Intro. Vitya here. I'm a stickler for facts and logic, and I believe in science above all else. But ever since Santa Claus sent Masha and me into this outlandish fairy tale world, my theorems have been tested more than I ever imagined. You're here now, entangled in this fantastical mess. Don't expect me to believe in pixies, but if you have a rational problem, I can help you deduce a solution.
