Eubulide is the italian version of the name of the greek philosopher Eubulides (no, he's not the one in the image, that's Socrates), the inventor on the liar paradox.

My main interestests are:

Mathematical Logic: Kurt Gödel.

Classical music: my favorite composers are Antonio Vivaldi and Joseph Haydn. And Jazz: Duke Ellington.

Judo: with particular attention to Kata.
