"A scientific theory -- пишет Карл Поппер, -- an explanatory theory -- is, if anything, an attempt to solve a scientific problem, that is to say, a problem concerned or connected with the discovery of an explanation.[...] Problems crop up especially when we are disappointed in our expectations, or when our theories involve us in difficulties, in contradictions; and these may arise either within a theory, or between two different theories, or as a result of a clash between our theories and observations. [...] The conscious task before the scientist is always the solution of a problem through the construction of a theory that solves the problem; for example by explaining unexpected and unexplained observations."

Вот какая проблема сегодня cropped up:
8*. Петя и Миша имеют фамилии (sic) Белов и Чернов. Какую фамилию имеет каждый из ребят, если Петя на два года старше Белова? (Л.Г.Петерсон, "Математика, 1й класс. Часть 3").

Задумайтесь, друзья мои, о вселенной, в которой известно то, что дано, и неизвестно то, что спрашивается.
