Last year I replaced several windows in my house and they were the expensive double-pane energy efficient kind. But this week I got a call from the contractor complaining that his work has been completed for a whole year and I had yet to pay for them.
Boy oh boy did we go 'round. Just because I'm blonde doesn't mean that I am automatically stupid. So, I proceeded to tell him just what his fast talking sales guy had told me last year. . that in one year the windows would pay for themselves. There was silence on the other end of the line so I just hung up and I haven't heard back. Guess I must have won that silly argument.

Philipp Forchheimer

Born 7 Aug 1852; died 2 Oct 1933 at age 81.Austrian hydraulic engineer who made significant studies of groundwater hydrology. Early in his academic career, he worked on problems of soil mechanics. Later, he turned to hydraulic problems, establishing the scientific basis of the discipline by applying standard techniques of mathematical physics - in particular Laplace's equation - to problems of groundwater movement. Laplace's equation had already been well developed for heat flow and fluid flow. Forchheimer extended the preexisting mathematical theory to calculations of groundwater flow. He was also the first to both mathematically and experimentally examine the features of dambreak waves in a rectangular channel (with his PhD student Armin Schoklitsch).«
