{∅, {∅}, {∅, {∅}}} : Rage Against the Meat Grinder

Hentrich,
I am not in a position to say anything about mathematics. The only thing I can say here is that almost thirty years ago the Ministry of Education changed the entire school program. Although this program had many flaws, at least one could learn but now the students have so many subjects they can hardly learn well. It is all confusing. As I understand there is a conspiracy against education here, there, everywhere. We have the Facultad Politécnica whose budget has been reduced. After all why would they need mathematicians if it is better to spend that money on blond secretaries for the  politicians. This world is a joke.

I think with that those vitamins you take, you are going to endure many nights of hard study.

Stay safe.
