Leonardo of Pisa (Fibonacci)

Leonardo of Pisa, known as Fibonacci, was a medieval Italian mathematician who introduced the Western world to the Hindu-Arabic number system. He is famous for the Fibonacci sequence, a series where each number is the sum of the two preceding ones (0, 1, 1, 2, 3, 5, 8...). This sequence appears in nature, art, and mathematics, illustrating growth patterns and proportions. Fibonacci's work helped popularize the use of decimal numbers and advanced mathematical understanding, influencing fields such as computer science, finance, and biology. His contributions bridge ancient mathematics and modern science, shaping how we understand patterns and structure.
