toby talks
For fun, I occasionally stand up in front of groups of people and talk about science and maths. I love explaining interesting ideas, and telling exciting stories to audiences who may not be that familiar with the subjects.

I’ve spoken not once but twice in front of the world-famous Boring Conference in London, which got me write-ups in the Telegraph, Guardian, and The Sun. The Grauniad spelt my name wrong, so I know I’ve arrived. I’ve also spoken at Science Showoff as part of the British Science Festival at the University of Birmingham, and at the wonderful Westonbirt School in the Cotswolds. There was supper and wine after that one. It was lovely.
the square root of two
My “signature talk” is called The Square Root Of Two. It’s the story of a simple four-sided shape that hides a terrifying secret, some vegetarian ancient Greeks, and a MURDER. Oh, and my cat Fatwans is in it quite a lot too. There IS some simple maths, but I display a large warning triangle and play a klaxon sound first, so nobody can say they weren’t warned.

There’s a short fifteen minute version of The Square Root Of Two, or an even better and longer (about fifty minutes) version where we do some physics (the radioactive Demon Core), chemistry (the Poisoners’ Corridor), and biology (wait and see) before I launch into the story of one of the scariest numbers that exists.
I also have a slightly more technical talk about calendars, in which I tell you a little bit about the history of our calendar, and explain why every single packet of Walker’s Crisps goes out of date on a Saturday. I’ll teach you how to work out the day of the week for any given date in history, which can be done in your head, with a little bit of practice.

These talks come with the best Keynote slide shows you’ve ever seen, at no additional cost. I just need you to provide a projector and screen - I’ll bring my own laptop. If you’d like me to speak at your event, school, or in your living room, send me a message.
