Reports that say that something hasn't happend are always
intersting to me,because as we know:
There are known knows,there are things
we know we know.
We also know that there are known
unknowns.that is to say we know there are sonmething we
don't know.
But there are also unknown
unknowns,they one we don't known we don'tknown.
it is the latter category that tend to be the difficult
ones.

当报告上说有些事情不曾发生,经常会使我感到有趣。因为:众所周知:
世上有已知的知,即我们知道我们知道的那些事情。
我们也知道这世上还有已知的未知,也就是说我们知道我们还不知道的那事情。
