Numbers in Motion by Laurie Wallmark

Let’s explore a new picture book biography, Numbers in Motion: Sophie Kowalevski, Queen of Mathematics by Laurie Wallmark and illustrated by Yevgenia Nayberg.

Laurie Wallmark specializes in biographies of women in STEM and for this book she has chosen a lesser-known subject for much-deserved recognition.

Sophie Kowalevski grew up observing the pages of calculus problems her father had used to paper her bedroom walls. The desire to understand the intriguing symbols propelled her to study advanced math. Later she became a prominent mathematician — the first to earn a doctorate at an European university — and professor in a time when women weren’t even allowed to enter many college campuses. By doing what she loved and had a talent for, Sophie broke down barriers for women who came after her.

Illustrator Yevgenia Nayberg uses a light touch with Sophie’s life, then makes Sophie’s math vibrant. In one scene the tops look like they are going to spin right out of the book. Her approach makes sense because those were the things Sophie cared the most about.

Numbers in Motion will inspire budding mathematicians and historians alike. Readers will likely end up wanting to learn more about this remarkable woman. Investigate a copy today.
