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.

Book Description
Actors and Audiences explores the exchanges between those on and off the stage that fill the atmosphere with energy and vitality. Caroline Heim utilises the concept of "electric air" to describe this phenomenon and discuss the charge of emotional electricity that heightens the audience's senses in the theatre. In order to understand this electric air, Heim draws from in-depth interviews with 79 professional audience members and 22 international stage and screen actors in the United Kingdom, United States, France and Germany. Tapping into the growing interest in empirical studies of the audience, this book documents experiences from three productions - The Encounter, Heisenberg and Hunger. Peer Gynt - to describe the nature of these conversations. The interviews disclose essential elements: transference, identification, projection, double consciousness, presence, stage fright and the suspension of disbelief. Ultimately Heim reveals that the heart of theatre is the relationship between those on- and off-stage, the way in which emotions and words create psychological conversations that pass through the fourth wall into an "in-between space," and the resulting electric air. A fascinating introduction to a unique subject, this book provides a close examination of actor and audience perspectives, which is essential reading for students and academics of Theatre, Performance and Audience Studies.

Book Description
Where would we be without conversation? Throughout history, conversations have allowed us to see different perspectives, build ideas, and solve problems. Conversations, particularly those referred to in this book as academic conversations, push students to think and learn in lasting ways. Academic conversations are back-and-forth dialogues in which students focus on a topic and explore it by building, challenging, and negotiating relevant ideas. Unfortunately, academic conversations are rare in many classrooms. Talk is often dominated by the teacher and a few students, or it does not advance beyond short responses to the teacher's questions. Even certain teaching approaches and curriculum programs neglect to train students how to maintain a focused, respectful, and thoughtful conversation. To address these challenges, authors Jeff Zwiers and Marie Crawford have identified five core communication skills to help students hold productive academic conversations across content areas. These skills include: elaborating and clarifying, supporting ideas with evidence, building on and/or challenging ideas, paraphrasing, and synthesizing. This book shows teachers how to weave the cultivation of academic conversation skills and conversations into current teaching approaches. More specifically, it describes how to use conversations to build the following: Academic vocabulary and grammar Critical thinking skills such as persuasion, interpretation, consideration of multiple perspectives, evaluation, and application Literacy skills such as questioning, predicting, connecting to prior knowledge, and summarizing Complex and abstract essential understandings in content areas such as adaptation, human nature, bias, conservation of mass, energy, gravity, irony, democracy, greed, and more An academic classroom environment brimming with respect for others' ideas, equity of voice, engagement, and mutual support The ideas in this book stem from many hours of classroom practice, research, and video analysis across grade levels and content areas. Readers will find numerous practical activities for working on each conversation skill, crafting conversation-worthy tasks, and using conversations to teach and assess. Academic Conversations offers an in-depth approach to helping students develop into the future parents, teachers, and leaders who will collaborate to build a better world.

Book Description
The idea that the digital age has revolutionized our day-to-day experience of the world is nothing new, and has been amply recognized by cultural historians. In contrast, Stephen Robertson's BC: Before Computers is a work which questions the idea that the mid-twentieth century saw a single moment of rupture. It is about all the things that we had to learn, invent, and understand - all the ways we had to evolve our thinking - before we could enter the information technology revolution of the second half of the twentieth century. Its focus ranges from the beginnings of data processing, right back to such originary forms of human technology as the development of writing systems, gathering a whole history of revolutionary moments in the development of information technologies into a single, although not linear narrative. Treading the line between philosophy and technical history, Robertson draws on his extensive technical knowledge to produce a text which is both thought-provoking and accessible to a wide range of readers. The book is wide in scope, exploring the development of technologies in such diverse areas as cryptography, visual art and music, and the postal system. Through all this, it does not simply aim to tell the story of computer developments but to show that those developments rely on a long history of humans creating technologies for increasingly sophisticated methods of manipulating information. Through a clear structure and engaging style, it brings together a wealth of informative and conceptual explorations into the history of human technologies, and avoids assumptions about any prior knowledge on the part of the reader. As such the expert and the general reader alike will find it of interest.

Book Description
NATIONAL BESTSELLER • A “beautiful and eye-opening” (Jacqueline Woodson), “hilarious and heart-rending” (Celeste Ng) graphic memoir about American identity, interracial families, and the realities that divide us, from the acclaimed author of The Sleepwalker’s Guide to Dancing. ONE OF THE TEN BEST BOOKS OF THE YEAR: Chicago Tribune, The New York Public Library, Publishers Weekly • ONE OF THE BEST BOOKS OF THE YEAR: The New York Times Book Review, Time, BuzzFeed, Esquire, Literary Journal, Kirkus Reviews “How brown is too brown?” “Can Indians be racist?” “What does real love between really different people look like?” Like many six-year-olds, Mira Jacob’s half-Jewish, half-Indian son, Z, has questions about everything. At first they are innocuous enough, but as tensions from the 2016 election spread from the media into his own family, they become much, much more complicated. Trying to answer him honestly, Mira has to think back to where she’s gotten her own answers: her most formative conversations about race, color, sexuality, and, of course, love. Written with humor and vulnerability, this deeply relatable graphic memoir is a love letter to the art of conversation—and to the hope that hovers in our most difficult questions. LONGLISTED FOR THE PEN/OPEN BOOK AWARD “Jacob’s earnest recollections are often heartbreaking, but also infused with levity and humor. What stands out most is the fierce compassion with which she parses the complexities of family and love.”—Time “Good Talk uses a masterful mix of pictures and words to speak on life’s most uncomfortable conversations.”—io9 “Mira Jacob just made me toss everything I thought was possible in a book-as-art-object into the garbage. Her new book changes everything.”—Kiese Laymon, New York Times bestselling author of Heavy

Book Description
Explores how even small changes in the way we talk with one another can produce extraordinarily positive outcomes. Describes how to get maximum results from four types of conversations we use every day Research-based and practical, with sample dialogues and personal stories that show how to put the four conversations into practice Talk is powerful. Engaging in the right conversation at the right time is key to both personal and organizational success. And it isn't just difficult' conversations that matter. The Four Conversations clearly demonstrates it is the everyday dialogue we have with one another that is critical. Armed with a solid body of research and their own first-hand observations, Jeffrey and Laurie Ford identify four types of conversations that every one of us must use to get things done; initiative conversations to introduce something new; understanding conversations to help people relate to new ideas or processes; performance conversations to request specific actions and results; and closure conversations to complete work and give people a sense of accomplishment . They identify the specific elements that make each of these conversations successful and show how they can be put together in different ways to achieve different objectives. The Four Conversations demonstrates how to use the right conversation at the right time - planning and starting each one well, and finishing every conversation effectively - to produce the results we want and the improved productivity our organizations need. And through dozens of personal stories and sample dialogues, the authors illustrate how real people in real situations have used the four conversations, either alone or in combination, to more effectively combat common workplace problems and lay the foundations for enduring success; stronger relationships, better buy-in, and a greater feeling of personal and professional achievement for everyone.
