Interesting problem how to arrange marching bands (we see an amazing sequence) leads to exploration of square numbers, square root of two, proof by contradiction and the irrationality of the square root of two. Some good discussion relating to rational approximations of pi - find a version for square root of two. New YouTube math channel: Mathologer
