    It was the first trip across an engineering marvel that had taken nearly fourteen years to construct. The woman's husband was the chief engineer, and he knew all about the dangerous new technique involved. The woman insisted she learn as well. When he fell ill mid-construction, her knowledge came in handy. She supervised every aspect of the project while he was bedridden, and she continued to learn about things only men were supposed to know:math,science,engineering.Women weren't supposed to be engineers. But this woman insisted she could do it all, and her hard work helped to create one of the most iconic landmarks in the world. This is the story of Emily Roebling, the secret engineer behind the Brooklyn Bridge, from author-illustrator Rachel Dougherty.

    When Joan was thirteen, she had a life-changing experience. The archangel Michael appeared in a vision and told her that she would save the kingdom of France and lead the dauphin (heir to the throne) to Reims Cathedral to be crowned king. Calling herself the Maid of God, Joan set off to gather an army, win a number of crucial battles, and install the dauphin on the French throne. Although the king later deserted her when France’s enemies put her on trial for heresy and burned her at the stake, her bravery and faith inspired the French people and led them to victory. Demi has drawn Joan’s battles and triumphs with exquisite detail inspired by the stained glass, architecture, painting, and sculpture of the fifteenth century.

    They take their time in the prehistoric jungle, collecting fruits and leaves and using their tiny teeth to munch them. Some dinosaurs are big and fast. With huge teeth and claws, they steal food from small dinosaurs, and they’re always hungry for more. So when three big dinosaurs come across one small one, what — or who — can save the little plant-eater? Beautifully drawn and brightly colored, Charlotte Voake’s imaginative introduction to the concept of size brims with visual humor and culminates in a sweet surprise ending.

    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.

    Author of the Declaration of Independence. Obsessive prehistoric mammal hunter It's true! In this little-known slice of American history, see Thomas Jefferson as never before!In the late 1700's, America was a new nation, with a vast west that held age-old secrets: Bones!

Jefferson needed to find out. Funding explorers, including the famed Lewis and Clark, Jefferson sought to find a complete prehistoric mastodon skeleton - one which would advance the young science of paleontology, but would also put this upstart young country on the world stage. Follow along on the incredible journey - full of triumphs and disappointments, discoveries and shipwrecks, ridicule and victory.Author Candice Ransom researched this amazing story for years before telling this tale, closely collaborating with Jefferson scholars and natural history experts.

     Christopher McKinlay has been featured in Wired Magazine for his groundbreaking analysis of OkCupid. For the first time he’s showing non-experts how to turn Internet dating on its head. This concise guide will show anyone (straight, gay, male or female) the procedure McKinlay used to meet his fiancee and how the same ideas can transform their lives and bring them from browsing to contact. One summer evening while logged into a supercomputer in Colorado waiting for a large computation, McKinlay was killing time on OkC when he was troubled by a problem: what if large groups of people responded to OkCupid’s personality questionnaire in statistically similar ways? He created custom software to scrape data from the site, collecting over 6,000,000 answers to OkC’s “match questions” from more than 20,000 real users. This data made clear he’d been using the site the wrong way. Based on his findings, McKinlay (a mathematics PhD), optimized his own profile. The transformation was profound. He went from showing a “match percentage” of 90% with a few hundred women in the L.A. area to showing 90% or higher with over 30,000 local women. Unsolicited messages from attractive strangers began flooding his inbox. With a foreword by Jon Finkel, McKinlay’s insightful how-to will teach you how to benefit from the buried statistical patterns of online romance.
