Tonight's Sky for October 23: Mole Day

Today is Mole Day. Why? Because today is 10-23, which is the latter half of the equation of 6.02x1023, which is the latter half of the equation representing Avogadro's Number, which in itself represent the number of atoms in 1 Mole (Mol) of any given substance Why the fascination with the Mole for chemists? One mole of any substance contains Avogadro's Number of molecules or atoms of that substance, making the Mole a handy unit of measure to uses when doing chemical calculations. This fact was discovered by Amadeo Avogadro (1776-1858). While started by chemists, Mole Day is now commonly celebrated by science enthusiasts in general.

Mole Day Joke:

Mama mole squeezes out of the hole next to Papa. What does she smell? Nothing.
Junior mole tries to stick his head out but can't get out. What does he smell? Molasses.
