The Man of Numbers: Fibonacci's Arithmetic Revolution
This was also a very educational read. I learned many facts about Fibonacci that I didn't know or wouldn't know to ask. Such as Fibonacci is not his real name, it's Leonardo (another talented Italian Leonardo). O ...more
Fibonacci was named Leonardo, and came from Pisa, hence his name in his time would have been "Leonardo Pisano" (Leonard from Pisa). The name "Fibonacci" comes from "Filius Bonacci ...more
I do not attribute it all to Devlin however. He chose a very difficult and hardly simple task. As Devlin himself admitted, there is scant history on Fibonacci the man, let alone his mathematics. Devlin must have had ...more

How about: This is not a book, it's an essay that was pushed far beyond its means. What's worse, the essay part lacks an effective argument.
Or: This is equal parts down-talking, back-tracking, bush-beating-around, and essay.
Or even: The total effect of reading this might be less effective and educational than reading the page on Wikipedia for Fibonacci.
Or maybe: I got this free, if I had to pay the $25 cover price for it, I'd be absolutely livid. I mean, I get ...more
The book centers on Leonard of Pisa, better known as Fibonacci, and his ground-breaking work of mathematics, Libe ...more
On the one hand, it deals with a fairly obscure branch of intellectual history and tries to do scholarly justice to the subject matter, with long quotations from mathematical texts and lengthy explanations of possible mansucript transmission. Yet the paucity of appropriate citations, the unecessary repetition, and the b ...more
Leonardo of Pisa, also known as Fibonacci, was a mathematician who seems to have been most responsible for popularizing Arabic numerals (which were actually thought up in India) and also for showing how arithematic and algebra could be done with them. Leonardo seems to have born in Pisa about 1170 and was still alive about 1240. He seems to have learned about Arabic numerals and the techniques of arithematic from Arabs when he was in the Algerian port of Bejaia (then called Bugia) where his fat...more

where the first two numbers are 1's and each succeeding number is the sum of the two previous. But Fibonacci was also the first European author to fully recognize the importance of Hindu/Arabic numbers, and he wrote a famous text: Liber Abacci, about their use. (This is properly translated as book of calculation, not book of the abacus; indeed, it shows how to replace a ...more
Detto questo, è un libro divulgativo interessante e mette in luce l'importanza di questo matematico, di cui generalmente si sa poco.
Parts of the book are less interesting. I ...more
What he has to say seems like it could fit in a much smaller work, but the math could easily be a much greater thing. For a popular audience, this is at once both too little and too much. But i ...more
As another reviewer put it:
"there just isn't as much substance to the book as I was looking for. There is a dearth of information surrounding Leonardo's life, and the author is forced to include chapters about Leonardo's potential sources and the other books written because of Liber Abbaci."
Leonardo is to Arithmetic as Steve Jobs and Bill Gate to Personal Computers
He was born in 1170, his father sent him to Bugia. Bugia was the port where european and arab merchants made their trades. Chapter 2 ...more
