Canning Day
(Too late .. hubby already disced garden area)




Mole Day

Celebrated annually on October 23 from 6:02 a.m. to 6:02 p.m.,
Mole Day commemorates Avogadro's Number (6.02 x 10^23),
which is a basic measuring unit in chemistry.
Mole Day was created as a way to foster interest in chemistry.
Schools throughout the United States and around the world celebrate Mole Day
with various activities related to chemistry and/or moles.

I know, I know. It's baaaaaaad. I just couldn't help it. LOL!

Happy Mole Day!

Mole Day

UH...add orange stuff to blue stuff and he’s happy because it blew up? I have no clue, but it’s funny!

Canning day—I did my part this year. Trust me, whatever a can of tomatoes costs at the store, it’s worth it! LOL

Choric Song From “The Lotus Eaters”

There is sweet music here that softer falls
Than petals from blown roses on the grass,
Or night-dews on still waters between walls
Of shadowy granite, in a gleaming pass;
Music that gentlier on the spirit lies,
Than tired eyelids upon tired eyes;
Music that brings sweet sleep down from the blissful skies.
Here are cool mosses deep,
And through the moss the ivies creep,
And in the stream the long-leaved flowers weep,
And from the craggy ledge the poppy hangs in sleep.

Alfred, Lord Tenyson

Well, it's both simple, and complicated.

In 1811, Avogadro published an article in Journal de physique that clearly drew the distinction between the molecule and the atom. He pointed out that Dalton had confused the concepts of atoms and molecules. The "atoms" of nitrogen and oxygen are in reality "molecules" containing two atoms each. Thus two molecules of hydrogen can combine with one molecule of oxygen to produce two molecules of water.

Avogadro suggested that:

equal volumes of all gases at the same temperature and pressure contain the same number of molecules

which is now known as Avogadro's Principle.

It was this concept that allowed researchers to begin dealing with large numbers of atoms, (a necessity in any case), and yet have a clear understanding of how the individual atoms were reacting.

Initially, they weren't entirely sure whether they were dealing with atoms or molecules, but thanks to Avogadro, they knew how many were involved in a particular volume. It was for this reason that the term "mole" became popular. It is a term that denotes a particular number of things. It's more than a dozen, and it's more than a trillion, or even a decillion, but it sounds friendlier.

This led to a clearer understanding of Atomic Number, Atomic Weight, and eventually developed into a recognition that there were isotopes.

All of this was necessary as a precursor to understanding how the Sun got its energy. One can make a back-of-the-envelope calculation of how much energy the Sun sends out to this distance; the radius of Earth's orbit. Since the Sun sends this energy in all directions, the numbers grow enormous. What could possibly provide so much energy?

So, in essence, Avogadro and his "moles" did the spadework for another peculiar fellow named Albert Einstein.
