Book Description

Publication Date: September 30, 1996 | ISBN-10: 0691026238 | ISBN-13: 978-0691026237

For over three millennia, most people could understand the universe only in terms of myth, religion, and philosophy. Between 1920 and 1970, cosmology transformed into a branch of physics. With this remarkably rapid change came a theory that would finally lend empirical support to many long-held beliefs about the origins and development of the entire universe: the theory of the big bang. In this book, Helge Kragh presents the development of scientific cosmology for the first time as a historical event, one that embroiled many famous scientists in a controversy over the very notion of an evolving universe with a beginning in time. In rich detail he examines how the big-bang theory drew inspiration from and eventually triumphed over rival views, mainly the steady-state theory and its concept of a stationary universe of infinite age. In the 1920s, Alexander Friedmann and Georges Lemaitre showed that Einstein's general relativity equations possessed solutions for a universe expanding in time. Kragh follows the story from here, showing how the big-bang theory evolved, from Edwin Hubble's observation that most galaxies are receding from us, to the discovery of the cosmic microwave background radiation. Sir Fred Hoyle proposed instead the steady-state theory, a model of dynamic equilibrium involving the continuous creation of matter throughout the universe. Although today it is generally accepted that the universe started some ten billion years ago in a big bang, any readers may not fully realize that this standard view owed much of its formation to the steady-state theory. By exploring the similarities and tensions between the theories , Kragh provides the reader with indispensable background for understanding much of today's commentary about our universe.

From Library Journal

Today we take it for granted that the universe began with a big bang. But this has not always been the case. Prior to its wide acceptance as the most probable origin of our universe, the big bang theory had to win over the rival viewpoint of the steady-state theory. Between 1920 and 1970, cosmology became a bonafide branch of physics. Up to this time, people viewed the birth of the universe from the standpoint of religion, philosophy, and myth. Kragh (science history, Univ. of Oslo) presents a detailed, scholarly history of this period of scientific cosmological development, discussing the primary scientists involved in both arguments. Undoubtedly, Kragh's book offers a significant accounting of the debates, discoveries, and events surrounding present-day cosmological theories. Yet the detailed mathematical concepts involved will not be easily understood by the general reader. Recommended primarily for academic libraries, though comprehensive history of science collections in public libraries would benefit as well.?Gloria Maxwell, Kansas City P.L.

Review

"An exhilarating read-and not just for cosmologists. For although Kragh has produced a thoroughly scholarly work, he is nevertheless an excellent writer and his book could easily be enjoyed by anyone who is fascinated by the evolution of big scientific ideas. And they don't come much bigger than the origin, evolution, and fate of the Universe." -- Marcus Chown, New Scientist

"As one who has been intimately involved with the subject, I thoroughly appreciated reading this work.... There are still a few left who believe that science advances relentlessly in a straight line. The actual zigzag path is beautifully illuminated in this book." -- Hermann Bondi, Nature

"[A] masterful interpretation of modern cosmology's emergence." -- Karl Hufbauer, Physics Today

"[An] excellent book . . . [a] thorough and detailed understanding. . . has enabled Kragh to write. . . enjoyable descriptions of complex issues. . . . It is difficult to imagine a more complete and scholarly account of this epoch of cosmological history." -- Bernard Lovell, The Times Literary Supplement

"[An] insightful, thoroughly researched treatment of the intellectual development of modern cosmology." -- Woodruff T. Sullivan III, Science

The ultimate validation of the bigbang theory makes for a fascinating book. Kragh [tells] the story in comprehesive and compelling detail. -- Jack Zirker, National Optical Astronomy Observatories

5.0 out of 5 stars An outstanding book, June 19, 2000

By 

Alexander Vilenkin (Boston, Massachusetts) - See all my reviews

This review is from: Cosmology and Controversy (Paperback)

This book is a detailed and masterful description of the history of big bang cosmology, from its emergence in the 1940s to its observational validation in the 1960s. It is also an inquiry into the nature of the scientific progress -- an equally fascinating subject. The book is complete with personal histories of the main participants and gives unique insights into their motivation and the evolution of their views, often obtained through personal correspondence with the author. Being a cosmologist myself, I can add that the book is written with a deep understanding of the subject.

This review is from: Cosmology and Controversy (Paperback)

Although a bit dated, Helge Kragh is doubtless one of the top Historians of Science dealing with Cosmology. I would recommend this very readable book to anyone interest in the origin of the universe, current thinking about where it is headed, and interpretations of trends amongst the ideas and research of the top people in the field. Kragh's command of the field is top-notch, judging from his references (yep, it is a HE, from Denmark). You'll have this on your reference shelf for years to come.

This review is from: Cosmology and Controversy (Paperback)

This very good book is a history of scientific cosmology from its initiation with Einstein's development of General Relativity to the establishment of the Big Bang theory, approximately from about 1920 to 1970. As Kragh demonstrates, cosmology in the modern, scientific sense begins with Einstein's publication of the Theory of General Relativity which made possible the development of models of the universe. Simple models developed originally by Einstein himself and the Dutch astronomer De Sitter depicted static universes and were based the existing astronomical data suggesting a static universe. The accumulation of astronomical data indicating a larger and expanding universe plus the exploration of models led to alternative models, notably those of the Belgian astrophysicist and priest George Lemaitre, the first systematic development of the Big Bang hypothesis. Kragh discusses very nicely development of these ideas, alternative approaches developed by the small number of other investigators interested in cosmology, and the interaction between theory and observation. He then describes the post-WWII emergence of the major alternative to the Big Bang hypothesis, the Steady State theory developed by the British scientists Hoyle, Gold, Bondi. The development of this theory, the major expansion of the Big Bang theory by American investigators led by George Gamow, the interaction of theory and observational work, and the general nature of the controversy is delineated very well by Kragh in an account that looks both at the primary literature and the general context. Kragh discusses philosophical issues, different national traditions, the impact of new methods in astronomy, and the impact of other developments in physics. For example, in the late 1950s, there was a revival of interest in General Relativity and the emergence of experimental methods to evaluate General Relativity. The success of General Relativity in these experiments gave credance to cosmological models, like the Big Bang, based on General Relativity. Kragh's discussion of the interaction of theory and experiment in the resolution of the controversy in favor of the Big Bang theory is simply excellent.

This book can be seen to some extent as a case study testing Kuhn's famous model of scientific progression. While Kragh uses Kuhnian terms like paradigm, his overall conclusion is that Kuhn's model doesn't really describe the way this major scientific development unfolded. Kragh's narrative indicates something much more like Kuhn's "normal science" as the predominant mode of scientific progression.

The ideal reader for this book is a cosmologist or physicist with considerable knowledge of cosmology. Kragh presents quite a bit of the narrative by showing the actual equations. Nonetheless, this book is definitely intelligible in a general way to readers with only a vague knowledge of cosmology (like me). Kragh is a very good writer who is careful to provide narrative accessible to general readers. I, for example, don't have the physics to understand cosmology in depth but I was able to get a good qualitative sense of the important developments and historical process.
