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.Einführung in die Chromatographie

Par Judith Shapiro. 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.100 Events That Shaped World History (100 Series)

Par Nima Bassiri. 2024
Uncovers a powerful relationship between pathology and money: beginning in the nineteenth century, the severity of mental illness was measured…
against a patient’s economic productivity. Madness and Enterprise reveals the economic norms embedded within psychiatric thinking about mental illness in the North Atlantic world. Over the course of the nineteenth century, various forms of madness were subjected to a style of psychiatric reasoning that was preoccupied with money. Psychiatrists across Western Europe and the United States attributed financial and even moral value to an array of pathological conditions, such that some mental disorders were seen as financial assets and others as economic liabilities. By turning to economic conduct and asking whether potential patients appeared capable of managing their financial affairs or even generating wealth, psychiatrists could often bypass diagnostic uncertainties about a person’s mental state. Through an exploration of the intertwined histories of psychiatry and economic thought, Nima Bassiri shows how this relationship transformed the very idea of value in the modern North Atlantic, as the most common forms of social valuation—moral value, medical value, and economic value—were rendered equivalent and interchangeable. If what was good and what was healthy were increasingly conflated with what was remunerative (and vice versa), then a conceptual space opened through which madness itself could be converted into an economic form and subsequently redeemed—and even revered.The Hate Next Door: Undercover within the New Face of White Supremacy
Par Matson Browning. 2023
The changing face of hate is on your doorstep…Matt Browning, an undercover detective in Arizona, thought he knew what hate…
looked like; that is, until he got a front row seat to White supremacy. What followed was a career of hardship and danger, and what he uncovered can no longer go left untold.For more than twenty-five years, Browning has been infiltrating, documenting, and disrupting white supremacy movements from the inside, gaining an intimate vantage point to the KKK, skinheads, border militias, Proud Boys, and other White Power groups, as they organized and grew, their ranks alarmingly including police force and military veterans. Together with his intrepid wife, Tawni, he adopted fake IDs and ideologies, seeking the arrest of its participants—none more so than J.T. Ready, a neo-Nazi who took "hunting trips" for border migrants while gaining mainstream acceptance as a political candidate—and terrorizing Browning's family. What others dismissed as fringe groups, Browning quickly recognized as large and interconnecting organizations permeating into every facet of American society, effectively spreading their dangerous and repugnant rhetoric at unprecedented speeds. Today, after the violent storming of the Capitol on January 6th, the threat posed by these toxic organizations can no longer be ignored by the public at large.In this imperative and gripping narrative, Browning gives readers the inside story of modern-day White supremacy in America in all of its ugly variation. Following his dramatic, high-stakes attempts to take down powerful White supremacists, the torment he faced whilst working undercover, and his eventual creation of the international Skinhead Intelligence Network, The Hate Next Door is a riveting, enlightening, and essential look at the what, where, when, and why of white supremacist groups, how to identify them, and why we must all do everything in our power to fight against them.General Relativity: The Theoretical Minimum (The Theoretical Minimum)
Par Leonard Susskind, André Cabannes. 2023
The latest volume in the New York Times–bestselling physics series explains Einstein&’s masterpiece: the general theory of relativity He taught us…
classical mechanics, quantum mechanics, and special relativity. Now, physicist Leonard Susskind, assisted by a new collaborator, André Cabannes, returns to tackle Einstein&’s general theory of relativity. Starting from the equivalence principle and covering the necessary mathematics of Riemannian spaces and tensor calculus, Susskind and Cabannes explain the link between gravity and geometry. They delve into black holes, establish Einstein field equations, and solve them to describe gravity waves. The authors provide vivid explanations that, to borrow a phrase from Einstein himself, are as simple as possible (but no simpler). An approachable yet rigorous introduction to one of the most important topics in physics, General Relativity is a must-read for anyone who wants a deeper knowledge of the universe&’s real structure.Wasteland: The Secret World of Waste and the Urgent Search for a Cleaner Future
Par Oliver Franklin-Wallis. 2023
NAMED A BEST BOOK OF THE YEAR 2023 BY THE NEW YORKER, THE GUARDIAN, and KIRKUS REVIEWS An award-winning investigative…
journalist takes a deep dive into the global waste crisis, exposing the hidden world that enables our modern economy—and finds out the dirty truth behind a simple question: what really happens to what we throw away? In Wasteland, journalist Oliver Franklin-Wallis takes us on a shocking journey inside the waste industry—the secretive multi-billion dollar world that underpins the modern economy, quietly profiting from what we leave behind. In India, he meets the waste-pickers on the front line of the plastic crisis. In the UK, he journeys down sewers to confront our oldest—and newest—waste crisis, and comes face-to-face with nuclear waste. In Ghana, he follows the after-life of our technology and explores the global export network that results in goodwill donations clogging African landfills. From an incinerator to an Oklahoma ghost-town, Franklin-Wallis travels in search of the people and companies that really handle waste—and on the way, meets the innovators and campaigners pushing for a cleaner and less wasteful future. With this mesmerizing, thought-provoking, and occasionally terrifying investigation, Oliver Franklin-Wallis tells a new story of humanity based on what we leave behind, and along the way, he shares a blueprint for building a healthier, more sustainable world—before we&’re all buried in trash.Science journalist Sally Adee breaks open the field of bioelectricity—the electric currents that run through our bodies and every living…
thing—its misunderstood history, and why new discoveries will lead to new ways around antibiotic resistance, cleared arteries, and new ways to combat cancer. You may be familiar with the idea of our body's biome: the bacterial fauna that populate our gut and can so profoundly affect our health. In We Are Electric we cross into new scientific understanding: discovering your body's electrome. Every cell in our bodies—bones, skin, nerves, muscle—has a voltage, like a tiny battery. It is the reason our brain can send signals to the rest of our body, how we develop in the womb, and why our body knows to heal itself from injury. When bioelectricity goes awry, illness, deformity, and cancer can result. But if we can control or correct this bioelectricity, the implications for our health are remarkable: an undo switch for cancer that could flip malignant cells back into healthy ones; the ability to regenerate cells, organs, even limbs; to slow aging and so much more. The next scientific frontier might be decrypting the bioelectric code, much the way we did the genetic code. Yet the field is still emerging from two centuries of skepticism and entanglement with medical quackery, all stemming from an 18th-century scientific war about the nature of electricity between Luigi Galvani (father of bioelectricity, famous for shocking frogs) and Alessandro Volta (inventor of the battery). In We Are Electric, award-winning science writer Sally Adee takes readers through the thrilling history of bioelectricity and into the future: from the Victorian medical charlatans claiming to use electricity to cure everything from paralysis to diarrhea, to the advances helped along by the giant axons of squids, and finally to the brain implants and electric drugs that await us—and the moral implications therein. The bioelectric revolution starts here.As Gods: A Moral History of the Genetic Age

