I'm trying to fly less. But it turns out I didn't have a clue and who flies and how much. Fewer than 25% of people fly more than once a year. 50% of people don't fly each year.

Today we looked at a group on subsets of a set. Lots of discussions about the validity of a proof. And a great question: if I can find an identity for a single element and state that identities are unique then does this show we have an identity for the group?

#extrapure lesson three weeks review some groups and non-groups from modulo arithmetic, discussing the Latin square property. I introduced the group of transformations on an equilateral triangle. Then we looked at permutations on 3 things. Are these two the 'same'? What about addition mod 6?

This is near me. In fact, I've never seen anyone using the goal and I can't remember seeing it without cars in front. Should there be some graffiti saying "kids not cars", "play not parking" or "ball games allowed"?

#CoreMaths AQA Preliminary Material, P2. Tried an idea in lesson today and it worked really nicely. Partially inspired by @lilytgmaths.bsky.social . Happy to explain it more but hopefully this covers it.

When it's 20% *that we know about* it's not a bug, it's a feature. Also, it's rape. #defundthepolice

Wanted to feel a sense of power and purpose this morning. I'm no poet but I wanted to think what 'first they came' would sound like today with the knowledge of the last time fascists were in power.

It's a good thing that Labour are focused on doing things and not on winning votes. It's not 'lucky' it's how things are. Idiot.
