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 ;)

A brand new fiddlehead fern frond is beginning to unfurl. It was photographed from bottom to top. To make out details like the rust-brown hairs on the backs of the spirals and a tiny greenish-yellow insect (lacefly?), I had to overexpose the background: a white sky with light green, fresh leaves.

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
#sharingisthenewlearning #GoldenRatio
The graph of the quadratic function f(x)=x²-x-1, a parabola that intersects the y-axis at -1, was drawn with this ingenious tool/toy: https://www.matheretter.de/rechner/gfplot One of its roots, x2 in the picture, is the Golden Ratio 1.6180339... Two sets of opposing yellow spirals inside a large daisy with narrow white petals The number of spirals is each a Fibonacci number! Flower with eight (a Fibonacci number) bright purple petals, whose colour deepens towards the center and yellow stamens The background is green and gray. Poppy flower whose seed capsule has 13 (a Fibonacci number) rays. Only the interior is sharp, the red petals and the background look like a non-photorealistic painting.

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

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
#GoldenRatio #Phi #MathArtMarch #mathematics #sharingisthenewlearning #recursive
source: https://www.matheretter.de/rechner/gfplot, an ingenious toy/tool that I used to draw a blue line with a slope of about phi, the Golden ratio. and a pink parabola that has two intersections (=zeros/roots) with the x-axis. One of them equals phi exactly; See more in the alternative text that belongs to the photo to the right, please! Blue parabola that shows the the function f(x)=x²-x-1 Its zeros or roots are x1 about -0.61803399 and x2 about 1.61803399 with x2 happens to be phi, the Golden ratio, made of Fibonaccinumbers: 1:1=1, 2:1=2, 3:2=1.5, 5:3=1.666..., 8:5=1.625, ...6765/4181 is about 1.61803396!

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
