Book excerpt: NATIONAL BESTSELLER • A leading economist answers one of today’s trickiest questions: Why do some great ideas make it big while others fail to take off? “Brilliant, practical, and grounded in the very latest research, this is by far the best book I’ve ever read on the how and why of scaling.”—Angela Duckworth, CEO of Character Lab and New York Times bestselling author of Grit ONE OF THE MOST ANTICIPATED BOOKS OF 2022—Men’s Journal “Scale” has become a favored buzzword in the startup world. But scale isn't just about accumulating more users or capturing more market share. It's about whether an idea that takes hold in a small group can do the same in a much larger one—whether you’re growing a small business, rolling out a diversity and inclusion program, or delivering billions of doses of a vaccine. Translating an idea into widespread impact, says University of Chicago economist John A. List, depends on one thing only: whether it can achieve “high voltage”—the ability to be replicated at scale. In The Voltage Effect, List explains that scalable ideas share a common set of attributes, while any number of attributes can doom an unscalable idea. Drawing on his original research, as well as fascinating examples from the realms of business, policymaking, education, and public health, he identifies five measurable vital signs that a scalable idea must possess, and offers proven strategies for avoiding voltage drops and engineering voltage gains. You’ll learn: • How celebrity chef Jamie Oliver expanded his restaurant empire by focusing on scalable “ingredients” (until it collapsed because talent doesn’t scale) • Why the failure to detect false positives early on caused the Reagan-era drug-prevention program to backfire at scale • How governments could deliver more services to more citizens if they focused on the last dollar spent • How one education center leveraged positive spillovers to narrow the achievement gap across the entire community • Why the right set of incentives, applied at scale, can boost voter turnout, increase clean energy use, encourage patients to consistently take their prescribed medication, and more. By understanding the science of scaling, we can drive change in our schools, workplaces, communities, and society at large. Because a better world can only be built at scale.

Book excerpt: 'By far the best book I've ever read on the how and why of scaling. If you care about changing the world, or just want to make better decisions in your own life, The Voltage Effect is for you.' Angela Duckworth, CEO of Character Lab and New York Times bestselling author of Grit ________________ Why do some ideas make it big while others fail to take off? According to award-winning behavioural economist John List, the answer comes down to a single question: Can the idea scale? Countless enterprises fall apart the moment they scale; their positive results fizzle, they lose valuable time and money, and the great electric charge of potential that drove them early on disappears. In short, they suffer a voltage drop. Yet success and failure are not about luck - in fact, there is a rhyme and reason as to why some ideas fail and why some make it big. Certain ideas are predictably scalable, while others are predictably destined for disaster. In The Voltage Effect, University of Chicago economist John A. List explains how to identify the ideas that will be successful when scaled, and how to avoid those that won't. Drawing on his own original research, as well as fascinating examples from the realms of business, government, education, and public health, he details the five signature elements that cause voltage drops, and unpacks the four proven techniques for increasing positive results - or voltage gains - and scaling great ideas to their fullest potential. By understanding the science of scaling, we can drive change in our schools, workplaces, communities, and society at large. Because a better world can only be built at scale. ________________ 'One of the best economics books I have ever read - and an instant classic in behavioral economics.' Cass R. Sunstein, Robert Walmsley University Professor, Harvard University, and New York Times bestselling co-author of Nudge 'Thought-provoking and engaging. A must-read.'

Book excerpt: Can economics be passionate?… Can it center on people and what really matters to them day-in and day-out.… And help us understand their hidden motives for why they do what they do in everyday life? Uri Gneezy and John List are revolutionaries. Their ideas and methods for revealing what really works in addressing big social, business, and economic problems gives us new understanding of the motives underlying human behavior. We can then structure incentives that can get people to move mountains, change their behavior—or at least get a better deal. But finding the right incentive can be like looking for a needle in a haystack. Gneezy and List’s pioneering approach is to embed themselves in the factories, schools, communities, and offices where people work, live, and play. Then, through large-scale field experiments conducted “in the wild,” Gneezy and List observe people in their natural environments without them being aware that they are observed. Their randomized experiments have revealed ways to close the gap between rich and poor students; to stop the violence plaguing inner-city schools; to decipher whether women are really less competitive than men; to correctly price products and services; and to discover the real reasons why people discriminate. To get the answers, Gneezy and List boarded planes, helicopters, trains, and automobiles to embark on journeys from the foothills of Kilimanjaro to California wineries; from sultry northern India to the chilly streets of Chicago; from the playgrounds of schools in Israel to the boardrooms of some of the world’s largest corporations. In The Why Axis, they take us along for the ride, and through engaging and colorful stories, present lessons with big payoffs. Their revelatory, startling, and urgent discoveries about how incentives really work are both revolutionary and immensely practical. This research will change both the way we think about and take action on big and little problems. Instead of relying on assumptions, we can find out, through evidence, what really works. Anyone working in business, politics, education, or philanthropy can use the approach Gneezy and List describe in The Why Axis to reach a deeper, nuanced understanding of human behavior, and a better understanding of what motivates people and why.

