查询词典 Sagan

Carl Sagan has entertainingly described this phenomenon, musing about the destiny of bacteria that reproduce by dividing into two every 15 minutes. Says Sagan:"That means four doublings an hour, and 96 doublings a day. Although a bacterium weighs only about a trillionth of a gram, its descendants, after a day of wild asexual abandon, will collectively weigh as much as a mountain...in two days, more than thesun - and before very long, everything in the universe will be made of bacteria." Not to worry, says Sagan: Some obstacle always impedes this kind of exponential growth. The bugs run out of food, or they poison each other, or they are shy about reproducing in public.

Carl Sagan 曾经开玩笑地解释这种现象，假设有一种细菌每15分钟可以分裂一次，亦即代表每一小时复制四次，一天可复制96次，虽然单一个细菌其重量只有一兆分之一公克重，但是只要经过一天无止尽的无性生殖，其重量可能会比一座山还重，经过两天后，甚至会比太阳还重，要不了多久所有的宇宙都将由这种细菌所组成，不过 Sagan 又说，大家不必担心，上天一定会安排障碍来阻止其倍数成长，有可能他会耗尽食物，或是毒死自己，或是有可能羞于在大庭广众之下复制。
