Fermat’s Last Theorem [Fermat's Enigma] – Simon Singh *****

Just as the US publishers of Harry Potter and the Philosopher’s Stone reckoned the US public couldn’t cope with the word ‘philosopher’ and changed the title, this is calledFermat’s Enigma in the US (it could also be because of another book of the same name by Amir Aczel). But crazy assumptions from publishers apart, it’s the superb story of a bizarre little problem that no one could solve until the ever-wily mathematician Fermat scribbled in a margin that he had a wonderful solution, only there wasn’t room to write it down.
Fermat may well have been boasting, but it threw down a gauntlet to hundreds of mathematicians who were to follow until it was finally achieved in the 20th century. Don’t worry if the maths doesn’t interest you – the story will, both in its historical context and in the insight into the work and nature of modern mathematicians.
In some ways the star of the book is Andrew Wiles, the British Mathematician who pretty well single-handedly cracked the problem with an unusual level of secrecy, rather than the typical sharing approach of the profession. But equally it’s Fermat himself.
Whether or not Fermat actually had a solution is a moot point – but he certainly didn’t have Wiles’ complex approach. In fact it seems so difficult to come up with a straightforward solution to this problem that Fermat has to be more than a little doubted.
Like all the best popular science books – and this certainly is one of the best – it brings in a whole range of extras historically and mathematically to add to the fascinating cast. What can I say? Buy it!

Community Review – Katy
I am 12 years old and I love maths. This book was amazing! It is the best book I have ever ever read. I really enjoyed all of it. I especially liked the bits with examples in because it helped me to understand more because I am doing my GCSE in maths in 4 months. It was fascinating to learn about the theorem and the story behind it. It tells you about lots of different people who have attempted to prove the theorem. It also talks about lots of different areas of mathematics associated with the theorem that do not even sound remotely similar. It is amazing to think that such a simple theorem has taken so long to solve – 358 years in fact. This book has been so inspirational to me. It has made my passion for mathematics stronger. I would strongly recommend it to anyone. You will not be able to put it down!!!!!!!!
Additional Review – Stephen Goldberg – ****
Fermat’s last theorem was that a certain equation, under certain circumstances, had no possible solution. This theorem was finally proven in 1995 by mathematician Andrew Wiles. What made Fermat’s last theorem so intriguing to mathematicians was that Pierre de Fermat, in 1637, claimed to have proven it but left behind no written proof. Since that time and until 1995, mathematicians around the world have been trying to prove this theorem. It is not even known if Fermat himself actually proved it. The object of this book was to explain how this puzzle was finally solved. But the book is not just about Andrew Wiles. Author Simon Singh takes the reader through a fascinating tour of the history of mathematics before delivering the solution to us.
On his way to proving Fermat’s theorem, Wiles used a variety of techniques developed by earlier mathematicians. When Singh takes us though Wiles work and the use of earlier mathematical tools, he takes extensive detours to give significant biographical information on these earlier mathematicians. In this, Singh did a most admirable job. The book starts with Wiles’ presentation of his proof in 1993, but quickly detours to discuss the Greek mathematicians Pythagoras and Euclid. As Singh leads us through mathematical history he also pays significant attention to notable mathematicians Leonhard Euler (1707-1783), David Hilbert (1862-1943), and Alan Turing (1912-1954), among others. Particularly interesting was the chapter “A mathematical disgrace” where Singh discusses the difficulties faced by women mathematicians, most notably Sophie Germaine (1776-1831) and Emmy Nother (1882-1935). Also interesting was how Wiles worked in almost complete seclusion for a number of years. After Wiles presented his proof in 1993, errors were found, and he struggled for another two years before finally completing his work.
Where the book fails is in trying to actually explain number theory. There is a lot of math in this book, some of it relegated to appendices at the end. Very difficult to understand were E-series and M-series. Singh also failed to adequately explain mathematical techniques such as the method of Kolyvagin and Flach or the Taniyama–Shimura conjecture. If the objective of the book was to actually explain the proof of Fermat’s theorem then it fails as I understood it no better after having read the book than before. Where the book succeeds is in explaining how mathematicians build on other mathematician’s work and how a proof in mathematics, based on logical reasoning, is conceptually different than proof in other sciences that are based on experimentation and observation. The writing style was very accessible and easy to understand (aside from the math) and the biographies he writes are fascinating. Overall, this book was well worth reading for anyone interested in the history of science or mathematics.

The Feed (SF) - Nick Clark Windo ****

Ever since The War of the Worlds, the post-apocalyptic disaster novel has been a firm fixture in the Science Fiction universe. What's more, such books are often among the few SF titles that are shown any interest by the literati, probably because many future disaster novels feature very little science. With a few exceptions, though (I'm thinking, for instance, The Chrysalids) they can make for pretty miserable reading unless you enjoy a diet of page after page of literary agonising.

The Feed is a real mixture. Large chunks of it are exactly that - page after page of self-examining misery with an occasional bit of action thrown in. But, there are parts where the writing really comes alive and shows its quality. This happens when we get the references back to pre-disaster, when we discover the Feed, which takes The Circle's premise to a whole new level with a mega-connected society where all human interaction is through directly-wired connections… until the whole thing fails …

Everything You Know About Space Is Wrong - Matt Brown ****

What we have here is a feast of assertions some people make about space that are satisfyingly incorrect, with pithy, entertaining explanations of what the true picture is. Matt Brown admits in his introduction that a lot of these incorrect facts are nitpicking - more on that in a moment - but it doesn't stop them being delightful. I particularly enjoyed the ones about animals in space and about the Moon.

Along the way, we take in space exploration, the Earth's place in space, the Moon, the solar system, the universe and a collection of random oddities, such as the fact that Mozart didn't write Twinkle, Twinkle Little Star. Sometimes the wrongness comes from a frequent misunderstanding. So, for example, Brown corrects the idea that Copernicus was the first to say that the Earth moves around the Sun. Sometimes there's some very careful wording. This is used when Brown challenges the idea that the Russian dog Laika was the first animal in space. What we discover is that, i…

Dark Matter and the Dinosaurs - Lisa Randall ****

I did my PhD in galactic dynamics - which is an awkward subject when people want to know what its relevance to the 'real world' is. So I was excited when Clube and Napier's book The Cosmic Serpent came out, around the same time, because it provided me with a ready-made answer. It argued that the comets which occasionally crash into Earth with disastrous results - such as the extinction of the dinosaurs - are perturbed from their normal orbits by interactions with the large-scale structure of the galaxy.

I was reminded of this idea a few years ago when there was a flurry of media interest in Lisa Randall's "dark matter and the dinosaurs" conjecture. I was sufficiently enthusiastic about it to write an article on the subject for Fortean Times - though my enthusiasm didn't quite extend to purchasing her hardback book at the time. However, now that it's out in paperback I've remedied the situation - and I'm glad I did.

Dark matter is believed to exi…
