In the same year he became chairman of the Astronomy Department at Northwestern University, and was responsible for planning the University's new computer center. In 1958 Strand accepted a position as head of the Astrometry and Astrophysics Division at the U.S. Naval Observatory rising to the position of Scientific Director in 1963. He pioneered in the determination of stellar distances using reflecting telescopes, and was primarily responsible for the design and construction of the Strand Astrometric Telescope, dedicated in 1964 at the United States Naval Observatory Flagstaff Station in Arizona.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Kaj Aage Gunnar Strand」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
