National Chemistry Week

 
This is National Chemistry Week in the United States of America. Janet Stemwedel reminded us [Holy mole-y, it’s National Chemistry Week!]. She's a chemist AND a philosopher!¹

I like chemistry because it helps us understand really important things like biology. Here's the biochemistry version of the Periodic Table of the Elements. It shows you which ones you can ignore!
