Christmas Decs are already in the shops. Anyone want to play a game of "Reverse Mechanical Linkages"? #Mathsky #Mechanics

A contentious opinion: A4 #origami is superior to square form, as you can connect two A4 sheets for a 41% larger di-tonal construction. 1:1 ratios can suck it #mathsky #mathsbuilds

Is everyone ready for #mathober? #mathober2025 I am looking forward to everyones takes, art, musing, jokes, etc. Mathober has no rules - do 1 day or 35-or just follow along. Blog: www.fractalkitty.com/mathober-2025/ Just the prompts: mathober.com #indieweb www.fractalkitty.com/content/imag...

www.desmos.com/calculator/a... Hi @fractalkitty.com, My attempt for day 1 of #mathober with the prompt #link. I was inspired by the loops created by rows of crochet, and tried to render this using a parametric plot. Maybe someone with better crochet skills than me could do a realistic pattern.

Wouldn't it be awful if the first 3 recorded Women in the #HistoryofMaths were lost. At least we get the 4th - Hypatia. SPOILER: her story does not make the patriarchy look any better. Would you like to know why? #mathsky #womeninmaths #themathematicianspodcast www.podbean.com/eas/pb-suv8d...

At some point I need to stop pretending that I am teaching my daughter maths, and just admit that I like #Duplo #mathschat #mathstoys #buildingmaths

I'm not sure anything has emphasised inflation or the cost of living crisis to me more than watching an old episode of #granddesigns from 2009 and seeing their budgets.

So, I'm thinking that Pappus of Alexandria is the first recorded bit of Mansplaining. Here he is trying to tell the lecturer Pandrosion how to do geometry. Sadly this is one of the only references to one of the 4 female Mathematicians before Hypatia. And it leads me to call him Papp-ass #mathsky

How many integers, n, are there, such that n!+1 is a perfect square? Find out on this week's #TheMathematiciansPodcast where we look at Diophantine equations and the man who started them. Could this be the birth of modern algebra? Nearly. #mathstalk #mathsky open.spotify.com/episode/3i3K...

I know I say this a lot, but I was genuinely delighted recording Ptolemy's episode of #TheMaathematiciansPodcast . As it turns out being wrong can sometimes be more helpful than being right, if the goal is to teach people how to think. www.podbean.com/eas/pb-tpxcy... #mathschst #mathsky #podcast

Hey. Guess who very nearly has made it onto the front page of apple podcasts 'Mathematics' list. It's #TheMathematiciansPodcast. Watch out @timharford.ft.com , I only need to get a few million more downloads weekly to steal top billing. Admittedly this "more" is multiplicative not additive.

My mini-bag of skittles had 17 skittles in it with 4 colour options. AM I THE ONLY SANE PERSON LEFT IN THIS WORLD?!?

Just bought a book on optics, for a bit of light reading

Episode 5 of #Un-NaturalNumbers the maths chat show just dropped. In what is arguably our largest number so far: 5. Join me, @hopeiona.bsky.social and Jocelyn to discuss our favourite facts about the number 5. #mathschat #mathsky #msthstalk youtu.be/i-oAWhc5SH0

Was he a Platonic Pythagorean, or a crank? You decide, as we explore Nicomachus in this week's #TheMathematiciansPodcast He's the guy that thought numbers had such well defined personalities, that he wrote a mandetory textbook for the next 1000 years www.podbean.com/eas/pb-w79nx... #mathstalk

I'll be at @tmip.bsky.social later this week, which gave me the perfect excuse to finally soft launch my YouTube channel, where I learn to be a better maths communicator by analysing some of my favourite YouTube creators! youtu.be/1UbjqEWc__0?...

What's this? Oh it's episode 4 of #Un-NaturalNumbers With the magnificent @steckl.es and @paddymaths.bsky.social. Give it a watch if you're in the mood for Klein groups, Harshad numbers and Modulo 4 arithmetic. #mathstalk #mathschat #talkingnumbers youtu.be/RfNBjhHGJ54

ACK! Another #MathArt post! I'm on a roll. Mainly because I'm trying to distract myself from the reality that school is starting up soon for me. Here's my embroidered aperiodic tiling. samjshah.com/2025/08/19/e... Instructions from: www.threadedtheorems.com/aperiodic-ti... #MTBoS

Just finished recording episode 5 of #Un-NaturalNumbers, with the wonderful @hopeiona.bsky.social and Jocelyn D'Arcy. I dare you to calculate n^5 mod 10, for n<10 Go on. A really great set, looking forward to publishing #mathstalk #mathschat

I am very delighted to present my latest interview for #TheMathematiciansPodcast I talk to Dr Daffern about the intersectional history of #maths + #religion www.podbean.com/eas/pb-f9vg6... Bring your skepticism and doubt and be amazed at how the two topics link #mathschat #talkmaths #philosophy

I was playing crazy golf with a bunch of topologists, but they kept arguing over the definition of a hole-in-one.

If I say: Any square (4*4 or 8*8) may be rotated by 90 degrees, if the pieces are fully enclosed in the square. Is it possible to sort all the greens to the left and reds to the right? #playmaths #mathschat #mathsky

Here is my Duplo castle. Can anyone suggest some Duplo based maths that I can use to enhance my daughters play time? #playmaths #mathschat

Spoiler for my next YouTube video. Can you guess what it's about? #mathsky #briotrains #railwaymazes

Getting ready to interview Dr Daffern on the intersectionality of ancient maths and ancient religion for #TheMathematiciansPodcast. Very much looking forward to episode 33, check it out in 2 weeks. #mathstalk

Hey who invented #Trigonometry anyway? Good question, come find out on this week's episode of #TheMathematiciansPodcast. Wouldn't it be cool if he was the same guy who first identified a supernova, well if you insist #mathstalk #mathschat #mathshistory mathematicians.podbean.com/e/episode-31...

