Interesting numbers in CS and Femi estimation (WIP)
There are some important numbers in CS, and remembering the level of these numbers can provide a more in-depth understanding of the computing system.
人是万物的尺度。对这些数字最好有个概念，就知道能处理的问题的量级是多少了，在书写项目书，指定相关指标的时候就能比较合理的进行估计。有了这些估计，我们可以用费曼估计法去快速推算一些比较复杂的问题。然后还能更好地理解计算机设备直接的unbalance的特性。
很多时候我们仅仅需要的是快速的量级的估计而不是精确的数字，这些问题都属于Feimi 估计的思路，比如最经典的某个城市大概有多少钢琴调音师等等。
