'TOUCH' - Math: The Series


I don't watch too much tv, so I think, but I must say: I am really looking forward to watching this show!!  I get so excited by numbers, patterns, codes, etc.  I think about how much other generations were able to accomplish because they had/made time to figure things out.  If we can take 1% of the population and raise them to be curious, I believe so many amazing things could be deciphered.  Anyway, check out the clip.  Kiefer Sutherland also did the series 24. This one is about the Fibanacci code.

How it relates to nature, according to wikipedia today: http://en.wikipedia.org/wiki/Fibonacci_number
--------------------------------------------------------------------------------------------
In nature

Fibonacci sequences appear in biological settings,[6] in two consecutive Fibonacci numbers, such as branching in trees, arrangement of leaves on a stem, the fruitlets of a pineapple,[7] the flowering of artichoke, an uncurling fern and the arrangement of a pine cone.[8] In addition, numerous poorly substantiated claims of Fibonacci numbers or golden sections in nature are found in popular sources, e.g., relating to the breeding of rabbits, the seeds on a sunflower, the spirals of shells, and the curve of waves.[49] The Fibonacci numbers are also found in the family tree of honeybees.[50]
Przemysław Prusinkiewicz advanced the idea that real instances can in part be understood as the expression of certain algebraic constraints on free groups, specifically as certain Lindenmayer grammars.[51]
Illustration of Vogel's model for n=1 ... 500
A model for the pattern of florets in the head of a sunflower was proposed by H. Vogel in 1979.[52] This has the form
\theta = \frac{2\pi}{\phi^2} n,\  r = c \sqrt{n}
where n is the index number of the floret and c is a constant scaling factor; the florets thus lie on Fermat's spiral. The divergence angle, approximately 137.51°, is the golden angle, dividing the circle in the golden ratio. Because this ratio is irrational, no floret has a neighbor at exactly the same angle from the center, so the florets pack efficiently. Because the rational approximations to the golden ratio are of the form F(j):F(j + 1), the nearest neighbors of floret number n are those at n ± F(j) for some index j which depends on r, the distance from the center. It is often said that sunflowers and similar arrangements have 55 spirals in one direction and 89 in the other (or some other pair of adjacent Fibonacci numbers), but this is true only of one range of radii, typically the outermost and thus most conspicuous.[53]

[edit] The bee ancestry code

Fibonacci numbers also appear in the description of the reproduction of a population of idealized honeybees, according to the following rules:
  • If an egg is laid by an unmated female, it hatches a male or drone bee.
  • If, however, an egg was fertilized by a male, it hatches a female.
Thus, a male bee will always have one parent, and a female bee will have two.
If one traces the ancestry of any male bee (1 bee), he has 1 parent (1 bee), 2 grandparents, 3 great-grandparents, 5 great-great-grandparents, and so on. This sequence of numbers of parents is the Fibonacci sequence. The number of ancestors at each level, Fn, is the number of female ancestors, which is Fn−1, plus the number of male ancestors, which is Fn−2.[54] (This is under the unrealistic assumption that the ancestors at each level are otherwise unrelated.)

Loving it!  I don't assume that my children will love math, patterns, numbers, and solving problems to the same degree as me, but I think it would be neat if they grow to appreciate its beauty in the universe. :-)
