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.
Today marks 10 years since the first Numberphile video...
So we went back (with
@jamesgrime

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.

OK, I have a problem someone could probably simulate faster than I can work it out. I have a set of dice with values: 0, 0, 0, 0, 2, 3. You roll the dice, add up the total, then roll that number of dice. And repeat. If I start with five dice, how long will the game last?

Hi teachers. Do you know I go round and give maths talks that are really good? I do. Actually, Scotland, I've been asked to visit Aberdeen in March, so are there any schools or universities on my way who want to book at the same time? I'm trying to be efficient.

Here is what my notes look like for a video like this. This one largely went to plan, sometimes they don't!
Also, sometimes I make a note of a proof, with no intention of doing it in the video. Here's the proof about irreducible index, and why 18 is solitary.
