Ele Willoughby, PhD<p>Happy birthday to <a href="https://spore.social/tags/mathematician" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>mathematician</span></a> Felix Klein (1849-1925). This is a hand-carved and hand-printed image of the famous mathematical object, the Klein bottle, printed in a gradient of pale yellow-green to darker blue-green on paper 8” by 8” (20.3 cm by 20.3 cm). First described by mathematician Felix Klein in 1882, this object has a single surface, rather like a 3D version of a Möbius strip. 🧵<br><a href="https://spore.social/tags/linocut" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>linocut</span></a> <a href="https://spore.social/tags/sciart" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>sciart</span></a> <a href="https://spore.social/tags/printmaking" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>printmaking</span></a> <a href="https://spore.social/tags/mathart" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>mathart</span></a> <a href="https://spore.social/tags/FelixKlein" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>FelixKlein</span></a> <a href="https://spore.social/tags/histstm" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>histstm</span></a> <a href="https://spore.social/tags/mathematics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>mathematics</span></a> <a href="https://spore.social/tags/maths" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>maths</span></a> <a href="https://spore.social/tags/reliefPrint" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>reliefPrint</span></a> <a href="https://spore.social/tags/MastoArt" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>MastoArt</span></a></p>
