The preacher's Sunday sermon...

The preacher's Sunday sermon was "Forgive Your Enemies." He asked how many of the congregation have forgiven their enemies? About half held up their hands. He then repeated his question. Now about 80 % held up their hands. He then repeated his question once more. All responded, except one elderly lady.
"Mrs. Johnson, are you not willing to forgive your enemies?"
"I don't have any."
"Mrs. Johnson that is very unusual. How old are you?"
"Ninety-three," she replied.
"Mrs. Johnson, please come down in front and tell the congregation how a person cannot have an enemy in the world?"
The little sweetheart of a lady tottered down the aisle and said, "I outlived every one of those bitches!"

Jean Perrin

Died 17 Apr 1942 at age 71 (born 30 Sep 1870). Jean-Baptiste Perrin was a French physicist who, in his studies of the Brownian motion of minute particles suspended in liquids, verified Albert Einstein's explanation of this phenomenon and thereby confirmed the atomic nature of matter. Using a gamboge emulsion, Perrin was able to determine by a new method, one of the most important physical constants, Avogadro's number (the number of molecules of a substance in so many grams as indicated by the molecular weight, for example, the number of molecules in two grams of hydrogen). The value obtained corresponded, within the limits of error, to that given by the kinetic theory of gases. For this achievement he was honoured with the Nobel Prize for Physics in 1926.
