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.

    Whir. Buzz.Not so long ago, math problems had to be solved with pencil and paper, mail delivered by postman, and files were stored in paper folders and metal cabinets. But three women, Betty Snyder, Jean Jennings, and Kay McNulty knew there could be a better way. During World War II, people hoped ENIAC (Electronic Numerical Integrator and Computer), one of the earliest computers, could help with the war effort. With little guidance, no instructions, and barely any access to the machine itself, Betty, Jean, and Kay used mathematics, electrical engineering, logic, and common sense to command a computer as large as a room and create the modern world. The machine was like Betty, requiring outside-the-box thinking, like Jean, persistent and consistent, and like Kay, no mistakes, every answer perfect. Today computers are all around us, performing every conceivable task, thanks, in large part, to Betty, Jean, and Kay's pioneering work. Instructions Not Included is their story.This fascinating chapter in history is brought to life with vivid prose by Tami Lewis Brown and Debbie Loren Dunn and with striking illustrations by Chelsea Beck.
