Happy Mole Day!
Today is a special holiday—Mole Day. Mole Day is an informal holiday that originated among North American chemists, chemistry students, and chemistry enthusiasts. People celebrate this chemistry-specific festival between 6:02 AM and 6:02 PM on October 23rd. A mole is a common unit in chemistry, and one mole of a substance contains several basic particles equal to Avogadro's number. In the American date format, the celebration time of Mole Day is written as 6:02 10/23, which looks very similar to Avogadro's number 6.02×10²³, hence the birth of this holiday. Moreover, the word "mole" in English also refers to a "mole (animal)", so the mole is used as the mascot of the holiday. Many high schools in the United States, South Africa, Australia, Canada, and other places celebrate Mole Day, where various activities related to chemistry or moles are held to stimulate students' interest in chemistry.
