Hey, it's National Chemistry Week (and it has been since yesterday). Also, from 6:02 AM until 6:02 PM today, it was Mole Day.
I had hoped to have lots of time to wallow in the festivities, crack Mole Day jokes, and so on, but as it turns out I have 6.02 x 10^23 things on my to-do list today, so y'all will have to celebrate without me.
