If you have questions or comments, please send me e-mail: davids@math.holycross.edu A Course on the Fibonacci Numbers During the spring semester of the 1994-1995 academic year I taught a course called "The Fibonacci Numbers". Some materials from that course , including the syllabus and some lecture notes, are available over the Web. I will probably teach the course again in the spring semester of the 1996-1997 academic year. Mathematical material Bob Devaney (a Holy Cross grad) of Boston University has some marvellous material on the Fibonacci numbers' stunning appearance in the Mandelbrot set In case you want them, here are the first 500 Fibonacci numbers, in blocks of 100: 0 to 99 100 to 199 200 to 299 300 to 399 ... 400 to 499 I have compiled a lengthy list of factorizations of Fibonacci numbers, which I am converting to HTML as time allows. Some of the entries in the lists are hotlinks to factorizations. Many of these computations were performed with the assistance of the symbolic computation package Maple This section will be worked on during February 1996. Please check back.

4. The Golden Ratio And The Fibonacci Numbers The Golden Ratio and. The fibonacci numbers. The Golden Ratio () is an irrational number with several curious properties. It can be defined as that number which is equal to its own reciprocal plus one = 1/ + 1. a Golden Rectangle, however, is an interesting exercise in the geometry of the Golden Ratio, as seen at right http://www.friesian.com/golden.htm

The Golden Ratio and The Fibonacci Numbers The Golden Ratio ) is an irrational number with several curious properties. It can be defined as that number which is equal to its own reciprocal plus one: . Multiplying both sides of this same equation by the Golden Ratio we derive the interesting property that the square of the Golden Ratio is equal to the simple number itself plus one: . Since that equation can be written as , we can derive the value of the Golden Ratio from the quadratic equation, , with a = 1 b = -1 , and c = -1 . The Golden Ratio is an irrational number, but not a transcendental one (like ), since it is the solution to a polynomial equation. This gives us either or . The first number is usually regarded as the Golden Ratio itself, the second as the negative of its reciprocal. The Golden Ratio can also be derived from trigonometic functions: = 2 sin 3 /10 = 2 cos ; and = 2 sin /10 = 2 cos 2 . The angles in the trigonometric equations in degrees rather than radians are o o o , and 72 o , respectively. The Golden Ratio seems to get its name from the Golden Rectangle , a rectangle whose sides are in the proportion of the Golden Ratio. The theory of the Golden Rectangle is an aesthetic one, that the ratio is an aesthetically pleasing one and so can be found spontaneously or deliberately turning up in a great deal of art. Thus, for instance, the front of the Parthenon can be comfortably framed with a Golden Rectangle. How pleasing the Golden Rectangle is, and how often it really does turn up in art, may be largely a matter of interpretation and preference. The construction of a Golden Rectangle, however, is an interesting exercise in the geometry of the Golden Ratio

5. Sacred Geometry Home Page Sacred geometry is an ancient art and science which reveals the nature of our relationship to the cosmos. Its study unfolds the principle of oneness underlying all creation in its myriad Interestingly, 5 (Platonic) and 13 (Archimedean) are both fibonacci numbers, and 5, 12 and 13 form a perfect right http://www.intent.com/sg

Sacred Geometry Home Page by Bruce Rawles In nature, we find patterns, designs and structures from the most minuscule particles, to expressions of life discernible by human eyes, to the greater cosmos. These inevitably follow geometrical archetypes, which reveal to us the nature of each form and its vibrational resonances. They are also symbolic of the underlying metaphysical principle of the inseparable relationship of the part to the whole. It is this principle of oneness underlying all geometry that permeates the architecture of all form in its myriad diversity. This principle of interconnectedness, inseparability and union provides us with a continuous reminder of our relationship to the whole, a blueprint for the mind to the sacred foundation of all things created. The Sphere (charcoal sketch of a sphere by Nancy Rawles) Starting with what may be the simplest and most perfect of forms, the sphere is an ultimate expression of unity, completeness, and integrity. There is no point of view given greater or lesser importance, and all points on the surface are equally accessible and regarded by the center from which all originate. Atoms, cells, seeds, planets, and globular star systems all echo the spherical paradigm of total inclusion, acceptance, simultaneous potential and fruition, the macrocosm and microcosm. The Circle The circle is a two-dimensional shadow of the sphere which is regarded throughout cultural history as an icon of the ineffable oneness; the indivisible fulfillment of the Universe. All other symbols and geometries reflect various aspects of the profound and consummate perfection of the circle, sphere and other higher dimensional forms of these we might imagine.

