This book was released on 2023-06-02 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: At the close of the nineteenth century and the beginning of the twentieth, our knowledge of the activities in the interior of matter experienced a development which surpassed the boldest hopes that could have been entertained by the chemists and physicists of the nineteenth century. The smallest particles of chemistry, the atoms of the elements, which hitherto had been approached merely by inductive thought, now became tangible realities, so to speak, which could be counted and whose tracks could be photographed. A series of remarkable experimental investigations, stimulated largely by the English physicist, J. J. Thomson, had disclosed the existence of negatively charged particles, the so-called electrons, ¹/₂₀₀₀ the mass of the smallest atom of the known elements. A theory of electrons, based on Maxwell’s classical electrodynamical theory and developed mainly through the labours of Lorentz in Holland and Larmor in England, had brought the problem of atomic structure into close connection with the theory of radiation. The experiments of Rutherford proved, beyond a doubt, that atoms were composed simply of light, negative electric particles, and small heavy, positive electric particles. The new “quantum theory” of Planck was proving itself very powerful in overcoming grave difficulties in the theory of radiation. The time thus seemed ripe for a comprehensive investigation of the fundamental problem of physics — the constitution of matter, and an explanation in terms of simple general laws of the physical and chemical properties of the atoms of the elements. During the first ten years of the new century the problem was attacked with great zeal by many scientists, and many interesting atomic models were developed and studied. But most of these had more significance for chemistry than for physics, and it was not until 1913 that the work of the Danish physicist, Niels Bohr, paved the way for a really physical investigation of the problem in a remarkable series of papers on the spectrum and atomic structure of hydrogen. The ideas of Bohr, founded as they were on the quantum theory, were startling and revolutionary, but their immense success in explaining the facts of experience after a time won for them the wide recognition of the scientific world, and stimulated work by other investigators along similar lines. The past decade has witnessed an enormous development at the hands of scientists in all parts of the world of Bohr’s original conceptions; but through it all Bohr has remained the leading spirit, and the theory which, at the present time, gives the most comprehensive view of atomic structure may, therefore, most properly bear the name of Bohr. It is the object of this book to give the reader a glimpse of the fundamental conceptions of this theory, together with some of the most significant results it has attained. The book is designed to meet the needs of those who wish to keep abreast of modern developments in science, but have neither time nor inclination to delve into the highly mathematical abstract literature in which the developments are usually concealed. It is with this in mind that the first four chapters have been devoted to a general survey of those parts of physics and chemistry which have close connection with atomic theory. No attempt has been made at a mathematical development, and the physical meaning of such mathematical formulæ as do occur has been clearly emphasized in the text. It is hoped, however, that even those readers whose acquaintance with atomic theory is more than casual, will find the book a stimulus to further study of the Bohr theory. Here we wish to record our best thanks to Mr. and Mrs. Lindsay for the ability and the great care with which they have carried out the translation from the Danish original...FROM THE BOOK

Download or read book Niels Bohr written by Helge Kragh and published by Springer Nature. This book was released on 2022-06-15 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: Niels Bohr’s atomic theory of 1913 is one of the absolute highlights in the history of modern science. It was only with this work that physicists realized that quantum theory is an essential ingredient in atomic physics, and it was also only with this work that Rutherford’s nuclear model dating from 1911 was transformed into a proper theory of atomic structure. In a longer perspective, Bohr’s quantum atom of 1913 gave rise to the later Heisenberg-Schrödinger quantum mechanics and all its marvellous consequences. This book is a detailed account of the origin of the Bohr atom centred around his original scientific articles of 1913 which are here reproduced and provided with the necessary historical background. In addition to the so-called trilogy – the three papers published in Philosophical Magazine – also two other and less well-known yet important papers are included. The present work starts with a condensed biographical account of Bohr’s life and scientific career, from his birth in Copenhagen in 1885 to his death in the same city 77 years later. It then proceeds with a chapter outlining earlier ideas of atomic structure and tracing Bohr’s route from his doctoral dissertation in 1911 over his stays in Cambridge and Manchester to the submission in April 1913 of the first part of the trilogy. The reproduction of Bohr’s five articles is followed by notes and comments directly related to the texts, with the aim of clarifying some of the textual passages and to explicate names and subjects that may not be clear or well known. The reception of Bohr’s radically new theory by contemporary physicists and chemists is discussed in a final chapter, which deals with the immediate reactions to Bohr's theory 1913-1915 mostly among British, German and American scientists. Historians of science have long been occupied with Bohr’s atomic theory, which was the subject of careful studies in connection with its centenary in 2013. The present work offers an extensive source-based account of the original theory aimed at a non-specialist audience with an interest in the history of physics and the origin of the quantum world. In 1922 Bohr was awarded the Nobel Prize for his theory. The coming centenary will undoubtedly cause an increased interest in how he arrived at his revolutionary picture of the constitution of atoms and molecules.
