an interesting article about the development of penicillin.
in other news, i am digging out my basement and discovered my old chemistry notes. as i was looking over them fondly, i realized that i don't understand them anymore. sheesh. i think i might have to take a chemistry class to brush up again. if you don't use it, you lose it. on a related note, i am thinking about taking a dance class again. even making my husband take a ballroom dance class. fun!
