那只是你的“感觉”
从理性的分析，其实过程是这样的：
女人总有自己好多的metric
要找什么样的什么样的什么样的，A/B/C/D/E
有一天她发现她找到了让她兴奋的，具备A/B/C/D特质的
其实一般都是被某一点所吸引，然后夸张了对方的优点，忽视了自己的其它metric
然后，然后，中招了吧，吃亏了吧，伤心了吧，，，，，
再然后，就开始理性了吧，土象虽然没情趣但是也还是稳定的吧
但是这样的又能长久？
感情这个东西还是那一瞬间的冲动和触电般的感性决定了其持久性
如果单纯的理性的寻找“合适的”，满足当前安全感的
未必就是一个长久的好的选择
选择等于放弃，放弃也是一种选择
你今天觉得这个很好，在未来你的安全感得到了满足，你又会缺乏其它方面的安全感
人，天性就是贪婪，不满，欲求不足 |

within your metrics is less than 40%.
You can calculate the cumulative probability of a normal distribution, which
will show:
1) P(mean +/- 0.5*sigma) = 38.3%
2) P(mean +/- 1*sigma) = 68%
3) P(mean +/- 3*sigma) = 99%
So, I strongly suggest you to widen your metrics to 3 times of standard

vector就是一个一维数组v
2.
dual vector的意思是，对v做加权平均时候的权值组成的数组w
one form的意思是这个加权平均函数

或者说是对m个one form，n个vector再做一次加权平均。最后得到一个数字。

发帖数: 40 | 49 我正在自学一点real analysis，看到metric spaces时就觉得概念很难理解习题也难。请
教下面的两道题如何做？谢了。
1) Give an example of a complete metric space that is bounded but not copmact.
2) Let a, b belong to R, and a < b, prove that [a, b] is compact.
顺便请问compactness这个概念该如何理解? 能否介绍一本简明易懂的拓扑学课本?
谢谢!! |

you can show on a metric space the metric function is continuous. |
