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.

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.     

邮票上的物理学史（51）——希特勒统治下的德国物理学家

本节我们暂不讨论物理学本身的发展 ,而看看外部社会环境如何影响科学的存在和发展进程 :一个法西斯独裁政权如何断送了德国的物理学在世界上的领先地位 ,以及不同的德国物理学家在这个特殊的环境下的不同表现 .1 91 8年 ,德国在第一次世界大战中战败 ,德皇退位 ,成立了魏玛共和国 .割地赔款 ,经济崩溃 ,马克思急剧贬值 ,通货膨胀达到天文数字 (图 1是德国 1 92 3年发行的一张普通邮票 ,面值为 2亿马克 ),人民生活困苦 ,社会上充斥不满情绪 ,民族主义恶性膨胀 .希特勒于 1 92 0年组织国家社会主义…     

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.     

Dark matter, neutron stars, and strange quark matter

We show that self-annihilating weakly interacting massive particle (WIMP) dark matter accreted onto neutron stars may provide a mechanism to seed compact objects with long-lived lumps of strange quark matter, or strangelets, for WIMP masses above a few GeV. This effect may trigger a conversion of most of the star into a strange star. We use an energy estimate for the long-lived strangelet based on the Fermi-gas model combined with the MIT bag model to set a new limit on the possible values of the WIMP mass that can be especially relevant for subdominant species of massive neutralinos.     

物理工作者与产业

文章从产业发展的角度阐述了物理学与技术的源与流的关系，指出经典物理和理论物理仍然是几乎所有技术和产业的基础．在许多工程领域中，物理工作者都有机会成为优秀的企业家或销售经理，但他们通常不能如愿以偿，一个简单的原因在于他们缺乏与人交往的技巧．一个人要想在产业界有所建树，必须具备四个要素，即能力(competence)，交流(communication)，合作(cooperation)和责任心(commitment)，也就是4C．文章描述了作者本人从一名物理系的研究生成长为美国非常有名的红外仪器公司的CEO(首席执行官)的经历．作为物理工作者出身的企业家，作者最深的感受在于，知识是重要的，但并不充分．必须牢记产业的最终目的是盈利．在产业界，利润和竞争是每天都存在的严酷的事实，上述的四个要素(4C)则是成功的法宝．
