-1 < 1

if a < b then a/b < b/a

so -1/1 < 1/-1


∀S(m)∈{statements s | s describes a mathematician m} ∃ m_0 : ¬S(m_0) is true.

For every upside down A, there exists a backwards E.

Should I edit or leave as it is in this paper:

All dimensional variables are with the `hat' accent, and dimensionless variables without (baht 'at).

Here is something to interest the Maths Crafters out there. I found this on isobelf.wordpress.com which is well worth spending time reading through.

Saw a sign on the bookie’s window saying “Open 11-4”. Great odds. Might put a tenner on as they seem to be open every Sunday

What do you call a magician who loses his magic?


The barman says, "sorry, we don't serve faster-than-light particles here".

To give some idea of what I'm looking for, I'll use myself as an example.
I count myself disabled at least four ways: I'm colourblind, autistic, dyspraxic, and have Ehlers-Danlos.
I might talk about:
1) use of colour in mathematical communication; how red chalk makes chalk-and-talks inaccessible
2) how ambiguously-worded maths problems have stymied me in the past, and how to write them more clearly
3) the word problem in group theory, which is just something I'm interested in

I'm organising a series of online public maths talks through Newcastle Uni's School of Maths, Stats and Physics, to be delivered by disabled presenters, taking place this December.
Talks can be any mathy topic, or about your experience as a disabled mathematician.
I need speakers: dm me if interested!

"Q: Why did the chicken cross the road?

A: The answer is trivial and left as an exercise for the reader."

2 Pa and 5 Pa go into a bar. 3 Pa does not.

There won’t be an Edinburgh in August due to the festival. We will resume on 20th September

If Mahler’s 8th symphony lasts 90 minutes when played by an orchestra of 120 musicians - how long would his 4th symphony take if played by an orchestra of 60 musicians?

Edinburgh Mathsjam is at 7pm in the Brass Monkey (Drummond St - near Blackwells). There is a talk at ICMS at 6pm so you could go there first as it is just 45 min long.

I've never wanted to explain entropy on Twitter, since it's very subtle, and people have lots of crazy ideas about it, which they insist on talking about. I'd much rather explain algebraic topology, where that doesn't happen. But people prefer entropy.
