## epsilon squared

**epsilon squared** /n./ A quantity even smaller than
epsilon, as small in comparison to epsilon as epsilon is to
something normal; completely negligible. If you buy a
supercomputer for a million dollars, the cost of the
thousand-dollar terminal to go with it is epsilon, and the
cost of the ten-dollar cable to connect them is epsilon squared.
Compare lost in the underflow, lost in the noise.
