It is almost impossible for me to read contemporary mathematicians who, instead of saying “Petya washed his hands,” write simply: “There is a <math>t_1<0</math> such that the image of <math>t_1</math> under the natural mapping <math>t_1 \mapsto {\rm Petya}(t_1)</math> belongs to the set of dirty hands, and a <math>t_2</math>, <math>t_1<t_2 \leq 0</math>, such that the image of <math>t_2</math> under the above-mentioned mapping belongs to the complement of the set defined in the preceding sentence.”
