In this title, Michael Morgan explains how our brain interprets the images that the outside world forms in our eyes. Using sources from over the centuries - philosophical writings, scientific thinking, experiments, passages from poems, novels and films - Morgan reveals the problems that the brain has to confront in manufacturing our perceptions. The book includes optical drawings as well as some simple experiments that the reader can do to test the different components of one's sight and our own reactions to it. There is a long way to go in neurological terms before we can understand how our brains actually see, or indeed the precise location of where this happens inside the grey matter. Morgan recognizes that to achieve such an understanding may even necessitate the development of a new language that can better encompass the difficult scientific and logical interpretations that will have to be made. This work provides an overview of what we know about how the brain works regarding visual space, giving an insight into one of our most vital yet least understood senses.

Millions of Americans experience some degree of hearing loss. The Social Security Administration (SSA) operates programs that provide cash disability benefits to people with permanent impairments like hearing loss, if they can show that their impairments meet stringent SSA criteria and their earnings are below an SSA threshold. The National Research Council convened an expert committee at the request of the SSA to study the issues related to disability determination for people with hearing loss. This volume is the product of that study. Hearing Loss: Determining Eligibility for Social Security Benefits reviews current knowledge about hearing loss and its measurement and treatment, and provides an evaluation of the strengths and weaknesses of the current processes and criteria. It recommends changes to strengthen the disability determination process and ensure its reliability and fairness. The book addresses criteria for selection of pure tone and speech tests, guidelines for test administration, testing of hearing in noise, special issues related to testing children, and the difficulty of predicting work capacity from clinical hearing test results. It should be useful to audiologists, otolaryngologists, disability advocates, and others who are concerned with people who have hearing loss.

“To hear silence is to find stillness in the midst of the restlessness that makes creative life possible and the inescapability of death acceptable.” So writes Mark C. Taylor in his latest book, a philosophy of silence for our nervous, chattering age. How do we find silence—and more importantly, how do we understand it—amid the incessant buzz of the networks that enmesh us? Have we forgotten how to listen to each other, to recognize the virtues of modesty and reticence, and to appreciate the resonance of silence? Are we less prepared than ever for the ultimate silence that awaits us all? Taylor wants us to pause long enough to hear what is not said and to attend to what remains unsayable. In his account, our way to hearing silence is, paradoxically, to see it. He explores the many variations of silence by considering the work of leading modern and postmodern visual artists, including Barnett Newman, Ad Reinhardt, James Turrell, and Anish Kapoor. Developing the insights of philosophers, theologians, writers, and composers, Taylor weaves a rich narrative modeled on the Stations of the Cross. His chapter titles suggest our positions toward silence: Without. Before. From. Beyond. Against. Within. Between. Toward. Around. With. In. Recasting Hegel’s phenomenology of spirit and Kierkegaard’s stages on life’s way, Taylor translates the traditional Via Dolorosa into a Nietzschean Via Jubilosa that affirms light in the midst of darkness. Seeing Silence is a thoughtful meditation that invites readers to linger long enough to see silence, and, in this way, perhaps to hear once again the wordless Word that once was named “God.”

Discusses the sense of hearing, and how the ear works to interpret sound, includes simple experiments to investigate hearing.

A Fareed Zakaria GPS Book of the Week: “An exhilarating look at the cutting edge of bioengineering. . . . a mind-bending read.” —Kirkus Reviews (starred review) For millennia, humans have tried—and often failed—to master nature and transcend our limits. But this has started to change. The new scientific frontier is the human body: The greatest engineers of our generation have turned their sights inward, and their work is beginning to revolutionize mankind. In The Body Builders, Adam Piore takes us on a fascinating journey into the field of bioengineering—which can be used to reverse engineer, rebuild, and augment human beings—and paints a vivid portrait of the people at its center. Chronicling the ways new technology has retooled our physical expectations and mental processes, Piore visits people who have regrown parts of their fingers and legs in the wake of terrible traumas; tries on a muscle suit that allows him to lift ninety pounds with his fingertips; dips into the race to create “Viagra for the brain”; and shadows the doctors trying to give mute patients the ability to communicate telepathically. As science continues to lay bare the mysteries of human performance, it is helping us to see—and exist—above our expectations. The Body Builders goes beyond the headlines and the hype to reveal the inner workings and the outer reaches of our bodies and minds, and explore how new developments are changing, and will forever change, what is possible for humankind. Weaving powerful storytelling with groundbreaking science, The Body Builders explores the current revolution in human augmentation, which is helping us triumph over the limitations and constraints we’ve long accepted as an inevitable part of being human. “Piore writes gracefully, and with deep insight, about complex scientific endeavors that could ease human suffering but are fraught with myriad ethical perils.” —Publishers Weekly
