We’ll be joined for our fifth Clopen Mic Night by the Pseudorandom Ensemble, a mathematically-inspired musical combo who are experimenting with the form of online collaborative musical performances and exploring what it means to be normal. More info at clopenmicnight.com

Our next confirmed guest for Clopen Mic Night 5 is Yolanda Ohene, who likes doing research into neuroimaging, and going rollerskating (but not at the same time, as far as we know). More info at clopenmicnight.com

The remaining performer for the Clopen Mic Night: Power of Five (clopenmicnight.com) is Mats Vermeeren, who’s a research fellow and lecturer at Loughborough Uni, and will be asking, “What if everything in the universe started shrinking?” More info at clopenmicnight.com

Not long to go now until the next Clopen Mic Night! Grab yourself a brew (of whatever kind you prefer) and watch our live online maths show from 8-9pm GMT on Thursday 1st May. More info at clopenmicnight.com

It's starting in an hour! Join us from 8pm for an hour of mathematical variety acts, including speculation, calculation and maybe some improvisation - head to clopenmicnight.com for the link to watch live, or catch the recording afterwards.
