Excerpt from The Theory of Spectra and Atomic Constitution: Three Essays
The three essays which here appear in English all deal with the application of the quantum theory to problems of atomic structure, and refer to the different stages in the development of this theory.
The first essay "On the spectrum of hydrogen" is a translation of a Danish address given before the Physical Society of Copenhagen on the 20th of December 1913, and printed in Fysisk Tidsskrift, XII. p. 97, 1914. Although this address was delivered at a time when the formal development of the quantum theory was only at its beginning, the reader will find the general trend of thought very similar to that expressed in the later addresses, which form the other two essays. As emphasized at several points the theory does not attempt an "explanation" in the usual sense of this word, but only the establishment of a connection between facts which in the present state of science are unexplained, that is to say the usual physical conceptions do not offer sufficient basis for a detailed description.
The second essay "On the series spectra of the elements" is a translation of a German address given before the Physical Society of Berlin on the 27th of April 1920, and printed in Zeitschrift für Physik, VI. p. 423, 1920. This address falls into two main parts. The considerations in the first part are closely related to the contents of the first essay; especially no use is made of the new formal conceptions established through the later development of the quantum theory. The second part contains a survey of the results reached by this development. An attempt is made to elucidate the problems by means of a general principle which postulates a formal correspondence between the fundamentally different conceptions of the classical electrodynamics and those of the quantum theory.

Niels Bohr (1885–1962) was a Danish physicist who played a key role in the development of atomic theory and quantum mechanics, he was awarded the Nobel Prize for Physics in 1922. This 1924 second edition contains three essays dealing with the application of quantum theory to problems of atomic structure.

Paperback. Condition: New. Print on Demand. This book offers a fascinating exploration of atomic structure and its connection to the spectra of light emitted by elements. The author takes the reader on a journey through the history of scientific discoveries, beginning with empirical laws governing the spectral lines of hydrogen, and moving on to the groundbreaking work of Planck and Rutherford on black body radiation and the nuclear model of the atom. The book delves into the challenges posed by classical physics in explaining these phenomena and presents a compelling argument for a new, quantum mechanical approach to understanding atomic behavior. The author's use of the quantum theory provides a framework for explaining the spectral lines of hydrogen and other elements, revealing a hidden correspondence between the structure of atoms and the properties of light they emit. This book offers a captivating glimpse into the revolutionary shift in scientific thought that occurred in the early 20th century, as physicists sought to unravel the mysteries of the atomic realm.
