Die Luftdektrizität Methoden und Resultate der neueren Forschung

Abstract

OF late years there has been great activity in this country in investigating electrical phenomena in gases and in advancing and discussing theories as to the nature and properties of ions. But this work has been mainly done in the laboratory or by mathematicians. In central Europe, thanks largely to the influence of Exner and of Elster and Geitel, there have been many workers studying the electrical phenomena presented by nature. Amongst them Prof. Gockel takes a distinguished place. In the present volume he gives an exceedingly up-to-date account of our knowledge of atmospheric electricity. The amount that has recently been written on the subject will impress itself on anyone who refers to the Physikalische Zeitschrift or the publications of the Vienna Academy. The references in the present volume are evidence of Prof. Gockel's familiarity, not merely with recent work in German, but also with that in English, whether done here or in America. He makes, for instance, numerous references to Simpson's observations in Lapland. Die. Luftdektrizitat. Methoden und Resultate der neueren Forschung. By Prof. Albert Gockel. Pp. vi+206. (Leipzig: S. Hirzel, 1908.) Price 6 marks.
