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.

As director of the Metallurgical Laboratory of the Manhattan Project at the University of Chicago, Arthur Holly Compton was a major participant in the research, production and testing of the first atomic bombs. In this memoir, he tells the story of the bomb’s development from the presentation of the project to President Roosevelt, through its planning, research, and building phases, to its use against Japan. From the perspective of the key position he held during World War II, Compton describes the project as a large-scale group effort leveraging the knowledge and talents of numerous scientists, industrialists and administrators all working as part of their nation’s war effort. “An absorbing and eminently readable account... packed with new information, enlivened with precious detail and illuminating insights into the minds and personalities of the chief actors in the drama... Mr. Compton tells, and tells well, the story of how, with his unflagging encouragement, the brilliant team under the late Enrico Fermi brought about the first nuclear chain reaction... [an] important book.” — Henry Guerlac, The New York Times Book Review “This book... is without doubt the most authoritative source available on many aspects of the atomic bomb project... Better than in most histories the real factors underlying one of mankind’s most important developments are set forth in this work... The story is a personal one, which... gives the book a Churchillian authenticity... No historian will ever dare to neglect this volume in writing the history of World War II. It is beautifully written, carefully documented, and thoroughly interesting from cover to cover.” — W.F. Libby, Science “For those who were in the project, it will mean many recollections. For those who were not, it should give an inkling of the character and capacity of many of the individuals, including Arthur Compton, who made success possible.” — Lieutenant General Leslie R. Groves, U.S. Army (Retired) “Atomic Quest is an absorbingly interesting story of the people who blazed the trail into the atomic frontier... In a lifetime filled with brilliant accomplishments, Arthur Compton’s four-year leadership in the quest for the atomic bomb was his grandest achievement... It is fortunate indeed that he returned to the fold long enough to set down in Atomic Quest a story that only he could tell.” — Richard L. Doan, American Journal of Physics “Dr. Compton is a thinking man whose reflections range far beyond the confines of his scientific work: indeed, the distinctive quality of his book lies in his ability to reconcile the atomic bomb and similar operations with his belief as a practicing Christian.” — John Barkham, Saturday Review Syndicate “It should be required reading for every American, for the free world... The narrative alone makes the book worth reading; its hopeful philosophy makes it mandatory reading.” — Robert S. Kleckner, Chicago Sunday Tribune “As... director of the Metallurgical Laboratory of the Manhattan Project, Dr. Compton has an important record to add to the annals of the beginning of the Atomic Age, for his was a personal and intimate connection with it.” — Kirkus “A leading physicist’s personal account of the wartime developments in atomic energy, culminating in the production of the atomic bomb.” — Henry L. Roberts, Foreign Affairs “Informal, anecdotal, packed with behind-the-scenes incidents and impressions... arrestingly interesting.” — George W. Gray, The Saturday Review “The most controversial part of the book is that which endeavors to foresee the future of a world faced with the threat of war with nuclear weapons and the inevitable widespread destruction that will accompany their use. Compton is convinced that war has actually thereby become obsolescent.” — Robert Bruce Lindsay, Physics Today “This book... is written for the layman, in clear, everyday English... it answers the questions that have arisen in the minds of all intelligent people concerning the physical, moral, social and religious implications of the Atomic Age which was so brutally and vividly thrust upon the world in 1945.” — Paul Jordan-Smith, Los Angeles Times
The forms taken by scientific writing help to determine the very nature of science itself. In this closely reasoned study, Charles Bazerman views the changing forms of scientific writing as solutions to rhetorical problems faced by scientists arguing for their findings. Examining such works as the early Philosophical Transactions and Newton's optical writings as well as Physical Review, Bazerman views the changing forms of scientific writing as solutions to rhetorical problems faced by scientists. The rhetoric of science is, Bazerman demonstrates, an embedded part of scientific activity that interacts with other parts of scientific activity, including social structure and empirical experience. This book presents a comprehensive historical account of the rise and development of the genre, and views these forms in relation to empirical experience.
This book focuses on the gradual formation of the concept of ‘light quanta’ or ‘photons’, as they have usually been called in English since 1926. The great number of synonyms that have been used by physicists to denote this concept indicates that there are many different mental models of what ‘light quanta’ are: simply finite, ‘quantized packages of energy’ or ‘bullets of light’? ‘Atoms of light’ or ‘molecules of light’? ‘Light corpuscles’ or ‘quantized waves’? Singularities of the field or spatially extended structures able to interfere? ‘Photons’ in G.N. Lewis’s sense, or as defined by QED, i.e. virtual exchange particles transmitting the electromagnetic force? The term ‘light quantum’ made its first appearance in Albert Einstein’s 1905 paper on a “heuristic point of view” to cope with the photoelectric effect and other forms of interaction of light and matter, but the mental model associated with it has a rich history both before and after 1905. Some of its semantic layers go as far back as Newton and Kepler, some are only fully expressed several decades later, while others initially increased in importance then diminished and finally vanished. In conjunction with these various terms, several mental models of light quanta were developed—six of them are explored more closely in this book. It discusses two historiographic approaches to the problem of concept formation: (a) the author’s own model of conceptual development as a series of semantic accretions and (b) Mark Turner’s model of ‘conceptual blending’. Both of these models are shown to be useful and should be explored further. This is the first historiographically sophisticated history of the fully fledged concept and all of its twelve semantic layers. It systematically combines the history of science with the history of terms and a philosophically inspired history of ideas in conjunction with insights from cognitive science.
To celebrate the intellectual achievement of the University of Chicago on the occasion of its centennial year, Edward Shils invited a group of notable scholars and scientists to reflect upon some of their own teachers and colleagues at the University.
This Encyclopedia examines all aspects of the history of science in the United States, with a special emphasis placed on the historiography of science in America. It can be used by students, general readers, scientists, or anyone interested in the facts relating to the development of science in the United States. Special emphasis is placed in the history of medicine and technology and on the relationship between science and technology and science and medicine.
Historically, the scientific method has been said to require proposing a theory, making a prediction of something not already known, testing the prediction, and giving up the theory (or substantially changing it) if it fails the test. A theory that leads to several successful predictions is more likely to be accepted than one that only explains what is already known but not understood. This process is widely treated as the conventional method of achieving scientific progress, and was used throughout the twentieth century as the standard route to discovery and experimentation. But does science really work this way? In Making 20th Century Science, Stephen G. Brush discusses this question, as it relates to the development of science throughout the last century. Answering this question requires both a philosophically and historically scientific approach, and Brush blends the two in order to take a close look at how scientific methodology has developed. Several cases from the history of modern physical and biological science are examined, including Mendeleev's Periodic Law, Kekule's structure for benzene, the light-quantum hypothesis, quantum mechanics, chromosome theory, and natural selection. In general it is found that theories are accepted for a combination of successful predictions and better explanations of old facts. Making 20th Century Science is a large-scale historical look at the implementation of the scientific method, and how scientific theories come to be accepted.
