The Elementary Process Theory


Book Description

On the one hand, theories of modern physics are very successful in their areas of application. But on the other hand, the irreconcilability of General Relativity (GR) and Quantum Electrodynamics (QED) suggests that these theories of modern physics are not the final answer regarding the fundamental workings of the universe. This monograph takes the position that the key to advances in the foundations of physics lies in the hypothesis that massive systems made up of antimatter are repulsed by the gravitational field of a body of ordinary matter: this hypothesis takes us to an uncharted territory where GR and QED do not hold up. From there the Elementary Process Theory (EPT) is developed: this is a collection of seven generalized process-physical principles that do hold up if the hypothesis is a fact of nature. Using four-dimensionalistic terminology, the EPT abstractly describes an elementary process in the temporal evolution of a massive system that interacts with its environment. The idea is that these elementary processes take place at Planck scale and are essentially all the same, regardless of the type of interaction that takes place: the EPT is thus intended as a candidate for a unifying scheme that applies to all four basic interactions. By mathematical modeling, the relation is explored between the EPT and classical mechanics, quantum mechanics, special relativity and GR.




The Elementary Process Of Bremsstrahlung


Book Description

This book deals with the theory and experiment of the elementary process of bremsstrahlung, where photons are detected in coincidence with decelerated outgoing electrons. Such experiments allow for a more stringent check of the theoretical work. The main emphasis is laid on electron-atom bremsstrahlung and electron-electron bremsstrahlung, but further bremsstrahlung processes are also dealt with. In the theoretical parts, triply differential cross sections are derived in various approximations, including electron spin and photon-polarization. In the experimental sections, electron-photon coincidence experiments are discussed. These are done partly with transversely polarized electron beams and partly with detectors for the bremsstrahlung linear polarization.

The Reflexive Universe


Book Description

Twentieth-century developments in quantum physics, together with an emerging science of consciousness, have created the need for a new cosmology, or model of the universe. The theory of process contained in THE REFLEXIVE UNIVERSE places consciousness within the context of contemporary science. One of the central themes of this extraordinary work is that each successive organization of matter, from fundamental particles in physics to living organisms, expresses a particular stage in the evolution of mind. Starting with the photon, the basic unit of light, and moving through atomic physics, molecular chemistry, the morphology of plants and animals and finally to levels of human evolution, Young develops his theory in vivid step-by-step detail. Consciousness, in his point of view, is not isolated from the material universe. It exists in a continuum, one in which physical and nonphysical realms can be linked and the teachings of mythology and religion can be integrated.

An Introduction to the Theory of Point Processes


Book Description

Point processes and random measures find wide applicability in telecommunications, earthquakes, image analysis, spatial point patterns, and stereology, to name but a few areas. The authors have made a major reshaping of their work in their first edition of 1988 and now present their Introduction to the Theory of Point Processes in two volumes with sub-titles Elementary Theory and Models and General Theory and Structure. Volume One contains the introductory chapters from the first edition, together with an informal treatment of some of the later material intended to make it more accessible to readers primarily interested in models and applications. The main new material in this volume relates to marked point processes and to processes evolving in time, where the conditional intensity methodology provides a basis for model building, inference, and prediction. There are abundant examples whose purpose is both didactic and to illustrate further applications of the ideas and models that are the main substance of the text.

From the reviews: "Almost thirty years after its first edition, this charming book continues to be an excellent text for teaching and for self study." -- STATISTICAL PAPERS




Statistical Thermodynamics of Nonequilibrium Processes


Book Description

The structure of the theory ofthermodynamics has changed enormously since its inception in the middle of the nineteenth century. Shortly after Thomson and Clausius enunciated their versions of the Second Law, Clausius, Maxwell, and Boltzmann began actively pursuing the molecular basis of thermo dynamics, work that culminated in the Boltzmann equation and the theory of transport processes in dilute gases. Much later, Onsager undertook the elucidation of the symmetry oftransport coefficients and, thereby, established himself as the father of the theory of nonequilibrium thermodynamics. Com bining the statistical ideas of Gibbs and Langevin with the phenomenological transport equations, Onsager and others went on to develop a consistent statistical theory of irreversible processes. The power of that theory is in its ability to relate measurable quantities, such as transport coefficients and thermodynamic derivatives, to the results of experimental measurements. As powerful as that theory is, it is linear and limited in validity to a neighborhood of equilibrium. In recent years it has been possible to extend the statistical theory of nonequilibrium processes to include nonlinear effects. The modern theory, as expounded in this book, is applicable to a wide variety of systems both close to and far from equilibrium. The theory is based on the notion of elementary molecular processes, which manifest themselves as random changes in the extensive variables characterizing a system. The theory has a hierarchical character and, thus, can be applied at various levels of molecular detail.




Elementary Processes in Excitations and Reactions on Solid Surfaces


Book Description

Elementary Processes in Excitations and Reactions on Solid Surfaces explores the fundamental nature of dynamics on solid surfaces. Attempts are made to reveal various aspects of elementary processes in excitations and reactions on solid surfaces by recent theoretical and experimental developments of the subjects such as molecular beams interacting with surfaces, ion beam scattering, laser-induced dynamical processes, electronically induced dynamical processes, and optical properties of solid surfaces. This volume is devided into three parts. Part I is concerned mainly with the rich reaction dynamics on potential-energy surfaces. Part II is devoted to the interplay of excitations. In Part III, new and rapidly developing methods are introduced.




Handbook of Learning and Cognitive Processes


Book Description

Is it possible at present to identify a core cluster of theoretical ideas, concepts, and methods with which everyone working in the area of learning and cognition needs to be familiar? Would it be possible to make explicit the relationships that we feel do or must exist among the various subspecialties, ranging from conditioning through perceptual learning and memory to psycholinguistics, and to present these in a sufficiently organized way to help specialists and non-specialists alike in relating particular lines of research to the broader spectrum of activity? These questions were posed to a substantial number of investigators who were most active in developing the ideas and doing the research in the early 1970s. Originally published between 1975 and 1978, their response constitutes this 6-volume Handbook of Learning and Cognitive Processes. The volumes survey the research and theory on learning and cognitive processes that were rapidly developing at the time. The primary orientation was to concentrate on research and models aimed toward the development of general cognitive theory. They were up-to-date with regard to theoretical and technical developments, and sufficiently self-contained to be readable by anyone with a reasonable scientific background, regardless of their acquaintance with the technical jargon of particular specialties. Previously out of print, the Handbook is now available again, as a set or as individual volumes.
