Today is Fibonacci Day! Celebrated on November 23rd, the date corresponds with the first four numbers of the Fibonacci Sequence (1,1,2,3). We love how the numbers of this famous pattern sometimes manifest in nature. Mesmerizing, right? Try to imagine a day without numbers. Never mind a day, try to imagine getting through the first hour without numbers: no alarm clock, no time, no date, no TV or radio, no stock market report or sports results in the newspapers, no bank account to check. It's not clear exactly where you are waking up either, for without numbers modern housing would not exist. A young Italian man, Leonardo of Pisa — the man who many centuries later a historian would dub "Fibonacci" — completed the first general purpose arithmetic book in the West, Liber abbaci, that explained the "new" methods in terms that ordinary people could understand — tradesmen and businessmen as well as schoolchildren. While other lineages can be traced, Leonardo's influence, through Liber abbaci, was by far the most significant and shaped the development of modern western Europe.

Look for Circles Day is for looking up, down, and every which way in order to identify and point out objects shaped like circles. The day isn't limited to children, however; anyone can look for and point out circles. Circles can be found inside homes, at places of employment, on the street, in nature, and elsewhere. Look in your home, look in nature, look while walking down the street, and look wherever you go. You could challenge a friend or a group of friends to a contest to see who can find the most circles. You could look for circles in math.
