TL;DR: In this paper, the Tamm-Dancoff method is applied to the calculation of the electrostatic properties of the deuteron, and the state vector is assumed to contain amplitudes for at most two mesons in the field.
Abstract: The Tamm-Dancoff method is applied to the calculation of the electrostatic properties of the deuteron. The state vector is assumed to contain amplitudes for at most two mesons in the field, but the possible presence of nucleon-antinucleon pairs is ignored. A formula applicable to the calculation of any multipole moment is derived and used to compute the leading exchange corrections, of order ${g}^{2}$ and ${g}^{4}$, respectively, to the usual expression for the quadrupole moment. For a suitably chosen hard-core wave function the ratio of successive terms is about one tenth, and the ${g}^{2}$ term is itself only a few percent of the total effect.

TL;DR: The phenomenological theory of the deuteron charge distribution is discussed in this paper, where finite nucleon sizes and elastic electron-deuteron scattering are given a consistent phenomenological treatment under the simplest assumptions.
Abstract: The phenomenological theory of the deuteron charge distribution is discussed. Finite nucleon sizes are included. The theory is applied to the deuteron quadrupole moment, the low-energy photonuclear reaction $\ensuremath{\gamma}+d\ensuremath{\rightarrow}n+p$, and elastic electron-deuteron scattering. It is shown that these phenomena can be given a consistent phenomenological treatment under the simplest assumptions.

TL;DR: In the mine of recent American philosophy runs a rich and unique vein of many ores as mentioned in this paper, and White in Social Thought in America* has searched these and has found among them a congruence which he has called "the revolt against formalism." He has shown that those who work this vein with most vigour were and are, by and large, a small band of great and robust amateurs in philosophy including Thorstein Veblen, Oliver Wendell Holmes, Charles Beard and James Harvey Robinson.
Abstract: In the mine of recent American philosophy runs a rich and unique vein of many ores. Professor M. G. White in this book Social Thought in America* has searched these and has found among them a congru ence which he has called "the revolt against formalism." He has shown that those who work this vein with most vigour were and are, by and large, a small band of great and robust amateurs in philosophy includ ing Thorstein Veblen, Oliver Wendell Holmes, Charles Beard and James Harvey Robinson. Despite obvious divergences of interest and profession these men are held together by a common temper which perhaps can best be labelled "pragmatism/' That is, each in his partic ular discipline has been concerned with razing the mildewed block structures of the past, and putting in their stead a new architecture moulded to the stern requirements of practical life. Though Profes sor White has not chosen to do so, I think we may add to the above group of names that of Percy Williams Bridgman, and I shall be con cerned, explicitly and implicitly, in this essay with articulating this hypothesis. It has become rather a common place that the Newtonian world picture dominated the structure of science and philosophy from the 17th Century until Maxwell and Einstein. The mechanistic and deter ministic consequences of Newtonian mechanics have long been re cognized and much discussed, but there is another corrolary which is noticed more rarely, a corrolary which can perhaps be called "New tonian formalism". Specifically what I mean is this. Among the three classic laws of motion of Newton is the famous law of inertia which states that a body at rest shall remain at rest while a body in motion shall, if no force acts, remain in uniform motion, in a straight line, to the infinite. This apparently harmless and intuitive law had for an * Footnotes are to be found at the end of the essay.

TL;DR: Foundations of Science as discussed by the authors is a journal devoted to methodological and philosophical topics concerning the structure and the growth of science, and it serves as a forum for exchange of views and ideas among working scientists and theorists.
Abstract: Foundations of Science focuses on significant methodological and philosophical topics concerning the structure and the growth of science. It serves as a forum for exchange of views and ideas among working scientists and theorists of science, and promotes interdisciplinary cooperation. The journal presents foundational issues of science in a way that is free from unnecessary technicalities, yet faithful to the scientific content. Its aim is not simply to identify and highlight foundational issues and problems, but to suggest constructive solutions. While acknowledging that various sciences have their own approaches and methods, the editors hold that important truths can be discovered about and by the sciences and that these transcend cultural and political contexts. The editors believe that the central foundational questions of contemporary science can be posed and answered without recourse to sociological or historical methods. Manuscripts should be submitted as an attached file to an e-mail directed to the Editor-inChief, Diederik Aerts at the address: FOSFoundationsOfScience@gmail.com with a cc to the address: diraerts@vub.ac.be The file should be an electronic copy of the original, not blinded, and a pdf version of the article, also not blinded. Authors have to additionally give the names and e-mail addresses of five potential reviewers, who need to be scientists considered to have expertise in the domain where the subject of the manuscript is situated.

TL;DR: In recent years, there have been great advances in understanding the interaction of two nucleons, both phenomenologically and in terms of a fundamental meson-nucleon coupling as discussed by the authors.
Abstract: In recent years there have been great advances in understanding the interaction of two nucleons, both phenomenologically and in terms of a fundamental meson-nucleon coupling. The present report describes the methods and achievements of phenomenology and meson field theory in this subject.

TL;DR: The role of meson exchange currents in electromagnetic (and weak) interactions of nuclei has been repeatedly inquired into as mentioned in this paper, which is the aim of the work being reported, which also consists in a systematic study of form factors of levels in 12C at excitation energy above 14 MeV.
