If you are fond of classical music, then you have probably heard of Johann Sebastian Bach. He was one of the great composers of the Baroque period. His music was known for its intellectual depth, technical command, and artistic beauty (I copied the last sentence from Wikipedia, lol).
But what will surprise you more is how his music is tied to mathematics. Watch the video below of how playing the music backwards and forwards simultaneously can be visualized using a Moebius Strip.
