Relativity Reexamined examines relativity from a new angle and with an unconventional perspective. Topics covered range from quantum theory and relativity to gravitation and relativity quantized atomic clocks, as well as special relativity Doppler effect and spherical symmetry. A distinction is also made between mathematical coordinates and physical frames of reference. This book is comprised of eight chapters and begins by considering the development of scientific theories in general, citing examples to show how scientists' viewpoints have progressively changed. Some of the problems that have emerged, and which even Albert Einstein was unable to foresee, are highlighted. The first chapter reviews the historical sequence of events that led to quantum theory and relativity, while the second chapter focuses on some problems about restricted relativity, paying particular attention to the meaning of potential energy and the importance of field theory in relativistic theories. The following chapters analyze a variety of experimental evidences that challenge many basic assumptions in theoretical physics, focusing on the fundamental importance of the Mössbauer effect and of atomic clocks; the link between gravitation and relativity; classical problems of theoretical mechanics; and special relativity Doppler effect. A gravistatic problem with spherical symmetry is also described. This monograph will be of interest to physicists and students of physics.

Time is considered as an independent entity which cannot be reduced to the concept of matter, space or field. The point of discussion is the ?time flow? conception of N A Kozyrev (1908-1983), an outstanding Russian astronomer and natural scientist. In addition to a review of the experimental studies of ?the active properties of time?, by both Kozyrev and modern scientists, the reader will find different interpretations of Kozyrev's views and some developments of his ideas in the fields of geophysics, astrophysics, general relativity and theoretical mechanics.

The frontiers of beam research point to increasingly high energy, greater brightness and lower emittance beams with ever-increasing particle species. These demands in turn have triggered a rapidly growing number of beam phenomena that involve quantum effects. Concurrently, the violent accelerations which are becoming available through novel accelerator research may, perhaps, help to investigate fundamental physics associated with general relativity. In view of these exciting developments and the important role they may play in the next century, the world's first conference on the 'Quantum Aspects of Beam Physics', held at Monterey, California, in January 1998, attracted a broad spectrum of experts from beam physics, particle physics, laser science, astrophysics, condensed matter physics, nuclear and atomic physics. At the end of the meeting, a new term 'quantum beam physics' was coined.This book collects together the excellent reviews and papers on new advances in the field which were presented during the workshop. It should be a valuable reference to all physicists interested in the frontiers of quantum beam physics.

The present article discuses the problems of new Unitary Quantum Theory in its applications to the different aspects of the reality. There are spectacular examples of such applications. The Modern science cannot explain origin of life's.

How are words organized in the bilingual mind? How are they linked to concepts? How do bi- and multilinguals process words in their multiple languages? The first aim of this volume is to offer up-to-date answers to these questions. Its second aim is to provide readers with detailed step-by-step introductions to a variety of methodological approaches used to investigate the bilingual lexicon, from traditional neurocognitive and psycholinguistic approaches to the more recent ones that examine language use in context.
