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 built my solar model using an incorrect gear system... The planets are in complete disorrery. 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 · 03/08/2026The latest episode of #themathematicianspod this time it's another double bill with Varahimihira and Bhaskara I. ...And what's that... Mainly an episode about geography? I'll grab the popcorn. #mathshistory #talkingmathspodbean.comEpisode 59 - Varāhamihira (And Bhāskara I) - Back to SchoolWas Varāhamihira the world's first statistician? Could a sixth-century mathematician really predict the monsoon using observational data? And how did Bhāskara I produce one of the greatest approximati... 021
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 000
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 · 28/07/2026Warning, bad science joke: Why was Aristotle's house so dusty? Because his nature abhorred a vacuum. 000
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 · 25/07/2026I'm still working on how to answer it in terms understood by a 16-18 year old, but I think we can clarify every pair of lines as parallel or not... I'm getting a bit stuck on why 1 is possible, but 2 not... 100
Benjamin Cornish @mathematicians-pod.bsky.social · 25/07/2026If we assume the lines are infinite in lengths, on a flat plane, then I don't believe it's possible. 110
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 · 10/06/2026New episode is live, of #themathematicianspod. A much longer production process for my longest scraped episode. This time featuring the snorts and sniffles of my new baby asleep on my chest. Tune in to learn about merchants and maths in #ancientindia, with Yavanesvara. #talkingmaths #mathskymathematicians.podbean.comEpisode 57 - Yavanesvara - The Lord of the Greeks | The Mathematicians PodcastThe Silk Road carried spices, gemstones, ideas... and, occasionally, trigonometry.

Benjamin Cornish @mathematicians-pod.bsky.social · 21/05/2026Gosh. I've just recorded the latest episode of #themathematicianspod with a raw time of 46 minutes. A record for me with a scripted episode. Hopefully the story of #yavanesvara will be worth it. Coming to you in probably 2-3 weeks. 000
Benjamin Cornish @mathematicians-pod.bsky.social · 20/05/2026I've just started listening to a fantastic #podcast on the #historyofengland by @historyengland.bsky.social I cannot recommend it enough for style, clarity and wit. Great job, David! 120
Benjamin Cornish @mathematicians-pod.bsky.social · 18/05/2026Thank you. Will probably be my only attempt at poetry. But we shall see. It's back to dense history and unintelligible calculations in the next two episodes. Phew! 210
Benjamin Cornish @mathematicians-pod.bsky.social · 17/05/2026Hey, it's my birthday today. But please don't feel embarrassed that you didn't get me anything, all I want for my birthday is for you to enjoy today's new episode of #themathematicianspod. This time, Pingala, and a 10 minute beat poem... Please forgive me. #mathsky #mathshistory #poetryopen.spotify.comEpisode 56 - Pingala - Beats us up 131
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 · 03/05/2026I've been reading 'James and the giant Peach' with my daughter. Spoiler alert: Does anyone know how many seagulls it would actually take to lift up a peach the size of a house? 000
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 · 20/04/2026Why, it's another episode of #themathematicianspod this time an interview episode with the fabulous @teakayb.mathsy.space, author of #themathrmaticianslibrary.

Benjamin Cornish @mathematicians-pod.bsky.social · 17/04/2026I've just finished watching "Death by lightning" on Netflix. They appear to have missed the most interesting aspect of the #POTUS 's life, that President Garfield developed his own distinct proof of #Pythag, one without using any squares. Otherwise a good watch. #mathsky #somepresidentswereclever 020

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 · 03/03/2026A non-prime-power is a number not written as p^k where p is prime and k is a natural number. 000
Benjamin Cornish @mathematicians-pod.bsky.social · 03/03/2026Try this. Take a number, n, split it into proper prime divisors. Write those, ascending, as the place values for a new term base n. Repeat this recursively. I think only 3 non-prime-powers will terminate. 10-> 25_10 25-> 5_25 5->0 12-> 23_12 27-> 3_27 3-> 0. What is the third number? 210
Benjamin Cornish @mathematicians-pod.bsky.social · 03/03/2026ACB? How does this scale with higher n-gons? What about a cube or higher dimensions? 110
Benjamin Cornish @mathematicians-pod.bsky.social · 26/02/2026Competition time: A sequence stats 1, k, ... Each new term is the product of the last two subtract the sum of the other previous terms. Which sequence grows faster k=1 or k=2 ? #oeis oeis.org/A117030oeis.orgA117030 - OEIS 100
