Celebrate National Mole Day!
Today, October 23, is National Mole Day from 6:02 a.m. to 6.02 p.m. "Molar Express" is the theme for 2009. The "mole" is a way of counting the Avogadro number which is 6.02x10 to the 23rd power of anything. Amedeo Avogadro was a 19th century phycisist who discovered that the number of molecules in a mole is the same for all substances. This information is incredibly helpful to chemists who measure quantities of chemicals in their labs. Mole Day is celebrated to get students enthused about chemistry. The above website provides all kinds of nifty ideas on how to celebrate.
So impress your friends with this new bit of knowledge if you haven't heard of it already and....start counting! (I knew those moles were good for something besides tearing up the garden).
