Book Description
“George Ellery Hale [1868-1938] is the subject of this impressive biography... Wright charts Hale’s steady progress towards leadership in the nascent field of astrophysics from his childhood experiments at home in Chicago, through student days at MIT, to his first observatory at Kenwood, all of which demonstrate his passion for unravelling the secrets of nature through the then new medium of spectroscopy. This enthusiasm led him into contact with most of his peers both in America and beyond (Lockyer, Huggins, Pickering, Rowland, and many more), many of whom remained close associates and correspondents for years after. Probably this sense of community made Hale so active in the organization of science, including the formation of the AAS [American Astronomical Society], the IAU [International Astronomical Union], and ICSU [International Council of Scientific Unions]. It also gave him the contacts to give the Astrophysical Journal such a good start in 1895. Perhaps the greatest debt we owe Hale is for his relentless drive towards the creation of ever bigger and better facilities, starting with the still unsurpassed Yerkes refractor, continuing with the solar telescopes on Mt. Wilson and then the 60- and 100-inch telescopes on the same peak, and concluding with the 200-inch [at Mt. Palomar]... Scientifically, Hale’s lifelong affair with the Sun brought him success in the detection of magnetic fields and early studies of surface activity by means of the spectroheliograph he developed, and for which he was duly fêted, and the frustrations of trying to record the corona. But these were early successes and as astropolitics and finance took an ever increasing share of his time, he was able to contribute less than he would have liked. Part of the problem was the illness, with both physical and mental symptoms, which progressively plagued the life of this hyperactive polymath; it is sad to note his decline which prevented him playing a fuller part in the creation of what was to become his memorial... this [biography] is something of a classic on one of astronomy’s giants.” — David Strickland, The Observatory “This important biography is well written and is highly recommended.” — A. E. Covington, Journal of the Royal Astronomical Society of Canada “[An] outstanding biography of this most remarkable man... Helen Wright has done a superb job of tracing Hale’s development not only of new and powerful instruments and of his important discoveries of sunspot magnetic fields and the law of reversing polarities, but also of the embryonic state of American science in the early days of this century... an authoritative biography of one of the most influential men of science this country has produced. The hook will bring to contemporary scientists and historians the story of this unique astronomer whose life is of such special interest to the Caltech community.” — Allan Sandage, Caltech Magazine (formerly Engineering and Science) “Helen Wright gives a detailed account of the life and almost frantic activities of this remarkable scientific leader... In summarizing astrophysical events of the years 1880 to 1950... Wright has provided a useful and fascinating account of scientific development that led to the preeminence of the United States.” — Thornton Page, Science “In writing the story of Hale’s origins, career and bequest to posterity Helen Wright has richly served her fellow astronomers. No one else could have done so well. Her account preserves an admirable balance in presenting Hale not only as a doer but also as a dreamer... Miss Wright’s excellent biography covers the highlights of his career... Miss Wright’s book is highly authentic.” — Harlow Shapley, Scientific American Published under license from Springer Science+Business Media, LLC, part of Springer Nature

The Cambridge History of Science: Volume 8, Modern Science in National, Transnational, and Global Context PDF Author: Hugh Richard Slotten
Publisher: Cambridge University Press
ISBN: 1108863353
Category : Technology & Engineering
Languages : en
Pages : 1046

Book Description
This volume in the highly respected Cambridge History of Science series is devoted to exploring the history of modern science using national, transnational, and global frames of reference. Organized by topic and culture, its essays by distinguished scholars offer the most comprehensive and up-to-date nondisciplinary history of modern science currently available. Essays are grouped together in separate sections that represent larger regions: Europe, Africa, the Middle East, South Asia, East and Southeast Asia, the United States, Canada, Australia, New Zealand, Oceania, and Latin America. Each of these regional groupings ends with a separate essay reflecting on the analysis in the preceding chapters. Intended to provide a balanced and inclusive treatment of the modern world, contributors analyze the history of science not only in local, national, and regional contexts but also with respect to the circulation of knowledge, tools, methods, people, and artifacts across national borders.

The Life and Works of J. C. Kapteyn

The Life and Works of J. C. Kapteyn PDF Author: E. Robert Paul
Publisher: Springer Science & Business Media
ISBN: 9401119406
Category : Science
Languages : en
Pages : 107

Book Description
Among the most influential, world-renowned scientists during the early decades of the twentieth century was the Dutch astronomer Jacobus Cornelius Kapteyn (1851-1922). Kapteyn's influence resulted from and contributed to the golden age of Dutch science. In the words of the brilliant English astrophysicist, Arthur S. Eddington: `Holland has given many scientific leaders to the world: it is doubtful whether any other nation in proportion to its size can show so fine a record. J.C. Kapteyn was among the most distinguished of its sons -- a truly great astronomer'. The present text is an English translation of Kapteyn's 1928 (Dutch) biography by his daughter Henrietta Hertzsprung-Kapteyn. While the original biography suffers from -- but in many ways is also enriched by -- the emotional excesses of a loving daughter writing of her famous father, this new translation provides an annotated assessment of Kapteyn as family man, scientist and world leader. This new volume also opens up to a much wider reading public many of the enormously rich contributions, not only of Kapteyn the man but also of the Dutch, to the emergence of astronomy as a major intellectual force in the world. Perhaps equally important, the translated biography reproduces many biographical and technical details from Kapteyn's correspondence with numerous other scientists and scholars. Access to the Kapteyn biography becomes an archival treasure for future studies dealing with Kapteyn himself, as well as with the history of both modern and Dutch astronomy and with the rise of international astronomy.

The Ethereal Aether

The Ethereal Aether PDF Author: Loyd S. Swenson
Publisher: University of Texas Press
ISBN: 0292758367
Category : Science
Languages : en
Pages : 396

Book Description
The Ethereal Aether is a historical narrative of one of the great experiments in modern physical science. The fame of the 1887 Michelson-Morley aether-drift test on the relative motion of the earth and the luminiferous aether derives largely from the role it is popularly supposed to have played in the origins, and later in the justification, of Albert Einstein’s first theory of relativity; its importance is its own. As a case history of the intermittent performance of an experiment in physical optics from 1880 to 1930 and of the men whose work it was, this study describes chronologically the conception, experimental design, first trials, repetitions, influence on physical theory, and eventual climax of the optical experiment. Michelson, Morley, and their colleague Miller were the prime actors in this half-century drama of confrontation between experimental and theoretical physics. The issue concerned the relative motion of “Spaceship Earth” and the Universe, as measured against the background of a luminiferous medium supposedly filling all interstellar space. At stake, it seemed, were the phenomena of astronomical aberration, the wave theory of light, and the Newtonian concepts of absolute space and time. James Clerk Maxwell’s suggestion for a test of his electromagnetic theory was translated by Michelson into an experimental design in 1881, redesigned and reaffirmed as a null result with Morley in 1887, thereafter modified and partially repeated by Morley and Miller, finally completed in 1926 by Miller alone, then by Michelson’s team again in the late 1920s. Meanwhile Helmholtz, Kelvin, Rayleigh, FitzGerald, Lodge, Larmor, Lorentz, and Poincaré—most of the great names in theoretical physics at the turn of the twentieth century—had wrestled with the anomaly presented by Michelson’s experiment. As the relativity and quantum theories matured, wave-particle duality was accepted by a new generation of physicists. The aether-drift tests disproved the old and verified the new theories of light and electromagnetism. By 1930 they seemed to explain Einstein, relativity, and space-time. But in historical fact, the aether died only with its believers.
