Mr Derbyshire, whose bookhas just been published in Britain after appearing in America last year, givesan intriguing account of these developments, and of the mathematiciansinvolved, such as George Boole, who "married algebra to logic" by inventingalgebraic ways to express logical arguments: he led an almost saintly life, butdied after his wife treated him for a chill by dousing him in buckets of icywater.

德比夏尔的这本书去年在美国出版，紧接着现在又在英国上市。书中对代数学的发展和历史上的数学家做了生动有趣的描述。例如乔治·布尔，他把&代数嫁给了逻辑&，用代数的方式表达逻辑参数。乔治·布尔一生圣洁，但是却死于他妻子淋头而下的冰水所致的风寒。

Although translator has turned from being a crystal ball by which the original culture can unrestrainedly penetrate to another crystal ball by which the target culture can freely traverse, the translator's personal embodiment, in the process of cognitive act, are still absent in translation studies. Translators are still subjects without body or simply disembodied subjects.
