Dodecaplex is based on the mathematics of Saul Schleimer and Henry Segerman.

You can read more about the maths behind Dodecaplex, and the wider family of Quintessence puzzles, in their paper “Puzzling the 120-cell”. arxiv.org/abs/1310.3549

As well as this puzzle, Henry has other amazing stuff on his Shapeways page.

Watch my previous videos with Henry. All filmed during one mathematical journey to Edinburgh at the glorious Summerhall. The “Brilliant Geometry” one looks more at how 4D shapes are printed in 3D.

$Eclipses can be approximated the same way as π. [ONE TAKE!] Huge thanks to Destin for the chat and footage. Check out their video! https://www.youtube.com/watch?v=Nk0MRxXqo9s I was at the 2 July 2019 total solar eclipse in Argentina: 30°4107.6S 68°2850.2W My old video Solar Eclipse Maths and the Cosmic Coincidence of the Saros Cycle https://www.youtube.com/watch?v=ieUvzy6rnnw Weve made some Think Maths teaching resources on approximating pi with a continued fraction. http://think-maths.co.uk/standupmaths-videos?yt-pi-approx#pi-approx The wikipedia page on solar eclipse cycles is actually pretty good. https://en.wikipedia.org/wiki/Eclipse_cycle Wolfram Alpha can sort you out for all your continued fraction needs. https://www.wolframalpha.com/input/?i=continued+fraction+%5B3;+7,+15,+1%5D And this is the page with more about continued fractions than youll ever want to know. http://www.maths.surrey.ac.uk/hosted-sites/R.Knott/Fibonacci/cfINTRO.html CORRECTIONS - I misspoke a couple of times (303 instead of 333, 2023 instead of 2022) but the correct number was always onscreen. Thats what I get for doing it all in one take! - Yes, I mooned the camera. Im just that on theme. - Let me know if you spot anything else!
