Book Description
Accessible and essential coverage of today's challenging, speculative, cutting-edge science from Quanta Magazine. If you're a science and data nerd like me, you may be interested in "Alice and Bob Meet the Wall of Fire" and "The Prime Number Conspiracy" from Quanta Magazine and Thomas Lin. - Bill Gates These stories reveal the latest efforts to untangle the mysteries of the universe. Bringing together the best and most interesting science stories appearing in Quanta Magazine over the past five years, Alice and Bob Meet the Wall of Fire reports on some of the greatest scientific minds as they test the limits of human knowledge. Quanta, under editor-in-chief Thomas Lin, is the only popular publication that offers in-depth coverage of today's challenging, speculative, cutting-edge science. It communicates science by taking it seriously, wrestling with difficult concepts and clearly explaining them in a way that speaks to our innate curiosity about our world and ourselves. In the title story, Alice and Bob—beloved characters of various thought experiments in physics—grapple with gravitational forces, possible spaghettification, and a massive wall of fire as Alice jumps into a black hole. Another story considers whether the universe is impossible, in light of experimental results at the Large Hadron Collider. We learn about quantum reality and the mystery of quantum entanglement; explore the source of time's arrow; and witness a eureka moment when a quantum physicist exclaims: “Finally, we can understand why a cup of coffee equilibrates in a room.” We reflect on humans' enormous skulls and the Brain Boom; consider the evolutionary benefits of loneliness; peel back the layers of the newest artificial-intelligence algorithms; follow the “battle for the heart and soul of physics”; and mourn the disappearance of the “diphoton bump,” revealed to be a statistical fluctuation rather than a revolutionary new particle. These stories from Quanta give us a front-row seat to scientific discovery. Contributors Philip Ball, K. C.

Pages : 331

Book Description
The Pulitzer Prize–winning magazine’s stories of mathematical explorations show that inspiration strikes haphazardly, revealing surprising solutions and exciting discoveries—with a foreword by James Gleick These stories from Quanta Magazine map the routes of mathematical exploration, showing readers how cutting-edge research is done, while illuminating the productive tension between conjecture and proof, theory and intuition. The stories show that, as James Gleick puts it in the foreword, “inspiration strikes willy-nilly.” One researcher thinks of quantum chaotic systems at a bus stop; another suddenly realizes a path to proving a theorem of number theory while in a friend's backyard; a statistician has a “bathroom sink epiphany” and discovers the key to solving the Gaussian correlation inequality. Readers of The Prime Number Conspiracy, says Quanta editor-in-chief Thomas Lin, are headed on “breathtaking intellectual journeys to the bleeding edge of discovery strapped to the narrative rocket of humanity's never-ending pursuit of knowledge.” Winner of the 2022 Pulitzer Prize for Explanatory Reporting, Quanta is the only popular publication that offers in-depth coverage of the latest breakthroughs in understanding our mathematical universe. It communicates mathematics by taking it seriously, wrestling with difficult concepts and clearly explaining them in a way that speaks to our innate curiosity about our world and ourselves. Readers of this volume will learn that prime numbers have decided preferences about the final digits of the primes that immediately follow them (the “conspiracy” of the title); consider whether math is the universal language of nature (allowing for “a unified theory of randomness”); discover surprising solutions (including a pentagon tiling proof that solves a century-old math problem); ponder the limits of computation; measure infinity; and explore the eternal question “Is mathematics good for you?” Contributors Ariel Bleicher, Robbert Dijkgraaf, Kevin Hartnett, Erica Klarreich, Thomas Lin, John Pavlus, Siobhan Roberts, Natalie Wolchover Copublished with Quanta Magazine

Book Description
“Bob Chapman, CEO of the $1.7 billion manufacturing company Barry-Wehmiller, is on a mission to change the way businesses treat their employees.” – Inc. Magazine Starting in 1997, Bob Chapman and Barry-Wehmiller have pioneered a dramatically different approach to leadership that creates off-the-charts morale, loyalty, creativity, and business performance. The company utterly rejects the idea that employees are simply functions, to be moved around, "managed" with carrots and sticks, or discarded at will. Instead, Barry-Wehmiller manifests the reality that every single person matters, just like in a family. That’s not a cliché on a mission statement; it’s the bedrock of the company’s success. During tough times a family pulls together, makes sacrifices together, and endures short-term pain together. If a parent loses his or her job, a family doesn’t lay off one of the kids. That’s the approach Barry-Wehmiller took when the Great Recession caused revenue to plunge for more than a year. Instead of mass layoffs, they found creative and caring ways to cut costs, such as asking team members to take a month of unpaid leave. As a result, Barry-Wehmiller emerged from the downturn with higher employee morale than ever before. It’s natural to be skeptical when you first hear about this approach. Every time Barry-Wehmiller acquires a company that relied on traditional management practices, the new team members are skeptical too. But they soon learn what it’s like to work at an exceptional workplace where the goal is for everyone to feel trusted and cared for—and where it’s expected that they will justify that trust by caring for each other and putting the common good first. Chapman and coauthor Raj Sisodia show how any organization can reject the traumatic consequences of rolling layoffs, dehumanizing rules, and hypercompetitive cultures. Once you stop treating people like functions or costs, disengaged workers begin to share their gifts and talents toward a shared future. Uninspired workers stop feeling that their jobs have no meaning. Frustrated workers stop taking their bad days out on their spouses and kids. And everyone stops counting the minutes until it’s time to go home. This book chronicles Chapman’s journey to find his true calling, going behind the scenes as his team tackles real-world challenges with caring, empathy, and inspiration. It also provides clear steps to transform your own workplace, whether you lead two people or two hundred thousand. While the Barry-Wehmiller way isn’t easy, it is simple. As the authors put it: "Everyone wants to do better. Trust them. Leaders are everywhere. Find them. People achieve good things, big and small, every day. Celebrate them. Some people wish things were different. Listen to them. Everybody matters. Show them."

