A world-renowned physicist seeks gravity’s true nature and finds wisdom in embracing its force in her lifeClaudia de Rham has been playing with gravity her entire life. As a diver, experimenting with her body’s buoyancy in the Indian Ocean. As a pilot, soaring over Canadian waterfalls on dark mornings before beginning her daily scientific research. As an astronaut candidate, dreaming of the experience of flying free from Earth’s pull. And as a physicist, discovering new sides to gravity’s irresistible personality by exploring the limits of Einstein’s general theory of relativity. In The Beauty of Falling, de Rham shares captivating stories about her quest to gain intimacy with gravity, to understand both its feeling and fundamental nature. Her life’s pursuit led her from a twist of fate that snatched away her dream of becoming an astronaut to an exhilarating breakthrough at the very frontiers of gravitational physics.While many of us presume to know gravity quite well, the brightest scientists in history have yet to fully answer the simple question: what exactly is gravity? De Rham reveals how great minds—from Newton and Einstein to Stephen Hawking, Andrea Ghez, and Roger Penrose—led her to the edge of knowledge about this fundamental force. She found hints of a hidden side to gravity at the particle level where Einstein’s theory breaks down, leading her to develop a new theory of “massive gravity.” De Rham shares how her life’s path turned from a precipitous fall to an exquisite flight toward the discovery of something entirely new about our surprising, gravity-driven universe.

Wilfred’s pioneering and strangely prescient musical instrument predates television, video art and psychedeliaInventor, designer, artist and musician Thomas Wilfred (1889–1968) devoted his life to the creation of a new art form—"Lumia," or the art of light. He invented his own version of a color organ (a term he disliked) and dubbed it the Clavilux, from the Latin meaning "light played by key." After a successful international tour in the 1920s, Wilfred reinvented these large-scale performances as self-enclosed light shows for domestic entertainment. While they enjoyed a short commercial life, Wilfred’s aesthetically elegant and interactive Clavilux and Lumia home models soon found their way into storied collections. His work was included in the Museum of Modern Art’s 1952 exhibition 15 Americans, where it was seen by many artists who would work with light as their medium in the 1960s and ’70s.Clavilux and Lumia Home Models presents a stimulating collection of archival material culled from the Wilfred archive at Yale University and other sources, including Wilfred’s never-before-published sketches.

In this age of superstring theories and Big Bang cosmology, we're used to thinking of the unknown as impossibly distant from our everyday lives. But in A Different Universe , Nobel Laureate Robert Laughlin argues that the scientific frontier is right under our fingers. Instead of looking for ultimate theories, Laughlin considers the world of emergent properties-meaning the properties, such as the hardness and shape of a crystal, that result from the organization of large numbers of atoms. Laughlin shows us how the most fundamental laws of physics are in fact emergent. A Different Universe is a truly mind-bending book that shows us why everything we think about fundamental physical laws needs to change.

This self-contained textbook with exercises discusses a broad range of selected topics from classical mechanics and electromagnetic theory that inform key issues related to modern accelerators.Part I presents fundamentals of the Lagrangian and Hamiltonian formalism for mechanical systems, canonical transformations, action-angle variables, and then linear and nonlinear oscillators. The Hamiltonian for a circular accelerator is used to evaluate the equations of motion, the action, and betatron oscillations in an accelerator.  From this base, we explore the impact of field errors and nonlinear resonances.  This part ends with the concept of the distribution function and an introduction to the kinetic equation to describe large ensembles of charged particles and to supplement the previous single-particle analysis of beam dynamics.Part II focuses on classical electromagnetism and begins with an analysis of the electromagnetic field from relativistic beams, both in vacuum and in a resistive pipe.  Plane electromagnetic waves and modes in waveguides and radio-frequency cavities are also discussed.  The focus then turns to radiation processes of relativistic beams in different conditions, including transition, diffraction, synchrotron, and undulator radiation. Fundamental concepts such as the retarded time for the observed field from a charged particle, coherent and incoherent radiation, and the formation length of radiation are introduced. We conclude with a discussion of laser-driven acceleration of charged particles and the radiation damping effect.Appendices on electromagnetism and special relativity are included, and references are given in some chapters as a launching point for further reading.This text is intended for graduate students who are beginning to explore the field of accelerator physics, but is also recommended for those who are familiar with particle accelerators but wish to delve further intothe theory underlying some of the more pressing concerns in their design and operation.

This book is a gentle introduction for all those wishing to learn about modern views of the cosmos. Our universe originated in a great explosion – the big bang. For nearly a century cosmologists have studied the aftermath of this explosion: how the universe expanded and cooled down, and how galaxies were gradually assembled by gravity. The nature of the bang itself has come into focus only relatively recently. It is the subject of the theory of cosmic inflation, which was developed in the last few decades and has led to a radically new global view of the universe.Students and other interested readers will find here a non-technical but conceptually rigorous account of modern cosmological ideas - describing what we know, and how we know it. One of the book's central themes is the scientific quest to find answers to the ultimate cosmic questions: Is the universe finite or infinite? Has it existed forever? If not, when and how did it come into being? Will it ever end?The book is based on the undergraduate course taught by Alex Vilenkin at Tufts University. It assumes no prior knowledge of physics or mathematics beyond elementary high school math. The necessary physics background is introduced as it is required. Each chapter includes a list of questions and exercises of varying degree of difficulty. This new edition includes hints for answering the questions and exercises, as well as extensions to the discussions on dark matter, quantum cosmology. A new chapter summarizing the standard cosmological model has also been added.
