Download or read book The Multinational History of Strasbourg Astronomical Observatory written by Andre HECK and published by Springer Science & Business Media. This book was released on 2006-04-04 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Strasbourg Astronomical Observatory is quite an interesting place for historians: several changes of nationality between France and Germany, high-profile scientists having been based there, big projects born or installed within its walls, and so on. Most of the documents circulating on the history of the Observatory and on related matters have however been so far poorly referenced, if at all. This made necessary the compilation of a volume such as this one, offering fully-documented historical facts and references on the first decades of the Observatory history, authored by both French and German specialists. The experts contributing to this book have done their best to write in a way understandable to readers not necessarily hyperspecialized in astronomy nor in the details of European history. Several appendices conclude the book: lists of council members and of Observatory scientific personnel, as well as a compendium of the institutional publications until the year 2000.

This book was released on 1956-01-02 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: 191 Apart from numerous difficulties arising from the high pressure technique as such, there is a natural limitation to the possibility of applying a hydrostatic pressure, since liquids under pressure will solidify above a certain pressure limit. 8 2 Up to pressures of 3 X 10 kg.jm. at room temperature, a liquid like isopentane can be used. For higher pressures helium gas may be used, perhaps to about 9 2 10 kg.jm. , but BRIDGMAN already encountered enormous leakage difficulties 7 when using this gas at 7.10 kg.jm.2 at 90° K. A solution has been found by applying mechanical pressure for the range 8 9 2 between 3 X 10 and 10 kg.jm. , by using silver chloride as transmittant. In this case, however, one has to apply unknown corrections for shearing stress and deformation of the sample, a problem which BRIDGMAN solved experimentally by a determination of the resistivity in the pressure region between 2 and 8 2 5 X 10 kg.jm. , by the hydrostatic and by the mechanical pressure method as well, and applying the correction factor thus determined to the results obtained at higher pressures. Though this method seems to be right in good approximation, the data for the highest pressures are to be considered as less accurate.

Available in PDF, EPUB and Kindle. Book excerpt: 159 elements only between states which differ in one of the single-electron wave functions, in short, HeR induces only one-electron transitions. The matrix elements 1mn and Pmn reduce to matrix elements between the single-electron wave functions. We are interested primarily in crystalline solids for which the band model is a good approximation. The Bloch single-electron wave function in this model has the form: N'I ili-';; U. r.;;) ( (1.14) ""nk r, =e nh\r , where n is the band index and U (r) has the periodicity of the lattice. The form of the Bloch function follows from the translational symmetry of the crystal, and the matrix elements between Bloch states are subject to the condition of wave-vector conservation: k'=k, for

Download or read book Advances in Cryogenic Engineering written by K. D. Timmerhaus and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 657 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 1960 Cryogenic Engineering Conference Committee is pleased to present the papers of the 1960 Cryogenic Engineering Conference. Discussion of the papers, wherever available, has also been included to make the papers more valuable and interesting to the reader. This annual meeting once again has been held in Boulder, Colorado. Many delegates will recall that similar meetings were held in Boulder in 1954, 1956 and 1957. However, this year, because of the continued growth of this conference, the National Bureau of Standards Boulder Laboratories was joined by the College of Engineering of the University of Colorado in hosting this sixth national con ference. The Cryogenic Engineering Conference Committee is happy to acknowledge the help of an Editorial Committee which contributed valuable assistance in the difficult and thankless task of screening the preliminary papers and also re viewing the final drafts. This committee headedby R. B. jacobs, who also served as chairman for the Conference Committee, consisted of R. W. Arnett, D. B. Chelton, R. J. Corruccini, T. M. Flynn, R. H. Kropschot, R. M. McClintock, A. F. Schmidt, L. E. Scott and W. A. Wilson.

Download or read book The Mie Theory written by Wolfram Hergert and published by Springer. This book was released on 2012-06-30 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents in a concise way the Mie theory and its current applications. It begins with an overview of current theories, computational methods, experimental techniques, and applications of optics of small particles. There is also some biographic information on Gustav Mie, who published his famous paper on the colour of Gold colloids in 1908. The Mie solution for the light scattering of small spherical particles set the basis for more advanced scattering theories and today there are many methods to calculate light scattering and absorption for practically any shape and composition of particles. The optics of small particles is of interest in industrial, atmospheric, astronomic and other research. The book covers the latest developments in divers fields in scattering theory such as plasmon resonance, multiple scattering and optical force.

Download or read book The Expanding Earth written by Pascual Jordan and published by Elsevier. This book was released on 2016-05-24 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: International Series of Monographs in Natural Philosophy, Volume 37: The Expanding Earth: Some Consequences of Dirac's Gravitation Hypothesis focuses on the applications of Dirac's gravitation hypothesis. The book first discusses objections to Dirac's hypothesis and expansion cracks, including geological chronology, astrophysical objections, rift valleys, rills of the moon, deep-sea trenches, and oceanic rifts. The text then looks at the origin of the oceans, as well as growth and shrink of continents, expansion and formation of oceans, growth of land areas, and paleomagnetism. The manuscript examines the physics of the earth-moon system. Topics include rheology and seismic exploration of the earth's interior; quantitative data about the earth's expansion; and Dirac's hypothesis and the many-body problem. The book also offers information on volcanoes, lunar craters, folded mountains, and ice ages. Topics include Binge's explanation of volcanism, folded mountains, and submarine tablemounts and currents. The text is a dependable source of data for readers interested in Dirac's gravitation hypothesis.
