Just want to say, I recognised your name immediately when I saw it. Saw a talk you gave at the Institute of Education in Bloomsbury back in 2010 when I was a teenager and it is still, to this day, one of the best popular mathematics talks I've ever witnessed (obviously helped by the immense juggling talent).
I've gone on to do a PhD in Physics and write lots of popular science for some big YouTube channels (SciShow, Veritasium) and among some of the more long term influences on my career I definitely count your talk as one of them!
