Hugh thanks to the British Museum for getting the papyrus out of storage for me to see. You can watch the other non-papyrus video I made with them over here: youtu.be/WctTJVdsISE
If you want to have a closer look at the maths on the papyrus, there are scans on the British Museum site: britishmuseum.org/collection/object/Y_EA10058
CAN YOU SOLVE IT:
You have to divide 100 loaves between 5 men in such a way that the shares received shall be in arithmetical progression. And that 1/7 of the sum of the largest 3 shares shall be equal to the sum of the smallest 2. What is the difference of the shares?
Huge thanks to my Patreon supporters. They keep my bread fairly divided. patreon.com/standupmaths

![Eclipses can be approximated the same way as π. [ONE TAKE!]
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°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.

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!

CORRECTIONS
- Thanks to a few people for pointing out my dry-wipe pseudo-code for Bubble Sort is a bit out. where it says if i [greater than] i+1 it should read if L[I] [greater than] L[i+1]”. Also this correction should use the greater than symbol but YouTube wont let me put them in.
