Do you know the game Hex? Do you use \(\LaTeX\)? Chris Sangwin & I wrote a package for drawing Hex boards and games called hexboard. It makes lovely diagrams like this.

I see people are doing #Introductions.

I teach university mathematics (modelling, combinatorics, game theory, history, programming) in the UK. I also research university-level educational practice. Recent papers including teaching programming, automated assessment & play and problem-solving: https://peterrowlett.net/publications

I'm one of the editors at @aperiodical.

I'm a Vice President of https://ima.org.uk/

I co-host a podcast Mathematical Objects with @stecks https://aperiodical.com/podcasts/mathematical-objects/

Because a lot of people are talking about Mathstodon on Twitter, I remembered it exists and logged back in (with a little help from @christianp). I continue to like Mathstodon and am happy to be here but generally forgot it exists. Is there a good Mastodon app anyone can recommend? That might make it easier to remember to come here.

Currently a lot of my time is preparing for and running vivas for final year undergrad projects. Last week some game theory (Nim), yesterday's was about GCSE maths curriculum content, today it's fractals on the complex plane.

‪Quote is from the latest BBC More or Less episode on Radio 4 (though a similar claim was made on the World Service edition of the programme). But isn't self-similarity about similarity at different scales, i.e. parts resembling the whole? Am I wrong?‬

Okay, that wasn't pretty, but I felt #proofinatoot was being quite number theory-y ;)

\( (u(x)v(x))'=\lim_{\delta x\to 0}\frac{u(x+\delta x)v(x+\delta x)-u(x)v(x)}{\delta x}. \)
Add and subtract \( u(x+\delta x)v(x) \) in the numerator. Then
\( (u(x)v(x))'=\lim_{\delta x\to 0}\frac{u(x+\delta x)v(x+\delta x)-u(x+\delta x)v(x)+u(x+\delta x)v(x)-u(x)v(x)}{\delta x} \)
\( =\lim_{\delta x\to 0}u(x+\delta x)\lim_{\delta x\to 0}\frac{v(x+\delta x)-v(x)}{\delta x}+\lim_{\delta x\to 0}\frac{u(x+\delta x)-u(x)}{\delta x}\lim_{\delta x\to 0}v(x) \)
\( =u(x)v'(x)+u'(x)v(x). \) #proofinatoot

@christianp any use? https://octodon.social/users/jannamark/updates/90593

Oh crumbs, first day back in the office yesterday and I forgot Mastodon existed. Mostly did email, student queries and marking; you didn't miss much.

I enjoyed "I learned some math on the streets" https://mathstodon.xyz/@bremner/289

Followed a few people who used #math and #maths, since I teach that.
