For instance, in one man's trial the DNA evidence statistic ranged from 1/95,000 to 1/13, depending on the different weighing methods used by the defense and the prosecution.
Thus mathematics may be defined as the subject in which we never know
what we are talking about, nor whether what we are saying is true.
