The fabric of the universe via backwards Bach.
If mathemusician Vi Hart — who for the past three years has been bringing whimsy to math with her mind-bending, playful, and illuminating stop-motion musical doodles — isn’t already your hero, she should be, and likely will be. (Cue in the GRAMMYs newly announced search for great music teachers.) In her latest gem, Hart uses music notation, a Möbius strip, and backwards Bach to explain space-time:
Music has two recognizable dimensions — one is time, and the other is pitch-space. … There [are] a few things to notice about written music: Firstly, that it is not music — you can’t listen to this. … It’s not music — it’s music notation, and you can only interpret it into the beautiful music it represents.