Would anyone like to join me on the 6th of August to do episode 5 of #Un-NaturalNumbers the #MathsChat show all about the number 5. Would you enjoy sharing your favourite facts about 5 + An evening of delightful conversation with fellow maths enthusiasts #mathstalk forms.gle/nbVi7dezTNUp...

Episode 3 has just dropped of #Un-NatrualNumbers, with excellent contributions from @hopeiona.bsky.social and @christianp.mathstodon.xyz.ap.brid.gy If you are looking for a #MathsChatShow then check this out: youtu.be/hZ9l5fF2x4w #mathstalk #mathsky #KnotTheory #SetTheory #PalendromicNumbers

My first double bill of Mathematicians. Genius but not so prolific, and not to be ignored Would you like to know who wrote book 14 of #Euclid's Elements? Did you want to see #integralcalculus before Newton? Then tune in #mathstalk #mathsky #podcast mathematicians.podbean.com/e/episode-30...

Very excited to record episode 4 of #Un-NaturalNumbers tonight with the fabulous @steckl.es and @paddymaths.bsky.social. Tune in soon to YouTube for some fun facts about the number 4. Or get in touch if you want to be a guest on a future show, open invite to all. #mathstalk #mathsky

So I am camping with a second hand gas canister. I have not been told how full it is, or how many hours of cooking it should last. I can hear a 'slosh' when I shake it. What mathematical steps would you take to estimate how many kettles I can boil? #talkmaths #mathsky

Moving up one dimension into Apollonian sphere-packing using POPs. I put together an implementation based on Kean Walmsley’s code, which itself is built on Ron Peikert’s original work from his paper “The Fractal Dimension of the Apollonian Sphere Packing.” #creativecoding #generative #generativeart

My latest #MathsYouTube video is up. In this one I look at the 'Lies' of modelling in relation to pendula, and explore things like the small angle approximation, or the 'flat earth' of gravity. Which model is better: pure or useful, you decide! #alevelphysics #mathstalk youtu.be/8URfRjeuHA0

Potential fact for episode 4 of #Un-NaturalNumbers . I spent most of my final minutes before falling asleep last night trying to think of a 3 digit Harshad number. This gives a deeper insight into the rule of divisibility by 3. #mathstalk #mathsky

A Pappus Chain. An Arbelos-related chain of tangent circles between two tangent circles created with an inversion of a chain of circles between two parallel lines.

Hey, I just dropped my 27th episode on the history of Mathematicians in chronological order. Check out Apollonius, on conics. One of the whales of ancient greek maths. #mathstalk #mathsky #themathematicianspodcast www.podbean.com/ew/pb-j9r4c-...

Holy smokes Batman. And this just happened to be published in the month that I needed it.

Just brushing up on my knot theory ahead of #Un-NaturalNumbers the maths chat show all about numbers. Tomorrow we record episode 3, on the number 3. And I am planning to talk on knot theory. See if you can find the significance, and whilst you wait have a go at this #mathstalk #mathsky

My #probability #starter for today's lesson: If I roll 2 dice numbered (0,n) and place them next to each other, we can check if they are prime. But for what value 0<n<10 is the probability of a prime greatest? #alevelmaths #mathsky

I just downloaded my own pdf of The Principia, this has given me a curious feeling, like reading a religious text. Below is B 1, S 5, L 17: where I will be making the case that Newton is citing Apollonius for his work on Conics. Free copy: web.math.princeton.edu/~eprywes/F22... #mathsky #mathstalk

One of my favourites of my daughter's toys. 10 points to the first person who can do me a "Maths" of this. #mathsart #mathart #mathschat #accidentalmaths

I will also submit this as a great example of #mathart Here we have 8 solutions to the Apollonius problem. Given any 3 circles, draw a fourth that is at a tangent to each. #mathsky

I'm researching Apollonius ahead of next week's #TheMathematiciansPodcast. I would love to say I'm using this as the source material, but we all know that's a lie. It's still beautiful to see a 9thC book that looks like it could easily be a modern student's notes. #alwaystrue #mathsky #mathstalk

My new favourite quote to give to a student: 'Sir I don't understand...' #alevelmaths #mathsky #mathschat

Delighted to bring you an episode on #Chrysippus If (you are a fan of formal logic): Then (you should listen along) +Some extra bits on moral philosophy from the 'Second Father of Stoicism' mathematicians.podbean.com/e/episode-27... #mathsky #hisyoryoflogic #TheMathematiciansPodcast #ifthen

Having a breakdown on camera you say? See if you can guess the topic of my next video. #mathschat #mathsky

I've just got out from teaching a class on logic so formal I had to wait a tux. Luckily there is an episode dropping tomorrow of #themathematicianspodcast on #chrysippus. #mathschat #mathsky

Have you ever wondered what it looks like when a lion chases a penguin in space? Wonder no more, as I answer that question in this week's #MathsAnimationTMiP. Very much a #sillymaths video, but some very retro screensaver vibes. youtu.be/yKSjt0eGark #mathsky @tmip.bsky.social

Genuine question: I went rowing up a river. The river flows at 2km/h. When I didn't row I moved at 5km/h with the river and wind. When i went up river it took me 55 min to paddle 500m upstream, i then came at the same speed back in 5 min. How fast was I going? 1km/h 3km/h 4.2mk/h Other #mathsky

Very excited to share Episode 2 of Un-Natural Numbers. The #mathschatshow all about a single number, this week the #number2. With fabulous guests @kisonecat.com and Cindy Jiao youtu.be/N53Vvz6cCAE I'm now looking for guests for episode 3, give me a shout if you're interested. #mathsky #mathschat
