Nonsense. ℵo unit fractions cannot fit into one of the ℵo intervals between two of them.
(O, x) is NOT an interval between two unit fractions. It has, anyway,
the same length that another interval that is between two neighboring
unit fractions.
Ask one your students^H^H^H^H^H^H^H^H^H victims. They know better
than you.
