The interval [0,1] is uncountable, and there are many ways to prove that. Cantor's diagonal argument is a classic example. But there's another way: proof by playing a game. This video is an explanation of a proof by contradiction after assuming that the infinite set [0,1] is countable and playing a game on that interval. All we need is basic calculus for the limits of sequences!
