20世纪是物理学的黄金世纪.提到20世纪的物理教育大师,一般业内人士会想到汤姆孙、卢瑟福和玻尔,认为这3代师徒是最出色的物理教育家,重要的理由之一是他们培养了多名诺贝尔奖得主.事实上马克斯.玻恩创立了哥廷根物理学派,在哥廷根、在法兰克福、在爱丁堡他培养和影响了十余名年轻科学家,帮助他们获得诺贝尔奖.玻恩的成就使之当之无愧进入20世纪伟大物理教育家之前列. 相似文献

The article investigates the way in which Peter Mittelstaedt has been contributing to the philosophy of physics for half a century. It is shown that he pursues a path between rationalism and empiricism in the sense of Erhard Scheibe’s philosophy of the physicists. Starting from Kant’s a priori he gives a rational reconstruction of the conceptual revolutions of 20th century physics. The central topic of his philosophy of physics is the quest for semantic self-consistency, which for quantum mechanics is a hard nut to crack. 相似文献

In late 1900, the German theoretical physicist Max Planck derived an expression for the spectrum of black-body radiation. That derivation was the first step in the introduction of quantum concepts into physics. But how did Planck think about his result in the early years of the twentieth century? Did he assume that his derivation was consistent with the continuous energies inherent in Maxwellian electrodynamics and Newtonian mechanics? Or did he see the beginnings, however tentative and uncertain, of the quantum revolution to come? Historians of physics have debated this question for over twenty years. In this article, I review that debate and, at the same time, present Planck's achievement in its historical context. 相似文献

Ludvig Lorenz was Denmark's first theoretical physicist of international recognition. Despite his important contributions to a broad range of experimental and theoretical physics, he generally appears as a somewhat peripheral figure in histories of late‐nineteenth‐century physics and is completely overshadowed by his near‐namesake H. A. Lorentz. Herein, a selected number of Lorenz's works is introduced with an eye on those which are still of relevance to modern physics and today eponymously associated with his name. These contributions are known as the Lorenz number, the Lorenz gauge, the Lorenz–Lorentz law or formula, and the Lorenz–Mie scattering theory. 相似文献

Arnold Sommerfeld (1868-1951) founded one of the most influential schools of twentieth-century theoretical physics. His favored specialty was atomic theory, and a world-wide community of physicists was introduced to this field by his legendary textbook, Atomic Structure and Spectral Lines. The names of his students read like a Who's Who of the pioneers in modern physics Peter Debye, Peter Paul Ewald, Wolfgang Pauli, Werner Heisenberg, Hans A. Bethe - to name only the most prominent. In retrospect, the success of Sommerfeld's school of modern theoretical physics tends to overshadow its less glorious beginnings. A century ago, theoretical physics was not yet considered as a distinct discipline. In this article I emphasize more the haphazard beginnings than the later achievements of Sommerfeld's school, which mirrored the state of theoretical physics before it became an independent discipline. 相似文献

One century ago this year the Dutch experimental physicist Heike Kamerlingh Onnes (1853–1926) was awarded the Nobel Prize in Physics for his work in low-temperature physics, in particular for his production of liquid helium. I trace the route to his Nobel Prize within the context of his and his colleagues’ research in his laboratory at the University of Leiden, and in light of his nominators and the nominations he received in the five years 1909–1913. 相似文献

This essay surveys the work of John Stewart Bell, one of the great physicists of the twentieth century. Section 1 is a brief biography, tracing his career from working-class origins and undergraduate training in Belfast, Northern Ireland, to research in accelerator and nuclear physics in the British national laboratories at Harwell and Malvern, to his profound research on elementary particle physics as a member of the Theory Group at CERN and his equally profound "hobby" of investigating the foundations of quantum mechanics. Section 2 concerns this hobby, which began in his discontent with Bohr's and Heisenberg's analyses of the measurement process. He was attracted to the program of hidden variables interpretations, but he revolutionized the foundations of quantum mechanics by a powerful negative result: that no hidden variables theory that is "local" (in a clear and well-motivated sense) can agree with all the correlations predicted by quantum mechanics regarding well-separated systems. He further deepened the foundations of quantum mechanics by penetrating conceptual analyses of results concerning measurement theory of von Neumann, de Broglie and Bohm, Gleason, Jauch and Piron, Everett, and Ghirardi-Rimini-Weber. Bell's work in particle theory (Section 3) began with a proof of the CPT theorem in his doctoral dissertation, followed by investigations of the phenomenology of CP-violating experiments. At CERN Bell investigated the commutation relations in current algebras from various standpoints. The failure of current algebra combined with partially conserved current algebra to permit the experimentally observed decay of the neutral pi-meson into two photons stimulated the discovery by Bell and Jackiw of anomalous or quantal symmetry breaking, which has numerous implications for elementary particle phenomena. Other late investigations of Bell on elementary particle physics were bound states in quantum chromodynamics (in collaboration with Bertlmann) and estimates for the anomalous magnetic moment of the muon (in collaboration with de Rafael). Section 4 concerns accelerations, starting at Harwell with the algebra of strong focusing and the stability of orbits in linear accelerators and synchrotrons. At CERN he continued to contribute to accelerator physics, and with his wife Mary Bell he wrote on electron cooling and Beamstrahlung. A spectacular late achievement in accelerator physics was the demonstration (in collaboration with Leinaas) that the effective black-body radiation seen by an accelerated observer in an electromagnetic vacuum - the "Unruh effect" - had already been observed experimentally in the partial depolarization of electrons traversing circular orbits. 相似文献

Heike Kamerlingh Onnes (1853-1926), born a century and a half ago, was a major protagonist in
the so-called Second Golden Age of Dutch Science. He devoted his career to the emerging field
of low-temperature physics. His particular concern was to test the theories of his older compatriot
Johannes Diderik van der Waals (1837-1923) by creating a style of research that was characterized
by meticulous planning, precise measurement, and constant improvement of techniques and
instruments. He made numerous contributions to low-temperature physics, but I focus on his liquefaction
of helium, for which he received the Nobel Prize in Physics for 1913, and on his discovery
of superconductivity. He became known internationally as le gentleman du zéro absolu. 相似文献

Historians of science have analyzed in detail the conceptual transformations that gave physics its modern character in the first half of the twentieth century. Rarely provided in these narratives, however, is a feeling for the global scene of the physics community. How many publishing physicists were there around 1900? How many in 1925 or 1939? Did most physicists publish as single authors or in teams, and how did they compare with chemists or mathematicians in terms of scientific collaborations? What are the links between these disciplines? I propose to undertake such a global analysis of the trends that can be captured through a bibliometric analysis of hundreds of thousands of scientific papers and the more than one million references in them. 相似文献

Quaternions, objects consisting of a scalar and a vector, sound like a mysterious concept from the past. In the nineteenth century, the theory of quaternions was praised as one of the most brilliant achievements in mathematical physics. The originator of this theory, Hamilton, surely one of the greatest scientists in that area, spent about 18 years in discussing all kinds of algebraic and geometric properties of quaternions. His research was communicated to the Philosophical Magazine in three series of papers comprising a total of 29 contributions. In this commentary, these three series of papers are revisited concentrating primarily on the algebraic properties of quaternions. 相似文献
