Conversations on Electric and Magnetic Fields in the Cosmos
Author: Eugene N. ParkerPublisher: Princeton University Press

Pages : 196
Book Description
Today's standard textbooks treat the theoretical structure of electric and magnetic fields, but their emphasis is on electromagnetic radiation and static-electric and magnetic fields. In this book, Eugene Parker provides advanced graduate students and researchers with a much-needed complement to existing texts, one that discusses the dynamic electromagnetism of the cosmos--that is, the vast magnetic fields that are carried bodily in the swirling ionized gases of stars and galaxies and throughout intergalactic space. Parker is arguably the world's leading authority on solar wind and the effects of magnetic fields in the heliosphere, and his originality of thought and distinctive approach to physics are very much in evidence here. Seeking to enrich discussions in standard texts and correct misconceptions about the dynamics of these large-scale fields, Parker engages readers in a series of "conversations" that are at times anecdotal and even entertaining without ever sacrificing theoretical rigor. The dynamics he describes represents the Maxwell stresses of the magnetic field working against the pressure and inertia of the bulk motion of ionized gases, characterized in terms of the magnetic field and gas velocity. Parker shows how this dynamic interaction cannot be fully expressed in terms of the electric current and electric field. Conversations on Electric and Magnetic Fields in the Cosmos goes back to basics to explain why classical hydrodynamics and magnetohydrodynamics are inescapable, even in the deepest reaches of space.
The Electricity of Every Living Thing
Author: Katherine MayPublisher: Melville House
ISBN: 1612199607
Category : Body, Mind & Spirit
Languages : en
Pages : 305
Book Description
The New York Times bestselling author of Wintering writes a life-affirming exploration of wild landscapes, what it means to be different and, above all, how we can all learn to make peace with our own unquiet minds . . . In anticipation of her 38th birthday, Katherine May set out to walk the 630-mile South West Coast Path. She wanted time alone, in nature, to understand why she had stopped coping with everyday life; why motherhood had been so overwhelming and isolating; and why the world felt full of expectations she couldn't meet. She was also reeling from a chance encounter with a voice on the radio that sparked her realisation that she might be autistic. And so begins a trek along the ruggedly beautiful but difficult path by the sea that takes readers through the alternatingly frustrating, funny, and enlightening experience of re-awakening to the world around us… The Electricity of Every Living Thing sees Katherine come to terms with that diagnosis leading her to re-evaluate her life so far — with a much kinder, more forgiving eye. We bear witness to a new understanding that finally allows her to be different rather than simply awkward, arrogant or unfeeling. The physical and psychological journeys of this joyous and inspiring book become inextricably entwined, and as Katherine finds her way across the untameable coast, we learn alongside her how to find our way back to our own true selves.

Book Description
Conversation-powered leadership How can leaders make their big or growing companies feel small again? How can they recapture the “magic”—the tight strategic alignment, the high level of employee engagement—that drove and animated their organization when it was a start-up? As more and more executives have discovered in recent years, the answer to this conundrum lies in the power of conversation. In Talk, Inc., Boris Groysberg and Michael Slind show how trusted and effective leaders are adapting the principles of face-to-face conversation in order to pursue a new form of organizational conversation. They explore the promise of conversation-powered leadership—from the time-tested practice of talking straight (and listening well) to the thoughtful adoption of social media technology. And they offer guidance on how to balance the benefits of open-ended talk with the realities of strategic execution. Drawing on the experience of leaders at diverse companies from around the world, Talk, Inc., offers provocative insights and user-friendly tips on how to make organizational culture more intimate, more interactive, more inclusive, and more intentional—in short, more conversational.
Energy and Civilization

