In one of the episodes, Andrea Busque lends her voice to Élie Olivennes's words to tell us about that evening of 5 June 1833 when the British mathematician Charles Babbage (1791–1871) presented his first Difference Engine in London's fashionable districts. Its creator was enthusiastic about its mechanisms, capable of calculating polynomial functions, but the audience was somewhat disappointed. Only one person truly grasped the machine's potential: Augusta Ada Byron (1815–1852), a 17-year-old woman and daughter of the celebrated poet Lord Byron. This was the beginning of a collaboration that would lay the foundations of modern computing.
What follows is a more straightforward biography of our heroine. Once she reaches adulthood, household duties curb her mathematical drive. But Babbage embarks on designing an Analytical Engine, a “steam computer”! This piques Ada Lovelace's curiosity, and every evening she becomes absorbed in the intellectual exploration of this new machine. It is in this context that she writes what is now considered the first computer program in history!
Two other episodes are devoted to Florence Nightingale (1820–1910) and Alan Mathison Turing (1912–1954).
