| Sophie's Diary, book by Dora Musielak |  |
This book was inspired by the 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.
Sophie's Diary is available from AuthorHouse, amazon.com, Barnes & Noble, and many other booksellers.
