Ten years of numberphile - tenberphile. Today we talk friendly numbers, classic numberphile stuff. I'm going to add my notes to the next tweet, including some of the proofs I didn't do in the video.

I've been doing talks with university maths socs this week. I love it. Many students told me they grew up with @numberphile and are now studying maths. That was always the plan. Thank you for inviting me Bristol, Lancaster and Manchester.

The Bullseye Illusion: The blue centre is the same area as the blue rim. It's also a demonstration of a Pythagorean triple. They have the same area because 5² = 13² - 12².

I really want to see a maths discovery centre in UK, but at the moment we have no permanent home. So if you know any friendly millionaires, let them know. (That's not a joke, that's what we need).
