Hardback. Condizione: New. Illustrated. The authors of this volume have been intimately connected with the conception of the Big Bang model since 1947. Following the late George Gamov's ideas in 1942 and more particularly in 1946 that the early universe was an appropriate site for the synthesis of the elements, they became deeply involved in the question of cosmic nucleosynthesis and particularly the synthesis of the light elements. In the course of this work they developed a general relativistic model of the expanding universe with physics folded in, which led in a progressive, logical sequence to our prediction of the existence of a present cosmic background radiation some seventeen years before the observation of such radiation was reported by Penzias and Wilson. In addition, they carried out with James W. Follin, Jr., a detailed study of the physics of what was then considered to be the very early universe, starting a few seconds after the Big Bang, which still provides a methodology for studies of light element nucleosynthesis. Because of their involvement, they bring a personal perspective to the subject. They present a picture of what is now believed to be the state of knowledge about the evolution of the expanding universe and delineate the story of the development of the Big Bang model as they have seen and lived it from their own unique vantage point.

Original wrappers. GOOD copy, only, because of some problems with the spine (see pic). [++]  Written with Robert Herman, this is a deep and historically penetrating review of the "distribution of the elements" issue. Its 180-item bibliography is particularly useful.  Also included in this same issue is D. Ter Haar's "Cosmogonical Problems and Stellar Energy", an excellent review covering the first section of the issue (pp 119-152), and also including another very useful *chronological bibliography*. Wonderful paper.

"The Origin of the Chemical Elements," the great Alpher/Bethe/Gamow paper and all-time insider-bad-joke, coming in the 1 April 1948 issue of the Physical Review vol 73, April 1, 1948, pp 803-804 in the issue of pp 559-813. This is the original issue, removed from a larger bound volume. Crisp copy. Good condition. [++] (The joke being that Gamow added Hans Bethe so that he could have a "B" for the paper's authors being "ABC" with the "G" of "Gamow" transliterated to its Greek counterpart, a "C".) This issue contains the letter to the editor which announced Gamow's (et alia) theory on background radiation and the formulation of the "Big Bang". This is one of the great discoveries of the century--it didn't have the implications of the (troublesome and tiresome) James Watson's DNA discovery, but almost nothing else did, either, but it certainly had other enormous intellectual and philosophical (and scientific of course) ramifications. [++] "In 1948 [Gamow] predicted that all matter in the universe is in a state of general rotation about some distant center; at the same time he began developing his ideas on the origin and frequency distribution of the chemical elements, postulating that before the big bang there existed a primordial state of matter, ( ylem ) consisting of neutrons and their decay products, protons and electrons, mixed together in a sea of high-energy radiation the basic ingredients necessary for the formation of deuterons and heavier, and heavier nuclei as the universe subsequently expanded. Most of the detailed theoretical calculations were carried out by R. Alpher (assisted by R. Herman), which resulted in the well-know Alpher-Bethe-Gamow letter in Physical Review of 1 April 1948 [the paper offered here]. This work also led to the prediction of a residual blackbody radiation spectrum, the remnant from the primordial big bang corresponding to few degrees Kelvin. This radiation was first detected in early 1965 by A. A. Penzias and R. W. Wilson; much more definite evidence was found the following year by P. G. Roll and D. T. Wilkinson (in experiments initiated by R. R. Dicke and P. J. E. Peebles) at Princeton University."--Complete DSB online [++].

