Possibly the only person to hold the prestigious title of London Mathematical Society Popular Lecturer while simultaneously having a sold-out comedy show at the Edinburgh Festival Fringe, Matt is always keen to mix his two passions of mathematics and stand-up. He is part of the oddly popular Numberphile channel on YouTube, where his videos have reached over 25 million views, and is also edging towards a million subscribers for his own Stand Up Maths channel. But he is not against old media and appears regularly to talk about maths on Discovery’s Outrageous Acts of Science and BBC Radio 4’s More or Less. Matt is also the author of Things to Make and Do in the Fourth Dimension and the Sunday Times Bestseller Humble Pi: A Comedy Of Maths Errors, both published by Penguin. His favourite number is currently 4,900.
