The article reflects on the pursuit of pure science by the scientific community in the U.S. Indications showed that this endeavor is becoming more and more expensive. The authors of this paper attempts to defend one special kind of pure science, the physics of elementary particles. This is the branch of physics that looks for the fundamental constituents of matter. They proposed that in any intelligent discussion of the impact of pure science in society, it must be based upon knowledge of the development of modern physics and of the role of the study of elementary particles in the history of science.

The article presents the personal narrative of Otto R. Frisch and his involvement in nuclear fission. He considers his part in its study as a result of chance. He mentions his interest in physics started with his aunt Lise Meitner's influence. He attributes to chance his presence in the development of Niels Bohr's idea that the atomic nucleus was like a minute drop of liquid. He reveals his summary article on nuclear physics for the 1939 annual report on the progress of chemistry is again the result of chance.

The article reports on the rise of international cooperation among the scientific community in high energy physics. Before the Second World War broke out, and even before the advent of Adolf Hitler, the basic research enterprise in physics was concentrated in Western Europe, and to a remarkable extent in Germany. The great emigration to the U.S. of German and Italian physicists after 1933, followed by the spectacular contributions of American physics to the winning of the war brought about a marked shift in the center of gravity of physics research towards the U.S. after the Second World War.

PHYSICISTS ,PHILOSOPHY ,QUANTUM theory ,PHYSICS ,THEORY (Philosophy) ,BIOLOGY ,PHYSICAL sciences ,CAREER development - Abstract
The article aims to describe the philosophy of physicist Neils Bohr. The author stated that Bohr's philosophy falls into three parts, one that which he understands, one which he did not understand, but he felt it was clear to Bohr, and one that Bohr himself saw only dimly. He also stated that Bohr never brought up to his philosophy as his own and that he used to speak of it as a whole lesson to be illustrated from quantum mechanics. Bohr's philosophical ideas were not originally inspired by physics, but the aspects of the new theory suited his philosophy well. The author also cited Bohr's interests including biology and quantum physics and as well his career developments.

The article focuses on the discovery of the first self-sustained nuclear chain reaction. It talks about the performance of the experiment conducted by physicist George Weil, who had withdrawn the cadmium control rod and by his action has unleashed and then controlled the energy of the atom. Accordingly, the experiment was a tribute to physicist Enrico Fermi, with whom, more than to any other one person, the success of the experiment was due. Fermi had been working with uranium for many years, and in 1934 he had bombarded uranium with neutrons and produced what had appeared to be element 93 and element 94.

The article presents the author's comments on the philosophy of science in the Soviet Union. The author notices that in spite of the clear advances in various sectors of Soviet science and the much publicized recognition and even overstatement of Soviet attainments on the part of some who before had denied the very possibility of high-level Soviet accomplishment, the tendency persists to view the dynamics of Soviet science simplistically in terms of what has happened in genetics and to dismiss the contrary evidence of Soviet progress in the physical sciences as the result of a special dispensation from the Soviet leadership. Thus, the author holds that Soviet science is indeed compatible with totalitarianism, in fact, it has grown into a strong knowledge that the world is worried of.

The article focuses on atomic energy programs in the U.S. in 1950. The production of uranium 235 and plutonium was at the highest. Atomic weapons and fissionable material were produced at the rate authorized by the U.S. President for 1950. Progress on the nuclear reactor development program are discussed. Several nuclear facilities were constructed. The Atomic Energy Commission (AEC) supported research developments in physical sciences, established fellowship programs, considered ways to urge private financing of real estate development and completed its inventory and cost appraisal of its plant and equipment. A special panel was appointed to study the security system by the AEC. A working committee was established to evaluate technological information useful to industry.

The article explores the status of the physicists, specifically the merits and perils associated with the profession, as of mid-twentieth century. Contributions of physicists throughout the world include the universal distribution of electric light and power by Michael Faraday, the discovery of X-ray machines which makes diagnosis of internal injuries easier and faster, and the establishment of instantaneous wireless communication. It is inferred that projects in which the physicists played a prominent role were successful such as the primitive radar equipment which enabled a pitifully small number of Spitfire pilots to win the Battle of Britain.

