ISBN: 9789810223694
Category : Science
Languages : en
Pages : 784

Book Description
In this important volume, major events and personalities of 20th century physics are portrayed through recollections and historiographical works of one of the most prominent figures of European science. A former student of Enrico Fermi, and a leading personality of physical research and science policy in postwar Italy, Edoardo Amaldi devoted part of his career to documenting, both as witness and as historian, some significant moments of 20th century science. The focus of the book is on the European scene, ranging from nuclear research in Rome in the 1930s to particle physics at CERN, and includes biographies of physicists such as Ettore Majorana, Bruno Touschek and Fritz Houtermans.Edoardo Amaldi (Carpaneto, 1908 - Roma, 1989) was one of the leading figures in twentieth century Italian science. He was conferred his degree in physics at Rome University in 1929 and played an active role (as a member of the team of young physicists known as ?the boys of via Panisperna?) in the fundamental research on artificial induced radioactivity and the properties of neutrons, which won the group's leader Enrico Fermi the Nobel Prize for physics in 1938. Following Fermi's departure for the United States in 1938 and the disruption of the original group, Amaldi took upon himself the task of reorganising the research in physics in the difficult situation of post-war Italy. His own research went from nuclear physics to cosmic ray physics, elementary particles and, in later years, gravitational waves. Active research was for him always coupled to a direct involvement as a statesman of science and an organiser: he was the leading figure in the establishment of INFN (National Institute for Nuclear Physics) and has played a major role, as spokesman of the Italian scientific community, in the creation of CERN, the large European laboratory for high energy physics. He also actively supported the formation of a similar trans-national joint venture in space science, which gave birth to the European Space Agency. In these and several other scientific organisations, he was often entrusted with directive responsibilities. In his later years, he developed a keen interest in the history of his discipline. This gave rise to a rich production of historiographic material, of which a significant sample is collected in this volume.

Book Description
This is an open access book available under the terms of a CC BY-NC-ND 4.0 International licence. It is free to read on the Oxford Academic platform and offered as a free PDF download from OUP and selected open access locations. Following the centenary of the International Union of Pure and Applied Physics, this volume features contributions from leading science historians from around the world on the changing roles of the institution in international affairs from its foundation in 1922 to the present. The case studies presented in this volume show the multitude of functions that IUPAP had and how these were related to the changing international political contexts. The book is divided into three parts. The first discusses the interwar period demonstrating how the exclusion of communities of the Central Powers from international scientific institutions imposed by victorious allied countries made IUPAP ineffective until the end of World War II. The second part analyzes the changing roles assumed by IUPAP starting from its complete renovation after World War II. Case studies covering the role of IUPAP in physics education, in metrology, in joint commissions with other unions and in defining the complex relations between pure and applied physics provide examples of IUPAP's impact on the world of science. Part III squarely addresses the science diplomacy aspects of IUPAP during the Cold War highlighting the importance of IUPAP in furthering diplomatic goals and explaining the origin of the pursuit of the free circulation of scientists as the activity that characterized the main function of international unions during the Cold War. Highlighting how often scientific agendas and political imperatives were entangled in the activities of IUPAP, the book analyzes the work of the Union as exercises of science diplomacy, thus contributing to the current debate on the use of science and technology in international relations.

Controversy and Consensus: Nuclear Beta Decay 1911–1934

Controversy and Consensus: Nuclear Beta Decay 1911–1934 PDF Author: Carsten Jensen
Publisher: Springer
ISBN: 3034884443
Category : Science
Languages : en
Pages : 232

Book Description
In 1920s, a long-lasting controversy on the interpretation of nuclear beta spectrum arose between Lise Meitner and Charles Drummond Ellis. This controversy, and the reactions from the contending parties when it was settled, reflect clearly the difference between the scientific communities in Berlin and Cambridge at that time. The Meitner-Ellis controversy ended in 1929, and it left an anomaly that attracted leading theoretical physicists. A new dispute, this time between Niels Bohr and Wolfgang Pauli, broke out. It concerned the explanation of the continuity of the primary beta particles and dominated the discussions for the next five years. Pauli argued for a new particle, and Bohr for a new theory; both suggestions were radical steps, but they reflected two different ways of doing physics.

The Physicists

The Physicists PDF Author: Daniel J. Kevles
Publisher: Harvard University Press
ISBN: 9780674666566
Category : History
Languages : en
Pages : 548

Book Description
This magnificent account of the coming of age of physics in America has been heralded as the best introduction to the history of science in the United States. Unsurpassed in its breadth and literary style, Kevles's account portrays the brilliant scientists who became a powerful force in bringing the world into a revolutionary new era. The book ranges widely as it links these exciting developments to the social, cultural, and political changes that occurred from the post-Civil War years to the present. Throughout, Kevles keeps his eye on the central question of how an avowedly elitist enterprise grew and prospered in a democratic culture. In this new edition, the author has brought the story up to date by providing an extensive, authoritative, and colorful account of the Superconducting Super Collider, from its origins in the international competition and intellectual needs of high-energy particle physics, through its establishment as a multibillion-dollar project, to its termination, in 1993, as a result of angry opposition within the American physics community and the Congress.

