there are no uninteresting numbers http://en.wikipedia.org/wiki/Interesting_number_paradox

[tlb]

Only applies to integers. Most real numbers are not interesting.

[philh]

Unless you assume the well-ordering principle.

[btilly]

That only makes them interesting relative to a given well-ordering. Since nobody knows the details of any well-ordering of the real numbers, this severely limits the interestingness of a given real number.
