The Secret Formula

Meer over het boek

The story follows two Renaissance mathematicians whose rivalries and debates led to the discovery of a formula for solving the cubic equation. Niccolò Tartaglia, an ambitious teacher, held a secret formula that could solve a long-standing mathematical problem, which he cleverly disguised in a poem to protect it from theft. In contrast, Gerolamo Cardano, a physician and cunning scholar, was determined to uncover Tartaglia's secret, employing flattery and trickery to achieve his goal. Set in sixteenth-century Italy, the narrative offers intriguing insights into the era's mathematics and culture, where intellectual duels captivated audiences and brought fame and fortune to the victors. After Tartaglia's impressive win in a public contest in Venice, Cardano invited him to Milan, intent on learning the coveted formula. Cardano's efforts culminated in 1545 when he became the first to publish a general solution for the cubic equation. In response, Tartaglia sought to reclaim his reputation by challenging Cardano to a mathematical duel. This engaging account of ambition, betrayal, and human flaws unveils the fierce rivalry that shaped a pivotal concept in modern algebra.
