It’s National Mole Day

I may not remember every lecture that Mr. Lieber ever gave, but I don’t think anything could ever erase the memory of my 10th grade chemistry teacher dancing around the front of the classroom in a frenetic “Mole Day Dance.”

What’s Mole Day? Every October 23rd, we celebrate the “mole.” Not the furry creature, but the term an Italian scientist named Amedeo Avogadro coined in 1811. The mole, sometimes called Avogadro’s Number, is a unit of measurement used in chemistry.

We hope you enjoy this selection of mole jokes. It’s brightened our day, and kept (most of us) from breaking out in embarassing dances.
