Title: Collected Scientific Papers of John Aitken Edited . With Introductory Memoir, by Cargill G. Knott
Description: Cambridge University Press, 1923. Hardcover. John Aitken, FRS, FRSE (1839-1919) was a Scottish meteorologist, physicist and marine engineer. He was one of the founders of cloud physics and aerosol science, who built the first apparatus to measure the number of dust and fog particles in the atmosphere, a koniscope. Aitken was the author of a number of important pioneering discoveries On Dust, Fogs and Clouds (the title of an 1880 article he penned). As early as 1874, Aitken had concluded that when water vapour in the atmosphere condenses, it must condense on some solid particle, and thus, without the presence of dust and other aerosol particles in the air, there would be no formation of fog, clouds, or rain. In 1884, he concluded that the brilliant colours often seen in the sunset are due to the refraction of light by dust particles in the upper atmosphere.Today, his name is given by atmospheric scientists to the smallest atmospheric aerosol particles (Aitken nuclei), those with a radius less than 0.1 micrometres. This size range include the newly nucleated particles whose existence Aitken demonstrated. (Wiki). He used the area about Kingairloch, Lochaber as a standard for clean air.591p portrait frontis with folding diagrams and charts.
