Thanks to Laura Taalman for 3D printing the fantastic shapes for me. She's a Professor of Mathematics at James Madison University. https://mathgrrl.com/

Thanks to Roger Antonsen, for testing the local maxima of the Grace shape for this video. Roger sadly passed away earlier this year. His department at the University of Oslo have published a memorial page to celebrate him: https://www.mn.uio.no/ifi/personer/minneside.html

Much appreciation to Donald's children who talked to me about late nights spent with their father watching a computer crunch away at some math.

CORRECTIONS - 00:23 I say "August 22" which is wrong: this Tuesday is August 20. Please don't tell my publishers I got that wrong. - At 16:50 I say "eight times" which is completely wrong and not part of the formula. No idea what was going on there. The onscreen value (and everything else I say) is correct. - Let me know if you spot anything else!

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: https://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: https://www.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?

CONJECTURE DISCLAIMER: We believe that the "there must exist a single-angle polyhedron for any angle θ with an algebraic sine" conjecture is true but don't have a nice proof. There seem to be all the required parts for the proof in papers by Sydler and Jessen, but it's not fully assembled.

I think this is the original claim that it was the mid-point of his life. From April 2019. https://www.mjjcommunity.com/threads/unusual-michael-jackson-coincidence-how.142918/

Here is the quote about the time of day his hair caught fire: "at the Shrine Auditorium Friday night" https://www.upi.com/Archives/1984/01/28/Michael-Jackson-hospitalized-after-fireworks-mishap-on-set-of-Pepsi-commercial/9136444114000/

Here is the regulation governing daylight saving time in Indiana when Michael Jackson was born: 1957: "The General Assembly votes to make Central time the official time of the state but permit any community to switch to daylight-saving time during the summer." https://eu.indystar.com/story/news/politics/2018/11/27/indianapolis-indiana-time-zone-history-central-eastern-daylight-savings-time/2126300002/

This website claims Gar did switch to daylight saving in 1958, specifically: "27 Apr 1958 - Time Zone Change (CST → EST)" but I'm not sure where that information has come from. https://www.timeanddate.com/time/change/usa/indianapolis?year=1958

Happy Pi Day: 14 March 2023. (Yes, the video goes out a few days early. So teachers have time to plan their Pi Day activities.)

Huge thanks to Eric and the whole team for letting us in to skid some cars and calculate pi.

Get your North by North-North tour merch here! https://standupmaths.teemill.com/collection/north-north-north/

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.

YES, the improvement should be 40,832,277,770%, not what I say in the video. The "408,322,778" multiple was correct and I did the percentage the wrong way. There will not be a follow-up video to correct that.

The improvement was to my code from this video: https://www.youtube.com/watch?v=_-AfhLQfb6w

This is episode 038 of the A Problem Squared podcast which started it all: https://aproblemsquared.libsyn.com/038-fldxt-in-wordle-and-improv-tact-hurdle

Here is Benjamin Paaßen's full grid of all results and techniques used. It also has links to all the code as well. https://docs.google.com/spreadsheets/d/11sUBkPSEhbGx2K8ah6WbGV62P8ii5l5vVeMpkzk17PI/edit#gid=0

The article by "encody" I mentioned: https://medium.com/geeklaunch/how-to-speed-up-your-code-224-444-739-using-graphs-cc37dc395c0c

This is the reverse-frequency alphabet. Which is frequency in words, not in use (which would allow for frequency of word use; this list counts each word once). QXJZVFWBKGPMHDCYTLNUROISEA

And whynot, a whole bunch of code. All of it is better than mine. All of it. (Even if you ran it all sequentially.)

CORRECTIONS - 10:49 Yes, I said "converges" by accident when filming and I dropped in a "diverges" in the edit. I don't think anyone will notice. - I think my big divergent observation may not hold! Clarence Lam was the first to spot that the lead n out the front of the series can explain the increasing times without the series itself needing to diverge. I suspect there is still an argument to be made around the rate at which times go up outpacing n, but I’m not sure it’ll be super intuitive. -Let me know if you spot any other mistakes!

This site was super helpful at explaining the history and math of apportionment. As always though, verify the specifics of the data yourself (but all the general points are definitely correct). https://www.maa.org/press/periodicals/convergence/apportioning-representatives-in-the-united-states-congress-introduction

George Washington was voiced by my friend Ben Moor. They are in The Queen's Gambit!

The Voice of Alabama is voiced by The Voice of Alabama. They are in Alabama!

Thanks to all of my Patreon supporters who mean I can spend a silly amount of time on a video like this. So much time. So much historical data. You too can help support me: https://www.patreon.com/standupmaths

CORRECTIONS - I didn't bother showing me locking cell references in the animations. Things like "=B4/B2" should have been "=B4/$B$2" so I could drag the formula down. We took that out in the interest of clarity. - Yes, at 13:20 I say "the divisor ceases to lose some of its strict meaning" which is the opposite of what I meant! the sentence needs but the one negative. Either of these would work: "the divisor loses some of its strict meaning" OR "the divisor ceases to have some of its strict meaning". - Sorry, at 16:47 column D is wrong. These are different numbers using 880 but the values over in E use the correct 930. It's just a display issue and does not change the results (despite being a bit confusing!). Spotted by a few people including Thomas Klemm and AverageJon. - Let me know if you spot anything else.

And as you may have noticed, the laser video with Seb is not out yet. I think it's going to trail this one by quite a while.

Thanks to all of my Patreon supporters funded this video. Normally I would just visit a maths museum and have a fun day out. But thanks to you all, I was able to hire a camera person to follow me around. Plus I did a day of prep-work writing code before my visit and a day of generating plots after the visit. That's thanks to Patreon. (Who am I kidding; I would have done the coding and plots anyway.) https://www.patreon.com/standupmaths

CORRECTIONS - At 14:13 I say the mass "of the submersible" when I should be talking about the mass of water above the submersible. -At 31:34 I say "grams" instead of "kilograms". Which takes some of the air out of my unit bashing. - Let me know if you spot any other mistakes!
