哈福德认为，一些不可避免的干扰往往会让日常待办事项列表变得没有效率，而在这样的列表中留出即兴发挥的空间可以收获最佳效果。

Harford argues that inevitable distractions often tender the daily to-do list ineffective, while leaving room for improvisation in such a list can reap the best results.

而在缺陷小鼠中，信息传递效率较低甚至根本不发生。

And in our mouse model, the information transfer was less efficient or was unable to take place at all.

明显的是鱼的速度（最多70kph ）和极端游泳效率，其身体结构的进化可以减少阻力，从而在海洋移动中保存了体力。

These are evident in the fish’s speed (up to 70kph) and extreme swimming efficiency, evolution having honed its body to reduce drag and thus conserve strength during transoceanic migrations.

That in many cases, I can gain efficiency if I'm willing to give up space. Having said that though, there may still be a problem, or there ought to be a problem that may be bugging you slightly, which is how do I guarantee that my hash function takes any input into exactly one spot in the storage space?

普遍存在的增益和权衡,在许多的例子中,可以通过牺牲空间而得到效率方面的增加,话说回来，仍然存在一个问题,或者应该会有一个问题困扰着你,就是我如何保证我的哈希函数能够准确将,任一输入映射到相应的唯一的存贮空间中去？
