Ele Willoughby, PhDHappy birthday to <a href="https://spore.social/tags/mathematician" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#mathematician</a> David Hilbert (1862-1943)! This <a href="https://spore.social/tags/linocut" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#linocut</a> illustrates the paradox of Hilbert’s Grand Hotel, a thought experiment conceived by Hilbert in 1924 to show the paradox of infinite sets. If you imagine a regular hotel with a finite number of rooms, if they are all filled you can’t add more guests. In an imaginary infinite hotel however, guests are always welcome! 🧵<a href="https://spore.social/tags/sciart" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#sciart</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/histsci" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#histsci</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/printmaking" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#printmaking</a> <a href="https://spore.social/tags/HilbertsGrandHotel" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#HilbertsGrandHotel</a> <a href="https://spore.social/tags/DavidHilbert" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#DavidHilbert</a> <a href="https://spore.social/tags/infinity" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#infinity</a> <a href="https://spore.social/tags/MastoArt" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#MastoArt</a>

Ele Willoughby, PhDThe print shows a grand hotel on a steep angle (with a vanishing point at infinity of course), labelled "Hilbert's Grand Hotel" below a cameo of Hilbert himself, and the slogan "No vancancy. Check in now!" Above the hotel is a glowing infinity symbol. The size of countably infinite sets, like all natural numbers {1,2,3, .... ∞ } is denoted by Aleph Nought ℵ0 shown on the two flags. <a href="https://spore.social/tags/histstm" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#histstm</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/printmaking" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#printmaking</a> <a href="https://spore.social/tags/HilbertsGrandHotel" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#HilbertsGrandHotel</a> <a href="https://spore.social/tags/DavidHilbert" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#DavidHilbert</a> <a href="https://spore.social/tags/infinity" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#infinity</a> <a href="https://spore.social/tags/paradox" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#paradox</a>
