Re: 20th century

Here we see the difference between COUNTING and MEASURING.

The First cm goes from the zero end to the 1 cm mark.

In the seventh grade I was told that counting could be absolutely
accurate (unless you got treipped up some how) but MEASURING could
NOT be arbitrarily accurate.

I maintain that we are counting years, decades, centuries, millennia
in this case.

Party NOW for the Y2K (changing of the digit)
Party THEN for the new millennium!

The angels that push the planets around told me it HAS to be
this way! ;-)

I do. I was taught, way back in undergrad, lower division days, to use
the 1 cm mark and subtract because one could not trust that the end of
the meter stick, ruler, scale, etc. had not been damages and
foreshortened from use.
