Human development is a long and steady process that began with stone tool making. Because of this skill, humans were able to adapt to climate changes, discover new territories, and invent new technologies. "Pressure knapping" is the common term for one method of creating stone tools, where a larger device or blade specifically made for this purpose is use to press out the stone tool. Pressure knapping was invented in different locations and at different points in time, representing the adoption of the Neolithic way of life in the Old world. Recent research on pressure knapping has led for the first time to a global thesis on this technique. The contributors to this seminal work combine research findings on pressure knapping from different cultures around the globe to develope a cohesive theory. This contributions to this volume represents a significant development to research on pressure knapping, as well as the field of lithic studies in general. This work will be an important reference for anyone studying the Paleolithic, Mesolithic, and Neolithic periods, lithic studies, technologies, and more generally, cultural transmission.

As research continues on the earliest migration of modern humans into North and South America, the current state of knowledge about these first Americans is continually evolving. Especially with recent advances in human genomic studies, both of living populations and ancient skeletal remains, new light is being shed in the ongoing quest toward understanding the full complexity and timing of prehistoric migration patterns. Paleoamerican Odyssey collects thirty-one studies presented at the 2013 conference by the same name, hosted in Santa Fe, New Mexico, by the Center for the Study of the First Americans at Texas A&M University. Providing an up-to-date view of the current state of knowledge in paleoamerican studies, the research gathered in this volume, presented by leaders in the field, focuses especially on late Pleistocene Northeast Asia, Beringia, and North and South America, as well as dispersal routes, molecular genetics, and Clovis and pre-Clovis archaeology.

When New York–based graphic designers and long-time friends Timothy Goodman and Jessica Walsh found themselves single at the same time, they decided to try an experiment. The old adage says that it takes 40 days to change a habit—could the same be said for love? So they agreed to date each other for 40 days, record their experiences in questionnaires, photographs, videos, texts, and artworks, and post the material on a website they would create for this purpose. What began as a small experiment between two friends became an Internet sensation, drawing 5 million unique (and obsessed) visitors from around the globe to their site and their story since it was launched in July 2013. 40 Days of Dating: An Experiment is a beautifully designed, expanded look at the experiment and the results, including a great deal of material that never made it onto the site, such as who they were as friends and individuals before the 40 days and who they have become since. Note: 40 Days of Dating has a special binding that allows it to open very flat by attaching the endpapers to the inside covers.

Have you ever wondered whether the forensic science you’ve seen on TV is anything like the real thing? There’s no better way to find out than to roll up your sleeves and do it yourself. This full-color book offers advice for setting up an inexpensive home lab, and includes more than 50 hands-on lab sessions that deal with forensic science experiments in biology, chemistry, and physics. You’ll learn the practical skills and fundamental knowledge needed to pursue forensics as a lifelong hobby—or even a career. The forensic science procedures in this book are not merely educational, they’re the real deal. Each chapter includes one or more lab sessions devoted to a particular topic. You’ll find a complete list of equipment and chemicals you need for each session. Analyze soil, hair, and fibers Match glass and plastic specimens Develop latent fingerprints and reveal blood traces Conduct drug and toxicology tests Analyze gunshot and explosives residues Detect forgeries and fakes Analyze impressions, such as tool marks and footprints Match pollen and diatom samples Extract, isolate, and visualize DNA samples Through their company, The Home Scientist, LLC (thehomescientist.com/forensics), the authors also offer inexpensive custom kits that provide specialized equipment and supplies you’ll need to complete the experiments. Add a microscope and some common household items and you’re good to go.

You will never look at your iPhone the same way again." -Dan Lyons, New York Times bestselling author of Disrupted Odds are that as you read this, an iPhone is within reach. But before Steve Jobs introduced us to "the one device," as he called it, a cell phone was merely what you used to make calls on the go. How did the iPhone transform our world and turn Apple into the most valuable company ever? Veteran technology journalist Brian Merchant reveals the inside story you won't hear from Cupertino-based on his exclusive interviews with the engineers, inventors, and developers who guided every stage of the iPhone's creation. This deep dive takes you from inside One Infinite Loop to 19th century France to WWII America, from the driest place on earth to a Kenyan pit of toxic e-waste, and even deep inside Shenzhen's notorious "suicide factories." It's a firsthand look at how the cutting-edge tech that makes the world work-touch screens, motion trackers, and even AI-made their way into our pockets. The One Device is a roadmap for design and engineering genius, an anthropology of the modern age, and an unprecedented view into one of the most secretive companies in history. This is the untold account, ten years in the making, of the device that changed everything.

“A lovely, fascinating book, which brings science to life.” —Alan Lightman Combining science, history, and adventure, Tom Shachtman “holds the reader’s attention with the skill of a novelist” as he chronicles the story of humans’ four-centuries-long quest to master the secrets of cold (Scientific American). “A disarming portrait of an exquisite, ferocious, world-ending extreme,” Absolute Zero and the Conquest of Cold demonstrates how temperature science produced astonishing scientific insights and applications that have revolutionized civilization (Kirkus Reviews). It also illustrates how scientific advancement, fueled by fortuitous discoveries and the efforts of determined individuals, has allowed people to adapt to—and change—the environments in which they live and work, shaping man’s very understanding of, and relationship, with the world. This “truly wonderful book” was adapted into an acclaimed documentary underwritten by the National Science Foundation and the Alfred P. Sloan Foundation, directed by British Emmy Award winner David Dugan, and aired on the BBC and PBS’s Nova in 2008 (Library Journal). “An absorbing account to chill out with.” —Booklist
