八元数的八维并不仅仅有趣在数字8上，实际上，Baez强调了8只是起最喜爱的三个数字中的一个(其他的两个是5和24)。

The eight dimensions of the octonions aren't the only interesting thing about the number eight, however. Baez highlights the number eight as one of his three favorite Numbers.

The so called binary system, 1 these zeros and ones that you'd probably have some vague sense underlie all computers today actually reduced to the exact same grade school kind of math and system except with computers, 1 because it's a lot easier to use just two digits, zero and one.

所谓的二进制就是，你觉得模糊的0与,在电脑上计算,事实上可以简化为跟小学数学一样,只是在电脑上计算而已，因为它更容易，仅仅使用两个数字，0与。
