Outdone

A strong young man at the construction site was bragging that he could outdo anyone in a feat of strength. He made a special case of making fun of Morris, one of the older workers.

After several minutes, Morris had had enough. "Why don't you put your money where your mouth is?" he said: "I will bet a week's wages that I can haul something in a wheelbarrow over to that outbuilding that you won't be able to wheel back."

"You're on, old man," the braggart replied: "It's a bet! Let's see what you got."

Morris reached out and grabbed the wheelbarrow by the handles. Then, nodding to the young man, he said, "All right. Get in."

Count of Quaregna Amedeo Avogadro

Died 9 Jul 1856 at age 79 (born 9 Aug 1776). Italian chemist and physicist who found that at the same temperature and pressure equal volumes of all perfect gases contain the same number of particles, known as Avogadro's Law (1811) leading to the Avogadro's constant being 6.022 x 1023 units per mole of a substance. He realized the particules could be either atoms, or more often, combinations of atoms, for which he coined the word "molecule." This explained Gay-Lussac's law of combining volumes (1809). Further, Avogadro determined from the electrolysis of water that it contained molecules formed from two hydrogen atoms for each atom of oxygen, by which the individual oxygen atom was 16 times heavier than one hydrogen atom (not 8 times as suggested earlier by John Dalton.)«
