• How to mathematically distinguish "red" from "green"? - boxer (52 bytes) 2005-3-04, 12:23:34
  • Fagus happens to be right in this case - Pepe_Le_Pue (65 bytes) 2005-3-04, 13:15:46
    • A limited space can also be represented by 3xa - boxer (283 bytes) 2005-3-04, 13:25:58
      • In the continuous and infinite case - Pepe_Le_Pue (54 bytes) 2005-3-04, 13:55:08
      • 那得看这里的颜色怎么定义的了 - 是人眼能看到的，还是光的波长 - Smashedmouth (0 bytes) 2005-3-04, 13:45:38
        • 还种方式说：所有人眼能感受到的percetion, 是不是每种都可以用一种单色光来产生 - Smashedmouth (44 bytes) 2005-3-04, 13:56:07
    • 这坛子上都是些什么人啊? 一点基本概念都没有. - Hah (22 bytes) 2005-3-04, 13:24:02
      • 一维还是三维，跟可数不可数关系不大。 可以抬杠说，人眼的分辨率不是无限的，所以 - Smashedmouth (14 bytes) 2005-3-04, 14:02:54
        • 按照你的意思, 盲人是不会数数的. - Hah (57 bytes) 2005-3-04, 14:53:39
          • 人眼看得见看不见，关系到颜色的定义。对先天盲人来说，颜色只有一种。 - Smashedmouth (66 bytes) 2005-3-04, 14:59:03
            • According to your proof of Fagus's argument - boxer (302 bytes) 2005-3-04, 15:16:01
              • I am not trying to prove/support anything. I am merely saying - Smashedmouth (330 bytes) 2005-3-04, 15:29:13
                • Without considering intensity or brightness - boxer (135 bytes) 2005-3-04, 16:28:10
                  • 这就得了。这儿也有是否“以人为本“的问题咧。 - Smashedmouth (0 bytes) 2005-3-04, 16:36:22
