Not all rationals as binary expansions end with zeros, only multiples
of inverse powers of two, for any finite string of zeros and ones
there are expansions of rationals that end with those repeating.

"Thus, the claim that the non-zero
measure of fat Cantor sets arises
from relation with an atomic
measurable space whose atoms are
not singletons has been verified. "

Having measurable, countable, atoms, comprising units of measure:
what would be their character as sets of reals?
