Benjamin Cornish @mathematicians-pod.bsky.social · 13/10/2026Apparently every pair of #dobble cards have a matching image, but honestly I just can't see it. 010
Benjamin Cornish @mathematicians-pod.bsky.social · 23/09/2026Trying to get the alternator out is like the sofa moving problem on very hard mode. 020
Benjamin Cornish @mathematicians-pod.bsky.social · 24/08/2026Hey folks, I've started a #daily #logicpuzzle. I call it #numstep. Draw a self avoiding walk through my grids, if you can. bsky.app/profile/nums... 000
Benjamin Cornish @mathematicians-pod.bsky.social · 15/08/2026I saw some great #maths in action today by Andy (Mr Magic) at the #canfordschool summer fete. Tell me you don't want to try this at home... 000
Benjamin Cornish @mathematicians-pod.bsky.social · 12/08/2026I just showed my wife my pinhole camera. She said "all I can see is a prick". So, not happy about that. #eclipse 031
Benjamin Cornish @mathematicians-pod.bsky.social · 29/07/2026The London #sciencemuseum have a great collection of maths history. I saw: A liquid computer for economic differential equations; an old trig circular slide rule; and the analogue computer for tide predictions. Good times all round, strongly recommend. #mathshistory #mathsinmuseums 122
Benjamin Cornish @mathematicians-pod.bsky.social · 29/07/2026I'm having a great time playing with aperiodic tesselation in the pattern pod at the London #Sciencemuseum. Well done to the designers 010

Benjamin Cornish @mathematicians-pod.bsky.social · 26/07/2026A train leaves the station (bottom) heading west. Can it return to the station heading east? Is there anywhere the train might get stuck? Is there anywhere the train can reach but only from one direction? I call this directed node networks. #mathsky #graphtheory #math4kids 030
Benjamin Cornish @mathematicians-pod.bsky.social · 24/07/2026Here are the ways to draw 4 lines with distinct intersection arrangements. Can you give me an interesting question that is prompted by this image? #mathsky #holidaymaths 251
Benjamin Cornish @mathematicians-pod.bsky.social · 26/06/2026Here's a fun question... By the way I need an answer real fast 010
Benjamin Cornish @mathematicians-pod.bsky.social · 26/06/2026I just claimed my #tiletoday. A small bridge in my village, forever a digital link to maths history. Claim yours today at www.tile.today , it's free and fun. Just walk somewhere, and claim it for yourself. Like Pokémon go but without the teddies. 000
Benjamin Cornish @mathematicians-pod.bsky.social · 07/05/2026"A fair 8-sided dice has faces labelled K,A,N,G,A,R,O,O. The dice is rolled repeatedly..." Just another normal day as a mathematician. #AlevelMaths 020
Benjamin Cornish @mathematicians-pod.bsky.social · 23/04/2026I've been struggling to make a joke about how "a man with a hammer sees only nails." Except I have a rusted wheel bearing that I need to hammer "out", whilst a happer typically pushes "in". I was delighted to discover a "slide hammer" Is a real tool. And now I own one. P.s. got the bugger 010
Benjamin Cornish @mathematicians-pod.bsky.social · 22/04/2026I just glanced over my analytics page for #themathematicianspod. I am delighted that I have reached so many countries. *Scrolls down to near the bottom of the list* Oh cool, a single download from #Palestine... Wait, "Disputed" ‽ Could we not just say Palestine? (Or OPT, as the UN does) 000
Benjamin Cornish @mathematicians-pod.bsky.social · 13/04/2026Who can tell me what this #wildcurve is? A stable fluid boundary on an angled chopping board with a laminar water jet. #mathsky #mathsinthewild 196
Benjamin Cornish @mathematicians-pod.bsky.social · 12/04/2026Tonight you can draw a straight line between Jupiter and Venus... I mean what are the odds of that! #AstrologyTruth P.s. go outside and look up, it's really good for your health to remember how small we are. 000
Benjamin Cornish @mathematicians-pod.bsky.social · 11/03/2026My first attempt at a #DiscreteDynamicalSystem Take a number, n If (n-1) is prime then map n -> n^2 If (n-1) is composite then map n-> Aliquot sum of (n-1) Numbers 1-19 all end in a cycle. I am not sure about 20. eg. 6 -> 36 -> 13 -> 16 -> 9 -> 7 -> 6. #mathsky #recreationalmaths #mathsart 011
Benjamin Cornish @mathematicians-pod.bsky.social · 10/03/2026Competition time: What are the "Rules", and what happens to 20? (Spoiler - my PC has counted 31 steps from 20 and hit a number too big to process, no cycle in sight) 000
Benjamin Cornish @mathematicians-pod.bsky.social · 28/01/2026My latest obsession with maths teacher bingo has now grown to a 5*6 grid... I might have to stop here. #alevelmaths 1100