original wrappers. Condizione: Very Good. First edition. FIRST PRINTINGS OF THE FOUNDATIONAL PAPERS ON THE BIG BANG AND THE ORIGIN OF THE UNIVERSE. Including a fine copy of the famous "Alpha-Beta-Gamma" paper. The Origin of Chemical Elements: "With the experimental and theoretical information now available it is possible to give a tentative description of the structure and evolution of the universe." Physicist George Gamow "was interested in the Big Bang in relation to nucleosynthesis- the formation of atomic nuclei. Gamow wanted to see whether nuclear physics and the Big Bang could explain the observed atomic abundances," specifically, "whether the early moments of the Big Bang could be responsible for our universe being dominated by hydrogen and helium." With his graduate student Ralph Alpher, Gamow began constructing an ingenius mathematical model that attempted to explain the nuclear processes that would have occurred at the conditions of the extreme heat of the very early universe. They "spent three years working through their calculations, questioning their assumptions, updating their cross-sections and refining their estimates. This was an extraordinary adventure. They were applying concrete physics to a previously vague Big Bang theory, attempting to mathematically model the conditions and events of the early universe. They were estimating initial conditions and applying the laws of nuclear physics to see how the universe evolved with time and how the processes of nucleosynthesis progressed." The result was a stunning success. With their model, Alpher and Gamow could predict the formation of hydrogen and helium in the observed proportions ( 99.99% of all atoms ) in the universe. "This result was the first major triumph for the Big Bang model since Hubble had observed and measured the redshifts of galaxies. "When Gamow and Alpher's paper, "The Origin of Chemical Elements" was being sent for publication in the April 1, 1948 issue (April Fool's Day) of the Physical Review, Gamow couldn't resist playing a little joke on the scientific community. Even though his good friend Hans Bethe contributed nothing to the paper, Gamow added his name to the list of authors so the readers could enjoy the sight of a paper authored by Alpher, Bethe, Gamow and appreciate the pun on the Greek letters alpha, beta, and gamma. One of the unintended consequences of this joke was that is stripped the young Alpher of much of the credit due to him, for the public naturally assumed that the famous Bethe and Gamow had now done all the work. "The Alpha-Beta-Gamma paper, as it became known, was a milestone in the Big Bang versus eternal universe debate. It showed that it was possible to do real calculations relating to the nuclear processes that might have occurred after a hypothetical Big Bang, and thus test this theory of creation. Big Bang supporters could now point to two pieces of evidence, the expansion of the universe and the abundance of hydrogen and helium, and show that they were entirely consistent with the Big Bang model of the universe."

Quarto, original wrappers. A FINE COPY. Expanding Universe and the Origin of Elements: "Birth of the Big Bang Model" -Particle Physics: One Hundred Years of Discovery FIRST EDITION IN ORIGINAL WRAPPERS of George Gamow's paper marking the beginning of the Big Bang Model. "The German physicist Carl Friedrich von Weizsacker had postulated in 1938 that most elements were formed in explosions similar to that taking place in Lemaitre's primeval atom, but he did not state clearly whether the birthplace was cosmological or stellar. The turning point came in 1946, when Gamow discussed quantitatively the role of nuclear processes in relativistic cosmologies. His brief 1946 paper on the expanding universe and the origin of elements marks the beginning of modern big bang theory" (Hetherington, Cosmology). Gamow, working with his graduate student Ralph Alpher, would spend the next two years developing his theory, culminating in the famous "Alpha-Beta-Gamma" paper (The Origin of Chemical Elements) of 1948. Particle Physics: One Hundred Years of Discoveries: "Gamow indication on the possibility to explain the observed chemical elements abundance-curve by assumption of unequilibrium process of elements formation during a limited interval of time. Birth of the Big Bang model." IN: The Physical Review, Vol. 70, Second Series, Numbers 7 and 8, October 1 and 15, 1946, pp. 572-3. Lancaster, PA and New York, NY: American Institute of Physics, 1946. Quarto, original wrappers neatly rebacked. Fine condition. WITH: -Ralph Alpher's "Neutron-capture theory of the formation and relative abundance of the elements": Alpher's doctoral dissertation, which presents the most detailed early exposition of the theory. He introduced the term "ylem" for the initial state of the universe, consisting only of neutrons. Gamow liked the term and often gave the impression that he had invented it. IN: The Physical Review, Vol 74, Second Series, Number 11, December 1, 1948, pp.1577-1589. Lancaster, PA and New York, NY: American Institute of Physics, 1948. Quarto, original wrappers; a fine copy. -The papers "Thermonuclear reactions in the expanding universe" (Alpher, Herman, Gamow; pp. 1198-99; November 1, 1948) and "On the relative abundance of the elements" (Alpher and Herman; pp. 1737-1742; December 15, 1948) report progress in the challenging problem of numerical computation of element build-up by neutron and proton capture.
