AMEN, BROTHER!

Two elderly, excited women were sitting together in the front pew of church listening to a fiery preacher. When this preacher condemned the sin of lust, these two ladies cried out at the tops of their lungs..."AMEN, BROTHER!"

When the preacher condemned the sin of stealing, they yelled again..."PREACH IT, REVEREND!"

And when the preacher condemned the sin of lying...they jumped to their feet and screamed, "RIGHT ON, BROTHER...TELL IT LIKE IT IS...AMEN!"

But when the preacher condemned the sin of gossip, the two got very quiet, and one turned to the other and said, "He's done quit preaching and now he's meddlin'."

Count of Quaregna Amedeo Avogadro

Born 9 Aug 1776; died 9 Jul 1856 at age 79. 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.)«
