In an algebra proposed by George Boole about 1850, the variables are permitted to have only two values true or false , usually written as 1 and 0, and the algebraic operations on the variables are limited to those defined as AND, OR, NOT.

George Boole 在1850年提出的代数学中，变量值只有两种：真和假，通常记为1和0，代数运算也仅局限于与、或、非。

The concept of a Bollean algebra was first proposed by the English mathematician George Boole in 1847.Since that time,Boole's original concept has been extensively developed and refined by algebraists and logicians.

布尔代数的概念最初是有英国数学家George Boole于1847年提出来的，从那时起，代数学家和逻辑学家们更广泛的发展了Boole的这一其实概念，并使之更加精练。

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。
