Every November 23rd, Fibonacci Day honors Leonardo Bonacci, one of the most influential mathematicians of the Middle Ages. The date corresponds to the first numbers of the Fibonacci sequence - 1 1 2 3.

Fibonacci is an Italian mathematician who is also known as Leonardo of Pisa and Leonardo Fibonacci. Some say Fibonacci invented the Fibonacci sequence. This pattern of counting means that each number is the sum of the previous two. (0,1,1,2,3,5,8,13, etc.) Computer data storage and processing uses this number sequence today. The sequence is also useful in the trading of stocks and architecture. Another unexpected place we find the sequence is in nature. DNA patterns and hurricanes contain patterns showing this sequence. Math and science classes refer to the Fibonacci sequence as “nature’s secret code” or “nature’s universal rule.” Additionally, the number sequence is tied to the golden ratio and the golden triangle.
