If you extend the numerical digits with letters, just like you would in hexadecimal but further up to A-Z in base 36, and you limit the ages to under 1000, and the gap to under a 100, then for bases 26 to 36 you get eleven palindrome ages with gaps of length base-1 and digit representation "POOP".
E.g. in base 26: age1 = 674 = PO(26) and age2 = 649 = OP(26), age gap = 674 - 649 = 25.

On avance dans l'implémentation du générateur de patterns inspiré des "cavaliers noirs et rouges" de la vidéo de Numberphile (https://www.youtube.com/watch?v=UiX4CFIiegM).
Aujourd'hui: on met en place la possibilité d'avoir plusieurs joueurs/couleurs, et on vérifie qu'on arrive bien à reproduire l'exemple de la vidéo. Cela devrait nous permettre de commencer après à généraliser et à jouer à faire des nouvelles visualisations!

Deuxième étape dans mon implémentation du générateur de patterns de la vidéo de #numberphile: où l'on arrive à reproduire la séquence "de base", avec un code plus ou moins propre, mais un résultat encore franchement moche il faut bien le dire!

Numberphile - “Red & Black Knights (extraordinary result)”
Kinda like the discoveries of fractals, but it's all integers.

La dernière vidéo de Numberphile avec le Prof. Neil Sloane m'a donné envie de faire ma propre version du générateur de "patterns". Outre la curiosité mathématique, je pense que code ça peut amener à des questions intéressantes de programmation. Essayons, on verra où ça nous mène !

#Numberphile videos with Neil Sloane are always fun but this one especially so because it has relatively easy to make visualisations that are still very surprising and largely unexplored. "Deterministic chaos" AKA we don't know yet how to model & predict these results.

@metgitarenenzo @ionica al fan van haar sinds de eerste keer dat ze bij #numberphile een uitzending had. Zeker 10 jaar geleden dus. Ze kan zo goed uitleggen. Fijne stem ook.
Oh, na even zoeken: 11 jaar geleden zelfs. Gekkenhuis (:

loving this #Numberphile video that dropped today. love these sorts of unimaginable numbers/sizes/etc. https://youtu.be/sJqceEImtew?si=cfQvGLFVdTEBlBm3

There's a new #Numberphile video out with Ben Sparks. At the end they showed a teaser of another video with Ben, "Beautiful Trigonometry". Back when that came out, I recreated Ben's visualisation with settings and sliders in Processing's p5js. Try it! https://ednl.github.io/spirojs/
Video alt: a colourful circle composed of miniature circles (balls) seems to spin around inside a bigger circle. It's an illusion: all the individual balls move in perfectly straight lines on diagonals of the big circle.

“A New Way to Look at Möbius Strips”
Nothing new in terms of results, even the ones that I knew as a kid, but a nice visualization that clarifies why things work out the way that they do.

This was the sort of stuff I loved in upper-level undergraduate mathematics.

Just heard a snippet of #numberphile on swedish radio 🙂
The show "språket" has an episode all about numbers 👍 If you know swedish and like numbers you should toitally give it a listen.

It's me! On #numberphile! Talking about my favourite polyhedron!
https://youtu.be/3X2aQIMx5bs?feature=shared
After many years never being able to line up doing numberphile video, I was really glad that Brady and I ended up in the same place to do this. I love the animations and especially the sound effects!

I really like #numberphile so it's doubly disappointing to see them giving so much space (and legitimacy!) to effin' chatGPT in their latest videos :/

fractals in reality from Hideki Tsuiki via #numberphile
that h-fractal absolutely has my heart. i want to see it 10 times the size. it's like some weird reality where mathematics is projected into the real world.

“A 1.58-Dimensional Object”

Even better when it gets to the “integer dimensioned" fractals.

I learned via #Numberphile about Sloane's Gap, an empty band that appears when you plot counts of integers appearing in the Online Encyclopedia of Integer Sequences (OEIS.org). Here's the 2011 original plot and my updated version with 2024 data and coloring some categories.

I had to watch the latest episode of #numberphile through my fingers: food in the library! Arghh 😱
The lazy caterer's sequence:
https://www.youtube.com/watch?v=Xd9UZSodeN8 -
Hey, #maths types. New #numberphile video about "the lazy caterer's sequence", maximising the number of pieces you can cut a pizza into with straight-line cuts by ensuring that each cut intersects all previous cuts, so that after n cuts you've got 1+Σn pieces. But doing it the obvious way tends to give lots of tiny little triangular bits. Has anyone looked into how to keep the slices as close to equal as possible? I can't find anything. Is it not even remotely possible?
