The Maker movement has been an excellent opportunity for people to become producers rather than just consumers, and schools are…
recognizing the value of offering students the tools, materials, and skills necessary to design sophisticated and meaningful projects. But teaching technical skills should not be the end goal: At its best, a Maker education teaches students to think and act in creative ways that can be applied to difficult challenges in all areas of life.Three Modes of Making provides a framework for Maker courses in upper grades that teach students creative-process skills through three key Maker modes: Imitation, Modification, and Innovation. Educators will learn the differences between the three Maker modes, their associated skill sets, and gain concrete methods to teach, document, and assess these skills. Through this approach, teachers will enable students to apply them to different creative needs.By focusing on how to teach skill development rather than merely how to build specific objects, Three Modes of Making enables students to improve and enhance their creative skills, and learn ways to apply them to a wide variety of challenges. This book is a road map to developing the creative problem solvers that the world needs for the future.Par Georg Schwedt. 2024

China’s huge environmental challenges affect not only the health and well-being of China but the very future of the planet.…
In this fully revised and updated third edition of her acclaimed book, noted scholar of Chinese environmentalism Judith Shapiro explores China’s struggle to achieve the ‘ecological civilization’ championed by Xi Jinping since 2017. Drawing on six core analytical concepts - globalization, governance, national identity, civil society, environmental justice, and extractivism - Shapiro ably demonstrates the multifaceted and complex nature of this struggle. China’s precipitous economic growth has carried a heavy cost in air and water pollution, soil contamination, and loss of habitat for the biodiversity upon which human life depends. But its quest for sustainability has been further hampered by authoritarian governance patterns, soaring middle class consumption, the need to provide employment and safety nets for a population of more than one billion, and a manufacturing sector thirsty to secure global resources and sell to new markets. Transformation to a more sustainable development model is still possible. But, as Shapiro persuasively argues, this will require humility, creativity, and a rejection of business as usual. China – and the planet – are at a pivotal moment.Par Bill Yenne. 2022

inquiry that chronicles one woman&’s experience of life in Northern California during the worst fire season on record.A MOST-ANTICIPATED BOOK: The New York Times, The Los Angeles Times, The San Francisco Chronicle, The Saturday Evening Post, Poets & Writers, The Millions, Alta, Heat Map NewsTold in luminous, perceptive prose, The Last Fire Season is a deeply incisive inquiry into what it really means—now—to live in relationship to the elements of the natural world. When Manjula Martin moved from the city to the woods of Northern California, she wanted to be closer to the wilderness that she had loved as a child. She was also seeking refuge from a health crisis that left her with chronic pain, and found a sense of healing through tending her garden beneath the redwoods of Sonoma County. But the landscape that Martin treasured was an ecosystem already in crisis. Wildfires fueled by climate change were growing bigger and more frequent: each autumn, her garden filled with smoke and ash, and the local firehouse siren wailed deep into the night.In 2020, when a dry lightning storm ignited hundreds of simultaneous wildfires across the West and kicked off the worst fire season on record, Martin, along with thousands of other Californians, evacuated her home in the midst of a pandemic. Both a love letter to the forests of the West and an interrogation of the colonialist practices that led to their current dilemma, The Last Fire Season, follows her from the oaky hills of Sonoma County to the redwood forests of coastal Santa Cruz, to the pines and peaks of the Sierra Nevada, as she seeks shelter, bears witness to the devastation, and tries to better understand fire&’s role in the ecology of the West. As Martin seeks a way to navigate the daily experience of living in a damaged body on a damaged planet, she comes to question her own assumptions about nature and the complicated connections between people and the land on which we live.Par Michael Ruhlman. 2001

about these boats that has captured the popular imagination? With his "lively blend of reportage [and] reflection" (Los Angeles Times), Michael Ruhlman sets off for a renowned boatyard in Martha's Vineyard to follow the construction of two boats-Rebecca, a 60-foot modern pleasure schooner, and Elisa Lee, a 32-foot powerboat. Filled with exquisite details and stories of the sea, this exciting exploration of a nearly forgotten craft and the colorful personalities involved will enthrall wooden boat owners as well as craftspeople of every stripe, nature enthusiasts, and fans of compelling nonfiction.Par Erik Larson. 1999
At the dawn of the twentieth century, a great confidence suffused America. Isaac Cline was one of the era's new…
men, a scientist who believed he knew all there was to know about the motion of clouds and the behavior of storms. The idea that a hurricane could damage the city of Galveston, Texas, where he was based, was to him preposterous, "an absurd delusion." It was 1900, a year when America felt bigger and stronger than ever before. Nothing in nature could hobble the gleaming city of Galveston, then a magical place that seemed destined to become the New York of the Gulf.That August, a strange, prolonged heat wave gripped the nation and killed scores of people in New York and Chicago. Odd things seemed to happen everywhere: A plague of crickets engulfed Waco. The Bering Glacier began to shrink. Rain fell on Galveston with greater intensity than anyone could remember. Far away, in Africa, immense thunderstorms blossomed over the city of Dakar, and great currents of wind converged. A wave of atmospheric turbulence slipped from the coast of western Africa. Most such waves faded quickly. This one did not.In Cuba, America's overconfidence was made all too obvious by the Weather Bureau's obsession with controlling hurricane forecasts, even though Cuba's indigenous weathermen had pioneered hurricane science. As the bureau's forecasters assured the nation that all was calm in the Caribbean, Cuba's own weathermen fretted about ominous signs in the sky. A curious stillness gripped Antigua. Only a few unlucky sea captains discovered that the storm had achieved an intensity no man alive had ever experienced.In Galveston, reassured by Cline's belief that no hurricane could seriously damage the city, there was celebration. Children played in the rising water. Hundreds of people gathered at the beach to marvel at the fantastically tall waves and gorgeous pink sky, until the surf began ripping the city's beloved beachfront apart. Within the next few hours Galveston would endure a hurricane that to this day remains the nation's deadliest natural disaster. In Galveston alone at least 6,000 people, possibly as many as 10,000, would lose their lives, a number far greater than the combined death toll of the Johnstown Flood and 1906 San Francisco Earthquake.And Isaac Cline would experience his own unbearable loss.Meticulously researched and vividly written, Isaac's Storm is based on Cline's own letters, telegrams, and reports, the testimony of scores of survivors, and our latest understanding of the hows and whys of great storms. Ultimately, however, it is the story of what can happen when human arrogance meets nature's last great uncontrollable force. As such, Isaac's Storm carries a warning for our time.We use water, electricity, and the internet every day--but how do they actually work? And what&’s the plan to keep…

