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.

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!

The irrationals are those exactly those reals that are a different distance from every rational.

@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)
