“ 那种数学比例是多么显而易见

又是多么必然

那是一个平方数列：1:4:9 ！

而曾以为这个序列止步于此、止步于三维空间，

是多么天真 啊！”

——2001：太空漫游，阿瑟·克拉克

“How obvious—how necessary—was that mathematical ratio of its sides, the quadratic sequence 1:4:9!

And how naïve to have imagined that the series ended there, in only three dimensions!”

— Arthur C. Clarke, 2001: A Space Odyssey
