After the Holocaust, the empty, silent spaces of bombed-out synagogues, cemeteries, and Jewish districts were all that was left in many German and Polish cities with prewar histories rich in the sights and sounds of Jewish life. What happened to this scarred landscape after the war, and how have Germans, Poles, and Jews encountered these ruins over the past sixty years? In the postwar period, city officials swept away many sites, despite protests from Jewish leaders. But in the late 1970s church groups, local residents, political dissidents, and tourists demanded the preservation of the few ruins still standing. Since the collapse of the Soviet Union in 1989, this desire to preserve and restore has grown stronger. In one of the most striking and little-studied shifts in postwar European history, the traces of a long-neglected Jewish past have gradually been recovered, thanks to the rise of heritage tourism, nostalgia for ruins, international discussions about the Holocaust, and a pervasive longing for cosmopolitanism in a globalizing world. Examining this transformation from both sides of the Iron Curtain, Michael Meng finds no divided memory along West-East lines, but rather a shared memory of tensions and paradoxes that crosses borders throughout Central Europe. His narrative reveals the changing dynamics of the local and the transnational, as Germans, Poles, Americans, and Israelis confront a built environment that is inevitably altered with the passage of time. Shattered Spaces exemplifies urban history at its best, uncovering a surprising and moving postwar story of broad contemporary interest.

Shattered Pictures of Places and Cities se adentra por las páginas autobiográficas, filosóficas y narrativas más relevantes de George Santayana discurriendo por sus viajes y geografías físicas en paralelo a sus viajes y geografías morales. Es un intento de ir más allá de la reflexión entorno a los orígenes biográficos del filósofo; de ahí que se recupere una indagación sobre su habitar el lenguaje y el arte. Santayana reconsidera los fundamentos del arte de la memoria clásica en su autobiografía, para formular una nueva propuesta estética donde el arte y la vida se funden y se confunden, estimulándose recíprocamente. Hila una filosofía del viaje y del lugar, donde se privilegia una noción del habitar que ilumina nuestra condición de nómadas -en la vida y en el pensamiento-, y nuestra trágica estable inestabilidad en este mundo.

Within cognitive science, two approaches currently dominate the problem of modeling representations. The symbolic approach views cognition as computation involving symbolic manipulation. Connectionism, a special case of associationism, models associations using artificial neuron networks. Peter Gärdenfors offers his theory of conceptual representations as a bridge between the symbolic and connectionist approaches. Symbolic representation is particularly weak at modeling concept learning, which is paramount for understanding many cognitive phenomena. Concept learning is closely tied to the notion of similarity, which is also poorly served by the symbolic approach. Gärdenfors's theory of conceptual spaces presents a framework for representing information on the conceptual level. A conceptual space is built up from geometrical structures based on a number of quality dimensions. The main applications of the theory are on the constructive side of cognitive science: as a constructive model the theory can be applied to the development of artificial systems capable of solving cognitive tasks. Gärdenfors also shows how conceptual spaces can serve as an explanatory framework for a number of empirical theories, in particular those concerning concept formation, induction, and semantics. His aim is to present a coherent research program that can be used as a basis for more detailed investigations.

It is without question that this book will elicit a lot of commentary, both good and bad, from experts and interested people as well. Herein, Einstein's various "thought experiments", that led to the concept of Space-Time Continuum, are more thoroughly examined and extended. Upon closer examination, a number of very serious flaws were uncovered in the theories of Special Relativity (SR) and General Relativity (GR). As a consequence, the combined flaws essentially lead to serious "cracks" in the overall Relativity theory and the subsequent "shattering" of the Space-Time Continuum concept. This book does not present complicated and boring physics or mathematics. Instead, it approaches the subject the same way that Einstein did before he developed his mathematics; --through visual "thought experiments". So, sit back and enjoy a return to reality.

In Vanishing Vienna historian Frances Tanzer traces the reconstruction of Viennese culture from the 1938 German annexation through the early 1960s. The book reveals continuity in Vienna’s cultural history across this period and a framework for interpreting Viennese culture that relies on antisemitism, philosemitism, and a related discourse of Jewish presence and absence. This observation demands a new chronology of cultural reconstruction that links the Nazi and postwar years, and a new geography that includes the history of refugees from Nazi Vienna. Rather than presenting the Nazi, exile, and postwar periods as discrete chapters of Vienna’s history, Tanzer argues that they are part of a continuous spectrum of cultural evolution—the result of which was the creation of a coherent Austrian identity and culture that emerged by the 1950s. As she shows, antisemitism and philosemitism were not contradictory forces in post-Nazi Austrian culture. They were deeply interconnected aspirations in a city where nostalgia for the past dominated cultural reconstruction efforts and supported seemingly contradictory impulses. Viennese nostalgia at times concealed the perpetuation of antisemitic fantasies of the city without Jews. At the same time, the postwar desire to return to a pre-Nazi past relied upon notions of Austrian culture that Austrian Jews perfected in exile, as well as on the symbolic remigration of a mostly imagined “Jewish” culture now taxed with redeeming Austria in the aftermath of the Holocaust. From this perspective, philosemitism is much more than a simple inversion of antisemitism—instead, Tanzer argues, philosemitism, problematic as it may be, defines Vienna in the era of postwar reconstruction. In this way, Vanishing Vienna uncovers a rarely discussed phenomenon of the aftermath of the Holocaust—a society that consumes, redefines, and bestows symbolic meaning on the victims in their absence.

In the fully rewritten third edition of this classic text, Nicholas Mirzoeff introduces visual culture as visual activism, or activating the visible. In this view, visual culture is a practice: a way of doing, making, and seeing. The 12 new chapters begin with five foundational concepts, including Indigenous ways of seeing, visual activism in the wake of slavery, and unfixing the gaze. The second section outlines three currently successful tactics of visual activism: removal of statues and monuments; restitution of cultural property; and practices of repair and reparations. The final section addresses catastrophe and trauma, from Palestine’s Nakba to the climate disaster and the intersections of plague and war. Each section also includes new, in-depth case studies called "Visualizations," ranging from oil painting to Kongo power figures and the mediated practice of taking a knee. Engaging with questions of racializing, colonialism, and undoing gender throughout, this edition maps the activist turn in the field since 2014 and sets directions for its future expansion. This is a key text in visual culture studies and an essential resource for research and teaching in the field.

Shattered Dreams delves into the personal stories and recollections of several men and women who were in line to fly a specific or future space mission but lost that opportunity due to personal reasons, mission cancellations, or even tragedies. While some of the subjects are familiar names in spaceflight history, the accounts of others are told here for the first time. Colin Burgess features spaceflight candidates from the United States, Russia, Indonesia, Australia, and Great Britain. Shattered Dreams brings to new life such episodes and upheavals in spaceflight history as the saga of the three Apollo missions that were cancelled due to budgetary constraints and never flew; NASA astronaut Patricia Hilliard Robertson, who died of burn injuries after her airplane crashed before she had a chance to fly into space; and a female cosmonaut who might have become the first journalist to fly in space. Another NASA astronaut was preparing to fly an Apollo mission before he was diagnosed with a disqualifying illness. There is also the amazing story of the pilot who could have bailed out of his damaged aircraft but held off while heroically avoiding a populated area and later applied to NASA to fulfill his cherished dream of becoming an astronaut despite having lost both legs in the accident. These are the incredibly human stories of competitive realists fired with an unquenchable passion. Their accounts reveal in their own words—and those of others close to them—how their shared ambition would go awry through personal accidents, illness, the Challenger disaster, death, or other circumstances.