time. As biologist and historian Matthew Cobb shows in As Gods, this achievement was one many scientists have feared from the start of the genetic age. Four times in the last fifty years, geneticists, frightened by their own technology, have called a temporary halt to their experiments. They ought to be frightened: Now we have powers that can target the extinction of pests, change our own genes, or create dangerous new versions of diseases in an attempt to prevent future pandemics. Both awe-inspiring and chilling, As Gods traces the history of genetic engineering, showing that this revolutionary technology is far too important to be left to the scientists. They have the power to change life itself, but should we trust them to keep their ingenuity from producing a hellish reality?The Women's House of Detention: A Queer History of a Forgotten Prison
Par Hugh Ryan. 2022
This singular history of a prison, and the queer women and trans people held there, is a window into the…
policing of queerness and radical politics in the twentieth century. The Women&’s House of Detention, a landmark that ushered in the modern era of women&’s imprisonment, is now largely forgotten. But when it stood in New York City&’s Greenwich Village, from 1929 to 1974, it was a nexus for the tens of thousands of women, transgender men, and gender-nonconforming people who inhabited its crowded cells. Some of these inmates—Angela Davis, Andrea Dworkin, Afeni Shakur—were famous, but the vast majority were incarcerated for the crimes of being poor and improperly feminine. Today, approximately 40 percent of the people in women&’s prisons identify as queer; in earlier decades, that percentage was almost certainly higher. Historian Hugh Ryan explores the roots of this crisis and reconstructs the little-known lives of incarcerated New Yorkers, making a uniquely queer case for prison abolition—and demonstrating that by queering the Village, the House of D helped defined queerness for the rest of America. From the lesbian communities forged through the Women&’s House of Detention to the turbulent prison riots that presaged Stonewall, this is the story of one building and much more: the people it caged, the neighborhood it changed, and the resistance it inspired.

