   • 2013 August 3, “Boundary problems”, in The Economist, volume 408, number 8847:

     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.

2. Severe; intense.

   a rigorous winter.
