Weaving together lyrical history and personal memoir, Virdi powerfully examines society’s—and her own—perception of life as a deaf person in America.

At the age of four, Jaipreet Virdi’s world went silent. A severe case of meningitis left her alive but deaf, suddenly treated differently by everyone. Her deafness downplayed by society and doctors, she struggled to “pass” as hearing for most of her life. Countless cures, treatments, and technologies led to dead ends. Never quite deaf enough for the Deaf community or quite hearing enough for the “normal” majority, Virdi was stuck in aural limbo for years. It wasn’t until her thirties, exasperated by problems with new digital hearing aids, that she began to actively assert her deafness and reexamine society’s—and her own—perception of life as a deaf person in America.
 
Through lyrical history and personal memoir, Hearing Happiness raises pivotal questions about deafness in American society and the endless quest for a cure. Taking us from the 1860s up to the present, Virdi combs archives and museums in order to understand the long history of curious cures: ear trumpets, violet ray apparatuses, vibrating massagers, electrotherapy machines, airplane diving, bloodletting, skull hammering, and many more. Hundreds of procedures and products have promised grand miracles but always failed to deliver a universal cure—a harmful legacy that is still present in contemporary biomedicine.

Weaving Virdi’s own experiences together with her exploration into the fascinating history of deafness cures, Hearing Happiness is a powerful story that America needs to hear.

In 1918, the U.S. Army Signal Corps sent 223 women to France at General Pershing’s explicit request. They were masters of the latest technology: the telephone switchboard. While suffragettes picketed the White House and President Wilson struggled to persuade a segregationist Congress to give women of all races the vote, these courageous young women swore the army oath and settled into their new roles. Elizabeth Cobbs reveals the challenges they faced in a war zone where male soldiers wooed, mocked, and ultimately celebrated them.

The army discharged the last Hello Girls in 1920, the year Congress ratified the Nineteenth Amendment. When they sailed home, they were unexpectedly dismissed without veterans’ benefits and began a sixty-year battle that a handful of survivors carried to triumph in 1979.

“What an eye-opener! Cobbs unearths the original letters and diaries of these forgotten heroines and weaves them into a fascinating narrative with energy and zest.”
—Cokie Roberts, author of Capital Dames

“This engaging history crackles with admiration for the women who served in the U.S. Army Signal Corps during the First World War, becoming the country’s first female soldiers.”
—New Yorker

“Utterly delightful… Cobbs very adroitly weaves the story of the Signal Corps into that larger story of American women fighting for the right to vote, but it’s the warm, fascinating job she does bringing her cast…to life that gives this book its memorable charisma… This terrific book pays them a long-warranted tribute.”
—Christian Science Monitor

“Cobbs is particularly good at spotlighting how closely the service of military women like the Hello Girls was tied to the success of the suffrage movement.”

The first international history of railroads and railroad infrastructure told through stunningly reproduced maps.

Since their origins in eighteenth-century England, railroads have spread across the globe, changing everything in their path, from where and how people grew and made things to where and how they lived and moved. Railroads rewrote not only world geography but also the history of maps and mapping. Today, the needs of train companies and their users continue to shape the maps we consume and consult.

Featuring full-color maps primarily from the British Library's distinguished collection—many of them never before published—A History of the Railroad in 100 Maps is the first international history of railroads and railroad infrastructure told through maps. Jeremy Black includes examples from six continents, spanning a variety of uses from railroad planning and operations to guides for passengers, shippers, and tourists.

Arranged chronologically, the maps are accompanied by explanatory text that sheds light on the political, military, and urban development histories associated with the spread of railroads. A final chapter considers railroad maps from games, books, and other cultural artifacts. For anyone interested in the history of railroads or maps, A History of the Railroad in 100 Maps will offer new and unexpected insights into their intertwined global history.

“How do we think?” N. Katherine Hayles poses this question at the beginning of this bracing exploration of the idea that we think through, with, and alongside media. As the age of print passes and new technologies appear every day, this proposition has become far more complicated, particularly for the traditionally print-based disciplines in the humanities and qualitative social sciences. With a rift growing between digital scholarship and its print-based counterpart, Hayles argues for contemporary technogenesis—the belief that humans and technics are coevolving—and advocates for what she calls comparative media studies, a new approach to locating digital work within print traditions and vice versa.

The Hubble Space Telescope is the largest, most complex, and most powerful observatory ever deployed in space, designed to allow astronomers to look far back into our own cosmic past with unprecedented clarity. Yet from its launch in 1990, when it was discovered that a flawed mirror was causing severe “myopia” and sending fuzzy images back to Earth, the HST has been at the center of a controversy over who was at fault for the flaw and how it should be fixed. Now Eric Chaisson, a former senior scientist on the HST project, tells the inside story of the much heralded mission to fix the telescope. Drawing on his journals, Chaisson recreates the day-to-day struggles of scientists, politicians, and publicists to fix the telescope and control the political spin. Illustrated with “before and after” full-color pictures from the telescope and updated with a new preface, The Hubble Wars tells an engaging tale of scientific comedy and error.

In this new edition, coming at the half-way point in the HST’s planned mission of fifteen years, Chaisson has brought the Hubble story up-to-date by sorting out the spectacular from the mundane contributions the HST has made to our knowledge of the Solar System, the Milky Way Galaxy, and the distant galaxies of deep space.

The prefix “hyper” refers to multiplicity and abundance. More than a physical space, a hypercity is a real city overlaid with information networks that document the past, catalyze the present, and project future possibilities. Hypercities are always under construction.

Todd Presner, David Shepard, and Yoh Kawano put digital humanities theory into practice to chart the proliferating cultural records of places around the world. A digital platform transmogrified into a book, it explains the ambitious online project of the same name that maps the historical layers of city spaces in an interactive, hypermedia environment. The authors examine the media archaeology of Google Earth and the cultural–historical meaning of map projections, and explore recent events—the “Arab Spring” and the Fukushima nuclear power plant disaster—through social media mapping that incorporates data visualizations, photographic documents, and Twitter streams. A collaboratively authored and designed work, HyperCities includes a “ghost map” of downtown Los Angeles, polyvocal memory maps of LA’s historic Filipinotown, avatar-based explorations of ancient Rome, and hour-by-hour mappings of the Tehran election protests of 2009.

Not a book about maps in the literal sense, HyperCities describes thick mapping: the humanist project of participating and listening that transforms mapping into an ethical undertaking. Ultimately, the digital humanities do not consist merely of computer-based methods for analyzing information. They are a means of integrating scholarship with the world of lived experience, making sense of the past in the layered spaces of the present for the sake of the open future.
