I joined YouTube in March 2006. I started making YouTube videos as a way to entertain my friends. And when I wanted to show them an amusing mathematical bit I could just do it to video. Amazingly other people watched, and my subscribers grew. I now have over 200 videos on YouTube over various channels and is probably what I am best known for – which is weird.


singing banana

singingbanana is my own YouTube channel. It started as a personal YouTube channel with maths videos alternating with videos of me juggling or dancing around my back garden – but the maths seems to have taken over!

They’re made semi-regularly, and it’s just me in my house with a camera on a tripod, making whatever I want. I try to mix it up, sometimes the videos are highbrow, sometimes they’re puzzles or magic tricks – whatever I feel like making.

Some of my favourite videos include the Motorway Problem, New Wikipedia Sized Proof Explained With a Puzzle (Erdos Discrepency Problem), and Maths Puzzle: Back to Black.

Why singingbanana, somewhere in my videos I answer that question. Now you have to watch them all.

I miss the dancing around videos.



In 2011 I was contacted by video journalist Brady Haran about the possibility of making a new maths channel. I was a fan of Brady’s other channels including Periodicvideos, Sixty Symbols and Bibledex.

We launched Numberphile on what seemed like a mathematically appropriate date of the 11th of November 2011. That’s 11.11.11 (or, if you’re American, that’s 11.11.11, right?)

Numberphile isn’t just me though, it is a team of speakers. Initially each video was about a different number, an excuse to tell some of the interesting stories and aspects of mathematics. We don’t worry so much about that now.

Some of my favourite numberphile videos that feature my stupid face include Infinity is bigger than you think, 17 and Sudoku Clues, and Rubik Cube Combinations. But you should also check out all the videos.

We would never have predicted that numberphile would become so popular, and it now has over a million subscribers, making it one of the most popular channels on YouTube.



I have been a guest on several other channels, these include; The Royal Institution of Great Britain, The Institute of Mathematics and its Applications, and Cambridge University.

I also help out some of my YouTube friends, they include; Scam School – tricks and puzzle for the bar, TyYann – puzzles from a maths teacher in Seoul, and Mismag822 – card trick tutorials, many involve mathematics! And for more maths, I can also recommend Dr James Tanton and Vi Hart.

And to heck with it, here’s a playlist of every video I’ve made – or at least willing to admit to.
