Also known as the time.
Today, I was forwarded a copy of a specification that would allow to human race to break free so that, "no longer would such unscientific terms like the 'sun rise' and 'sun set' rule the human race! No, they could now use high class terms like 'angles' and 'degrees' and, dare they even suggest it, 'radians'."
