By Steve Gleason, Jeff Duncan. 2024
From NFL player Steve Gleason, a powerful, inspiring memoir of love, heartbreak, resilience, family, and remarkable triumph in the face…
of ALSIn 2011, three years after leaving the NFL, Steve Gleason was diagnosed with ALS, a terminal disease that takes away the ability to move, talk, and breathe. Doctors gave him three years to live. He was thirty-three years old. As Steve says, he is now ten years past his expiration date.His memoir is the chronicle of a remarkable life, one filled with optimism and joy, despite the trauma and pain and despair he has experienced. Writing using eye-tracking technology, Gleason covers his pre-ALS life through the highs and lows of his NFL career with the New Orleans Saints, where he made one of the most memorable plays in Saints history, leading to a victory in the first post-Katrina home game, uplifting the city, making him a hero, and reflected in a nine-foot bronze statue outside the Superdome. Then came his heartbreaking diagnosis. Gleason lost all muscle function, he now uses Stephen Hawking-like technology to communicate, and breathes with the help of a ventilator. This book captures Gleason and his wife Michel&’s unmatched resilience as they reinvent their lives, refuse to succumb to despair, and face his disease realistically and existentially.This unsparing portrait argues that a person's true strength does not reside solely in one&’s body but also in the ability to face unfathomable adversity and still be able to love and treasure life.By Edited by Alice Wong. 2024
The much-anticipated follow up to the groundbreaking anthology Disability Visibility: another revolutionary collection of first-person writing on the joys and…
challenges of the modern disability experience, and intimacy in all its myriad forms.What is intimacy? More than sex, more than romantic love, the pieces in this stunning and illuminating new anthology offer broader and more inclusive definitions of what it can mean to be intimate with another person. Explorations of caregiving, community, access, and friendship offer us alternative ways of thinking about the connections we form with others—a vital reimagining in an era when forced physical distance is at times a necessary norm. But don't worry: there's still sex to consider—and the numerous ways sexual liberation intersects with disability justice. Plunge between these pages and you'll also find disabled sexual discovery, disabled love stories, and disabled joy. These twenty-five stunning original pieces—plus other modern classics on the subject, all carefully curated by acclaimed activist Alice Wong—include essays, photo essays, poetry, drama, and erotica: a full spectrum of the dreams, fantasies, and deeply personal realities of a wide range of beautiful bodies and minds. Disability Intimacy will free your thinking, invigorate your spirit, and delight your desires.By Jeremiah P. Ostriker, Simon Mitton. 2013
Humanity's ongoing quest to unlock the secrets of dark matter and dark energyHeart of Darkness describes the incredible saga of…
humankind's quest to unravel the deepest secrets of the universe. Over the past forty years, scientists have learned that two little-understood components—dark matter and dark energy—comprise most of the known cosmos, explain the growth of all cosmic structure, and hold the key to the universe's fate. The story of how evidence for the so-called "Lambda-Cold Dark Matter" model of cosmology has been gathered by generations of scientists throughout the world is told here by one of the pioneers of the field, Jeremiah Ostriker, and his coauthor Simon Mitton.From humankind's early attempts to comprehend Earth's place in the solar system, to astronomers' exploration of the Milky Way galaxy and the realm of the nebulae beyond, to the detection of the primordial fluctuations of energy from which all subsequent structure developed, this book explains the physics and the history of how the current model of our universe arose and has passed every test hurled at it by the skeptics. Throughout this rich story, an essential theme is emphasized: how three aspects of rational inquiry—the application of direct measurement and observation, the introduction of mathematical modeling, and the requirement that hypotheses should be testable and verifiable—guide scientific progress and underpin our modern cosmological paradigm.This monumental puzzle is far from complete, however, as scientists confront the mysteries of the ultimate causes of cosmic structure formation and the real nature and origin of dark matter and dark energy.Dans Avantages il n’y a que…des avantages !

This Second Edition is a comprehensive update, integrating the latest research and theoretical advancements in the field of de Sitter…
(dS) group representations. Building on the success of the first edition, the book offers a more in-depth analysis of mathematical aspects, conceptual foundations, and practical implications related to the dS group, including its Lie manifold, Lie algebra, and co-adjoint orbits, viewing the latter as potential classical elementary systems within the context of dS spacetime. Additionally, the examination of unitary irreducible representations (UIRs) sheds light on the potential existence of quantum elementary systems within the dS spacetime framework. The authors emphasize consistency with Wigner's approach to elementary systems, incorporate Wigner's principles and exploring projective UIRs of the dS group, and provide a deeper insight into the nature of dS elementary systems. Particular attention is paid to: the “smooth” transition from classical to quantum theory, the physical content under vanishing curvature, and the thermal interpretation from a quantum perspective. The book also focuses on the physical interpretation of elementary systems in curved spacetimes, recognizing the limitations of traditional concepts derived from flat Minkowski spacetime and the Poincaré group.By Shishir Kumar Shandilya, Agni Datta, Yash Kartik, Atulya Nagar. 2024

