This is a beautifully produced book. The front jacket is amongst the most attractive I have seen and the back cover is dense with quotations from reviews singing its praises, including one from a Nobel Laureate. Oh dear, how we can be deceived by outside appearances! The text contains so many errors, misleading statements and moments of such stupidity that to discuss them all would require a volume about equal in size to the original.
Let me take you through a few examples: -
Page 21. 41/12 is neither a square number nor an integer as claimed in the text.
Page 22. There is no contradiction in Fibonacci stating that the problem under discussion is indeterminate and for him then to give a (correct) solution to it.
Page 33. The proof of Property 2 given in appendix B is a proof by contradiction, not a proof by induction as stated.
Page 34. Many of the factors listed in Figure 1-9 are wrong. See, for example, the factors given for the sixth Fibonacci number.
Page 40. Figure 1-11 is confusing. What is the rectangle on the RHS supposed to indicate?
Page 48, Figures 1-14 and 1-15. Contrary to their captions, both would seem to contain an odd number of rectangles.
Page 49. Line 7 and line 18 are identical, lines 8 and 19, to which each is supposed to be equal, are not equal.
Page 49. Line 20. 1156 does not equal 342, and 342 is not the 29th Fibonacci number.
Page 51, last line but one. 520 is not the product of 18 and 29.
Page 56. The written summary of property 13 is wrong.
Page 80. Footnote should read `fourth difference', not `third difference'.
Page 82. Why express amazement that, in a table of differences for the Fibonacci sequence, each new line of differences repeats the original sequence. Give the way in which the sequence is generated, how could it possibly be otherwise.
Pages 91, 93 and 102. The term `left justified' has a different meaning on each page.
Pages 111 and 112. Having defined Phi such that 1/Phi = Phi - 1, the authors express amazement that their fractional parts are equal. They then expand each to 1000 DECIMAL PLACES to demonstrate this.
Chapter 3. The suggestion that the Fibonacci sequence is in some way connected to the powers of 2 and to the sequence of numbers generated by the partitioning of a circle, simply on the basis that all three sequences can be located in Pascal's Triangle, is nonsense.
Page 120. The claim that by replacing the `1' in the exact value of Phi with e^(i x Pi) establishes a deep and meaningful connection between Phi, Pi, e and i either the height of stupidity or a confidence trick.
These are not the worst examples, just a random selection from the first 120 pages. They keep on coming thick and fast throughout the rest of the book.
Any `general reader' who tries to follow the mathematical developments set out here will only have confirmed a belief that mathematics does not make sense. The authors and their publishers have done mathematics a grave disservice in having produced such a carelessly written and shoddily edited volume. This is terribly sad; if more care had been taken over researching, writing and editing, it could have been the best popular mathematics book in years.

There is a lot of good information here, where the maths is standard.
Unfortunately the book is very sloppily written and badly edited.
Some ideas are well referenced, but others are not attributed, like the Odom construction from the equilateral triangle in a circle.
It contains lots of errors and the usual extrapolations that are not valid.
For example, the nautilus shell is said to be golden section without any proof (it has nothing to do with the GS) and the cover perpetuates that myth.
The Art section is very bad with the usual chosing of data and stretching it to fit the hypothesis. Better to read Mario Levi's book to see why this is rubbish. This is in line with many poorly presented diagrams showing an editorial and author lack of visual sense. For example figure 2-22 is squashed horizontally.
There are lots of lists of what people say on the internet with no critical views as if they are trying to sell the book because of this popular view. This perpetuation of mis-information clouds one's ability to believe the rest of the book.
It's very sad that what is mostly a good collection is so shoddily presented and mixed up with great deal of wrong information.

The book provides much of the available information on the Fibonacci numbers. It starts with the life of Leonardo da Pisa, the man who first introduced the numbers to the world almost a thousand years ago. It describes the actual sequence, then demonstrates the connection that the numbers have to the natural, as well as to the world of the visual arts and of music. Even the stock market is not immune of the influence of the Fibonacci sequence.
What particularly impressed me about this book is the clarity with which the authors present the subject. Whether you are a mathematician or simply have an inquisitive mind, you will always know the exact meaning of the subject under discussion. In fact, you can skip the (sometimes) long mathematical formulae and still never lose track of the narrative.
A wonderful book that makes one ponder on the origin and significance of the created world. A must for mathematicians, scientists and generally educated individuals. A must also for those who believe that our universe and all its contents are only the product of a series of coincidences. These people may change their minds after becoming familiar with the Fibonacci numbers.

If you are looking for a book that describes real world examples of Fibonacci sequences, this is not the book to read. The book is simply a list of proofs and not written for the non-math oriented person. If you desire to know the `gist' of Fibonacci numbers, skip this book, and read a few web pages instead for a more condensed and broad review of their meaning and application.

It was very hard to assign a star rating to this book. There are thingss I like very much, and others I definitely do not.

On the good side, it is a very attractive presentation of the beautiful patterns appearing in the mathematics of the Fibonacci sequence. It is not quite as heavy on the mathematics as Dunlap's or Vajda's books (which may make it an easier read for those whose math isn't as strong as mine!) but what it does, it does very nicely, using tables and pictures to make the patterns very clear.

On the bad side, I wish the authors would not accept so credulously such myths as the one of Greek architect Phidias' using the golden section in his design (this has already been debunked by Livio) or the numerological nonsense promulgated by people who try to spread the idea that the Fibonacci sequence can be used to predict the stock market. People following such misguided ideas are likely to lose their shirts, so this sort of credulous myth-spreading is dangerous, not just bad judgment.

So how do you rate a book with so much good and so much bad in it? I've given it 4 stars because the good parts are so good. If the authors had spared us the myths, I would have given it 5.

The book is very interesting both for a technical reader and just a lover. It is easy to read, but has also some rigorous proofs in the appendix. The only limitation is that the book would have needed another revision before publication.

A great book. Has everything i would need for a research project plus so much more. The author did a great job.

The most intriguing number pattern in math is the Fibonacci sequence, a pattern which begins with two ones, each succeeding number of which is the sum of the two numbers immediately preceding it. And it's not just a mathematical incongruity, but occurs throughout nature itself, building the case for the mathematical basis of nature itself. Any college-level collection strong in science and nature - and many a public lending library- will find this a fascinating review of the history of the Fibonacci numbers and their applications to everything from nature to art and the stock market.

The book contains many interesting and unpredictable properties of the Fibonacci numbers. I learned a lot of new things about them.
