In Chemistry, molecules and atoms are often measured in a unit called a mole. One mole of something is 6.022 x 10^23 molecules of that something. In other words....

1 mole of Carbon = 6.022 x 10^23 atoms of Carbon

This "6.022 x 10^23" is known as Avogadro's Number.

Today is the lovely, yet nerdy holiday known as "Mole Day". October 23rd... from the 10^23 part of Avogadro's Number.

So I would like to wish everyone a HAPPY MOLE DAY!
