@jsiehler does saying "symmetry" and then leaving the room count as computing it?

@pkra I can stop it happening by adding `font-variant-ligatures: none` to the CSS, so might just leave it there

@pkra weird! I've just got the latest version from github and it still has the bug. There's an issue from 2014 at https://github.com/theleagueof/junction/issues/7. So they must have fixed it but not updated GitHub?

Exciting unintended typography! Using the League of Moveable Type's Junction font, the word "office" looks like "offfice", I guess because it applies an ff ligature and then an fi ligature.

between 1996 and 2015, the only Irish county names given to children born in the UK were:

Cavan (572)
Clare (1062)
Kerry (38)
Tyrone (1445)

Naming Your Child After Irish Counties

Clare: lovely
Kerry: also fine
Mayo: audacious

oh wow, firefox developer tools has a tool to simulate colour vision deficiency and contrast loss! https://developer.mozilla.org/en-US/docs/Tools/Accessibility_inspector/Simulation
Very handy!

@virtuosew really well, thanks! No time for questions at the end, but the kids were really engaged throughout. Almost worth the massive covid risk

@petrilaarne wikipedia says in Sweden a ✓ is often used for "incorrect". No mention of % though - that's interesting! It feels like a tricky symbol to draw, which matters when you're doing a lot of marking!

@y6nH thanks!

Pals, I've just been told that in Japan they don't use ✓ for "correct", they use 〇.
What other symbols for "correct" and "incorrect" are used around the world?

Just for a laugh,
Let G be a graph,
With points called P
And edges called E.
Now draw a line
(just anywhere's fine)
And split up P,
Some for you, some me.
Now look at E,
And how it links P.
If every line
Connects yours to mine,
That graph called G?
Bipartite. QED!

For comparison, here are the slides I used in 2014: https://www.staff.ncl.ac.uk/christian.perfect/outreach-enneahedron-slides/

weirdly, the custom element code I copied from MDN didn't work in Chrome, for <undisclosed reasons>. I've found a way of making it work now

@virtuosew yes, certainly! Good idea

@bmreiniger thanks! Good points

The talk went really well last time, so I didn't want to change too much. One thing I'm really struck by now is that every character in the story, including me, is a white man. I'm not sure what to do about that.

I'll tell the kids that the story took place in a time when you pretty much had to be a well-off white man to dedicate time to maths and have me end up knowing about it.
