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=

**Ø.**

And this is the reason of this blog!

Honestly, this empty set is a serious problem!
