If uncountably many real numbers should be distinguished ort be
applied for any mathematical reason, then all infinitely many digits
of each of them have to be written, because by shorter names only
countably many numbers can be distinguished or applied. Compare the
countable set of all finite subsets of |N.

A mathematician would know that.
