Today it is my pleasure to feature Award-winning PB author LAURIE WALLMARK with her new non-fiction STEM picture book titled NUMBERS IN MOTION: SOPHIE KOWALEVSKI, QUEEN OF MATHEMATICS (Creston).

1. Sophie solved a problem known as the mathematical mermaid. Just when people were  close to figuring out the solution, it seemed to slip away from them like the mythical mermaid.

2. Sophie was the first woman to receive a doctorate in mathematics that required doing original research.

3. Sophie was the first woman to hold a university chair in mathematics.

1. I was amazed that in the late 1800s, a woman couldn’t leave Russia except in the company of her husband or father.

2. I was amazed that until Sophie, there hadn’t been any woman professional mathematicians since Hypatia in fifth century Egypt.

3. I was amazed to find that the mathematical methods that Sophie discovered have increasing application to physics today.

I’ve had an opportunity to read this fascinating book and here’s my review:

“NUMBERS IN MOTION: SOPHIE KOWALEVSKI, QUEEN OF MATHEMATICS  by Laurie Wallmark (CRESTON)  is an inspiring look at a pioneering woman who never took “no” as the final answer.  Written in a clear and engaging manner, the positive messages of never giving up and having faith in your own abilities are great lessons for the classroom and beyond.” 5 stars.