Pages : 564
Book Description
A comprehensive account of how energy has shaped society throughout history, from pre-agricultural foraging societies through today's fossil fuel–driven civilization. "I wait for new Smil books the way some people wait for the next 'Star Wars' movie. In his latest book, Energy and Civilization: A History, he goes deep and broad to explain how innovations in humans' ability to turn energy into heat, light, and motion have been a driving force behind our cultural and economic progress over the past 10,000 years. —Bill Gates, Gates Notes, Best Books of the Year Energy is the only universal currency; it is necessary for getting anything done. The conversion of energy on Earth ranges from terra-forming forces of plate tectonics to cumulative erosive effects of raindrops. Life on Earth depends on the photosynthetic conversion of solar energy into plant biomass. Humans have come to rely on many more energy flows—ranging from fossil fuels to photovoltaic generation of electricity—for their civilized existence. In this monumental history, Vaclav Smil provides a comprehensive account of how energy has shaped society, from pre-agricultural foraging societies through today's fossil fuel–driven civilization. Humans are the only species that can systematically harness energies outside their bodies, using the power of their intellect and an enormous variety of artifacts—from the simplest tools to internal combustion engines and nuclear reactors. The epochal transition to fossil fuels affected everything: agriculture, industry, transportation, weapons, communication, economics, urbanization, quality of life, politics, and the environment. Smil describes humanity's energy eras in panoramic and interdisciplinary fashion, offering readers a magisterial overview. This book is an extensively updated and expanded version of Smil's Energy in World History (1994). Smil has incorporated an enormous amount of new material, reflecting the dramatic developments in energy studies over the last two decades and his own research over that time.

The Moral Case for Fossil Fuels
Author: Alex EpsteinPublisher: Penguin
ISBN: 0698175484
Category : Business & Economics
Languages : en
Pages : 257
Book Description
Could everything we know about fossil fuels be wrong? For decades, environmentalists have told us that using fossil fuels is a self-destructive addiction that will destroy our planet. Yet at the same time, by every measure of human well-being, from life expectancy to clean water to climate safety, life has been getting better and better. How can this be? The explanation, energy expert Alex Epstein argues in The Moral Case for Fossil Fuels, is that we usually hear only one side of the story. We’re taught to think only of the negatives of fossil fuels, their risks and side effects, but not their positives—their unique ability to provide cheap, reliable energy for a world of seven billion people. And the moral significance of cheap, reliable energy, Epstein argues, is woefully underrated. Energy is our ability to improve every single aspect of life, whether economic or environmental. If we look at the big picture of fossil fuels compared with the alternatives, the overall impact of using fossil fuels is to make the world a far better place. We are morally obligated to use more fossil fuels for the sake of our economy and our environment. Drawing on original insights and cutting-edge research, Epstein argues that most of what we hear about fossil fuels is a myth. For instance . . . Myth: Fossil fuels are dirty. Truth: The environmental benefits of using fossil fuels far outweigh the risks. Fossil fuels don’t take a naturally clean environment and make it dirty; they take a naturally dirty environment and make it clean. They don’t take a naturally safe climate and make it dangerous; they take a naturally dangerous climate and make it ever safer. Myth: Fossil fuels are unsustainable, so we should strive to use “renewable” solar and wind. Truth: The sun and wind are intermittent, unreliable fuels that always need backup from a reliable source of energy—usually fossil fuels. There are huge amounts of fossil fuels left, and we have plenty of time to find something cheaper. Myth: Fossil fuels are hurting the developing world. Truth: Fossil fuels are the key to improving the quality of life for billions of people in the developing world. If we withhold them, access to clean water plummets, critical medical machines like incubators become impossible to operate, and life expectancy drops significantly. Calls to “get off fossil fuels” are calls to degrade the lives of innocent people who merely want the same opportunities we enjoy in the West. Taking everything into account, including the facts about climate change, Epstein argues that “fossil fuels are easy to misunderstand and demonize, but they are absolutely good to use. And they absolutely need to be championed. . . . Mankind’s use of fossil fuels is supremely virtuous—because human life is the standard of value and because using fossil fuels transforms our environment to make it wonderful for human life.”
