Space and time are probably the most important elements in physics. Within the memory of man, all essential things are represented within the frame of space-time pictures. This is obviously the most basic information. What can we say about space and time? It is normally assumed that the space is a container filled with matter and that the time is just that which we measure with our clocks. However, there are some reasons to take another standpoint and to consider this container-conception as unrealistic, as prejudice so to say. Already the philosopher Immanuel Kant pointed on this serious problem.In this monograph, the author discusses the so-called projection theory. In contrast to the container-conception (reality is embedded in space and time), within projection theory the physical reality is projected onto space and time and quantum processes are of particular relevance. Like Whitehead and Bergson, the author argues for the primacy of process.One of the most interesting results is that projection theory automatically leads to a new aspect for the notion “time”. Here we have not only the time of conventional physics, which is exclusively treated as an external parameter, but we obtain within projection theory a system-specific time. Just this system-specific time might be of fundamental importance in the future description of physical systems. For example, the self-assembly of nano-systems could lead to predictions that are even not thinkable within usual physics. Also in connection with cosmology the projection principle must inevitably lead to fundamentally new statements.

The 4th Experimental Chaos Conference was a forum for members of the scientific and engineering communities to discuss recent developments in, and techniques of, experimental nonlinear dynamics. The focus of this important conference was on actual realizations of nonlinear and chaotic systems. The latest developments in applications of nonlinear dynamics and chaos were presented, the requirement being that all presentations were actually implemented in experiments or devices. The areas covered were spatio-temporal patterns, optical chaos, biological dynamics, communication and synchronization, control of chaotic systems, mechanical dynamics, fluid dynamics, quantum chaos, and chaotic condensed matter systems.

This volume consists of a selection of scholarly essays from literature, philosophy and history on the conception of reality as understood by Rabindranath Tagore and Albert Einstein. The nature of reality has been a long-debated issue among scientists and philosophers. Tagore (1861–1941) met Einstein (1879–1955) at the latter’s house in Kaputh, Germany on 14 July 1930 and had a long conversation on this issue. This conversation has been widely quoted and discussed by scientists, philosophers and scholars from the literary world. The important question that Tagore and Einstein discussed was whether the world is a unity dependent on humanity, or the world is a reality independent of the human factor. Einstein believed that reality is independent of the mind and the human factor. On the other hand, Tagore adopted the opposite view. Nevertheless, both Einstein and Tagore claimed to be realists — their conceptions of reality were obviously fundamentally different. Where does the difference lie? Can it be harmonized at a deeper level? This volume brings together for the first time a gamut of views on this subject from eminent scholars. It presents some key reflections on reality, language, poetry, truth, science, personality, human sciences, virtue ethics, intelligibility and creativity. It will be useful to scholars and researchers of philosophy, literature, history and political studies, as also to those interested in Tagore.

The structure of quantum theory permits interference of indistinguishable paths. At the same time, however, it also limits such interference to certain orders and any higher-order interference is prohibited. This thesis develops and studies concepts to test quantum theory with higher-order interference using many-particle correlations, the latter being generally richer and typically more subtle than single-particle correlations. It is demonstrated that quantum theory in general allows for interference up to order 2M in M-particle correlations. Depending on the mutual coherence of the particles, however, the related interference hierarchy can terminate earlier. In this thesis, we show that mutually coherent particles can exhibit interference of the highest orders allowed. We further demonstrate that interference of mutually incoherent particles truncates already at order M+1, although interference of the latter is principally more multifaceted than their coherent counterpart. We introduce two families of many-particle Sorkin parameters, whose members are expected to be all zero when quantum mechanics holds. As proof of concept, we demonstrate the disparate vanishing of such higher-order interference terms as a function of coherence in experiments with mutually coherent and incoherent sources. Finally, we investigate the influence of exotic kinked or looped quantum paths, which are permitted by Feynman’s path integral approach, in such setups.

In contrast to other publications this work discusses Nanoscience strictly at the ultimate level where the properties of atomic matter emerge. The renowned author presents an interdisciplinary approach leading to the forefront of research of quantum-theoretical aspects of time, selforganizing nanoprocesses, brain functions, the matter-mind problem, behaviour research and philosophical questions.

This book offers a history of the instrumentation used to materialize the early thought experiments devised in the Einstein-Bohr disputes over the foundations of quantum mechanics. It shows how the second world war and cold war fostered the development of materials, instruments, and systems that made it possible to create, manipulate, and detect single quantum systems, thus creating the material conditions for experiments in foundations of quantum mechanics and for a broad spectrum of experimental inquiries on the structure and properties of matter which underlay the creation of new research fields such as quantum optics, quantum information, and atomic, molecular, and optical physics. Discussing research and development performed in diverse contexts, this book reveals how physicists carried instruments, and the knowledge they embodied, through disciplinary and geographic frontiers to probe entanglement, a most intriguing feature of the quantum world.

Quantum mechanics is one of mankind's most remarkable intellectual achievements. Stunningly successful and elegant, it challenges our deepest intuitions about the world. In this book, seventeen physicists and philosophers, all deeply concerned with understanding quantum mechanics, reply to Schlosshauer's penetrating questions about the central issues. They grant us an intimate look at their radically different ways of making sense of the theory's strangeness. What is quantum mechanics about? What is it telling us about nature? Can quantum information or new experiments help lift the fog? And where are we headed next? Everyone interested in the contemporary but often longstanding conundrums of quantum theory, whether lay reader or expert, will find much food for thought in these pages. A wealth of personal reflections and anecdotes guarantee an engaging read. Participants: Guido Bacciagaluppi, Caslav Brukner, Jeffrey Bub, Arthur Fine, Christopher Fuchs, GianCarlo Ghirardi, Shelly Goldstein, Daniel Greenberger, Lucien Hardy, Anthony Leggett, Tim Maudlin, David Mermin, Lee Smolin, Antony Valentini, David Wallace, Anton Zeilinger, and Wojciech Zurek.
