David Cantrell 🏏<p>Proof of the non-existence of <a href="https://fosstodon.org/tags/magic" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>magic</span></a>: consider a magic bag which can only contain bags like itself. The bag can not contain nothing, therefore it contains infinite bags. Given that everyone implementing anything <a href="https://fosstodon.org/tags/recursive" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>recursive</span></a> fucks up like this at least once, any wizard doing this will crash the universe. The universe has not crashed. Therefore magic doesn't exist. <a href="https://fosstodon.org/tags/ProofByContradiction" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>ProofByContradiction</span></a></p>

David Cantrell 🏏<p>At about 2 am I came up with an elegant <a href="https://fosstodon.org/tags/ProofByContradiction" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>ProofByContradiction</span></a>. But now I can’t remember what it was I proved. Bother. <a href="https://fosstodon.org/tags/mathstodon" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>mathstodon</span></a></p>
