It is certainly understandable to think that the differences between
aleph_0 (naturals) and c (reals) is related to the differences between
the discrete and continuous. Surprisingly though, they are unrelated.
For example, the rationals are continuous, but are only of size
aleph_0.

Hope that helps,
