-<note tip> +The flavor puzzle is the question why do the particles ​in the [[models:​standard_model|standard model of particle physics]] have the values they haveand why do the mixing angles in the PMNS and CKM matrix have the values they have.
-Explanations ​in this section should contain no formulasbut instead colloquial things like you would hear them during a coffee break or at a cocktail party. +
