With staff member Sanders he reduced data taken by the latter near the equator to show the feasibility. This all led to the first Kenya Expedition which started in 1931.

Growing Up in Oegstgeest, close to Leiden a few years later. Oort grew up there, attended elementary and secondary school in Leiden. He had a strong interest in exact sciences and went to Groningen to study physics or astronomy, to a large extent attracted by the fame of astronomer J.C. Kapteyn.作者: 補(bǔ)助 時(shí)間: 2025-3-27 12:34

In 1924 he made an extensive tour of the USA, spending some time in Pasadena, California and Mount Wilson Observatory before returning to the Netherlands to start his appointment in Leiden.作者: 下邊深陷 時(shí)間: 2025-3-27 17:02 作者: sleep-spindles 時(shí)間: 2025-3-27 21:26 作者: gimmick 時(shí)間: 2025-3-28 00:02

Rotation of the Galaxy; Marriage,ch resulted in a thesis defended in Groningen in 1926. Oort met his future wife and married her in 1927. A study by Bertil Lindblad sparked the idea of differential Galactic rotation, for which he determined the observational consequences and which he subsequently showed existed in available data.作者: 玉米 時(shí)間: 2025-3-29 17:05
Professor and Adjunct-Director,un. Oort became General Secretary of the IAU in 1935.

Galactic Structure and the Dwingeloo Telescope, density wave, showed evidence for activity in the nucleus of the Galaxy, and led to the discovery’s of high-velocity clouds. Oort proposed that these showed an inflow of matter into the Galaxy from intergalactic space and provided insights into the problem of galaxy formation.作者: Optic-Disk 時(shí)間: 2025-3-30 05:19 作者: 常到 時(shí)間: 2025-3-30 11:42
