A Faithful Woman

An elderly Muslim lady was well-known for her faith and for her confidence in talking about it. She would stand in front of her house and say "Allah be praised" to all those who passed by.
Next door to her lived an atheist who would get so angry at her proclamations he would shout, "There ain't no Lord!!"
Hard times came upon the elderly lady, and she prayed for Allah to send her some assistance. She would pray out loud in her night prayer "Oh Allah! I need food!! I am having a hard time, please Lord, PLEASE LORD, SEND ME SOME GROCERIES!!"
One night the atheist happened to hear her as she was praying, and decided to play a prank on her. The next morning the lady went out on her porch and found a large bag of groceries. She raised her hands and shouted, "Allah be praised!."
The neighbor jumped from behind a bush and said, "Aha! I told you there was no Lord. I bought those groceries, God didn't."
The old lady laughed and clapped her hands and said, "ALLAH BE PRAISED. He not only sent me groceries, but he made the devil pay for them!"

Mole

In 1971, the mole—the amount of substance (matter)—was adopted as a chemical measurement added to the six base quantities of the SI (International System of scientific units). The decision was made by the Conférence Général des Poids et Mesures (CGPM), the principal executive organization under the Treaty of the Meter (which dates back to the Metric Convention on 20 May 1875). IUPAC's participation was led by M.L. McGlashan. The mole is the amount of substance of a system which contains as many elementary entities as there are carbon atoms in 0.012 kg of carbon 12. The elementary entities must be specified, such as atoms, molecules, ions, electrons, other particles, or specified groups of such particles. The agreed symbol for the unit is mol, and the symbol for amount of substance is n.«
