Thanks to Bec Hill for voicing the Norths Tour. I have a podcast with Bec and we talked about me making this video in the latest episode: https://aproblemsquared.libsyn.com/49-grand-theft-auto-five-and-girlfriend-digit-size

If you're anywhere near Worth Matravers in Dorset you should absolutely visit The Square and Compass. https://www.squareandcompasspub.co.uk/

Here is the OS Maps post about the triple alignment. https://www.ordnancesurvey.co.uk/newsroom/news/three-norths-align-great-britain

However, if you watch their video be warned about when the diagonal line crosses the 2° line: their line slopes to the left and moves to the right, whereas my line slopes to the right and moves to the left. This is because the OS is drawing the zero-point for magnetic-vs-grid but I'm doing magnetic-vs-true. Which is a mirror image.

You can see all of NOAA's Historical Magnetic Declination data here: https://www.ncei.noaa.gov/maps/historical_declination/

Huge thanks to my Patreon supporters who funded this ridiculous trip to the south coast of the UK to film a silly video. They also bought me two pints of beer and one packet of crisps. Which were all totally key props/research and not a mis-use of Patreon support funds. Support me and maybe next time I'll get a second packet of crisps. https://www.patreon.com/standupmaths

Bonus thanks to Christopher James who put a link to the OS article about this in a maths communication whatsapp group with the message "I hope someone is planning to visit and make an interesting video about this." And thanks to Colin Beveridge who answered some key questions about it in that group.
