Printed Physics

Printed Physics



The humanities, natural and technical sciences seemingly have little to say to each other despite all the trans-disciplinary efforts. The Applied Virtuality series will comprise four volumes that create and examine a discourse on the correlations between the larger contexts of ther present. Printed Physics, the first volume, begins with the discussion of developments in information technology that make the physical behavior of matter technologically programmable, allow for its factual construction, industrial production and its determination with symbols. Is it possible that a revitalization of the field of physics looms in the future similar to that which took place with geometry in the 19th century?

Language, Torah and Hermeneutics in Abraham Abulafia

Language, Torah and Hermeneutics in Abraham Abulafia



Abraham Abulafia, the founder of the ecstatic Kabbalah, exposed a mysticism that includes a deep interest in language as a universe in itself, to be studied as the philosophers study nature, in order to attain higher knowledge than natural science and speculative philosophy. The status of Hebrew as the natural, intellectual, and primordial language is discussed against the background of the medieval speculations regarding this topic.

North-East India

North-East India



North-East India, comprising the seven contiguous states around Assam, the principal state of the region, is a relatively unknown, yet very fascinating region. The forest clad peripheral mountains, home to indigenous peoples like the Nagas, Mizos and the Khasis, the densely populated Brahmaputra valley with its lush green tea gardens and the golden rice fields, the moderately populated hill regions and plateaus, and the sparsely inhabited Himalayas, form a unique mosaic of natural and cultural landscapes and human interactions, with unparalleled diversity.

Systemic Functional Grammar in Natural Language Generation

Systemic Functional Grammar in Natural Language Generation



This volume deals with the computational application of systemic functional grammar (SFG) for natural language generation. In particular, it describes the implementation of a fragment of the grammar of German in the computational framework of KOMET-PENMAN for multilingual generation. The text also presents a specification of explicit well-formedness constraints on syntagmatic structure which are defined in the form of typed feature structures. It thus achieves a model of systemic functional grammar that unites both the strengths of systemics, such as stratification, functional diversification.

Natural Fabrications

Natural Fabrications



The spectacular success of the scientific enterprise over the last four hundred years has led to the promise of an all encompassing vision of the natural world. In this elegant picture, everything we observe is based upon just a few fundamental processes and entities. The almost infinite variety and complexity of the world is thus the product of emergence. But the concept of emergence is fraught with controversy and confusion. This book ponders the question of how emergence should be understood within the scientific picture, and whether a complete vision of the world can be attained that includes consciousness.




Dating Torrential Processes on Fans and Cones

Dating Torrential Processes on Fans and Cones



This book provides a detailed overview on methods used for the dating of past torrential activity on fans and cones and fosters the discussion on the impact of past and potential future climate change on torrential processes. The book has a clear focus on the practical applications of these methods, complemented by case studies. The limits of each dating method in case of excessive natural and human interventions on fans and cones are shown.




Transport and Reactivity of Solutions in Confined Hydrosystems

Transport and Reactivity of Solutions in Confined Hydrosystems



The present work reflects a multi-disciplinary effort to address the topic of confined hydrosystems developed with a cross-fertilization panel of physics, chemists, biologists, soil and earth scientists. Confined hydrosystems include all situations in natural settings wherein the extent of the liquid phase is limited so that the solid-liquid and/or liquid-air interfaces may be critical to the properties of the whole system. Primarily, this so-called residual solution is occluded in pores/channels in such a way that decreases its tendency to evaporation, and makes it long-lasting in arid (Earth deserts) and hyper-arid (Mars soils) areas. The associated physics is available from domains like capillarity, adsorption and wetting, and surface forces. However, many processes are still to understand due to the close relationship between local structure and matter properties, the subtle interplay between the host and the guest, the complex intermingling among static reactivity and migration pathway.

Nonequilibrium Thermodynamics

Nonequilibrium Thermodynamics



Natural phenomena consist of simultaneously occurring transport processes and chemical reactions. These processes may interact with each other and may lead to self-organized structures, fluctuations, instabilities, and evolutionary systems. Nonequilibrium Thermodynamics, 3rd edition emphasizes the unifying role of thermodynamics in analyzing the natural phenomena.

The W3 Algebra

The W3 Algebra



‘W’ algebras are nonlinear generalizations of Lie algebras that arise in the context of two-dimensional conformal field theories when one explores higher-spin extensions of the Virasoro algebra. They provide the underlying symmetry algebra of certain string generalizations which allow the extended world sheet gravity. This book presents such gravity theories, concentrating on the algebra of physical operators determined from an analysis of the corresponding BRST cohomology. It develops the representation theory of ‘W’ algebras needed to extend the standard techniques which were so successful in treating linear algebras. For certain strings corresponding to ‘W’N gravity we show that the operator cohomology has a natural geometric model. This result suggests new directions for the study of ‘W’ geometry.

The Theory of Descriptions

The Theory of Descriptions



This book combines a historical and philosophical study of Russell’s theory of descriptions. It defends, develops, and extends the theory as a contribution to natural language semantics while also arguing for a reassessment of the importance of linguistic inquiry to Russell’s philosophical project.
