"I have discovered a truly marvelous demonstration of this proposition which this margin is too narrow to contain."

With these words, the seventeenth-century French mathematician Pierre de Fermat threw down the gauntlet to future generations. What came to be known as Fermat's Last Theorem looked simple; proving it, however, became the Holy Grail of mathematics, baffling its finest minds for more than 350 years. In Fermat's Enigma--based on the author's award-winning documentary film, which aired on PBS's "Nova"--Simon Singh tells the astonishingly entertaining story of the pursuit of that grail, and the lives that were devoted to, sacrificed for, and saved by it. Here is a mesmerizing tale of heartbreak and mastery that will forever change your feelings about mathematics.

Simon Lehna Singh,(born 1964) is a British Indian author of Punjabi background, who has specialised in writing about mathematical and scientific topics in an accessible manner. He is the youngest of three brothers, his eldest brother being Tom Singh, the founder of the UK New Look chain of stores.

His written works include Fermat's Last Theorem (in the United States titled Fermat's Enigma: The Epic Quest to Solve the World's Greatest Mathematical Problem), The Code Book (about cryptography and its history), Big Bang (about the Big Bang theory and the origins of the universe) and Trick or Treatment? Alternative Medicine on Trial (about complementary and alternative medicine).

He has also produced documentaries and works for television to accompany his books, is a trustee of NESTA, the National Museum of Science and Industry and co-founded the Undergraduate Ambassadors Scheme.

In 2008, Singh was sued for libel by the British Chiropractic Association for criticising their activities in a column in The Guardian.[1] A backlash to the lawsuit is occurring, with Nature Medicine noting that the case has gathered wide support for Singh from thousands of scientists, journalists and parliamentarians, as well as prompting calls for the reform of libel law.
