Mind,matter, and quantum mechanics

A theory of psychophysical phenomena is proposed. It resolves simultaneously four basic problems of science, namely the problems of the connections between:(1) mind and matter,(2) quantum theory and reality,(3) relativity theory and becoming, and (4) relativity theory and Bell's theorem.This work was supported by the Director, Office of Energy Research, Office of High Energy and Nuclear Physics, Division of High Energy Physics of the U.S. Department of Energy under Contract W-7405-EN-G-48.

两位物理学家的传说

很难想象,在物理学领域有比惠勒(John Archibald Wheeler)和费曼(Richard Feynman)这两位还要花样百出的心智组合。费曼于1939 年来到普林斯顿大学,希望在维格纳(Eugene Wigner)的指导下完成博士学业,然而到了那儿他才发现自己已经被分配给了惠勒,而那个家伙的年纪大他不到七岁。这两位极具创造力的思想家,彼此提点,相互协作,在他们的游戏中成功登顶。在《量子迷踪：费曼和惠勒如何玩转时间与实在》(The Quantum Labyrinth：How Richard Feynman and John Wheeler Revolutionized Time and Reality)这本书里,物理学家兼科学作家保罗·哈尔彭(Paul Halpern)详细描绘这对搭档的事业和关系。     

SLE for theoretical physicists

This article provides an introduction to Schramm (stochastic)-Loewner evolution (SLE) and to its connection with conformal field theory, from the point of view of its application to two-dimensional critical behaviour. The emphasis is on the conceptual ideas rather than rigorous proofs.     

Titanic Hungarian refugee physicists

The origins, composition and mode of propagation of the small earth movements known as microseisms are described. A number of instruments for recording them and several methods for determining their direction of arrival at the recording site are described in detail. Some recent theoretical and instrumental developments are discussed.     

Two post-Alikhanian generations of physicists

Artem Alikhanian, famous Soviet physicist, was one of founders of experimental nuclear and cosmic-ray physics in USSR and in Armenia. A result of his activity is subsequent two generations of professional physicists presenting the real wealth of Armenian science.

Topological quantum mechanics for physicists

This text is an attempt to write an introduction and outline of main results of topological quantum mechanics for readers with a physical background. Instead of presenting rigorous mathematical formulations, we concentrate on explanation of the physical ideas that underline most of the constructions. We review here topological quantum mechanics, since it is the simplest in the diverse family of topological theories, which contains most of their common properties.     

Introduction to protein folding for physicists

The prediction of the three-dimensional native structure of proteins from the knowledge of their amino acid sequence, known as the protein folding problem, is one of the most important yet unsolved issues of modern science. Since the conformational behaviour of flexible molecules is nothing more than a complex physical problem, increasingly more physicists are moving into the study of protein systems, bringing with them powerful mathematical and computational tools, as well as the sharp intuition and deep images inherent to the physics discipline. This work attempts to facilitate the first steps of such a transition. In order to achieve this goal, we provide an exhaustive account of the reasons of enormous relevance underlying the protein folding problem and summarize the present-day status of the methods aimed at solving it. We also provide an introduction to the particular structure of these biological heteropolymers, and we physically define the problem stating the assumptions behind this (commonly implicit) definition. Finally, we review the ‘special flavour’ of statistical mechanics that is typically used to study the astronomically large phase spaces of macromolecules. Throughout the whole work, much material that is found scattered in the literature has been put together here to improve comprehension and to serve as a handy reference.
