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

Very little is known about the life of the man we now refer to as Fibonacci. He was born Leonardo Bonacci in Pisa, Italy, around 1170 AD. Leonardo was the son of a customs agent and spent some time interacting with Muslim merchants, where ...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
Most of us know Fibonacci (pronounced as fi buh naa chee) only for the Fibonacci Series. I guessed, the book will be only about Fibonacci series but was very much surprised as I progressed. The Fibonacci series comes only in the last chapter.
It's interesting to know that his real name was Leonardo Pisano and was very famous for his book Liber abbaci. This book was the first to help the me ...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
The book centers on Leonard of Pisa, better known as Fibonacci, and his ground-breaking work of mathematics, Libe ...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
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
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