Forum Outposts The Geometry Forum Newsletter Winter 1995, page 3 Ask Dr. Math!, continued Look at the sequence 1/(-1/2), 1/(-1/3), 1/(-1/4), and notice again that the denominators -1/2, -1/3, -1/4, ..., are going to zero. Again, we would want the limit of this sequence to be 1/0, but looking at the sequence, it simplifies to -2, -3, -4, ..., and it goes to negative infinity. So which would we assign to 1/0? Negative infinity or positive infinity? Instead of just assigning one of these willy nilly, we say that infinity isn't a number, and that 1/0 is indeterminate. I hope this helps. Ken "Dr." Math Dear Dr. Math: My name is Erica Anderson and I need to know examples of where the Fibonacci sequence is found in nature and how that relates to the Golden Mean. This is for Pre Calculus class. Thanks for your help. Hey Erica, I love this problem. The Fibonacci sequence happens all the time in nature, so much it is amazing. I am having trouble not just sitting here and listing all the occurrences that I can think of, but I will try to resist sending you a seven-page e-mail message. A few examples: Think about a pine cone. Have you ever noticed that the petals spiral up in two directions? Well, the number of petals it takes to get once around is almost always a Fibonacci number.

13. Fibonacci Numbers relating the fibonacci Sequence to the Golden Mean and thereafter to Sacred geometry.In order to initiate this relationship, we divide each of the numbers in http://www.halexandria.org/dward093.htm

Fibonacci Numbers We begin our whirlwind tour of F Lo Sophia and Sacred Geometry by first stopping in Pisa, Italy, where in the year 1202 A.D. (or as currently written, C.E. for “Current Era”), a mathematician and merchant, Leonardo da Pisa wrote a book, Liber Abaci (The Book of Computation). Born in 1179, Leo had traveled during the last years of the 12th century to Algiers with his father, who happened to be acting as consul for Pisan merchants. From the Arabs the young Leonardo Bigollo discovered the Hindu system of numerals from 1 to 9, and from the Egyptians an additive series of profound dimensions. Leo promptly shared his illumination with Europeans by writing his book and offering to the intelligentsia (the small minority who could read) an alternative to the reigning, clumsy system of Roman numerals and Greek letters. Books on mathematics are not normally among the best sellers of any era. Leo’s book, nevertheless, had the effect of convincing Europe to convert its unromantic, Romanized numeral system to the one known today as the Hindu-Arabic numeral system. Leo also introduced to the Western World what has become known as the Fibonacci Series.

Sacred Geometry Tradition holds that over the entrance to Plato’s Academy was written the words: Agewmetrhtoz mhdeiz eisitw Only he who is familiar with geometry shall be admitted here (Apparently a knowledge of the Greek language was also important.) This website is not quite so stringent, and will happily admit any she who is interested in entering. (The guys will, of course, still need some geometry.) Alternatively, anyone who can carry a tune may enter in a bucket or by any other means. Music is, after all, based on geometry and mathematics. For anyone who doesn’t think of themselves as being “familiar with geometry,” the words attributed to Plato’s school might be considering insulting, and thereby construed to have little or no validity. Any grapes from the discourteous must inevitably be sour. This circumstance is indeed unfortunate in that anyone who is not familiar with geometry, anyone who does not appreciate the premise that Philosophy is about understanding the meaning of a mathematical ratio (the Golden Mean ), and anyone who adheres exclusively to a literal interpretation of spiritual teachings...

17. The Golden Rectangle And The Golden Ratio I have since found the construction in geometry, by Harold R. Jacobs. Addendum 4 Each denominator is the product of two consecutive fibonacci numbers. http://www.jimloy.com/geometry/golden.htm

Return to my Mathematics pages Go to my home page The Golden Rectangle and the Golden Ratio click here for the alternative Golden Rectangle and Golden Ratio page This diagram shows a golden rectangle (roughly). I have divided the rectangle into a square and a smaller rectangle. In a golden rectangle, the smaller rectangle is the same shape as the larger rectangle, in other words, their sides are proportional. In further words, the two rectangles are similar. This can be used as the definition of a golden rectangle. The proportions give us: a/b = (a+b)/a This fraction, (a+b)/a, is called the golden ratio (or golden section or golden mean). Above I have defined the golden rectangle, and then said what the golden ratio is, in terms of the rectangle. Alternatively, I could have defined the golden ratio, using the above equation. And then a golden rectangle becomes any rectangle that exhibits this ratio. From our equation, we see that the ratio a/b=1/2+sqr(5)/2 -1/2+sqr(5)/2 or 0.61803398875 . . .) is called the golden ratio. Also, other mathematical quantities are called phi. The golden ratio is also called tau. Some people call the bigger one (1.61803398875 . . .) Phi (an uppercase phi) and the smaller one (0.61803398875 . . .) phi.

Then there is a lowest uninteresting number. That would make that number very interesting. Which is a contradiction. A number of readers have objected that "numbers" in the above theorem should be "natural numbers" (non-negative integers). My reply to one reader was this: Yes, but I wanted to keep it simple and quotable. And the proof that all numbers are interesting should not be boring. From natural numbers, it can be generalized to rationals, as fractions with interesting numerators and denominators are obviously interesting. And what could be more interesting than an irrational that cannot be formed from any finite combination of rationals? I see that David Wells' book
