<注釋>One might well ask how many European scientists it takes to turn on a light bulb.If we think in terms of the names used for various units in the International, or meter-kilogram-second, System,a fair number are involved.Alphabetically arranged, these units are theampere, named for the French scientist Andrô Marie Ampère (775-83'); thecoulomb, after the French scientist Charles A. de Coulomb (73'-80'); thefarad and the faraday, after the British scientist Michael Faraday (79-8'7); thejoule, after the British scientist James P. Joule (88-889); thenewton, after the British scientist Sir Isaac Newton ('42-727); theohm, after the German scientist Georg S. Ohm (789-854); thevolt, after the Italian scientist Count Alessandro Volta (745-827); and thewatt, after the British scientist James Watt (73'-89). Definitions such as that ofohm, .a unit of electrical resistance equal to that of a conductor in which a current of one ampere is produced by a potential of one volt across its terminals,. take on more human connotations when we think of how human contributions to the study of electricity are memorialized in them.The dates of first recorded use of the terms in English are as follows:ampere, 88; coulomb, 88; farad, 8'; faraday, 904; joule, 882; newton, 904; ohm, 870 (suggested in 8'); volt, 873; and watt, 882.
有人可能會問經(jīng)過了多少位歐洲科學家才點亮了燈泡。如果我們以國際單位制或米—千克—秒單位制中各種單位之名稱的形式來考慮的話,相當數(shù)量的人被包括了。這些單位按字母順序排列是安培, 以法國科學家安德烈·馬里耶·安培(775—83'年)命名; 庫侖, 以法國科學家夏爾·?!さ聨靵?73'-80'年)命名; 法拉法拉第, 以英國科學家邁克爾·法拉第(79—8'7年)命名; 焦耳 以英國科學家詹姆斯·皮·焦耳(88—889年)命名; 牛頓, 以英國科學家伊薩克·牛頓爵士('42—727年)命名; 歐姆, 以德國科學家格奧爾格·斯·歐姆(789—854年)命名; 伏特, 以意大利科學家亞歷山德羅·沃爾塔伯爵(745—827年)命名; 瓦特, 以英國科學家詹姆士·瓦特(73'—89年)命名。 定義諸如歐姆, .電阻單位,等于一伏特電壓加于導體兩端在導體內(nèi)部產(chǎn)生一安培電流之導體電阻., 當我們想到人們對電學做出的貢獻是怎樣在這之中得到紀念的時候,就帶上了更多的人文內(nèi)涵。英語中首次有記錄的使用這些說法的時間如下:安培, 88; 庫侖, 88; 法拉, 8'; 法拉第, 904; 焦耳, 882; 牛頓, 904; 歐姆, 870(在8'年建議使用); 伏特, 873;和 瓦特, 882
