My name is Brady Haran and the main thing I do is make YouTube videos.

You can see them on channels such as Numberphile, Periodic Videos, Objectivity and Sixty Symbols - plus a bunch more.

I also co-host podcasts called Hello Internet with CGP Grey and The Unmade Podcast with my mate Tim.

I'm on Twitter and you can join my occasional email list for extra stuff.
