Sophie Kowalevski was both a brilliant mathematician and a talented writer. Creative work nurtured her mathematical research, giving her a flexibility of thought she treasured. A wonderful STEAM figure, she not only did mathematical research, but she also created many literary works. This inspiring title tells the story of Sophie’s journey as the first woman to receive a doctorate in mathematics, which required original research, holding a university chair in mathematics, and becoming the editor of a major scientific journal.


As many of you know, my first three books have been picture book biographies about (dead) women in STEM (science, technology, engineering, and math). You can tell by my next book’s title, Numbers in Motion: Sophie Kowalevski, Queen of Mathematics, that I’m sticking to tradition.

I write about women in STEM for two reasons. First, I have a passion for math and science. I want to show children how fun and exciting these fields can be. Second, it’s important to me that kids realize that anyone can grow up to be a scientist or mathematician (or technologist or engineer). All that matters is having an interest in those subjects—not sex, race, religion, country of origin, etc.

When I was a child, I was certain I’d be a mathematician when I grew up. Although my career took a different path (computer science), I never lost my love for math. Two of the women I’ve written about, Ada Lovelace and Grace Hopper, were mathematicians, but they’re more known for their contributions to computer science. I wanted to shine a spotlight on a woman whose life’s work was in mathematics.

But which one? So much of a mathematician’s work involves abstract thinking. It can be hard to explain these concepts to a grade school audience. Then I found Sophie Kowalevsi. Her major contribution to mathematics was the study the rotation of solid bodies, objects like planets and spinning tops. Kids could understand this mathematics. I found my mathematician.

My book found a home at Creston Books, the publisher that brought out my debut book, and I couldn’t be happier. After my editor, Marissa Moss, helped me polish the manuscript, she matched my words with an amazing illustrator, Yevgenia Nayberg.

Who knows? Maybe children will be inspired by Sophie’s story and find a career in mathematics.


Award-winning author Laurie Wallmark’s most recent book, a woman in STEM biography, NUMBERS IN MOTION: SOPHIE KOWALEVSKI, QUEEN OF MATHEMATICS (Creston Books), releases March 3, 2020. Her debut, ADA BYRON LOVELACE AND THE THINKING MACHINE (Creston Books, 2015), received four starred trade reviews (Kirkus, Publishers Weekly, Booklist, and School Library Journal) and many national awards including Outstanding Science Trade Book and Cook Prize Honor Book. Her picture book biography, GRACE HOPPER: QUEEN OF COMPUTER CODE (Sterling Children’s Books, 2017), earned a Kirkus star, is a Parents’ Choice Gold Medal winner, and is on several public libraries’ “best of” lists, including New York. Both of these books were Junior Library Guild selections. Her recently released book is HEDY LAMARR’S DOUBLE LIFE (Sterling Children’s Books, 2019) is a Cook Prize finalist, was long listed for the AAAS/Subaru SB&F Prize, and earned a Eureka! Gold Medal. She has an MFA in Writing for Children and Young Adults from Vermont College of Fine Arts. You can find Laurie on the Web at and @lauriewallmark.


Yevgenia Nayberg is an illustrator, painter, and set and costume designer. Her illustrations have appeared in magazines and picture books, and on theatre posters, music albums, and book covers; her paintings, drawings, and illustrations are held in private collections worldwide. As a set and costume designer, she has been the recipient of numerous awards, including the National Endowment for the Arts/TCG Fellowship for Theatre Designers, the Independent Theatre Award and the Arlin Meyer Award. In 2018 she received a Sydney Taylor Silver Medal for her illustrations for Drop by Drop by Jaqueline Jules. Her debut author/illustrator picture book, Anya’s Secret Society, came out in 2019 and received a Junior Library Guild Selection Award.

Yevgenia Nayberg was born in Kiev, Ukraine. After graduating from The National School of Art in Kiev, she began working as a freelance illustrator and an assistant art director for, UkranimaFilm, an animation studio. Yevgenia moved to the United States in 1994, where she studied theatre design at Carnegie Mellon University. At the age of 23 she received her MFA degree in Theatre design from California State University, Long Beach. She has since enjoyed a successful career as a painter, scenic – costume designer, and illustrator. Yevgenia’s dedication to theatrical arts is clearly manifested in her illustrations which rely on color intensity, fantastic landscapes, and dramatic light and shadow to tell a story. When illustrating, she likes to look for a visual equivalent of a word, for metaphorical translation into the language of visual art.

Her new books, Typewriter and Mona Lisa in New York, will be published in 2020. She lives in New York City.

Laurie thank you for sharing your journey and book with us. Yevgenia has done a fabulous job bring the book to life. Winner is written all over this book. Good luck! 

Talk tomorrow,



  1. Hallo, Hallo Kathy,

    What a beautiful celebration of Math! I never fully understood mathematics growing up but I have held onto my fascination with Science and continue to pursue it as a reader – reading hearty topics in STEM and other branches of Science. The illustrations are lushly depicting a certain respect for science and math whilst the colour palette is incredible! I had hoped to pursue a science degree at university but there were reasons why I recognised Uni wasn’t a good fit for me; sadly, I wish there were more alternative ways of gaining more knowledge than traditional outlets for those of us who remain curiously attune to certain branches of literature, science and history.

    I love finding new routes towards becoming introduced to Biographies of #WomenInScience and this is just an incredible book!

    I will definiltely be sharing this on Twitter!

    Thanks for the chance to win such a beautifully inspiring book! I definitely want to start collecting this whole series – truly a remarkable find and I serendiptiously found you this morning via Reader on WP!

  16. I hope this beautiful book wins some awards. I’ve already shared the link to this post with a friend whose daughter and son-in-law are PhD mathematicians; I am sure they will be sharing this story with their little girls!
    Congrats on having this book published, and having it so lavishly and evocatively illustrated!


  17. A wonderful marriage of art, text, and subject. Congrats!

  18. This book looks magical. Please add my name for consideration. I love Women in STEM/STEAM books! If I had had these kind of books when I was in elementary school, I might have pursued a scientific career. It probably would’ve still included music somehow, lol.😆 Congrats to all involved in this book.✌🏼🎶🎨📚😊


  19. Forgot to mention, I am also signed up for your blog Kathy, and I RT’d this and commented. Already following Laurie.


  20. Laurie, Looking forward to reading your next book about another dead woman in STEM! 🙂


  21. Laurie- I love your work and your efforts to bring STEM and pioneering women to the forefront. Need to add this new one to my collection!


  22. Congratulations, Laurie, on your latest #PB #Biography. I’ve loved your other books, and can’t wait to learn about Sophie. Seems to be great pairing with Nayberg’s art, too. These spreads make me want to see more!


  23. Can’t wait to check it out!


  24. Not sure if it is still ok to throw my name in for prize consideration, but I am flinging it in heartily. THis looks amazing, and I am so glad to see another Women in STEM book. Would love to read this and then display with my copy of Grace Hopper in the Kidlit Recording Studio. Congratulations to all involved with this welcome and needed book.


  25. Love Laurie’s nonfiction!
