Thanks to Phil Chapman for sending in the question and taking the time to record themselves reading it for me.

Geoscience Australia were super helpful and answered all of my ridiculous questions.

Check out Steve Mould’s Numberphile video on fractal coast lines.

Thanks to Bec Hill: comedian; podcast host; and the new voice of Geoscience Australia.

– At 14:02 I accidentally say a 9 instead of a 7 (the area is 247719 not 249719). The on-screen numbers are correct. Phew.
– Let me know if you spot any other mistakes.

Thanks to my Patreons who mean I can spend tens of days of my life on a silly video like this. Here is a random subset of those fine Patreon People:

Andy B
Nicholas Koceja
Jordan Scales
Malcolm Rowe
Derek Chandler
Paul LeVan

Patrick Stover

As always: thanks to Jane Street who support my channel. They’re amazing.
