His most famous creation was the Ward–Takahashi identity, originally known as "Ward Identity" (or "Ward Identities"). This celebrated result, in quantum electrodynamics, was inspired by a conjecture of Dyson〔F. J. Dyson, The S matrix in quantum electrodynamics, ''Phys. Rev.'' 75, 1736–1755 (1949).〕 and was disclosed in a one-half-page letter typical of Ward's succinct style. In their recent book entitled ''Quantum Electrodynamics'', Greiner and Reinhardt state in their discussion of charge renormalisation: "Yet the Ward Identity has a much more fundamental significance: ''it ensures the universality of the electromagnetic interaction''."〔W. Greiner and J, Reinhardt, ''Quantum Electrodynamics'', 4th Ed. (Springer, Berlin, 2009).〕 In his book ''The Infinity Puzzle'', Frank Close devotes a whole chapter to this Ward creation and entitles it The Identity of John Ward, in which he writes: "Ward Identities lie at the very foundations of renormalization."〔F. Close, ''The Infinity Puzzle'' (Oxford University, Oxford, 2011).〕 Andrei Sakharov classified Ward as one of the "''titans''" of quantum electrodynamics alongside Dyson, Feynman, Schwinger, and Tomonaga.〔A. Sakharov, ''Memoirs'' (Knopf, New York, 1990).〕 In this regard, it has been said that physicists have made use of his principles and developments "''often without knowing it, and generally without quoting him.''"〔M. Dunhill, Professor John Clive Ward, in ''The Merton Record'' (Oxford University, Oxford, 1995).〕 ==Additional contributions== 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「John Clive Ward」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.