Book excerpt: The Resonance Effect is both the author's story of her inspirational journey of having the courage to find her true calling and an account of the development of a remarkable newly rediscovered treatment, frequency specific microcurrent (FSM), that takes advantage of the body's ability to respond to frequencies in order to heal a number of chronic conditions. Carolyn McMakin, a chiropractor specializing in fibromyalgia and myofascial pain, describes her experience using a two-channel microcurrent device that has achieved astounding results that have changed medicine and created new possibilities for suffering patients over the past twenty years. Nerve pain, fibromyalgia, diabetic neuropathies, muscle pain, athletic performance, injury repair, joint pain, low back pain, neck pain, kidney stone pain, the kidney stones themselves, liver disease, diabetic wounds, brain and spinal cord injuries, PTSD, depression, shingles, asthma, ovarian cysts, abdominal adhesions, and scarring all respond to specific frequencies. McMakin explains that results are predictable, reproducible, and teachable—all without side effects—offering hope and healing to millions of people. McMakin tells the story of how thousands of patients with conditions that did not respond to other medical therapies recovered from pain and disability through the non-invasive treatment that she developed. For example, asthma resolves with specific frequencies that remove inflammation, allergy reaction, and spasm from the bronchi. One frequency combination eliminates shingles pain in minutes and stops the shingles attack with a single three-hour treatment. Since 2005, a series of frequencies has been used to treat hundreds of PTSD patients. Post-surgical patients use FSM to reduce pain, prevent bruising, and increase healing. NFL, NHL, and Olympic athletes use it to heal injuries and improve performance. McMakin includes case histories that illustrate the efficacy of the treatment and shares the specific frequencies that each condition requires so that patients direct their own treatments.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive and up-to-date description of the Josephson effect, a topic of never-ending interest in both fundamental and applied physics. In this volume, world-renowned experts present the unique aspects of the physics of the Josephson effect, resulting from the use of new materials, of hybrid architectures and from the possibility of realizing nanoscale junctions. These new experimental capabilities lead to systems where novel coherent phenomena and transport processes emerge. All this is of great relevance and impact, especially when combined with the didactic approach of the book. The reader will benefit from a general and modern view of coherent phenomena in weakly-coupled superconductors on a macroscopic scale. Topics that have been only recently discussed in specialized papers and in short reviews are described here for the first time and organized in a general framework. An important section of the book is also devoted to applications, with focus on long-term, future applications. In addition to a significant number of illustrations, the book includes numerous tables for comparative studies on technical aspects.

Book excerpt: A behavioral scientist explores love, belongingness, and fulfillment, focusing on how modern technology can both help and hinder our need to connect. A Next Big Idea Club nominee. Millions of people around the world are not getting the physical, emotional, and intellectual intimacy they crave. Through the wonders of modern technology, we are connecting with more people more often than ever before, but are these connections what we long for? Pandemic isolation has made us even more alone. In Out of Touch, Professor of Psychology Michelle Drouin investigates what she calls our intimacy famine, exploring love, belongingness, and fulfillment and considering why relationships carried out on technological platforms may leave us starving for physical connection. Drouin puts it this way: when most of our interactions are through social media, we are taking tiny hits of dopamine rather than the huge shots of oxytocin that an intimate in-person relationship would provide. Drouin explains that intimacy is not just sex—although of course sex is an important part of intimacy. But how important? Drouin reports on surveys that millennials (perhaps distracted by constant Tinder-swiping) have less sex than previous generations. She discusses pandemic puppies, professional cuddlers, the importance of touch, “desire discrepancy” in marriage, and the value of friendships. Online dating, she suggests, might give users too many options; and the internet facilitates “infidelity-related behaviors.” Some technological advances will help us develop and maintain intimate relationships—our phones, for example, can be bridges to emotional support. Some, on the other hand, might leave us out of touch. Drouin explores both of these possibilities.

This book was released on 2017-05-02 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book outlines the principles of thermoelectric generation and refrigeration from the discovery of the Seebeck and Peltier effects in the nineteenth century through the introduction of semiconductor thermoelements in the mid-twentieth century to the more recent development of nanostructured materials. It is shown that the efficiency of a thermoelectric generator and the coefficient of performance of a thermoelectric refrigerator can be related to a quantity known as the figure of merit. The figure of merit depends on the Seebeck coefficient and the ratio of the electrical to thermal conductivity. It is shown that expressions for these parameters can be derived from the band theory of solids. The conditions for favourable electronic properties are discussed. The methods for selecting materials with a low lattice thermal conductivity are outlined and the ways in which the scattering of phonons can be enhanced are described. The application of these principles is demonstrated for specific materials including the bismuth telluride alloys, bismuth antimony, alloys based on lead telluride, silicon-germanium and materials described as phonon-glass electron-crystals. It is shown that there can be advantages in using the less familiar transverse thermoelectric effects and the transverse thermomagnetic effects. Finally, practical aspects of thermoelectric generation and refrigeration are discussed. The book is aimed at readers who do not have a specialised knowledge of solid state physics.
