I let the rest of it flow over me and it was still <a href="https://sfba.social/tags/fascinating" class="mention hashtag" rel="tag">#<span>fascinating</span></a>, but if you ask me tomorrow what it said I might not remember.</p><p><a href="https://sfba.social/tags/geek" class="mention hashtag" rel="tag">#<span>geek</span></a> <a href="https://sfba.social/tags/math" class="mention hashtag" rel="tag">#<span>math</span></a> <a href="https://sfba.social/tags/mathematics" class="mention hashtag" rel="tag">#<span>mathematics</span></a> <a href="https://sfba.social/tags/pureMathematics" class="mention hashtag" rel="tag">#<span>pureMathematics</span></a> <a href="https://sfba.social/tags/pureFun" class="mention hashtag" rel="tag">#<span>pureFun</span></a> <a href="https://sfba.social/tags/fun" class="mention hashtag" rel="tag">#<span>fun</span></a> <br /><a href="https://youtu.be/Xv8FBjo1Y8I?si=ZXkltt_L0FNfQZBj" target="_blank" rel="nofollow noopener noreferrer" translate="no"><span class="invisible">https://</span><span class="ellipsis">youtu.be/Xv8FBjo1Y8I?si=ZXkltt</span><span class="invisible">_L0FNfQZBj</span></a></p>
