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 First Steps in Seeing is about the eyes, and how they capture an image and convert it to the neural messages that ultimately result in visual experience. A full appreciation of how the eyes work is rooted in diverse areas of science-optics; biochemistry and photochemistry; molecular biology, cell biology, neurobiology, and evolutionary biology; psychology and psychophysics. The findings related to vision from any one of these fields are not difficult to understand in themselves, but, in order to be clear and precise, each discipline has developed its own set of words and conceptual relations-in effect, its own language-and for those wanting a broad introduction to vision these separate languages can present more of an impediment to understanding than an aid. However, what lies beneath these words usually has a beautiful simplicity, and it is the aim of The First Steps in Seeing to describe how we see in a manner that is understandable to all. In this book, the use of technical terms is restricted, and several hundred full-color illustrations ensure that the terms that are used are associated with a picture, icon, or graph that visually expresses their meaning. Experimental findings have been recast in terms of the natural world whenever possible, and broad themes bring together lines of thought that are often treated separately. Fourteen main chapters form a "thread" that tells the main scientific story and can be read without specialized knowedge or reliance on other sources. This thread is linked to fourteen discussions which explore certain crucial topics in greater depth. Notes link the material presented in the thread and in the special topics discussions to important review articles and seminal research papers. The First Steps in Seeing is an innovative, authoritative work that belongs in the library of anyone with an interest in visual perception.

Computer Graphics - First Mathematical Steps will help students to master basic Computer Graphics and the mathematical concepts which underlie this subject. They will be led to develop their own skills, and appreciate Computer Graphics techniques in both two and three dimensions. The presentation of the text is methodical, systematic and gently paced - everything translates into numbers and simple ideas. Sometimes students experience difficulty in understanding some of the mathematics in standard Computer Graphics books; this book can serve as a good introduction to more advanced texts. It starts from first principles and is sympathetically written for those with a limited mathematical background. Computer Graphics - First Mathematical Steps is suitable for supporting undergraduate programmes in Computers and also the newer areas of Computer Graphics and Visualization. It is appropriate for post-graduate conversion courses which develop expertise in Computer Graphics and CAD. It can also be used for enrichment topics for high-flying pre-college students, and for refresher/enhancement courses for computer graphics technicians.

Concepts of Biology is designed for the single-semester introduction to biology course for non-science majors, which for many students is their only college-level science course. As such, this course represents an important opportunity for students to develop the necessary knowledge, tools, and skills to make informed decisions as they continue with their lives. Rather than being mired down with facts and vocabulary, the typical non-science major student needs information presented in a way that is easy to read and understand. Even more importantly, the content should be meaningful. Students do much better when they understand why biology is relevant to their everyday lives. For these reasons, Concepts of Biology is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand.We also strive to show the interconnectedness of topics within this extremely broad discipline. In order to meet the needs of today's instructors and students, we maintain the overall organization and coverage found in most syllabi for this course. A strength of Concepts of Biology is that instructors can customize the book, adapting it to the approach that works best in their classroom. Concepts of Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand--and apply--key concepts.
