Because, of course, tomorrow is Mole Day. According to the National Mole Day Foundation:
Celebrated annually on October 23 from 6:02 a.m. to 6:02 p.m., Mole Day commemorates Avogadro's Number (6.02 x 10^23), which is a basic measuring unit in chemistry. Mole Day was created as a way to foster interest in chemistry. Schools throughout the United States and around the world celebrate Mole Day with various activities related to chemistry and/or moles.
Last year, I put up a post on Mole Day explaining the mole concept and why it matters in chemistry. But there was a little bit of grumbling that by posting it on Mole Day, I didn't give people fair warning ahead of time that there would be a reason to celebrate.
Please consider this your fair warning. Make proper arrangements for your mole sauce, your guacamole, your 6.02 x 1023 kernels of popcorn, or grains of rice, or champagne bubbles, or granules of Pixie Stix filling.
And while you're planning your Mole Day celebration, here's a festive Mole Day song for you to enjoy:
