History of Sônia Caetano - Rio Grande do Norte, Brasil
November 23rd Fibonacci Day. The date was chosen because, when referring to the Fibonacci sequence, which is a numerical series in which each number is the sum of the two previous ones (0, 1, 1, 2, 3, 5, 8, 13, 21, etc.), the sequence can be represented by the pair of numbers (1, 1) on November 23rd, if we consider the numbers 23 and 11. The origin of the celebration goes back to the Italian mathematician Leonardo de Pisa, known as Fibonacci, who lived in the 13th century. He is famous for having introduced the Fibonacci sequence to the Western world through his book Liber Abaci, published in 1202. The sequence not only appears in various areas of mathematics, but also manifests itself in natural patterns, such as the arrangement of leaves on a plant, the reproduction of rabbits and the structures of flowers.
