From 6:02 am to 6:02 pm, today is National Mole Day.
No, not “moles” like the cute little blind animals that dig up your yard … this is a day for chemistry geeks to celebrate Avogadro’s number, a basic unit of measurement that equals the weight of a single atom, measured in grams, which is 6.02 x 10^23. Hence celebrating on 10/23 at 6:02. Whatever … it’s still National Mole Day, so you can choose whether to wear a Mole Day shirt for chemistry geeks or some of the cute little animal moles here!
