discovering paradoxes

July 31, 2008

I didn´t know paradoxes where something you studied at Maths school… mi father studied maths and he always tries to teach us weird things… this was yesterday´s teaching during family dinner: paradoxes.

Some examples:

- “If there is an exception to every rule, then every rule must have at least one exception, the exception to this one being that it has no exception”

and one in Spanish…. I find translating a paradox too complicated…

- Había un barbero que decía que sólo afeitaba a quienes no se afeitaban a ellos mismos, pero entonces, ¿quién afeitaba a dicho barbero? no puede afeitarse él, porque él sólo afeita a quien no se auto-afeita, pero si le afeita otro, entonces debería afeitarse él…. (se entiende?)

More or less this is the Russell’s Paradox