Download or read book Universal Aspects of Scientific Practice Commitment Methodology and Technique written by Giora Hon and published by Springer Nature. This book was released on 2023-12-06 with total page 111 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a unique contribution to philosophy of science from the perspective of the practice of science. It focuses on processes that generate scientific knowledge and seeks general and universal features that characterize scientific practice; features that are inherent to the practice of science. Science is an activity, and the scientist is an agent who pursues some practice, which in one way or another engages evidence. In science, claims to knowledge are typically supported by argument that engages evidence at some point in explanation, in prediction, or indeed in any mode of presenting data and its interpretation. Thus, the practice of science includes at least three elements so that an argument can be formulated: presuppositions, modes of inference, and consequences that relate to evidence. The authors discuss in detail eight cases in chronological order with which they illustrate how commitment, methodology, and technique come into play in the practice of an individual physicist or a group of researchers in the physical sciences. Each case highlights aspects of the roles these categories play in scientific practice, where the goal is to generate and extend scientific knowledge.

Download or read book From Data to Quanta written by Slobodan Perovic and published by University of Chicago Press. This book was released on 2021-10-01 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first comprehensive philosophical and historical account of the experimental foundations of Niels Bohr’s practice of physics. Niels Bohr was a central figure in quantum physics, well known for his work on atomic structure and his contributions to the Copenhagen interpretation of quantum mechanics. In this book, philosopher of science Slobodan Perovic explores the way Bohr practiced and understood physics, and analyzes its implications for our understanding of modern science. Perovic develops a novel approach to Bohr’s understanding of physics and his method of inquiry, presenting an exploratory symbiosis of historical and philosophical analysis that uncovers the key aspects of Bohr’s philosophical vision of physics within a given historical context. To better understand the methods that produced Bohr’s breakthrough results in quantum phenomena, Perovic clarifies the nature of Bohr’s engagement with the experimental side of physics and lays out the basic distinctions and concepts that characterize his approach. Rich and insightful, Perovic’s take on the early history of quantum mechanics and its methodological ramifications sheds vital new light on one of the key figures of modern physics.
Download or read book From Photons To Atoms The Electromagnetic Nature Of Matter written by Funaro Daniele and published by World Scientific. This book was released on 2019-09-10 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Motivated by a revision of the classical equations of electromagnetism that allow for the inclusion of solitary waves in the solution space, the material collected in this book examines the consequences of adopting the modified model in the description of atomic structures. The possibility of handling 'photons' in a deterministic way indeed gives a chance to review the foundations of quantum physics. Atoms and molecules are described as aggregations of nuclei and electrons joined through organized photon layers resonating at various frequencies, explaining how matter can absorb or emit light quanta. Some established viewpoints are subverted, offering an alternative scenario. The analysis seeks to provide an answer to many technical problems in physical chemistry and, at the same time, to raise epistemological questions.
