October 23 is Mole Day in the science world. You can read about Mole Day on this website. Or you can look up activities and crafts suggested by the ACS (American Chemical Society) For non-science people, it just a general awareness day based on a scientific constant that anyone that has taken chemistry has used before, Avogadro’s Number (6.02 x 10^23). I may look to see if I can make something today (food wise) to celebrate. Mole Day always sneaks up on me.