Classical Electrodynamics captures Schwinger's inimitable lecturing style, in which everything flows inexorably from what has gone before. This anniversary edition…
offers a refreshing update while still maintaining Schwinger’s voice.The book provides the student with a thorough grounding in electrodynamics in particular, and in classical field theory in general. An essential resource for both physicists and their students, the book includes a Reader's Guide, which describes the major themes in each chapter, suggests a possible path through the book, and identifies topics for inclusion in, and exclusion from, a given course, depending on the instructor's preference.Carefully constructed problems complement the material of the text. Classical Electrodynamics should be of great value to all physicists, from first-year graduate students to senior researchers, and to all those interested in electrodynamics, field theory, and mathematical physics.The original text for the graduate classical electrodynamics course was left unfinished upon Julian Schwinger's death in 1994, but was completed by his former students and co-authors, who have brilliantly recreated the excitement of Schwinger's novel approach. This anniversary edition has been revised by one of those original co-authors, Kimball Milton.By Pankaj Jain. 2024
Astronomy is the field of science devoted to the study of astronomical objects, such as stars, galaxies, and nebulae. Astronomers…
have gathered a wealth of knowledge about the universe through hundreds of years of painstaking observations.

not be a philosopher or a botanist, and certainly not a mathematician, to enjoy the bounty of the world around us. But is there some sort of order, a pattern, to the things that we see in the sky, on the ground, at the beach? In A Beginner's Guide to Constructing the Universe, Michael Schneider, an education writer and computer consultant, combines science, philosophy, art, and common sense to reaffirm what the ancients observed: that a consistent language of geometric design underpins every level of the universe, from atoms to galaxies, cucumbers to cathedrals. Schneider also discusses numerical and geometric symbolism through the ages, and concepts such as periodic renewal and resonance. This book is an education in the world and everything we can't see within it.Contains numerous b&w photos and illustrations.Depuis plus de soixante ans, chaque semaine, dans ELLE, les femmes s’informent sur l’actualité, les tendances, la mode, la beauté.…

This book provides an advanced introduction to extended theories of quantum field theory and algebraic topology, including Hamiltonian quantization associated…
with some geometrical constraints, symplectic embedding and Hamilton-Jacobi quantization and Becchi-Rouet-Stora-Tyutin (BRST) symmetry, as well as de Rham cohomology. This extended new edition offers a multifaced insight into phenomenology of particles such as baryons and photons, in terms of extended objects. In particular, in the second edition, the baryons are described in hypersphere soliton model, and the photon properties are additionally included in stringy photon model and in Dirac type relativistic quantum mechanics for a photon.It offers a critical overview of the research in this area and unifies the existing literatures, employing a consistent notation. Although the results presented apply in principle to all alternative quantization schemes, special emphasis is placed on the BRST quantization and its de Rham cohomology group which contribute to a deep understanding of constrained physical theories. The book describes how solitons and other models subject to constraints include rigorous treatments of the geometrical constraints which affect the predictions themselves. The book is intended for use by any graduate-level student with quantum field and relativity theories, and it also serves as a useful reference for those working in the field. An extensive bibliography guides the reader toward the source literature on particular topics.This book offers a comprehensive collection of introductory experiments in nuclear and cosmic ray physics utilizing Geiger counters. It features…

Passages and Knocking on Heaven’s Door uses her research into dark matter to illuminate the startling connections between the furthest reaches of space and life here on Earth.Sixty-six million years ago, an object the size of a city descended from space to crash into Earth, creating a devastating cataclysm that killed off the dinosaurs, along with three-quarters of the other species on the planet. What was its origin? In Dark Matter and the Dinosaurs, Lisa Randall proposes it was a comet that was dislodged from its orbit as the Solar System passed through a disk of dark matter embedded in the Milky Way. In a sense, it might have been dark matter that killed the dinosaurs.Working through the background and consequences of this proposal, Randall shares with us the latest findings—established and speculative—regarding the nature and role of dark matter and the origin of the Universe, our galaxy, our Solar System, and life, along with the process by which scientists explore new concepts. In Dark Matter and the Dinosaurs, Randall tells a breathtaking story that weaves together the cosmos’ history and our own, illuminating the deep relationships that are critical to our world and the astonishing beauty inherent in the most familiar things.