Benjamin Cornish @mathematicians-pod.bsky.social · 23/01/2026Who wants to play: "Guess what I've been teaching" #alevelmaths 110
Benjamin Cornish @mathematicians-pod.bsky.social · 22/01/2026I've started a "Maths lesson Bingo" with my students. Can anyone suggest some phrases for my next card to be 4*4? #alevelmaths 792
Benjamin Cornish @mathematicians-pod.bsky.social · 21/01/2026Follow up from my #alevelmaths student: If you use 2D vectors for a high order polynomial, the resulting plot is, once again, 2D - however it is highly disorganised: Here we see a Quintic Equation. #mathsky 010
Benjamin Cornish @mathematicians-pod.bsky.social · 21/01/2026A great observation from my #Alevelmaths student: If you create a polynomial with vector coefficients $r=a+bt+ct^2+dt^3...$ you can get higher dimensional equivalents of the polynomial. Here is a 3D quartic equation. #mathsky 000
Benjamin Cornish @mathematicians-pod.bsky.social · 10/01/2026Very happy with this two cord braid this morning 010

Benjamin Cornish @mathematicians-pod.bsky.social · 16/12/2025Which is better, artistically, to see the layers of fractal pentomino tiles, or just a sea of mini pentominoes? #pentomino #mathart #mathsky #tessellation 110
Benjamin Cornish @mathematicians-pod.bsky.social · 16/12/2025Here is an improved mosaic of pentominoes, this time without using a 'tile stamp' method and instead a more organic fill. It contains... F| 565 I| 952 L| 197 N| 196 P| 1068 T| 1116 U| 1040 V| 538 W| 532 X| 396 Y| 2039 Z| 109 010
Benjamin Cornish @mathematicians-pod.bsky.social · 12/12/2025Here is a headshot of me made up of 120,000 pentominoes, each given a single colour, averaged against the original jpeg. The 10,000 'tiles' contain all 12 pentominoes and are randomly selected from the available 2339 ways to create a 6*10 tile. Still a work in progress... 030
Benjamin Cornish @mathematicians-pod.bsky.social · 12/12/2025I very nearly did something interesting 000
Benjamin Cornish @mathematicians-pod.bsky.social · 12/12/2025My daughter and I were outraged this morning watching #ShauntheSheep The goat unwinds the post and eats the grass in an unmistakable Archimedean spiral. What do you think should have happened ? #mathsky #kidmaths 210
Benjamin Cornish @mathematicians-pod.bsky.social · 07/12/2025Apparently you don't get to choose when you start a new obsession... #logic #riddles #nospoilers #threegods en.wikipedia.org/wiki/The_Har... 010
Benjamin Cornish @mathematicians-pod.bsky.social · 07/12/2025For anyone who needs a contour map, for a bit of light relief. Here is a picture of watermelon virus. #mathsky #mathsinthewild 1142
Benjamin Cornish @mathematicians-pod.bsky.social · 27/11/2025I just saw a product advertised as 12 kilo watt hours per 1000 hours. So... 12W ? #mathsky #realworldmaths #unitsgore 110
Benjamin Cornish @mathematicians-pod.bsky.social · 24/11/2025TIL why you cannot construct a regular heptagon with compass and straight edge. I'll tell you all about it on the next episode of #Un-NaturalNumbers which we record tomorrow. Very excited! #mathaky #chebyshevpolynomials 010
Benjamin Cornish @mathematicians-pod.bsky.social · 21/11/2025A person on #Reddit asked if one person could survive an apocalypse with only the contents of a supermarket for the rest of their lives (ignoring expiry dates) What was the last #FermiApproximation you did ? #mathsky #mathstalk 100
Benjamin Cornish @mathematicians-pod.bsky.social · 13/11/2025I am wondering if I have a problem with #oeis searching... It's becoming obsessive #mathsky 030
Benjamin Cornish @mathematicians-pod.bsky.social · 04/11/2025I just had a letter box delivered... Which uses up my irony budget for the week. 000
Benjamin Cornish @mathematicians-pod.bsky.social · 21/10/2025It turns out it's really hard to draw #Isometric paper by hand. My teacher always told me I wouldn't walk around with a protractor in my pocket, and it turns out she was right. In other news, I might have discovered a new #OEIS Spoiler: 1, 6, 18, 45, 87 #mathsky 000
Benjamin Cornish @mathematicians-pod.bsky.social · 20/10/2025I do love it when I am browsing the #OEIS and I find a comment that was within the last few weeks. Oddly titillating to know that someone else passed this way so recently. oeis.org/A011545 #mathsky 050
Benjamin Cornish @mathematicians-pod.bsky.social · 10/10/2025Another lovely night playing "conservation of energy" with my daughter. The box says 8+ but I would easily give it a 10/10. #mathsbuild #classicalmechanics #mathstoys 010