Beyond the Dynamical Universe

Beyond the Dynamical Universe PDF Author: Michael Silberstein
Publisher: Oxford University Press
ISBN: 0192533835
Category : Science
Languages : en
Pages : 445

Book Description
Theoretical physics and foundations of physics have not made much progress in the last few decades. Whether we are talking about unifying general relativity and quantum field theory (quantum gravity), explaining so-called dark energy and dark matter (cosmology), or the interpretation and implications of quantum mechanics and relativity, there is no consensus in sight. In addition, both enterprises are deeply puzzled about various facets of time including above all, time as experienced. The authors argue that, across the board, this impasse is the result of the "dynamical universe paradigm," the idea that reality is fundamentally made up of physical entities that evolve in time from some initial state according to dynamical laws. Thus, in the dynamical universe, the initial conditions plus the dynamical laws explain everything else going exclusively forward in time. In cosmology, for example, the initial conditions reside in the Big Bang and the dynamical law is supplied by general relativity. Accordingly, the present state of the universe is explained exclusively by its past. This book offers a completely new paradigm (called Relational Blockworld), whereby the past, present and future co-determine each other via "adynamical global constraints," such as the least action principle. Accordingly, the future is just as important for explaining the present as is the past. Most of the book is devoted to showing how Relational Blockworld resolves many of the current conundrums of both theoretical physics and foundations of physics, including the mystery of time as experienced and how that experience relates to the block universe.

Tough Love

Tough Love PDF Author: Susan Rice
Publisher: Simon and Schuster
ISBN: 1501189999
Category : Biography & Autobiography
Languages : en
Pages : 560

Book Description
Recalling pivotal moments from her dynamic career on the front lines of American diplomacy and foreign policy, Susan E. Rice—National Security Advisor to President Barack Obama and US Ambassador to the United Nations—reveals her surprising story with unflinching candor in this New York Times bestseller. Mother, wife, scholar, diplomat, and fierce champion of American interests and values, Susan Rice powerfully connects the personal and the professional. Taught early, with tough love, how to compete and excel as an African American woman in settings where people of color are few, Susan now shares the wisdom she learned along the way. Laying bare the family struggles that shaped her early life in Washington, DC, she also examines the ancestral legacies that influenced her. Rice’s elders—immigrants on one side and descendants of slaves on the other—had high expectations that each generation would rise. And rise they did, but not without paying it forward—in uniform and in the pulpit, as educators, community leaders, and public servants. Susan too rose rapidly. She served throughout the Clinton administration, becoming one of the nation’s youngest assistant secretaries of state and, later, one of President Obama’s most trusted advisors. Rice provides an insider’s account of some of the most complex issues confronting the United States over three decades, ranging from “Black Hawk Down” in Somalia to the genocide in Rwanda and the East Africa embassy bombings in the late 1990s, and from conflicts in Libya and Syria to the Ebola epidemic, a secret channel to Iran, and the opening to Cuba during the Obama years. With unmatched insight and characteristic bluntness, she reveals previously untold stories behind recent national security challenges, including confrontations with Russia and China, the war against ISIS, the struggle to contain the fallout from Edward Snowden’s NSA leaks, the U.S. response to Russian interference in the 2016 election, and the surreal transition to the Trump administration. Although you might think you know Susan Rice—whose name became synonymous with Benghazi following her Sunday news show appearances after the deadly 2012 terrorist attacks in Libya—now, through these pages, you truly will know her for the first time. Often mischaracterized by both political opponents and champions, Rice emerges as neither a villain nor a victim, but a strong, resilient, compassionate leader. Intimate, sometimes humorous, but always candid, Tough Love makes an urgent appeal to the American public to bridge our dangerous domestic divides in order to preserve our democracy and sustain our global leadership.

Six Impossible Things

Six Impossible Things PDF Author: John Gribbin
Publisher: MIT Press
ISBN: 0262043238
Category : Science
Languages : en
Pages : 104

Book Description
“An elegant and accessible” investigation of quantum mechanics for non-specialists—“highly recommended” for students of the sciences, sci-fi fans, and anyone interested in the strange world of quantum physics (Forbes) Rules of the quantum world seem to say that a cat can be both alive and dead at the same time and a particle can be in two places at once. And that particle is also a wave; everything in the quantum world can described in terms of waves—or entirely in terms of particles. These interpretations were all established by the end of the 1920s, by Erwin Schrödinger, Werner Heisenberg, Paul Dirac, and others. But no one has yet come up with a common sense explanation of what is going on. In this concise and engaging book, astrophysicist John Gribbin offers an overview of six of the leading interpretations of quantum mechanics. Gribbin calls his account “agnostic,” explaining that none of these interpretations is any better—or any worse—than any of the others. Gribbin presents the Copenhagen Interpretation, promoted by Niels Bohr and named by Heisenberg; the Pilot-Wave Interpretation, developed by Louis de Broglie; the Many Worlds Interpretation (termed “excess baggage” by Gribbin); the Decoherence Interpretation (“incoherent”); the Ensemble “Non-Interpretation”; and the Timeless Transactional Interpretation (which theorized waves going both forward and backward in time). All of these interpretations are crazy, Gribbin warns, and some are more crazy than others—but in the quantum world, being more crazy does not necessarily mean more wrong.
