Peter suggested it, so Katie had to do it: here’s a video of Katie and fellow maths/Marvel fan Jimi watching through the end credits to Spiderman: No Way Home (warning: contains spoilers for the film) and talking about the mathematical things found therein.

Integer sequence review: A101544
It’s nine years since the first integer sequence review, and six years since the last one. We’ve grown as people, and in CLP’s case, grown people. The world has changed, but our love for the Online Encyclopedia of Integer Sequences hasn’t.

What does DALL·E ‘think’ mathematics and a mathematician looks like?
DALL·E is an Artificial Intelligence (AI) system that has been designed to generate new images given a text prompt. It’s very much like doing a Google image search with one very important difference: DALL·E doesn’t try to find existing images to match your query, but creates a handful of new ones that it hopes will fit the bill.

Sequences in the classroom
Guest author David Benjamin shares some of his favourite ways to use sequences in a teaching context.
As a maths teacher, I’ve found that sequences are a great way to engage and inspire mathematical reasoning. I thought I’d share some examples of sequences, and sequence-related activities, I’ve used with success in the past.
Carnival of Mathematics 207
The next issue of the Carnival of Mathematics, rounding up blog posts from the month of July and hosted by Sam, is now online at SamHartburn.co.uk.
The Carnival rounds up maths blog posts from all over the internet, including some from our own Aperiodical. See our Carnival of Mathematics page for more information.
Presenters wanted: a series of public maths talks by disabled mathematicians
I’m organising a series of online public maths talks through my work, the School of Maths, Stats and Physics at Newcastle University.
The point is that talks will be delivered by disabled presenters. This came about because I and some other disabled people who do maths talks got tired of missing out on opportunities to do outreach because it involves travelling. Not every disability makes travelling harder, but we felt that there were enough people excluded by in-person events that it would be nice to put on a more accessible event.
My aim is for this to take place in December 2022, near to the International Day of People with Disabilities. Talks can be any mathy topic, or about your experience as a disabled mathematician.
I need speakers!
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 syndrome.
I might talk about:
The sessions will be delivered over Zoom, with live captions written by humans and a BSL interpreter. (If you can recommend a BSL interpreter with experience of interpreting maths talks, please get in touch!)
We’ll be advertising the talks to the general public, both grown-ups and schools, so I’m not looking for talks about high-level maths or education research.
This is open to anyone around the world, but if you’re a long way from the UK bear in mind that we’ll schedule the sessions at a convenient time for a British audience.
If you’re interested in taking part, please email christian.perfect@ncl.ac.uk.
I’d like to have a list of presenters by the end of September, to leave plenty of time to arrange whatever needs to be arranged and to advertise the talks.
