National Mole Day

Today, from 6:02 a.m. to 6:02 p.m. on 10.23, is a celebration of Avogadro’s number (6.02 x 10^23). Avogadro discovered a number that facilitated balancing chemical formulas on the molecular level (and thus the name “mole”). This revolutionized chemical research. If Avagadro’s number was converted into dollars, and you spent one billion dollars a second, it would take you more than 19 million years to spend it.

What’s better than noting a landmark of science? Making really bad jokes about it. Here’s a few straight from the awesome National Mole Day website:

What do you get when you have a lot of moles acting like idiots? A bunch of moleasses.


If Avogadro were to watch M*A*S*H, who would be his favorite character? Father Molecahy.

Visit the site for some great Mole Day project ideas, or since Halloween’s just around the corner, put together a mole costume and completely befuddle your neighbors.
