...The history of telecommunications has already spanned more than a century and a half, and continues to develop without rest until today as we move towards the realization of an advanced information society. GS Ohm discovered Ohm's law in 1826, and M. Faraday discovered the phenomenon of electromagnetic induction in 1831. Based on these discoveries, JC Maxwell perfected the theory of the electromagnetic field in 1864 and theoretically demonstrated the existence of electromagnetic waves, and in 1888 HR Hertz experimentally demonstrated the existence of electromagnetic waves by using electric sparks. The history of telecommunications began at a time when the foundations of electromagnetism were being established. ... *Some of the terminology that mentions "Hartley, R. von L." is listed below.

…電気通信の歴史はすでに1世紀半以上にも及んでおり,現在も高度情報社会の実現に向けてとどまるところなく発展を続けている。G.S.オームがオームの法則を発見したのは1826年,M.ファラデーが電磁誘導現象を発見したのは31年である。これらをもとにして64年J.C.マクスウェルは電磁場理論を大成し,電磁波の存在を理論的に示し,88年にはH.R.ヘルツが電気火花により電磁波の存在を実験的に実証した。電気通信の歴史はこのような電気磁気学の基礎が築かれつつある時代にすでに開始されている。… ※「Hartley,R.von L.」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 |
