...Furthermore, the discovery of radium (Curie and Marc Curie, 1898) completely shook up the conservation of energy as well as mechanics and thermodynamics. Even after it was revealed that radioactivity is caused by atomic decay (Rutherford and Soddy, 1902), Egon Ritter von Schweidler (1873-1945) deduced from the fluctuations in the number of decays per unit time (1905) that this was entirely governed by chance. This represented the collapse of the causal laws and determinism that form the basis of classical physics. ... *Some of the terminology references "Schweidler, ERvon" are listed below.

…さらにラジウムの発見(キュリー夫妻,1898)はエネルギーの保存をはじめとして力学,熱力学を根底からゆるがした。放射能が原子の崩壊によることが明らかになった(ラザフォードとソディ,1902)後にも,シュワイドラーEgon Ritter von Schweidler(1873‐1945)は単位時間当りの崩壊数に見られるゆらぎからこれがまったく偶然に支配されていることを読みとった(1905)。これは古典物理学の土台をなす因果律,決定論の破綻(はたん)を意味する。… ※「Schweidler,E.R.von」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 |
