 “奇/偶数” -- 将童心进行到底


大家都知道英语中奇数叫“odd number”,偶数叫“even number”。那你有没有疑惑过,为什么这么叫呢?呵呵,明天“六一”,我们将童心进行到底,探寻“even/odd”为什么叫“奇/偶数”。
Even从古日耳曼语中来,它出现在古英语中时的意思是“水平的、不倾斜的”。偶数被2除之后,得到的两个数是相等的。如果把它们放到天平上,那么天平是水平的、没有倾斜的。所以啦,偶数就是even。 Odd从古斯堪的纳维亚语中来,经过一系列演变,有了“多余的”意思。奇数被2除余1,既然有多余了,那么奇数就是odd。 有没有觉得如此推理的逻辑很奇怪呢?语言就是这么奇怪、这么有意思喽! 看下面例句:
Graphs are on even pages and tables are on odd pages.
图在偶数页,表格在奇数页。
