How mathematics shaped the design and value of our coins
In short: From Archimedes detecting fraud to the complex metallurgy of the Middle Ages, discover the mathematical principles that underpin the creation of currency and the logic behind decimal coinage.
Professor Sarah Hart explores the historical intersection of mathematics and money. The lecture examines how Archimedes developed methods to detect counterfeit gold, the significant mathematical challenges faced by Fibonacci and other medieval mathematicians when determining the correct metal proportions for coins, and the design logic behind denominations. Additionally, it investigates why the former Gresham Professor of Astronomy, Sir Christopher Wren, preferred a decimalised system for coinage.
