Radioactivity and the Latest Development of the Theory of Chemical Elements
Full Text
K. Fajans. Radioaktivität und die neuste Entwickelung der Lehre von den chemischen Elementen (Sammlung Vieweg, Heft 45). Braunschweig—1919.
Fajans’s booklet is of enormous interest both for physicists and chemists and for biologists and physicians, giving a clear and precise account of the complex field of radioactive transformations. Especially interesting are those chapters of the doctrine of radioactivity in which the connection between radioactive transformations and the periodic system is discussed, and where we find all the latest investigations in this field set side by side.
If we add to this that, in the appendix, the author gives a description of Rutherford’s remarkable experiments on the disintegration of nitrogen, then we must acknowledge that Fajans’s book gives a very up-to-date picture of the structure of matter in connection with radioactivity, and that this book may be confidently recommended to anyone wishing to become seriously acquainted with these branches of science. Fajans’s book has been translated into Russian and will be published by the publishing department of the NKS.
