Hi Crocus, Fibonacci was an Italian mathematician, who described a sequence of numbers that is often used in art and architecture, as well as in nature. for instance, a nautilus shell's proportions are in a Fibonacci sequence.
you start with 1 (the first number)
Add 1 to that = 2 (the second number)
Then add first number plus second number = 3 (so far, doesn't look like much!)
Then, add second and third number (2+3= 5)
then add third and 4th number 3+5 =8
keep going: 5 + 8 = 13
then 8 + 13 = 21
then 13 + 21 = 34
The intervals between the numbers get bigger and bigger.
I've seen this used in knitting, with 2 colors in stripes that are in a Fibonacci series. I'd be willing to bet if you googled images for Fibonacci you'd find a whole bunch of cool stuff. I'm going to do that right now!
I was a chemistry major in college, back in the dark ages
. I think this popped up in one of my math classes.
