Excerpt from The Popular Science Monthly, Vol. 61: November, 1901, to April, 1902
In the same way we may have atoms which carry three, four, five or six electrons. Thus we may interpret the facts of chemical valency and Faraday's Law of Electrolysis in terms of the electron.
We are thus confronted by the idea, long ago suggested by Weber and by Helmholtz, that the agency we call electricity is atomic in structure, that is to say, we can only have it in amounts which are all exact multiples of a certain small unit. Electricity therefore re sembles those articles of commerce like cigars, which we can buy in exact numbers, 1, 10, 50, 100, 1000, but we cannot buy half a cigar or five sixths of a cigar. If then the law which holds good for electricity in association with atoms during electrolysis holds good generally, a very important advance has been made in establishing the fact that there is a small indivisible unit of it which can be multiplied but not divided, and every quantity of electricity, small or large, is an exact integer multiple of this unit, the electron.

Paperback. Zustand: New. Print on Demand. This book delves into the evolution of the contact process for sulfuric acid manufacture, a critical industrial process with deep historical roots. The author traces the journey from Phillips' initial discovery of platinum's catalytic role in 1831 to the present day, highlighting the contributions of Woehler, Mahla, and Winckler along the way. The text explores the mechanisms behind the catalytic reactions involved, showcasing the profound impact of high temperatures on the process. Ultimately, the book underscores the significance of this process in the production of sulfuric acid, a cornerstone of inorganic technology and a vital component in the synthesis of organic dyes and other essential compounds.
