Fulltime freelance provider of outreach and enhancement in maths ... I talk a lot. About maths.

I talk about other stuff too, like ballroom dancing, juggling, unicycling, education, engineering, software, and "other things".

But mostly about maths.

I tend to follow back, but only if you have something in your profile.

Huge sigh of relief ... in a rush, but several possible pitfalls avoided largely by chance ...

@bencurthoys It happens to us all! You should see some of the nightmares I've had.

I've made notes, I should dig them out and make them visible.

Just made a substantive comment on The Orange Site, and as a bit of whimsy used "swutch" as the past tense of "switch", and I do with "lunk", "cluck", and "drug" to be the past tenses of the verbs "link", "click", and "drag".

Within seconds, two replies, ignoring the bulk of the comment and correcting my grammar.

Not surprised ... we'll see how it plays out.

Simple curiosity ... does anyone recognise this? Is it meaningful?

@mndflayr I wonder if it's a Game of Thrones thing or something, some sort of fantasy game or film merch.

It might be a simple substitution cipher into the runes of the relevant fantasy world.

Or it might just be a designer saying "This looks cool".

@timhutton So ... simple substitution cipher?

Hmm.

Suspicions confirmed. Good work ... thank you!

Desperately sad to learn of the death of Douglas Buchanan after a short illness.

A tireless promoter of maths, an extraordinary teacher, he created brilliant events and reached hundreds of thousands.

A very sad loss.

Very sad.

@soaproot Nice.

I have another theorem that you might be interested in. It has a longer setup, specifically because I want to share the unexpectedness I felt about the result. The result itself is easy to prove in the usual informal manner ... perhaps you'd be interested in formalising it.

(An answer of "no" is, of course, acceptable)
