Happy Avogadro's Day! Amedeo Avogadro theorized that equal volumes of all gases at the same temperature and pressure contain the same number of molecules. His law enabled the calculation of the number of molecules in a cubic centimeter of gas: 6.02214199 × 1023, which is known as Avogadro's Number; it also led to the definition of the commonly used mole unit. So why is today Avogadro's Day? It's 10-23. Go kiss a physicist.
