Mole Day today!

I just found out that today is Mole Day, which, according to the Wikipedia, is "celebrated among chemists on October 23, between 6:02 AM and 6:02 PM,^[1][2][3] making the date 6:02 10/23 in the American style of writing dates. The time and date are derived from Avogadro's number, which is approximately 6.02×10²³, defining the number of particles (atoms or molecules) in one mole of substance . . ."

In other words, strictly a holiday for nerds, and has nothing to do with the mammal that lives mostly underground, including under the surface of our lawn, at times, except that it's OK to use mole, in any sense, in puns.

Here's a web page on the history of National Mole Day.

There's a National Mole Day Foundation. You can join it, by paying moledues.

There's at least one page of Mole Day jokes. Sample: "molearchy - government in which moles are in complete control; under this government Mole Day is celebrated three times a year and chemistry is the only scientific subject taught in school"

Happy Mole Day!
