I met a nice girl at a bar last night and asked her to call me when she made it home.
She must be homeless.

Henri DarcyDied 3 Jan 1858 at age 54 (born 10 Jun 1803).Henri-Philibert-Gaspard Darcy was a French hydraulic engineer who first derived the equation (now known as Darcy's law) that governs the laminar (nonturbulent) flow of fluids in homogeneous, porous media. In 1856, modern studies of groundwater began when Darcy was commissioned to develop a water-purification system for the city of Dijon, France. He constructed the first experimental apparatus to study the flow characteristics of water through the earth. From his experiments, he derived the Darcy's Law equation, describing the flow of water in nature, which is fundamental to understanding groundwater systems. He performed extensive tests on filtration and pipe resistance. He initiated the open-channel studies carried out by Bazin. |
