The Man of Numbers

In 1202, Italian mathematician Leonardo of Pisa, known as Fibonacci, published "Liber abbaci," a groundbreaking work that introduced the Hindu-Arabic numeral system to Western Europe. This revolutionary book facilitated modern arithmetic, enhancing commerce and record-keeping and ultimately laying the groundwork for the scientific revolution of the Renaissance. Despite his influential contributions, Fibonacci remains an enigmatic figure, with his name most recognized for the Fibonacci sequence, which appears in various natural structures and is sometimes linked to financial predictions. Keith Devlin explores Fibonacci’s life and legacy, highlighting the crucial role of numbers and mathematics in our everyday experiences.
