Seems to be another round of declaring ourselves elsewhere. I’m mostly not here, mainly hanging out at Finite Group finitegroup.co.uk - join the chat community for free.
Otherwise, I’m @peterrowlett@mathstodon.xyz

Had a lovely day today — we ran an outreach event for year 12s from around Sheffield for Maths Week England - mathematical modelling, puzzles, problem solving, and lots of applications and careers maths leads to.

.@Ayliean has taken the opportunity to mention the new Can Humans Say The Largest Prime Number Before We Find The Next One project, details of which are at saytheprime.com
and overlapping an emirp and its reversal (e.g. 131, which is 13 and 31). He wrote some code and found all the primemirps under ten million!

The primemirps Peter found are now in OEIS: oeis.org/A054218

We start our penultimate session of the day with @PeterRowlett, who heard @stecks talk about primes in a FiniteGroup.co.uk livestream, which got him playing with emirps - primes which are still prime with the digits reversed, and primemirps - obtained by concatenating

.@stecks and I stare deep into an area the size of Wales and draw mathematical inspiration from the experience. And have some fun with silly units.

I wrote about queuing in this weekend’s @newscientist! And I wrote this week’s puzzle exploring a technique involving multiplying a number’s digits together.

Form an orderly queue
From shops to ride-share apps, queuing is everywhere.
Peter Rowlett explains how maths can make it more efficient
I imagine that you may, at some point in your life, have been in a queue that wasn't run entirely efficiently. Despite allegedly loving to line up and wait for things, Brits like me have an array of stories about badly run queues.
Luckily, maths can give us insight into queues and answer questions like how many staff are needed to help them run efficiently. We can gather data on a real queue and use the average arrival rate to calculate the probability of someone joining.
This is just an average, of course: if I told you an average of six people were going to enter your shop every hour and six arrived in the first few minutes,
For free, you can now sign up at patreon.com/FiniteGroup to join us in a fun, friendly maths community. You can also pay to access monthly livestreams either as a subscription or pay-per-view, and other benefits.
You may have seen me going on about being in the Finite Group - a Discord with monthly livestreams of fun people (@peterrowlett@ayliean@mscroggs) talking about maths - and now joining the Discord is now free! Join here to find out more: patreon.com/posts/free-membe…
What is maths? Who is it for? Where can it lead you? We offer more diverse answers to these questions than students might expect in this sixth form event for Maths Week England @maths_week.

This week's Finite Group livestream highlight is me responding in shock when @stecks does some error correction. Join at patreon.com/FiniteGroup if you want to be there the next time something this exciting happens. youtube.com/watch?v=cCtlCXVV…
Read nine articles published during the 60 year history of the Institute of Mathematics and its Applications, each with a new introduction. Includes Lighthill on animal flight, Ollerenshaw on Rubik's Cube & Wilkinson on numerical error.

A Finite Group livestream highlight - @Ayliean has translated some fundamental theorems into emoji for @stecks to guess.
Don’t miss out on the October livestream - join the group at patreon.com/FiniteGroup
Enjoying listening to @stecks talk about David Singmaster’s work on the Rubik’s cube at this @mathshistory meeting on recreational mathematics. Slide is a page from his seminal ‘Notes on Rubik’s Magic Cube’.
