从艾宾浩斯遗忘曲线中可以看出我们如潮水般汹涌的遗忘，从中观察时间间隔20分钟，1小时，8-9小时一天，两天，31天我们不复习会记的所学的百分之多少，对此先给一个复习的方法
复习点的确定
人的记忆分短期记忆和长期记忆两种
第一个记忆周期是5分钟
第二个记忆周期是30分钟
第三个记忆周期是12小时
这三个记忆周期属于短期记忆的范畴。
下面是几个比较重要的周期
第四个记忆周期是1天
第五个记忆周期是2天
第六个记忆周期是4天
第七个记忆周期是7天
第八个记忆周期是15天
以上的8个周期应用于背词法，作为一个大的背词循环的8个复习点可以最大程度的提高背词的效率
I have bought a new NetBook on Sunday and get it today. But unfortunately, it was just alive for about 10 hours then the screen didn`t work at all. What`s the hell of it.
I bought it on eBay, that`s web address http://bit.ly/12XwYP . The product is terrible but the seller KingWork is very good communicate and fast response
The GeoBee compantance which conducted by the National Grographic. The fininal winner is Eric Yang, I think he is a Chinese a guy and other two winnners are the Indina people. When I saw it, it`s really hard to say what I`m feeling. Chinese people could win almost any hard competition, but no western people admire that (more…)
在看<a beautiful mind>的时候看到了作者说的game theory中的新理论。集团利益的最大化不是个人的最大化。想让企业利益最大的时候，个人利益就会受损。这就像是蜜蜂的协同合作一样。他们每一员都能让最终的利益最大化，放弃的是短暂的个人利益，而用长期的集体利益去弥补自己个人利益的损失，并且这个弥补是超额的，是符合经济学原理的。蜜蜂不需要各种的game theory to guide thme, but they can do better that human beings.

我从前以为蚂蚁很清楚自己在做什么，列队爬过厨房整理台，看起来很有自信，所以我猜，它们心里肯定有一套计划，知道往哪儿去、该做什么。要不然，蚂蚁怎么有办法规划路线、建造复杂的蚁窝、发动波澜壮阔的突击行动……做出种种蚂蚁会做的事？
结果我错了。蚂蚁根本不是什么聪明的小小工程师、建筑师，或是战士——至少作为单独的个体时不是。在决定下一步要做什么这方面，大多数蚂蚁是一点概念也没有的。“你观察一只正在努力完成某件事情的蚂蚁，一定会对它的笨拙印象深刻。”美国斯坦福大学生物学家黛博拉·高登说。 (more…)

Don`t ask me, I `m still thinking.
Yesterday night, I am thinking about that why Google could be so sucesses. Then I found that it was because of the role of it. The position of it can`t be replaced by other company. As some new started search engine says it will defeat the Google in the future, such as Cuil.com and Worlframlpha.com (What a long web address 
) . But I think that it was impossible unless they change the way of people getting information. (more…)
