    Solar and Space Physics: A Science for a Technological Society The 2013-2022 Decadal Survey in Solar and Space Physics Space Studies Board ∙ Division on Engineering & Physical Sciences ∙ August 2012 From the interior of the Sun, to the upper atmosphere and near-space environment of Earth, and outwards to a region far beyond Pluto where the Sun’s influence wanes, advances during the past decade in space physics and solar physics have yielded spectacular insights into the phenomena that affect our home in space. This report, the final product of a study requested by NASA and the National Science Foundation, presents a prioritized program of basic and applied research for 2013-2022 that will advance scientific understanding of the Sun, Sun- Earth connections and the origins of “space weather,” and the Sun’s interactions with other bodies in the solar system. The report includes recommendations directed for action by the study sponsors and by other federal agencies—especially NOAA, which is responsible for the day-to-day (“operational”) forecast of space weather. Recent Progress: Significant Advances significant progress in understanding the origin from the Past Decade and evolution of the solar wind; striking advances The disciplines of solar and space physics have made in understanding of both explosive solar flares remarkable advances over the last decade—many and the coronal mass ejections that drive space of which have come from the implementation weather; new imaging methods that permit direct of the program recommended in 2003 Solar observations of the space weather-driven changes and Space Physics Decadal Survey.

  • Sources for the History of Space Concepts in Physics: from 1845 to 1995
    CBPF-NF-084/96 SOURCES FOR THE HISTORY OF SPACE CONCEPTS IN PHYSICS: FROM 1845 TO 1995 Francisco Caruso(∗) & Roberto Moreira Xavier Centro Brasileiro de Pesquisas F´ısicas Rua Dr. Xavier Sigaud 150, Urca, 22290–180, Rio de Janeiro, Brazil Dedicated to Prof. Juan Jos´e Giambiagi, in Memoriam. “Car l`a-haut, au ciel, le paradis n’est-il pas une immense biblioth`eque? ” — Gaston Bachelard Brief Introduction Space — as other fundamental concepts in Physics, like time, causality and matter — has been the object of reflection and discussion throughout the last twenty six centuries from many different points of view. Being one of the most fundamental concepts over which scientific knowledge has been constructed, the interest on the evolution of the ideas of space in Physics would per se justify a bibliography. However, space concepts extrapolate by far the scientific domain, and permeate many other branches of human knowledge. Schematically, we could mention Philosophy, Mathematics, Aesthetics, Theology, Psychology, Literature, Architecture, Art, Music, Geography, Sociology, etc. But actually one has to keep in mind Koyr´e’s lesson: scientific knowledge of a particular epoch can not be isolated from philosophical, religious and cultural context — to understand Copernican Revolution one has to focus Protestant Reformation. Therefore, a deeper understanding of this concept can be achieved only if one attempts to consider the complex interrelations of these different branches of knowledge. A straightforward consequence of this fact is that any bibliography on the History and Philosophy of space would result incomplete and grounded on arbitrary choices: we might thus specify ours. From the begining of our collaboration on the History and Philosophy of Space in Physics — born more than ten years ago — we have decided to build up a preliminary bibliography which should include just references available at our libraries concerning a very specific problem we were mainly interested in at that time, namely, the problem of space dimensionality.

  • AS703: Introduction to Space Physics
    AS703: Introduction to Space Physics Fall 2015 Course Description The temperature of the sun's surface is 4000K-5000K, but just outside the sur- face, in a region called the corona, the temperatures exceed 1.5 million degrees K. The mechanism that heats and sus- tains these high temperatures remains unexplained. Nevertheless, these high temperatures cause the corona to expel vast quantities of material, creating the solar wind. This plasma wind travels outward from the sun interacting with all solar system bodies. When the solar wind approaches planet Earth, it com- presses and distorts the region dom- inated by the Earth's magnetic field called the magnetosphere. The magnetosphere channels the solar wind around most of the at- mosphere and also into the polar regions. This channeling process drives large currents through the magnetosphere and into the charged part of the atmosphere below it; the partially ionized region called the ionosphere. These processes frequently energize particles creating the ring current, the radiation belts, and send energized particles crashing into the neutral atmosphere creating the Au- rora Borealis. The field of space physics studies physical phenomena from the Sun's outer layers to the upper atmospheres of the planets and, ultimately, to the point where the Solar wind's influence wanes. Understanding this region enables us to have a space program and to communicate through space. It also gives insight into plasma processes throughout the universe. The goal of this course is to provide an introduction to space and solar physics. Since the local space environment is predominantly filled by plasma and electromagnetic energy, a substantial amount of time will be dedicated to learning the basics of plasma physics.

