Instead if we want this pointer to represent the address of something in as much as it points at that address let's just draw an arrow.
如果我们想要让这个指针表示,数据的地址,它指向的地址,我用一个箭头表示。
This refers to random variables that have fat-tailed distributions-- random variables that occasionally give you really big outcomes.
这就表示,服从长尾分布的随机变量,这些数据出现极端值的概率比较大

We're kind of guessing on these population figures.
而我们对于这样得到的人口数据的准确性,仍表示怀疑
So what data type can we use to actually get more bits of precision than an int?
所以我们能用什么数据类型来表示,比int类型更多位数的数呢?
But one of the teaching fellas also passed long to us recently, a little real world example of what happens when you're not mindful of various data types and you're not mindful of the imprecision that's inherent in representing data in a computer, at least using a language like C and low level primitives like floats and even doubles.
最近有个助教告诉我们,一个现实世界中的例子,当你不注意各种各样的数据类型,也不注意在计算机中表示数据时,其内在的不精确性,至少在用像C语言,和float甚至double型数据时,那将会发生什么?