The article presents a discussion on radiation chemistry. It also cites a brief history of radiation chemistry which started in 1942 when a group of physicists met in Chicago, Illinois to outline a chemical attack on atomic energy. Radiation chemistry or photo-chemistry is a highly essential phase of atomic energy development. It also cites the studies conducted on the effects of high-energy radiation which resulted in the finding that chemical elements alone were chemically insensitive. It also presents the new types of radiation and examines the effects of high-energy radiation on biological materials.

ACADEMIC dissertations ,SOCIAL sciences education ,PHYSICAL sciences ,POLITICAL rights ,CONSTITUTIONAL history ,PERIODICALS - Abstract
This article presents a comparative study of the determination of Ph.D. dissertations in the physical and social sciences. Physicists are the most likely to cite their own dissertations and also the most likely to cite dissertations from international sources. Political scientists are the most likely to avail themselves of findings outside the immediate locale of the citer. In both the physical and social sciences approximately 70 percent of the citations refer to dissertations which are cited within five years of their approval. No similar studies exist for political science and the physical sciences, but the existent data suggest the possible hypothesis that the dissemination of information in the social science journals is more dependent upon the relationship between the doctoral origins of journal editors and contributors than is the case in the physical science. Political scientists are the most likely to avail themselves of findings outside the immediate locale of the citer, 60.9 percent, with physicists being the least likely a 18.4 percent.

SOCIAL sciences ,NATURAL history ,SOCIOLOGY ,SOCIAL scientists ,PHYSICAL sciences - Abstract
A distinction between two types of concepts, N-concepts and S-concepts, is presented. It is claimed that there is a fundamental difference between these two types of concepts and that S-concepts are used only in the social sciences, not in the natural sciences; hence there is a fundamental difference between social and natural science. Also, several different kinds of S-concepts - primary and derived, intra-cranial and extra-cranial, descriptions and evaluations, etc. - are discussed. [ABSTRACT FROM AUTHOR]

20. On the Use of Physical Models in Sociology.

Galtung, Johan

SOCIOLOGY literature ,SOCIAL science research ,SOCIAL scientists ,PHYSICAL sciences ,SOCIAL systems ,SOCIOLOGY - Abstract
The article discusses the use of physical models in sociology. The author feels that one of the reasons why physical terms are used by social scientists is because physics is best known among the sciences and this makes the reference to its elementary terms easily understandable. The author at the same time also feels that another reason for this may be that social scientists want to draw on the prestige of physics as the most advanced among all sciences. The author says that a social scientists, when asked to measure the terms used might resort to pressing the analogy too far by drawing on the properties of her physical model without having prepared his social system so as to be in some sense isomorphic to his physical system or he may introduce trivial or irrelevant categories or variables in his social system so as to fit more or less. The author feels that reasoning inside a physical model does not only require an abstract effort, it somehow makes use of our experiences with the physical world as well, thus making the use of physical models conducive to theoretical sociological work, but great care must be taken.

21. CAUSE AND EFFECT IN HUMAN GEOGRAPHY.

HUMAN geography ,SOCIAL policy ,EARTH sciences ,PHYSICAL sciences ,ENVIRONMENTAL sciences ,HISTORICAL geography ,GEOGRAPHY - Abstract
To sum up briefly: Firstly, the laws we invent are generalizations covering a vast number of data, not the laws of command which strict determinism suggests. If we find analogies in social laws it is because we must work on statistically derived means of behavior, rather than on the seemingly exclusive categories—like cause and effect—of the physical sciences. Secondly, the search for ultimate causes is as meaningless as the limiting of geography to examine one cause among many. Each circumstance must be set against the historical frame of reference wherein its origin lies, and it is in that context that the geographer will most nearly approach the solution of causes.
