Sophie's Diary, book by Dora Musielak

This book was inspired by the life of French mathematician Sophie Germain.

Sophie Germain made important contributions to number theory and mathematical physics. She advanced the proof to Fermat's Last Theorem, a proof so challenging that it took many mathematicians' efforts and more than 300  years to complete.

History records the achievements of other great female mathematicians who lived before and accomplished as much, but Sophie Germain did it alone. Hypathia had her father, Theon of Alexandria to teach her; Maria Agnessi had her Rampinelli and other instructors; and Emilie Chatelet had Maupertuis and Clairaut as her tutors of mathematics. Sophie Germain had no teacher.

Starting with the scant biographical information available about Germain’s adolescence, Dora Musielak began to piece together a story of a young Parisian girl who discovers mathematics at the beginning of 1789, a time that coincides with the start of the bloody French Revolution. Armed with her own experience and love for mathematics, Dora Musielak develops a fictional character inspired by Sophie Germain. Using the format of a personal diary Musielak writes how the shy 13-year-old girl, who has been taught basic arithmetic by her father, begins to read about the ancient scholars and becomes fascinated by mathematics. Without a tutor to guide her Sophie reads everything relevant in her father’s library, and the more she reads the more she wants to learn mathematics. As the French Revolution builds up she begins to master algebra and arithmetic, and her hunger for knowledge intensifies.  

 

Dora Musielak’s account sets in perspective the challenges of learning alone. Her fictional character Sophie, although timid and soft-spoken, is resourceful and develops the courage to approach those who might provide her with the tools to learn more.
