As I pointed out to yet another poster: JFGI. Inserting the words fibonnacci and sequence into a google search will give you a whole plethora of information - far more than anyone here could ever (be bothered to) write down.

In the movie

Max writes the golden ratio as (a/b) = (a/a+b). It should be a/b = (a+b)/a, if, by definition, a>b.

But hey, it may just be a more interesting approach in understanding this stuff than by laborously filtering through the googolplex. Pretty standard approach, heh. You can also get films, music--various symphonies-- set to the golden ratio. Amazing. Oh, the Parthenon too, but hey, that was one of many achievements set by the Greeks. Those Greeks...

There is no evidence to support the assertion that phi, the golden ratio, is important in greek architecture, or anywhere else, for non-mathematical reasons. Indeed, there are many elegant rebuttals of all the abuses of phi that exist. It does occur in nature for very good and well understood reasons (it has the 'slowest' converging rational approximation, in a sense that can be made precise), but none that supports any suggestion that is aesthetically pleasing.Oh, the Parthenon too, but hey, that was one of many achievements set by the Greeks. Those Greeks...

The reason it 'occurs' in the parthenon is becuase some people choose to measure some ratios from some not well chosen positions. There are many rations one can write down from the parthenon that are not phi, but those are all conveniently ignored.

Could you make that more precise? :)It does occur in nature for very good and well understood reasons (it has the 'slowest' converging rational approximation, in a sense that can be made precise)

My wife knitted me a Fibonacci scarf the other day. You can view it http://bp0.blogger.com/_wmbmRX6H5EA/Reul9SH2BkI/AAAAAAAAAMk/Wb3kKqPauTY/s1600-h/2007-03-04-fibonacci-scarf.jpg".

Yes. But you could equally well do a google search and save me the bother.Could you make that more precise? :)

Of what? The difference between Fibonnacci series and power series?please give a simple explanation

Here is the Fibonnacci sequence

1,1,2,3,5,8,13,21,34,55,....

if x(n) is the n'th term it satisfies the rule x(n)=x(n-1)+x(n-2), and x(1)=x(2)=1.

A Taylor seres looks like this:

sin(x)=x-x^3/3! +x^5/5! - .....

I don't see that there is anything that needs to be said to explain that they are different.
