He used it to describe rabbit populations, but the sequence is commonly observed in nature,<a href="https://spore.social/tags/linocut" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#linocut</a> <a href="https://spore.social/tags/printmaking" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#printmaking</a> <a href="https://spore.social/tags/mathematics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#mathematics</a> <a href="https://spore.social/tags/mathart" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#mathart</a> <a href="https://spore.social/tags/sciart" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#sciart</a> <a href="https://spore.social/tags/GoldenRatio" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#GoldenRatio</a> <a href="https://spore.social/tags/GoldenRectangle" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#GoldenRectangle</a> <a href="https://spore.social/tags/GoldenSpiral" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#GoldenSpiral</a> <a href="https://spore.social/tags/Fibonacci" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Fibonacci</a> <a href="https://spore.social/tags/FibonacciSequence" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#FibonacciSequence</a> <a href="https://spore.social/tags/fibonacciday2024" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#fibonacciday2024</a> <a href="https://spore.social/tags/FibonacciDay" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#FibonacciDay</a>

Ele Willoughby, PhDFor the <a href="https://spore.social/tags/Spacetober" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Spacetober</a> prompt lift-off: it’s my portrait of <a href="https://spore.social/tags/mathematician" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#mathematician</a> and NASA scientist Katherine Johnson (née Coleman; 1918-2020). One of the first Black women employed as a NASA scientist (and its predecessor NACA), she was known for her mastery of complex manual calculations of orbital mechanics and played a pivotal role in the success of the US crewed spaceflights from the beginning. 🧵1/n<a href="https://spore.social/tags/mathematics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#mathematics</a> <a href="https://spore.social/tags/sciart" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#sciart</a> <a href="https://spore.social/tags/linocut" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#linocut</a> <a href="https://spore.social/tags/printmaking" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#printmaking</a> <a href="https://spore.social/tags/womenInSTEM" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#womenInSTEM</a> <a href="https://spore.social/tags/spaceArt" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#spaceArt</a> <a href="https://spore.social/tags/histsci" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#histsci</a> <a href="https://spore.social/tags/BlackInSTEM" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#BlackInSTEM</a> <a href="https://spore.social/tags/MastoArt" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#MastoArt</a>

Ele Willoughby, PhDHappy birthday to <a href="https://spore.social/tags/mathematician" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#mathematician</a> & geodesist Gladys West (née Brown in 1930)! Shown with satellite tracks & 3 satellites important to her career: Seasat, GEOS-3 & a GPS satellite. Her work, using math to precisely model the shape of Earth, laid the groundwork for GPS! Born to sharecropper parents in Virginia, she graduated with a Math BSc in ‘52 then MSc at VSU in ‘55. 🧵1/n <a href="https://spore.social/tags/linocut" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#linocut</a> <a href="https://spore.social/tags/printmaking" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#printmaking</a> <a href="https://spore.social/tags/womenInSTEM" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#womenInSTEM</a> <a href="https://spore.social/tags/BlackInSTEM" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#BlackInSTEM</a> <a href="https://spore.social/tags/histsci" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#histsci</a> <a href="https://spore.social/tags/Spacetober" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Spacetober</a> <a href="https://spore.social/tags/EarthScience" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#EarthScience</a> <a href="https://spore.social/tags/Math" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Math</a>
