> they call the "0th" ordinal number by the name "first". We have never moved past the phase where the concept of "zero" was heretic. Even in maths it's pretty bad, because the Natural numbers still sometimes don't include 0, so that the 0th Natural number is 1, the 1th natural number is 2 etc. (using 1th instead of 1st to avoid the confusing nature of "first" in this discussion).
