Fibonacci

Leonardo of Pisa, commonly known as Fibonacci, was a medieval Italian mathematician renowned for introducing the Hindu-Arabic numeral system to Europe, revolutionizing mathematical computation. His most famous work, "Liber Abaci" (The Book of Calculation), popularized the use of Arabic numerals and the decimal system, significantly simplifying arithmetic and algebraic calculations. Fibonacci is best known for his sequence, where each number is the sum of the two preceding ones (0, 1, 1, 2, 3, 5, 8, 13, ...). This sequence has profound applications in various fields, including mathematics, biology, art, and finance, reflecting the inherent patterns found in nature and the universe. Fibonacci's contributions laid the foundation for modern mathematics and continue to influence diverse disciplines, making him one of the most significant mathematicians in history.
