    Nathaniel Bowditch grew up in a sailor’s world—Salem in the early days, when tall-masted ships from foreign ports crowded the wharves. But Nat didn’t promise to have the makings of a sailor; he was too physically small. Nat may have been slight of build, but no one guessed that he had the persistence and determination to master sea navigation in the days when men sailed only by “log, lead, and lookout.” Nat’s long hours of study and observation, collected in his famous work, The American Practical Navigator (also known as the “Sailors’ Bible”), stunned the sailing community and made him a New England hero.

    But what if we took these big, hard-to-imagine objects and events and compared them to things we can see, feel and touch? Instantly, we'd see our world in a whole new way." So begins this endlessly intriguing guide to better understanding all those really big ideas and numbers children come across on a regular basis. Author David J. Smith has found clever devices to scale down everything from time lines (the history of Earth compressed into one year), to quantities (all the wealth in the world divided into one hundred coins), to size differences (the planets shown as different types of balls). Accompanying each description is a kid-friendly drawing by illustrator Steve Adams that visually reinforces the concept. By simply reducing everything to human scale, Smith has made the incomprehensible easier to grasp, and therefore more meaningful. The children who just love these kinds of fact-filled, knock-your-socks-off books will want to read this one from cover to cover. It will find the most use, however, as an excellent classroom reference that can be reached for again and again when studying scale and measurement in math, and also for any number of applications in social studies, science and language arts. For those who want to delve a little deeper, Smith has included six suggestions for classroom projects. There is also a full page of resource information at the back of the book.

    As we dream with him, we are taken further and further into mathematical theory, where ideas eventually take flight, until everyone--from those who fumble over fractions to those who solve complex equations in their heads--winds up marveling at what numbers can do.Hans Magnus Enzensberger is a true polymath, the kind of superb intellectual who loves thinking and marshals all of his charm and wit to share his passions with the world. In The Number Devil, he brings together the surreal logic of Alice in Wonderland and the existential geometry of Flatland with the kind of math everyone would love, if only they had a number devil to teach them.

    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.
