Maths in the Spiderman: No Way Home Credits

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.

In this series of posts, Katie investigates simple mathematical concepts using the Google Sheets spreadsheet app on her phone. If you have a simple maths trick, pattern or concept you’d like to see illustrated in this series, please get in touch.

It’s been a while since we’ve had an entry in this column, but the other day I was sent a link to a very interesting spreadsheet (which I, of course, opened using the Google Sheets app on my phone). The initial view was a pleasing pattern of squares, in two colours:

Since we’re all busy people, sometimes news and other interesting bits of maths don’t get reported quite as they happen. Here’s a few stories that slipped through the cracks over the summer.

Doodling for π day

It’s that time of year again – 3.14 (March 14th), a.k.a π day, is just around the corner, and if you want to do something fun on the day, now’s the time to plan it. One nice way to celebrate this brilliant infinite string of digits is by creating π-inspired art, and we’ve spotted a couple of relevant links if that’s your jam.

  • Maths learning organisation (and Carnival of Mathematics stalwarts) Ganit Charcha are running a competition for schools in India, challenging them to ‘Doodle for π‘ – students should take inspiration from a mathematical concept, and create a doodle/image to submit. The competition invites creativity and imagination, and runs until 12th March.
  • If you’re not in India, you can still use π as inspiration for artworks – Think Maths speaker and Aperiodical Math-off contestant Zoe Griffiths has put together a set of ideas for how to use π to create beautiful pictures, to decorate your home, school or office.

HLF Blogs – Math ⇔ Art: the Gosper curve

This week, Katie and Paul are blogging from the Heidelberg Laureate Forum – a week-long maths conference where current young researchers in maths and computer science can meet and hear talks by top-level prize-winning researchers. For more information about the HLF, visit the Heidelberg Laureate Forum website.

Running alongside the 5th HLF is an exhibition of mathematical art by the astrophysicist Aldo Spizzichino. He’s taken ideas from mathematics, and used his own set of programs (in Fortran, no less) to produce his images, a couple of dozen of which are on display in the Old University building a few steps from the forum. Although all the pieces were generating discussion as I looked round the exhibition on Sunday morning, I’ve picked two to talk a bit about, both based on the same piece of maths.
