Happy #FibonacciDay

Nov 23 or 11.23 is #FibonacciSequenceDay.

Several years ago I saw a group of #Dunlin in a nearly perfect #FibonacciSequence. They were missing the first single bird, but 1 - 2 - 3 - 5 - 8 - 13 proves that #FibonacciNumbers are found everywhere in nature ;)

ok enough doom-reskeeting, it’s cat time

Stunning observation by @mathwomen.bsky.social‬, two opposing spiral galaxies, more examples of #Fibonaccinumbers n (1,1,2,3,5,8,13,21,34...)by me
n/(n+1)+1=(n+1)/n
n+n+1=(n+1)²/n
2n²+n=n²+2n+1
n²-n-1=0
leads to f(x)=x²-x-1
=(x-0.5)²-5/4
x1,2=(1+/-5⁰·⁵)/2

It was #mathisfun counting #FibonacciNumbers, comparing sizes, & reading about shapes - which belong/which don’t (&importantly, why) at @ncbg.bsky.social on a beautiful spring day with a lovely 3 1/2 year-old. I gave her #organic Bahri dates & Pixie #tangerine after! #mtbos #iteachmath

I'm looking forward to sharing about Fibonacci / Pingala Numbers mathinst.com/pingala in the Chapel Hill #mathCircle for 1st-3rd graders. #mtbos #iteachmath #mathisfun #fibonacciNumbers #pingalaNumbers

Hi fam,
have fulfilling day!
My contribution:
#ALText
A blue #singleline with the slope 6765/4181. The slope is less than 2, more than 3:2, less than 5:3, more than 8:5. Numerator and denominator are #Fibonacci #numbers

A little (tested) progress today. Got my own explicit expressions for #PellNumbers and #FibonacciNumbers that I can use in this alternative approximation for #MarkovNumbers, but still need to justify the approximation / calculate its range of error. #Unicity
