Henrietta spent years measuring star positions and sizes from photographs taken by the telescope at the Harvard College Observatory, where she worked. After Henrietta observed that certain stars had a fixed pattern to their changes, her discovery made it possible for astronomers to measure greater and greater distances—leading to our present understanding of the vast size of the universe.An astronomer of her time called Henrietta Leavitt “one of the most important women ever to touch astronomy,” and another close associate said she had the “best mind at the Harvard Observatory.” Henrietta Leaveitt's story will inspire young women and aspiring scientists of all kinds and includes additional information about the solar system and astronomy.

    Although she might look like an ordinary little girl, she’s about to change the world.Augusta Ada Byron, better known as Ada Lovelace, is an inquisitive child. Like her clever mother, she loves solving problems—big problems, little problems, and tricky, complicated problems. Ada invents crazy contraptions and reads all the books in the library of her father, the poet Lord Byron; but most of all she loves to solve mathematical problems. Together with her teacher, the mathematician Charles Babbage, Ada invents the world’s first computer program. Her achievements made her a pioneer for women in the sciences. Zoë Tucker’s words capture the adventurous life of Ada succinctly, and debut picture book illustrator Rachel Katstaller’s art infuses Victorian London with humor.

    He gave her a scientific education, which was highly unusual for women and girls in the early 19th century. Fascinated with the plant life around her, Anna became a botanist. She recorded all her findings in detailed illustrations and engravings, until the invention of cyanotype photography in 1842. Anna used this new technology in order to catalogue plant specimens—a true marriage of science and art. In 1843, Anna published the book Photographs of British Algae: Cyanotype Impressions with handwritten text and cyanotype photographs. It is considered the first book of photographs ever published. Weaving together histories of women, science, and art, The Bluest of Blues will inspire young readers to embark on their own journeys of discovery and creativity.

    Bob was a studious planner who wanted to grow up to be a doctor. Joe dreamed of making his fortune in show business and loved magic tricks and problem-solving.When an accident left Bob recovering in a darkened basement, the brothers began experimenting with ultraviolet light and fluorescent paints. Together they invented a whole new kind of color, one that glows with an extra-special intensity--Day-Glo.This cover reproduction is not printed with Day-Glo colors. The actual book, however, is printed using three Day-Glo colors: Saturn Yellow, Fire Orange, and Signal Green.

    She knew how many miles it was to the moon (and how many back). She loved studying algebra and geometry and calculus and using math to solve problems in the outside world.Soon math led her to MIT and then to helping NASA put a man on the moon! She handwrote code that would allow the spacecraft’s computer to solve any problems it might encounter. Apollo 8. Apollo 9. Apollo 10. Apollo 11. Without her code, none of those missions could have been completed.Dean Robbins and Lucy Knisley deliver a lovely portrayal of a pioneer in her field who never stopped reaching for the stars.

    Since inventing begins with experimenting, Frank spends a lot of time in his “laboratory” (i.e. his back porch) trying out his ideas, such as building a double-handled handcar that whizzes past the single-handled cars in his neighborhood. What Frank loves most, though, is experimenting with liquids. When he invents his own yummy flavored soda water drink, his friends love it! And this gets him to thinking: “I wonder what this drink would taste like frozen?” Though he doesn't yet realize it, his curiosity will lead to his best invention ever: the Popsicle!In this innovative picture book, Anne Renaud tells a lively story inspired by a real person and true events. Budding scientists will be inspired to emulate the way Frank follows his curiosity, works hard and never gives up --- a growth mindset in action. Interwoven within the story are full-page illustrated instructions for four science experiments that Frank performs, so readers can try them at home or school. Thoroughly researched back matter provides additional historical notes, photos and a bibliography. This readable book covers social studies topics including early twentieth-century history and inventions and inventors, as well as science topics, such as simple chemistry experiments and an overview of the skills and strategies of scientific inquiry.

    What she is, though, is a genius at math. When she grows up, she finds a way to first study math at a university (by sitting in, not actually enrolling) and then to teach it (by doing so for free). She also manages to do her own research into some of the most pressing math and physics problems of the day. And though she doesn't get much credit during her lifetime, her discoveries continue to influence how we understand the world today.Bestselling and award-winning Helaine Becker has crafted an engaging look at the life of Emmy Noether, a contemporary of Einstein's and one of the most influential, though little known, mathematicians of the twentieth century. Despite the obstacles she faced as a woman in a male-dominated field, and as a Jew who had to flee the Nazis, Emmy still accomplished a great deal. Artwork by Kari Rust uses touches of humor for emphasis and a golden glowing effect around Emmy to visually express her brilliance and ideas. Back matter includes a biographical note, explanations of complex mathematical concepts and suggestions for further reading. There are curriculum links to physics and mathematics --- subjects portrayed here as fascinating and exciting --- and poignant real-life character education lessons on courage and perseverance.
