“It is possible to commit no mistakes and still lose. That is not a weakness. That is life.” -Jean-Luc Picard
We like to think of nature as beautiful, elegant and infallible. Yet our notions of what's beautiful and elegant don't always line up with what reality gives us. Take the notion of symmetry, for example: the gravitational force is symmetric, always exerting equal magnitude forces on whatever two masses it occurs between.
