Tides, Statistics and the Art of Discovery,n great detail. The letters also contained comments on World War I. Kapteyn, being prevented from visiting Mount Wilson, had to be kept from resigning his position as Research Associate in California. Hale told him that he could do the work that came with this appointment anywhere he liked.constitutional 发表于 2025-3-23 14:49:32
First Attempt,lished a ‘first attempt’ to understand the distribution of stars and their motions in a consistent picture: the Kapteyn Universe. His model turned out to be largely correct in the vertical direction. Here the Sun is now away from the center, allowing the Star Streams to be interpreted as a supporting rotational motion of the System.Inkling 发表于 2025-3-23 21:20:44
Cape Photographic Durchmusterung,star catalogues and maps of the whole sky. He found himself unable to persuade the leaders of the project to accept his method of parallactic measurement. The Carte du Ciel provided serious problems with regard to the funding of Gill’s work on the CPD, owing to obstruction by Astronomer Royal William Christie.Monocle 发表于 2025-3-24 00:57:37

Colors and Motions,t regions of the sky. At that time Kapteyn started to look at patterns of stellar proper motions on the sky, which could be used to estimate distances of stars statistically. In Groningen he was very active in the Physical Sciences Society, which promoted the understanding of scientific progress among a wide audience.报复 发表于 2025-3-24 12:28:09

Kapteyn (1851-1922) was a Dutch astronomer who contributed heavily to major catalogs of star positions, such as the Cape Photographic Durchmusterung and the Harvard-Groningen Durchmusterung, and arranged extensive international cminion 发表于 2025-3-24 18:40:02
