Didn’t we already know the value of pi? At least the first one hundred trillion digits or so. Yes, but this is an interesting story about the relation between maths and physics. Let’s have a look. Paper: https://journals.aps.org/prl/abstract... This video comes with a quiz which you can take here: https://quizwithit.com/start_thequiz/... Clarification to what I said at 4:20 -- There are many ways to calculate pi and indeed many converge much faster than that sum. I didn't mean to raise the impression that this is the only way we know to calculate pi! 🤓 Check out my new quiz app ➜ http://quizwithit.com/ 💌 Support me on Donorbox ➜ https://donorbox.org/swtg 📝 Transcripts and written news on Substack ➜ https://sciencewtg.substack.com/ 👉 Transcript with links to references on Patreon ➜   / sabine   📩 Free weekly science newsletter ➜ https://sabinehossenfelder.com/newsle... 👂 Audio only podcast ➜ https://open.spotify.com/show/0MkNfXl... 🔗 Join this channel to get access to perks ➜    / @sabinehossenfelder   🖼️ On instagram ➜ https://www.instagram.com/sciencewtg/... #science #sciencenews #physics #maths