Ideologeme bringen die Überzeugung der KPCh zum Ausdruck, dass Entwicklung und Fortschritt unter ihrer Lenkung plan- und durchführbar sind, Entwicklungsziele somit erreichbar werden und zukünftiger Fortschritt generiert werden kann. Ideologeme werden als Legitimationsinstrumente eingesetzt, die sowohl eine konkrete Handlung oder Aufforderung beinhalten, wie Ziele erreicht werden können, als auch auf der Überzeugung basieren, dass der Entwicklungsweg der VR China sowie der angestrebte Fortschritt richtig sind. Sie wirken sinn- stiftend in den jeweiligen Kontext hinein und ermöglichen, dass auch über die Äußerungen der Partei hinaus deren ideologische Inhalte Kontinuität behalten. Herausforderungen wie die Realisierung planungsintensiver Großprojekte mit weitreichenden wirtschaftlichen, ökologischen und sozialen Auswirkungen, z.B. der Bau von Atomkraftwerken oder des Drei-Schluchten-Staudamms, und das Erfordernis einer Auseinandersetzung mit der Nuklearkatastrophe von Fukushima und Naturkatastrophen, wie dem Erdbeben von Wenchuan, bieten Anlass für ein Hinterfragen des von der KPCh propagierten Fortschrittsdenkens. In der vorliegenden Arbeit werden Fortschritts- und Entwicklungsideologeme in der KPCh seit dem Jahr 1949 sowie ihr Aufscheinen in den Fallbeispielen, Diskussion der Atomenergie in der VR China, des Wenchuan-Erdbebens und FAU Studien aus der Philosophischen Fakultät 12 des Drei-Schluchten-Staudamm-Projektes, untersucht.

  • The First “Non-Government” Visiting Scholars Delegate in United States
    English translation of Chinese article published in Science & Culture Review (Beijing), Vol. 7, No. 2 (2010) pp. 84-94 ______________________________________________________________________________________________ The First “Non-Government” Visiting-Scholar Delegation in the United States of America from People’s Republic of China, 1979-1981 Lui Lam Department of Physics, San Jose State University, San Jose, CA 95192-0106, USA In February, 1979, a delegation of eight scientists from the Institute of Physics, Chinese Academy of Sciences, arrived in Evanston, and became the first group of “non-government” visiting scholars ever set foot in the USA since 1949. This group consists of Qian Yongjia (钱永嘉), LI Tiecheng (李铁成), ZHENG Jiaqi (郑家祺), SHEN Juelian (沈觉涟), WANG Dingsheng (王鼎盛), CHENG Bingying (程丙英), GU Shijie (顾世杰) and LIN Lei (林磊, Lui LAM). Lin stayed for three months while the rest of the group stayed for two years. The work by Lin at Northwestern University was later published in Physical Review Letters, the most prestige physics journal in the world, and became the first paper ever published in this journal by an author from China. Here, the background of the domestic situation in China and the international relationship between China and USA leading to the visit are summarized. The formation of this delegation of visiting scholars is described, followed by the 1979 visit itself. Lastly, the influence of the visit on the careers of the delegates afterwards and on the Chinese reform-opening up movement in general is given. Key words: Institute of Physics, Reform-Opening Up Movement, visiting scholars in USA, Baodiao Movement, Haigui, Physical Review Letters I.