Genius in the Shadows

Genius in the Shadows PDF Author: William Lanouette
Publisher: Skyhorse
ISBN: 1628734779
Category : Biography & Autobiography
Languages : en
Pages : 691

Book Description
Well-known names such as Albert Einstein, Enrico Fermi, J. Robert Oppenheimer, and Edward Teller are usually those that surround the creation of the atom bomb. One name that is rarely mentioned is Leo Szilard, known in scientific circles as “father of the atom bomb.” The man who first developed the idea of harnessing energy from nuclear chain reactions, he is curiously buried with barely a trace in the history of this well-known and controversial topic. Born in Hungary and educated in Berlin, he escaped Hitler’s Germany in 1933 and that first year developed his concept of nuclear chain reactions. In order to prevent Nazi scientists from stealing his ideas, he kept his theories secret, until he and Albert Einstein pressed the US government to research atomic reactions and designed the first nuclear reactor. Though he started his career out lobbying for civilian control of atomic energy, he concluded it with founding, in 1962, the first political action committee for arms control, the Council for a Livable World. Besides his career in atomic energy, he also studied biology and sparked ideas that won others the Nobel Prize. The Salk Institute for Biological Studies in La Jolla, California, where Szilard spent his final days, was developed from his concepts to blend science and social issues.

Book Description
and less as the emanation unden\'ent radioactive decay, and it became motion less after about 30 seconds. Since this process was occurring very rapidly, Hahn and Sackur marked the position of the pointer on a scale with pencil marks. As a timing device they used a metronome that beat out intervals of approximately 1. 3 seconds. This simple method enabled them to determine that the half-life of the emanations of actinium and emanium were the same. Although Giesel's measurements had been more precise than Debierne's, the name of actinium was retained since Debierne had made the discovery first. Hahn now returned to his sample of barium chloride. He soon conjectured that the radium-enriched preparations must harbor another radioactive sub stance. The liquids resulting from fractional crystallization, which were sup posed to contain radium only, produced two kinds of emanation. One was the long-lived emanation of radium, the other had a short life similar to the emanation produced by thorium. Hahn tried to separate this substance by adding some iron to the solutions that should have been free of radium, but to no avail. Later the reason for his failure became apparent. The element that emitted the thorium emanation was constantly replenished by the ele ment believed to be radium. Hahn succeeded in enriching a preparation until it was more than 100,000 times as intensive in its radiation as the same quantity of thorium.

Languages : en
Pages : 416

Book Description
Beginning with a couple of essays dealing with the experimental and mathematical foundations of physics in the work of Henry Cavendish and Joseph Fourier, the volume goes on to consider the broad areas of investigation that constituted the central foci of the development of the physics discipline in the nineteenth century: electricity and magnetism, including especially the work of Michael Faraday, William Thomson, and James Clerk Maxwell; and thermodynamics and matter theory, including the theoretical work and legacy of Josiah Willard Gibbs, some experimental work relating to thermodynamics and kinetic theory of Heinrich Hertz, and the work of Felix Seyler-Hoppe on hemoglobin in the neighboring field of biophysics/biochemistry. Moving on to the beginning of the twentieth century, a set of three articles on Albert Einstein deal with his early career and various influences on his work. Finally, a set of historiographical issues important for the history of physics are discussed, and the chronological conclusion of the volume is an article on the Solvay Conference of 1933. For physicists interested in the history of their discipline, historians and philosophers of science, and graduate students in these and related disciplines.

Scientific Papers of Arthur Holly Compton

Scientific Papers of Arthur Holly Compton PDF Author: Arthur Holly Compton
Publisher: University of Chicago Press
ISBN: 9780226114309
Category : History
Languages : en
Pages : 822

Book Description
Arthur Holly Compton was one of the great leaders in physics of the twentieth century. In this volume, Robert S. Shankland, who was once a student of Compton's, has collected and edited the most important of Professor Compton's papers on X-rays—the field of his greatest achievement—and on other related topics. Compton entered the field of X-ray research in 1913 and carried on active work until the 1930s, when he began to specialize in cosmic rays. During the years when Compton was an active leader in X-ray research, he made many notable contributions which are reflected in the papers presented here. He was the first to prove several important optical properties of X-rays, including scattering, complete polarization, and total reflection. He was also the first, with his student R. L. Doan, to use ruled gratings for the production of X-ray spectra. Professor Compton's greatest discovery, for which he was awarded a Nobel Prize in 1927, was the Compton Effect. This was the outgrowth of experiments he had initiated during a year at Cambridge in 1919-20. He did the major portion of these experiments at Washington University in St. Louis during the period 1920-24. His work demonstrated that in the scattering of X-rays by electrons, the radiation behaves like corpuscles, and that the interaction between the X-ray corpuscles and the electrons in the scatter is completely described by the principles of the conservation of energy and momentum for the collisions of particles. In his introduction, Professor Shankland gives a historical account of the papers, narrates Professor Compton's early scientific career, and shows how he arrived at a quantum explanation of the Compton scattering after eliminating all classical explanations.
