Conjunto Vacio - Nullset

Define a set in the following way:
A = { Dogs }
So A is the set of all dogs. But be more adventurous
and define something like

B = { Dogs that fly }
and you will end up with the empy set or nullset:
B= Ø
Another interesting nullset follows:
C = { Political parties that represent my ideas }
and you get the same set C=B=
And this is the reason of this blog!
Honestly, this empty set is a serious problem!