This book is written by two world-recognized experts in radio frequency (RF) systems for particle accelerators and is based on…
many years of experience in dealing with the multipactor phenomenon. The authors introduce and review multipactor in RF cavities for scientists and engineers working in the field of accelerator physics and technology. The multipactor phenomenon of unintended electron avalanches occurs in the RF cavities commonly and quite often is a performance-limiting factor. The book starts with an Introductory Overview which contains historical observations and brief description of most common aspects of the phenomenon. Part I deals with the multipactor in a flat gap. It starts with description of the dynamics of electrons, derivation of the stability condition and analyzing influence of several factors on the multipactor. Then, the initial considerations are extended to derive a generalized phase stability and finally a particular case, called ping-pong multipacting, is considered. The part one is concluded with a brief review of computer codes used in multipactor simulations. Part II is dedicated to the multipactor in crossed RF fields, the typical situation in accelerating cavities. Two cases of MP are considered: a two-point multipactor near the cavity equator in elliptical cavities and a one-point multipactor. Part III describes optimization of the cavity shapes geared toward designing multipactor-free structures. The book will serve as an importance reference on multipactor for those involved in developing and operating radio frequency cavities for particle accelerators.Par Álvaro Rocha, Carlos Ferrás, Waldo Ibarra. 2023

bodies. Synthetic biology will revolutionize how we define family, how we identify disease and treat aging, where we make our homes, and how we nourish ourselves. This fast-growing field—which uses computers to modify or rewrite genetic code—has created revolutionary, groundbreaking solutions such as the mRNA COVID vaccines, IVF, and lab-grown hamburger that tastes like the real thing. It gives us options to deal with existential threats: climate change, food insecurity, and access to fuel. But there are significant risks. Who should decide how to engineer living organisms? Whether engineered organisms should be planted, farmed, and released into the wild? Should there be limits to human enhancements? What cyber-biological risks are looming? Could a future biological war, using engineered organisms, cause a mass extinction event? Amy Webb and Andrew Hessel&’s riveting examination of synthetic biology and the bioeconomy provide the background for thinking through the upcoming risks and moral dilemmas posed by redesigning life, as well as the vast opportunities waiting for us on the horizon.Par Thomas Suddendorf, Jonathan Redshaw, Adam Bulley. 2022

the most powerful tools at our disposal. In The Invention of Tomorrow, cognitive scientists Thomas Suddendorf, Jonathan Redshaw, and Adam Bulley argue that its emergence transformed humans from unremarkable primates to creatures that hold the destiny of the planet in their hands. Drawing on their own cutting-edge research, the authors break down the science of foresight, showing us where it comes from, how it works, and how it made our world. Journeying through biology, psychology, history, and culture, they show that thinking ahead is at the heart of human nature—even if we often get it terribly wrong. Incisive and expansive, The Invention of Tomorrow offers a fresh perspective on the human tale that shows how our species clawed its way to control the future.Par Professor Joseph L Graves Jr.. 2022
Why understanding evolution—the most reviled branch of science—can help us all, from fighting pandemics to undoing racism Evolutionary science has long…
been regarded as conservative, a tool for enforcing regressive ideas, particularly about race and gender. But in A Voice in the Wilderness, evolutionary biologist Joseph L. Graves Jr.—once styled as the &“Black Darwin&”—argues that his field is essential to social justice. He shows, for example, why biological races do not exist. He dismantles recent work in &“human biodiversity&” seeking genes to explain the achievements of different ethnic groups. He decimates homophobia, sexism, and classism as well. As a pioneering Black biologist, a leftist, and a Christian, Graves uses his personal story—his journey from a child of Jim Crow to a major researcher and leader of his peers—to rewrite his field. A Voice in the Wilderness is a powerful work of scientific anti-racism and a moving account of a trailblazing life.Par Rebecca Boyle. 2024
