  As for the large number of official statements that Spain is safe, I think they are merely a metric of the complacency that has characterised the European crisis from the start.

  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. (mathematics) A function for the measurement of the "distance" between two points in some metric space: it is a real-valued function d(x,y) between points x and y satisfying the following properties: (1) "non-negativity": d ( x , y ) ≥ 0 , (2) "identity of indiscernibles": d ( x , y ) = 0 iff x = y , (3) "symmetry": d ( x , y ) = d ( y , x ) , and (4) "triangle inequality": d ( x , y ) ≤ d ( x , z ) + d ( z , y ) .
