Sophie Germain grew up France at a time of chaos during the French Revolution. She found order in math. Nothing could detract from her interest, despite mathematics being considered unsuitable for a girl. Sophie thought math was like a poem, and she wanted to write poetry of her own. No university would let her enroll as a woman, so she submitted work under a man’s name. When her identity was finally discovered, she was considered more curiosity than scholar. For years, she studied on her own, eventually solving a problem many considered unsolvable: develop a mathematical formula to predict patterns of vibration. This picture-book account of Sophie’s accomplishment is followed by more about Sophie and her work, including the relationship between math and physics, as well as informative notes from both author and illustrator on their research and approach to this treatment, including how they conjectured about what isn’t known. (Ages 6–9)

The true story of eighteenth-century mathematician Sophie Germain, who solved the unsolvable to achieve her dream.

When her parents took away her candles to keep their young daughter from studying math...nothing stopped Sophie. When a professor discovered that the homework sent to him under a male pen name came from a woman...nothing stopped Sophie. And when she tackled a math problem that male scholars said would be impossible to solve...still, nothing stopped Sophie.

For six years Sophie Germain used her love of math and her undeniable determination to test equations that would predict patterns of vibrations. She eventually became the first woman to win a grand prize from France's prestigious Academy of Sciences for her formula, which laid the groundwork for much of modern architecture (and can be seen in the book's illustrations).

Award-winning author Cheryl Bardoe's inspiring and poetic text is brought to life by acclaimed artist Barbara McClintock's intricate pen-and-ink, watercolor, and collage illustrations in this true story about a woman who let nothing stop her.