brains—and what we can do to fix it. The original internet was not designed to make us upset, distracted, confused, and outraged. But something unexpected happened at the turn of the last decade, when a handful of small features were quietly launched at social media companies with little fanfare. Together, they triggered a cascading set of dramatic changes to how media, politics, and society itself operate—inadvertently creating an Outrage Machine we cannot ignore. Author, designer, and media researcher Tobias Rose-Stockwell shares the defining shifts caused by these technologies, and how they have ignited a society-wide crisis of trust. Drawing from cutting-edge research and vivid personal anecdotes, Rose-Stockwell illustrates how social media has bound us to an unprecedented system of public performance, training us to react rather than reflect, and attack rather than debate.Outrage Machine reveals the triggers and tactics used to exploit our anger, unpacking how these tools hack our deep tribal instincts and psychological vulnerabilities, and how they have become opportunistic platforms for authoritarians and a threat to democratic norms everywhere. But this book is not just about the problem. In a story spanning continents and generations, Rose-Stockwell explores how every new media technology disrupts our ability to make sense of the world, from the printing press to the telegraph, from radio to television. Outrage Machine situates social media within a historical cycle of confusion, violence, and emerging tolerance. Using clear language and powerful illustrations, this book reveals the magnitude of the challenges we face, while offering realistic solutions and a promising pathway out.Physiological and Biochemical Zoology, volume 96 number 6 (November/December 2023)

First, based on…
several criteria, the region is identified as homogeneous country groupings of diversity, a multi-polar spatial system, and as program regions of QUAD and I2U2 for action programs and investment transcending many nations but mostly the ocean space of the Indo-Pacific, connecting all megacities sub-regions spatially and functionally. Then, the megacities with problems and prospects for economic integration are studied from the point of view of regional economics and international trade, and finally, the rural–urban interface with case studies of selected countries is presented. Prospects of systems of megacities and individual megacities for regional economies are designed. Existing interconnections through rail, air, and ocean of megacity systems, their capacity, performance, and potential are analyzed for emerging issues. International trade among the megacity systems/countries with emerging issues and barriers are presented. The mobility of money, goods, and services among the systems of megacities is analyzed. Rule-based diplomacy and other emerging options are discussed to sustain the above calls for a study of the Security of the Indo-Pacific region. Finally, the emerging architecture for megacity system governance is also presented.Out of 21 megacities in the Indo-Pacific, an in-depth study of a few in India and Japan in the Indo-Pacific region for effective economic interventions in the megacities system at the city level was studied. COVID-19 has affected most of the countries in the Indo-Pacific. With a contraction of GDP and a GDP growth rate negative, the number below the poverty level increased. Foreign Direct Investment is not forthcoming in any of these countries. Job creation becomes a priority in addition to public health concerns connected with COVID-19.Electrical Machines and Their Applications

Par King-Ning Tu, Yingxia Liu. 2024
In this invaluable resource for graduate students and practicing professionals, Tu and Liu provide a comprehensive account of electromigration and…
give a practical guide on how to manage its effects in microelectronic devices, especially newer devices that make use of 3D architectures. In the era of big data and artificial intelligence, next-generation microelectronic devices for consumers must be smaller, consume less power, cost less, and, most importantly, have higher functionality and reliability than ever before. However, with miniaturization, the average current density increases, and so does the probability of electromigration failure. This book covers all critical elements of electromigration, including basic theory, various failure modes induced by electromigration, methods to prevent failure, and equations for predicting mean-time-to-failure. Furthermore, effects such as stress, Joule heating, current crowding, and oxidation on electromigration are covered, and the new and modified mean-time-to-failure equations based on low entropy production are given. Readers will be able to apply this information to the design and application of microelectronic devices to minimize the risk of electromigration-induced failure in microelectronic devices. This book essential for anyone who wants to understand these critical elements and minimize their effects. It is particularly valuable for both graduate students of electrical engineering and materials science engineering and engineers working in the semiconductor and electronic packaging technology industries.Mathematical Methods for Life Sciences
