About the Author
Born in England in 1947 and living in America since 1987, Keith Devlin has written more than 20 books and numerous research articles on various elements of mathematics. From 1983 to 1989, he wrote a column on for the Manchester (England) Guardian.

In about the year of 1170 a man named Leonardo was born in Pisa. Opening a book he wrote in 1202 he referred to himself as Leonardo Pisano, Family Bonacci, from this Latin phrase filus Bonacci his present day nickname “Fibonacci” was coined by a historian in 1838.
Fibonacci is usually remembered only in connection with the ‘Fibonacci sequence’ however, in this fine book Keith Devlin carefully outlines his role as a towering figure in the movement of Hindu-Arabic numerals and show more arithmetic from the southern Mediterranean into Italy where it spread into Europe.
The system was known in Italy before Fibonacci was born but it had was little used and not seen as being of value. It was the achievement of Fibonacci in his books to describe the system in terms of the problems encountered by merchants. He provided page after page of problems that involved trade, the measurement of land, the division of profits and the exchange of one form of money for another. Each problem was carefully worked out with the problem described in the text and the numbers presented in red in the margin.
Fibonacci had written the first practical math textbook and it was copied over and over again by other authors. With real world examples such as “On finding the worth of Florentine Rolls when the worth of those of Genoa is known” he had written the first book on the Hindu-Arabic system that had popular appeal.
The type of book that we all use to learn basic arithmetic is the direct descendant of this type of writing. The story of the development of math and math learning is very well told in this most enjoyable book. It in no way requires a math background or skills to read and enjoy. I recommend it to anyone who likes a good story of how our world came to be.

This review was written for LibraryThing Early Reviewers.The Millennium Problems: The seven greatest unsolved mathematical puzzles of our time by Keith J. Devlin
Keith Devlin takes on a daunting task in The Millennium Problems: explain the problems that the Clay Mathematical Institute in 2000 labeled the seven most important unsolved problems in modern mathematics to an audience of non-mathematicians. Given the difficulty of this problem, Devlin succeeds as well as could reasonably be expected.
Devlin organizes the book from most comprehensible to least, beginning with the relatively straightforward Riemann Hypothesis dealing with the distribution of show more prime numbers (though ease in understanding is not ease in solving; this is the longest-standing of the Problems, first proposed in 1859.) He works his way through the classic algorithmic question of P vs NP and the Poincaré Conjecture (proved in 2006, after the publication of this book) to the utterly opaque Hodge conjecture, where he effectively throws up his hands in despair at even attempting to explain the problem.
The book assumes an interest in math (why else would anyone read it, after all?), but not much knowledge of the field. This was actually rather baffling; Devlin has no qualms about introducing the fundamentals of complex analysis or group theory, but doesn't assume the reader knows or remembers differential calculus. I thus found myself skimming impatiently at some points while being baffled at others. It's probably safe to assume that people who didn't take any math at all in college wouldn't touch this book, so why the coyness about high school calculus?
As a physicist and astronomer by training, it was difficult for me to understand why some of these problems matter. P vs NP is obviously tremendously important to modern computing, and the Navier-Stokes equations of fluid mechanics have clear real-world applications (and their inclusion in the list of problems validated my longstanding opinion that quantum mechanics and general relativity are childs' play compared to the terrors of fluid dynamics), but what will it actually mean, even to mathematicians, whether the Hodge conjecture is true?
This review may seem fairly critical, but overall The Millennium Problems is a very interesting read; the task it tackles may just be nearly as difficult as some of the problems it describes. show less

I clearly remember puzzling out the relationship between the numbers in the Fibonacci sequence back in grade school, so I was vaguely expecting a bunch of interesting number puzzles from this book. Instead, what I got was a fantastic historical and mathematical tour of Italy in and around the 13th century, and an appreciation for the revolution caused by the introduction of the numerals 0-9 and the new way of doing arithmetic.
While I had a vague idea that doing arithmetic with roman numerals show more was annoying, I hadn't really thought about how much easier it is to use 0-9. The introduction of the new math was totally revolutionary, affecting the complexity of trade in the newly emerging banking, and insurance industries. Like most brilliant new ideas, it was resisted (in some cases legislated against), and then eventually simply replaced the previous system to the degree that we don't even think about it anymore. Fibonacci is famous for publishing the first practical guides to using the new mathematical tools, and appears to be the direct ancestor of day's math textbooks. Devlin puts some translations of Fibonacci's solutions to example problems alongside the solutions that people today would be familiar with from a high-school math class, and it is shocking to see just how far we have come. If you're someone who doesn't like looking at equations, these are easy to skip past as they're simply for illustration...and I suspect that Fibonacci's approach to arithmetic might give you a whole new appreciation for them!
This was a great book. Nice and short. Devlin's style is easy to read and entertaining, and I learned a lot. I'm definitely planning to investigate some of his other books. show less

This review was written for LibraryThing Early Reviewers.I read books on the history of math because I am interested in how people think, not specially in math. This is a very touching book on how arithmetic was introduced to Europe in 1202 by Fibonacci, an Italian we know almost nothing about. At the eve of what was to become "global trade", arithmetic came just on time. What made it possible was the introduction of the numerals 0 to 9 and place value. This, Fibonacci inherited from India via the Arab world: he made popular what we now consider show more basic knowledge all over the world. It could be a dry book, it is not: under the bright, intelligent, incisive style of Keith Devlin, there is a lot of love and emotion, the ambition to correct a wrongdoing of history: if you know Fibonacci's name, it is probably for the wrong reason. The book tells you a lot on how people thought: how do you solve problems when you do not have mathematical symbols? Devlin guides us through some problem solving examples from the Fibonacci's book of calculation, I found this entertaining. I live in Savannah GA where no kid knows how to divide by ten, because teachers have forgotten the importance of place value: this is the kind of book that would remind them what arithmetic is about: it is the first step to democracy. show less
