One Wave at a Time


Book Description

After his father dies, Kai experiences all kinds of emotions: sadness, anger, fear, guilt. Sometimes they crash and mix together. Other times, there are no emotions at all—just flatness. As Kai and his family adjust to life without Dad, the waves still roll in. But with the help of friends and one another, they learn to cope—and, eventually, heal. A lyrical story about grieving for anyone encountering loss.




Wave Propagation and Time Reversal in Randomly Layered Media


Book Description

The content of this book is multidisciplinary by nature. It uses mathematical tools from the theories of probability and stochastic processes, partial differential equations, and asymptotic analysis, combined with the physics of wave propagation and modeling of time reversal experiments. It is addressed to a wide audience of graduate students and researchers interested in the intriguing phenomena related to waves propagating in random media. At the end of each chapter there is a section of notes where the authors give references and additional comments on the various results presented in the chapter.




In Time's Rift (Im Zeitspalt)


Book Description

“In a rift of time the corner of the universe appears to consciousness.” —Ernst Meister




Plane-Wave Theory of Time-Domain Fields


Book Description

"This invaluable book provides a comprehensive framework for the formulation and solution ofnumerous problems involving the radiation, reception, propagation, and scattering of electromagnetic and acoustic waves. Filled with original derivations and theorems, it includes the first rigorous development of plane-wave expansions for time-domain electromagnetic and acoustic fields. For the past 35 years, near-field measurement techniques have been confined to the frequency domain. Now, with the publication of this book, probe-corrected near-field measurement techniques have been extended to ultra-wide-band, short-pulse transmitting and receiving antennas and transducers. By combining unencumbered straightforward derivations with in-depth expositions of prerequisite material, the authors have created an invaluable resource for research scientists and engineers in electromagnetics and acoustics, and a definitive reference on plane-wave expansions and near-field measurements. Featured topics include: * An introduction to the basic electromagnetic and acoustic field equations * A rigorous development of time-domain and frequency-domain plane-wave representations * The formulation of time-domain, frequency-domain, and static planar near-field measurement techniques with and without probe-correction * Sampling theorems and computation schemes for time-domain and frequency-domain fields * Analytic-signal formulas that simplify the formulation and analysis of transient fields * Wave phenomena, such as ``electromagnetic missiles"" encountered only in the time domain * Definitive force and power relations for electromagnetic and acoustic fields and sources."

Guard The Mysteries


Book Description

Guard the Mysteries is a compendium of five talks that the poet Cedar Sigo presented for the Bagley Wright Lecture series. Retracing the ways in which he first encountered the realm of poetry, Sigo plumbs the particulars of modern critique, identity politics, early influences, and poetic form to produce a singular ‘autobiography of voice.’ Across these lectures, Sigo explores his childhood on the Suquamish Reservation, while paying homage to revolutionary artists, teachers, and thinkers whom have shaped his poetic aesthetic. Simultaneously timeless and extremely timely, these talks ponder the presences that California Buddhism, LGBTQ+ experiences, and Native Nations occupy in the poetic world and the world at large.




The Perfect Wave


Book Description

Almost weightless and able to pass through the densest materials with ease, neutrinos may offer answers to questions ranging from relativity and quantum mechanics to more radical theories about dark energy and supersymmetry. Heinrich Päs serves as our fluent guide to a particle world that tests the boundaries of space, time, and human knowledge.




The Topology of 4-Manifolds


Book Description

This book presents the classical theorems about simply connected smooth 4-manifolds: intersection forms and homotopy type, oriented and spin bordism, the index theorem, Wall's diffeomorphisms and h-cobordism, and Rohlin's theorem. Most of the proofs are new or are returbishings of post proofs; all are geometric and make us of handlebody theory. There is a new proof of Rohlin's theorem using spin structures. There is an introduction to Casson handles and Freedman's work including a chapter of unpublished proofs on exotic R4's. The reader needs an understanding of smooth manifolds and characteristic classes in low dimensions. The book should be useful to beginning researchers in 4-manifolds.




The Wave Equation on a Curved Space-Time


Book Description

This book gives a rigourous discussion of the local effects of curvature on the behaviour of waves. In the course of this discussion many techniques are developed which are also needed for a study of more general problems, in which the gravitational field itself plays a dynamical role.




Time Travels


Book Description

Recently the distinguished feminist theorist Elizabeth Grosz has turned her critical acumen toward rethinking time and duration. Time Travels brings her trailblazing essays together to show how reconceptualizing temporality transforms and revitalizes key scholarly and political projects. In these essays, Grosz demonstrates how imagining different relations between the past, present, and future alters understandings of social and scientific projects ranging from theories of justice to evolutionary biology, and she explores the radical implications of the reordering of these projects for feminist, queer, and critical race theories. Grosz’s reflections on how rethinking time might generate new understandings of nature, culture, subjectivity, and politics are wide ranging. She moves from a compelling argument that Charles Darwin’s notion of biological and cultural evolution can potentially benefit feminist, queer, and antiracist agendas to an exploration of modern jurisprudence’s reliance on the notion that justice is only immanent in the future and thus is always beyond reach. She examines Henri Bergson’s philosophy of duration in light of the writings of Gilles Deleuze, Maurice Merleau-Ponty, and William James, and she discusses issues of sexual difference, identity, pleasure, and desire in relation to the thought of Deleuze, Friedrich Nietzsche, Michel Foucault, and Luce Irigaray. Together these essays demonstrate the broad scope and applicability of Grosz’s thinking about time as an undertheorized but uniquely productive force.
