Today is October 23, which in the U.S. is written as 10/23. That means it’s Mole Day!

For the non-geeky non-sciencey types out there, a mole is a number used in chemistry quite a bit. It’s used to measures the number of atoms or molecules in a sample, and it equals 6.02 x 1023 — a pretty hefty number. Note the exponent; that’s where today’s date comes in (Mole Day is celebrated from 6:02 a.m. to 6:02 p.m., by the way). I’m a number nerd, so I love this stuff. If you’ll indulge me, I’ll be happy to explain.

I taught my nephew avagadro's number when he was just learning to talk. I drilled him on it so that when ever asked, he would know. It was a fun parlor trick and served him well into his later years.

@tsarstepan,
Got any idea how long it took Mrs. Avagadro to count them?
