Huge thanks to Destin for the chat and footage. Check out their video!

I was at the 2 July 2019 total solar eclipse in Argentina: 30°41'07.6"S 68°28'50.2"W

My old video "Solar Eclipse Maths and the Cosmic Coincidence of the Saros Cycle"

We've made some Think Maths teaching resources on approximating pi with a continued fraction.

The wikipedia page on solar eclipse cycles is actually pretty good.

Wolfram Alpha can sort you out for all your continued fraction needs.

And this is the page with more about continued fractions than you'll ever want to know.

CORRECTIONS

- I misspoke a couple of times (303 instead of 333, 2023 instead of 2022) but the correct number was always onscreen. That's what I get for doing it all in one take!

- Yes, I mooned the camera. I'm just that on theme.

- Let me know if you spot anything else!
