Kyle Rankin<p>In honor of Pi day here is a video of my vintage Marchant electromechanical calculator approximating Pi using a common approach (355 / 113).</p><p>This type of calculator was popular among physicists working on the Manhattan project, and yes, if you divide by zero it goes into an infinite loop.</p><p><a href="https://mastodon.kylerank.in/tags/piday2024" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>piday2024</span></a></p>

AkaSci 🛰️<p>The remarkable equation for π by Indian mathematician Srinivasa Ramanujan (1887 - 1920) is an infinite series with some puzzling numbers. The first k terms of the sum generate π whose first ~8*k decimal digits are accurate. These digits do not change with additional terms 🤔</p><p>E.g., the 1st term gives π = 3.141592 73001..., which is accurate to 6 decimal places.</p><p>Using 2 terms, we get π = 3.141592 653589793 87808..., which is accurate to 15 decimal places.</p><p><a href="https://fosstodon.org/tags/PiDay2024" class="mention hashtag" rel="tag">#<span>PiDay2024</span></a> <a href="https://fosstodon.org/tags/PiDay" class="mention hashtag" rel="tag">#<span>PiDay</span></a><br />2/n</p>
