Chemists celebrate Mole Day from 6:02am to 6:02pm on 10/23! The American Chemical Society (ACS) always organizes National Chemistry Week in the week that includes 10/23 to honor Mole Day, and you can learn all about the holiday at the National Mole Day Foundation website. To recognize the holiday, please help yourself to mole-themed cookies in the Mohrig Lounge (second floor of Anderson).
