QEPrize’s Month of Making
The Queen Elizabeth Prize for Engineering celebrates innovation in engineering with an annual prize awarded to some of the world’s top engineers. Starting today, the QEPrize YouTube channel will be hosting a Month of Making, with a video each day supplied by a different STEM person (including some mathematicians!), encouraging you to make, instead of buy, at least one Christmas present this year.
The month has been organised by physics teacher and STEM communicator Alom Shaha (who recently featured on our Mathematical Objects podcast). Alom says:
I want other people to experience the joy I find in “making” by encouraging them to make stuff for the people in their lives. Christmas feels like the perfect time to do this and, with the help of the people behind the Queen Elizabeth Prize for Engineering, I’ve somehow managed to recruit a bunch of incredibly creative and talented people to share some ideas for things you could make. Over the course of the next month or so, from 15 November to 12 December, we’ll be publishing a series of videos with simple instructions for making a range of gifts, from simple machines to pieces of jewellery.
There’s also a competition running to win a copy of Alom’s book, Mr Shaha’s Marvellous Machines, for anyone who makes one of the suggested gifts and shares a photo or video of it with the hashtag #AMonthOfMaking.

Clopen Mic Night – new online maths variety show
The team that brought you the 24 Hour Maths Magic Show last October are at it again, and are planning a semi-regular evening YouTube variety show called Clopen Mic Night, with short segments from a selection of mathematical guests, including comedy, music, demonstrations, magic, puzzles and art, showcasing some top maths communicators and hopefully providing a fun night in. The event is supported by Talking Maths in Public, a network for maths communicators based in the UK, and this first show will take place alongside their 2021 conference event.
It’s called Clopen Mic Night because it’s both an open mic night (in the sense that you’ll see a variety of different people doing different things) and a closed mic night (in that the organisers curate the line-up to ensure a variety of quality acts). If you’ve not encountered the concept of a clopen set, it describes a set that is both open and closed. Usually things are clopen for tedious technical reasons – the empty set and the whole set are both trivially clopen, and most interesting examples crop up in awkwardly-defined sets with non-standard topologies and distance metrics.
The first event is taking place on Thursday 26th August, from 8-9pm, on my YouTube channel, and you can watch along for free, join in with the chat, and drop a coin in our virtual tip bucket if you like what you see. This will hopefully be the first of many such shows (assuming it all goes well!) and for future shows we’ll be looking for acts to join us – anyone participating will also be able to get advice and feedback on their bit in various ways, and we’re hoping it’ll be a chance for people to try out fun new material and showcase the best maths communication has to offer.
For more information about the show, including the lineup for this first event, you can visit the Clopen Mic Night website and sign up for a reminder before each show so you don’t miss it. For updates on future events and how to apply to perform (once that becomes a thing), check the @ClopenMic twitter account.
