Book Description
Quantum mechanics entails effects like superpositions and entanglement, which have no classical counterparts. From a technological standpoint these counterintuitive quantum aspects can be viewed as an unexploited resource that can be harnessed to support various tasks, e.g. in the domains of computation, communication, and metrology. In many applications, however, the potential of nonclassical states cannot practically be exploited due to detection inefficiencies. The authors address this limitation by experimentally realizing a novel detection scheme in which entangling interactions are time reversed. In this way, nonclassical many-particle states are disentangled, allowing them to be detected in a robust and technically feasible manner. In the context of quantum metrology, these nonlinear readout techniques extend the class of entangled probe states that can be leveraged for sensing applications without being limited by finite detector resolution. The authors present an active atom interferometer, where both the entangled state preparation and disentangling readout involve parametric amplification. This “SU(1,1)” interferometer is implemented with the help of spinor Bose–Einstein condensates, where amplification is implemented by atomic collisions leading to spin exchange.

Book Description
Franz Brentano is recognised as one of the most important philosophers of the late nineteenth and early twentieth centuries. This work, first published in English in 1988, besides being an important contribution to metaphysics in its own right, has considerable historical importance through its influence on Husserl’s views on internal time consciousness. The work is preceded by a long introduction by Stephan Körner in collaboration with Brentano’s literary executor.

Book Description
This is a collection of some works of Polish philosophers and physicists on philosophical problems of time and spacetime. Without restricting the thematic scope of the papers, the issue conceming objectivity of time flow runs as a uniting thread through most of them. Partly it is discussed directIy, and partly the authors focus on themes which are of paramount importance for one's attitude to that question. In the first six papers the authors deal with their topics against the background of contemporary physics, its theories, its difficulties and discussed conjectures. For the paper of S. Snihur that background is provided by everyday worId-outlook, and the author discusses the problem of existence and character of the future in the light of basic principles of cIassical logic. The paper of A. P61tawski, about the views of the outstanding polish philosopher Roman Ingarden, enriches the thematic scope of the coIIection introducing into it some questions from philosophical anthropology and ethics. JERZY GOLOSZ MOTION, SPACE, TIME*. Abstract. The paper discusses the properties of spacetime we study by analyzing the phenomenon of motion. Of special interest are the spacetime symmetries. the spacetime structures and the ontological status of spacetime. These problems are considered on the grounds of the c1assical theories of motion contained in Newtonian physics, special and general theory of relativity. The controversy between an absolute and a relational conception of motion and its ontological implications are also analyzed.

Book Description
"This book will be essential reading for students and researchers in the areas of postcolonial studies, French and Francophone studies, cultural studies, ethnic and racial studies, politics, literature and psychoanalysis, and all those concerned, like Fanon, with the quest for human freedom."--BOOK JACKET.

Book Description
From early examples such as Star Trek and Sapphire and Steel to more contemporary shows including Life on Mars and The Vampire Diaries, time has frequently been used as a device to allow programme makers to experiment stylistically and challenge established ways of thinking. Time on TV provides a range of exciting, accessible, yet intellectually rigorous essays that consider the many and varied ways in which telefantasy shows have explored this subject, providing the reader with a greater understanding of the importance of time to the success of genre on the small screen.
