Regdar and the Fighters<p>I'm late, but my <a href="https://musician.social/tags/piday" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>piday</span></a> hot take is that pi actually has only about 70 digits.</p><p>That's the maximum number of significant digits you can have when doing geometry to planck length precision at size of the universe scale.</p><p>Any attempt to include more digits is just intentionally introducing inaccuracy to your results</p>

The FreeDOS Project<p>If you're curious about last week's <a href="https://fosstodon.org/tags/PiDay" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>PiDay</span></a> article that used a FreeDOS program to "measure" π by counting pixels, here's a follow-up. </p><p>It's about how to write an academic journal article in groff— but really, it was an excuse to explain why the method gives π=2.828 🤓</p><p><a href="https://technicallywewrite.com/2025/03/18/academic" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">technicallywewrite.com/2025/03</span><span class="invisible">/18/academic</span></a></p><p>Short version: it measures a square inside the circle, so the best you can get is 8cos(π/4) or π=2✓2</p><p>*Could be explained better, but the diagrams look really nice! 🤣</p>

Kevin Severud :donor:<p>“[Pi Day] was founded [in 1988] by physicist Larry Shaw, who at the time was on staff at the Exploratorium, a science museum in San Francisco. It began at an Exploratorium staff retreat in Monterey, California, which Shaw and his colleagues took to mark three years since the death of the museum's founder, Frank Oppenheimer, the brother of famed Manhattan Project leader J.
