Winner of the W.W. Howells Book Prize from the American Anthropological Association and named one of the best science books of 2021 by Science News “DeSilva takes us on a brilliant, fun, and scientifically deep stroll through history, anatomy, and evolution, in order to illustrate the powerful story of how a particular mode of movement helped make us one of the most wonderful, dangerous and fascinating species on Earth.”—Agustín Fuentes, Professor of Anthropology, Princeton University and author of Why We Believe: Evolution and the Human Way of Being “Breezy popular science at its best. . . . Makes a compelling case overall.”—Science News Blending history, science, and culture, a stunning and highly engaging evolutionary story exploring how walking on two legs allowed humans to become the planet’s dominant species. Humans are the only mammals to walk on two, rather than four legs—a locomotion known as bipedalism. We strive to be upstanding citizens, honor those who stand tall and proud, and take a stand against injustices. We follow in each other’s footsteps and celebrate a child’s beginning to walk. But why, and how, exactly, did we take our first steps? And at what cost? Bipedalism has its drawbacks: giving birth is more difficult and dangerous; our running speed is much slower than other animals; and we suffer a variety of ailments, from hernias to sinus problems. In First Steps, paleoanthropologist Jeremy DeSilva explores how unusual and extraordinary this seemingly ordinary ability is. A seven-million-year journey to the very origins of the human lineage, First Steps shows how upright walking was a gateway to many of the other attributes that make us human—from our technological abilities, our thirst for exploration, our use of language–and may have laid the foundation for our species’ traits of compassion, empathy, and altruism. Moving from developmental psychology labs to ancient fossil sites throughout Africa and Eurasia, DeSilva brings to life our adventure walking on two legs. Delving deeply into the story of our past and the new discoveries rewriting our understanding of human evolution, First Steps examines how walking upright helped us rise above all over species on this planet. First Steps includes an eight-page color photo insert.

The inspiring story of four-year-old Sarah Roberts, the first African American girl to try to integrate a white school, and how her experience in 1847 set greater change in motion. Junior Library Guild Selection 2017 Orbis Pictus Honor Book Chicago Public LibraryKids Best of the Best Book 2016 A Nerdy Book Club Best Nonfiction Book of 2016 An NCSS Notable Social Studies Trade Book of 2017 In 1847, a young African American girl named Sarah Roberts was attending a school in Boston. Then one day she was told she could never come back. She didn't belong. The Otis School was for white children only. Sarah deserved an equal education, and the Roberts family fought for change. They made history. Roberts v. City of Boston was the first case challenging our legal system to outlaw segregated schools. It was the first time an African American lawyer argued in a supreme court. These first steps set in motion changes that ultimately led to equality under the law in the United States. Sarah's cause was won when people--black and white--stood together and said, No more. Now, right now, it is time for change! With gorgeous art from award-winning illustrator E. B. Lewis, The First Step is an inspiring look at the first lawsuit to demand desegregation--long before the American Civil Rights movement, even before the Civil War. Backmatter includes: integration timeline, bios on key people in the book, list of resources, and author's note.

A major aspect of mathematical training and its benefit to society is the ability to use logic to solve problems. The American Mathematics Competitions have been given for more than fifty years to millions of students. This book considers the basic ideas behind the solutions to the majority of these problems, and presents examples and exercises from past exams to illustrate the concepts. Anyone preparing for the Mathematical Olympiads will find many useful ideas here, but people generally interested in logical problem solving should also find the problems and their solutions stimulating. The book can be used either for self-study or as topic-oriented material and samples of problems for practice exams. Useful reading for anyone who enjoys solving mathematical problems, and equally valuable for educators or parents who have children with mathematical interest and ability.

"It's a big, big world It's easy to get lost in it..." —Justin Bieber, "Up" I love those lines in the lyrics. Sometimes I feel like that's what everyone's expecting. My world got very big, very fast, and a lot of people expect me to get lost in it. I grew up in a small town in Canada. I taught myself to sing in front of my bedroom mirror and to play guitar on a hand-me-down. My mom posted my first videos on YouTube. Never in my wildest dreams did I think that I'd sell millions of records, sing for the president of the United States and sell out a massive arena tour. So no, I'm not lost. Not at all. If anything, onstage in front of my fans, I'm home. I'm found. And that's what this book is about: my journey, from singing and busking on the sidewalk in Stratford, Ontario, to performing and showing my appreciation to millions of fans all over the world for making this dream a reality. My music and lyrics give a glimpse of what's in my heart, but I think this book is a window into my world. In here are hundreds of pictures of me that no one's ever seen before, and I'll tell you about who I was before I joined forces with Scooter Braun and Usher and got a record deal, and who I've become since I've been blessed with the opportunity to share my music with the world. This is my gift to you, the fans who've supported and been with me on this amazing journey every step of the way.
