Bob was in trouble. He forgot...

Bob was in trouble. He forgot his wedding anniversary. His wife was really angry. She told him "Tomorrow morning, I expect to find a gift in the driveway that goes from 0 to 200 in 6 seconds AND IT BETTER BE THERE!" The next morning he got up early and left for work. When his wife woke up, she looked out the window and sure enough there was a box gift-wrapped in the middle of the driveway. Confused, the wife put on her robe and ran out to the driveway, brought the box back in the house. She opened it and found a brand new bathroom scale. Bob has been missing since Friday.

Jacobus Henricus Van't Hoff

Born 30 Aug 1852; died 1 Mar 1911 at age 58. Dutch physical chemist who was the first winner of the Nobel Prize for Chemistry (1901) “in recognition of the extraordinary services he has rendered by the discovery of the laws of chemical dynamics and osmotic pressure in solutions.” In stereochemistry, in 1874, he identified the four chemical bonds of carbon as having a tetrahedral arrangement, which explained how certain moleculars can be arranged differently with the same atoms to give left- and right-handed isomers. (Achille Bel arrived independently at the same conclusion at about the same time.) With regard to the osmotic pressure of liquids, he derived laws (1886) for dilute solutions similar to the gas laws for gases by Robert Boyle and Joseph Gay-Lussac. These relationships enabled the experimental determination of the molecular weight of a substance in solution.«
