text: Economics is a messy discipline: too fluid to be a science, too rigorous to be an art. Perhaps it is fitting that economists’ most-used metric, gross domestic product (GDP), is a tangle too. GDP measures the total value of output in an economic territory. Its apparent simplicity explains why it is scrutinised down to tenths of a percentage point every month.

text: The insight underlying such wordlists is that frequency, combined with metrics such as range and dispersion, profiles for teachers and students the relative usefulness of words.

text: Ibanez had seen things with worse implications for herself, personally. That was the only metric of horror on which this sight knew remote equal. It was a wall, in a basic sense. It stretched from one side of the tunnel to the other, floor to ceiling, barring further passage. It was pink. It bubbled inside, and it sounded like a hundred simultaneous cases of indigestion which echoed off the rock around it.

glosses: A function which satisfies a particular set of formal conditions, created to generalize the notion of the distance between two points. Formally, a real-valued function d on M×M, where M is a set, is called a metric if (1) d(x,y)=0 if and only if x=y, (2) d(x,y)=d(y,x) for all pairs (x,y), and (3) d obeys the triangle inequality.
