, is quite good, and is the reason this book was written, but is really only a small part of this tale. It is written as part of the overall history, not just a major part of it.

While the book is about the path to Fermat's Last Theorem, but because so many new ideas came about from the path of solving it, this book can be seen as a brief history of math. Highly recommended if you like pop-science type books and mathmatics, but without all the hard stuff.

What particularly impressed me was how Singh explained the maths. He keeps the notation to a minimum and has a particular way of introducing news ideas (you’ll see what I mean if you read it) so that even someone like me whose brain just doesn’t work that way can follow it. Quick to read, but must have taken ages to get right on the page.

“The definition of a good mathematical problem is the mathematics it generates rather than the problem itself.”

Fermat's Last Theorem states that: xⁿ yⁿ = zⁿ has no whole number solutions for any integer n greater than 2. Simon Singh fashions the quest to solve this 350-year-old
Show More
mathematical enigma into a compelling story. In the 1630s, when Pierre de Fermat scribbled a note on a page of his copy of Diophantus’s Arithmetica, stating (in Latin) his theorem and indicating “I have a truly marvelous demonstration of this proposition, which this margin is too narrow to contain.” Singh takes the reader through a series of minibiographies of past mathematicians, ultimately arriving at Andrew Wiles, who spent over eight years developing the 130-page proof.

Along the way, the reader will learn a great deal about number theory, logic, and the rigorous standards required to achieve an absolute proof. This book covers a wide variety of people and their contributions over the years, such as Pythagoras, Leonhard Euler, Sophie Germain, Gabriel Lame’, Augustin Cauchy, Ernst Kummer, David Hilbert, Kurt Godel, Alan Turing, Goro Shimura, and Yutaka Taniyama.

The highlight of the book is, of course, Andrew Wiles who discovered Fermat’s Last Theorem at the age of ten, and dedicated himself to figuring out a proof, no matter how long it took. Wiles decided to keep his work secret and work alone in his attic. “You might ask how could I devote an unlimited amount of time to a problem that might simply not be soluble. The answer is that I just loved working on this problem and I was obsessed. I enjoyed pitting my wits against it.”

We learn about the Shimura-Taniyama conjecture, and the relationship between elliptic curves and modular forms. Singh never gets bogged down with calculations – they are instead included in the Appendices. I have a background in mathematics, so this type of subject matter appeals to me, but I daresay it is not required to enjoy this story of challenge, perseverance, and discovery.
