Cheerleaders Vs. St. Peter

A high school cheerleading squad were in a bus that shot off a cliff killing all onboard... Don't laugh yet! 
When they got to heaven they were met by St. Peter at the gate.
He asked the first girl if she had done anything with any boys, and she said to St. Peter that she had held a boys hand, so St. Peter told her to wash her hands in the holy water before entering heaven. 
St. Peter then asked the second girl the same question, and she said she had kissed a boy, so Peter told her to wash her lips in holy water before entering heaven. 
Then Peter noticed two farther back in line girls arguing over their position in line. 
Peter asked the girls what was going on, and the one girl said to him, "I'm not gargling that after she sits in it."

Joseph Loschmidt

Born 15 May 1821; died 8 Jul 1895 at age 74. Johann Joseph Loschmidt was an Austrian chemist and physicist who was thefirsttopropose(1861) some kind of cyclic structure for benzene and many aromatic hydrocarbons. (Four years later, Kekulé devised the correct ring structure, for which his name is remembered while Loschmidt's contribution is overlooked.) He deduced the size of air molecules to be around one nanometer, with two approaches: relating the size of gas molecules to the distance travelled between collisions, and considering the packed volume of molecules in a cold liquid. Completing Avogadro's insight that all gases have the same number of molecules in a given volume, Loschmidt measured Avogadro's constant to be 6.03 x 1023 molecules in one mole of a gas (1865).«
