…After that, he served as professor of physics at both the universities of London and Cambridge, and served in the important position of Secretary of State for Science and Industry from 1939 to 1949. In 1924, he demonstrated the existence of the ionosphere, predicted by A.E. Kennelly and O. Heaviside, by measuring reflected radio waves, and two years later, he discovered the existence of a new ionosphere (named the Appleton layer) above it. Thus, he paved the way for research into the ionosphere using radio waves, and made notable achievements in the study of radio wave propagation, the ionosphere, and other physics. … *Some of the terms mentioned in the "Appleton Formation" are listed below.

…その後,ロンドン,ケンブリッジ両大学の物理学教授を経て,39年から49年まで科学産業庁長官の要職にあった。 1924年,A.E.ケネリーとO.ヘビサイドによって予言されていた電離層の存在を電波の反射波の測定により実証し,2年後には,その上部に新しい電離層(アップルトン層と名付けられた)が存在することを発見した。こうして,電波による電離層の研究に道を開くとともに,電波伝播(でんぱ),電離層などの物理学的研究に顕著な業績を残した。… ※「アップルトン層」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
