Welcome to my channel - Eternity in an Hour where I play around with maths, computers, puzzles, games and ideas. I think a lot of people haven't seen how beautiful, fascinating and human mathematics and science can be. This is a channel to share mathematics, science, programming and STEM knowledge, and I often publish a mixture of my own problems and solutions to others'.
