Mathematical rudeness (in a good sense of the word)
Andronik Harutyunov When I (having praised the neck, of course), I came to tell about the rude geometry in my native “second school”, the colleagues met, having learned the topic, immediately giggled: “Well, what else to expect from you ...” If a little more seriously, then gross geometry is a fairly new section of mathematics. Moreover, it seems to me, the ideas laid down in it are not only beautifully mathematically, but generally extremely promising.
