If my poor Flatland friend retained the vigour of mind which he enjoyed when he began to compose these Memoirs, I should not now need to represent him in this preface, in which he desires, firstly, to return his thanks to his readers and critics in Spaceland, whose appreciation has, with unexpected celerity, required a second edition of his work; secondly, to apologize forcertain errors and misprints (for which, however, he is not entirely responsible); and, thirdly, to explain one or two misconceptions. But he is not the Square he once was. Years of imprisonment, and the still heavier burden of general incredulity and mockery, have combined with the natural decay of old age to erase from his mind many of the thoughts and notions, and much also of the terminology, which he acquired during his short stay in Spaceland. He has, therefore, requested me to reply in his behalf to two special objections, one of an intellectual, the other of a moral nature.

评分很有滋味的小说,描述细致笔触幽默。 作者对二维世界不仅有出自逻辑与数学角度的构想(比如平面国的人如何认知这个世界,如何判断男女以及不同个体,如何通过明暗变化与线条长短的配合来判断来者边数等),更延伸到了意识形态、思想文化以及宗教信仰等层面(比如边数决定等级,...
评分一个科学寓言:有个射击运动员在例行训练,在标靶上生活的一种生物中的科学家观察到他们的世界每隔一定时间段,就会出现一个洞。他宣布了这个物理定律。整个上午,射击运动员都在射击,对于标靶生物来说,这是很长的历史时期,他们认为他们的科学家是正确的。遗憾的是下午射击...
评分《生活大爆炸》里,谢耳朵有一次说:Sometimes when I feel stifled and want a change of scenery, I use my imagination. One of my favorite places to visit is the two dimensional world described in Edwin Abbott's mathematical fantasy, "Flatland." 这本一百多年以...
