Synopsis

Explore the foundations of atomic theory and how quantum ideas reshape our view of matter. This edition presents Bohr's landmark essays as a lucid, freer discussion of complex ideas.

These essays trace the shift from classical electrodynamics to quantum concepts in atomic structure. They discuss how hydrogen's spectrum helped forge the quantum picture, and how Bohr connects spectral lines to the behavior of electrons in atomic orbits. The work also surveys how the quantum theory explains periodic properties and the emergence of the periodic table, while addressing the challenges and progress in understanding X-ray spectra.

• How the hydrogen spectrum drove new ideas about stationary states and energy levels.


• The link between spectral lines, Planck's constant, and atomic structure.


• The development of the quantum theory of spectra and its implications for the periodic table.


• Historical context and Bohr’s perspective on the evolving view of atoms and electrons.

Ideal for readers of the history of physics, as well as anyone curious about how quantum theory began to explain the behavior of matter at the smallest scales.

A propos du livre

Présentation de l'éditeur

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.
