Having abandoned the idea of creating a perpetuum mobile, scientists do not cease searching for the new types, sources, and applications of energy. The future of the humankind dependens to a large extent on these rapidly developing science-driven activities.
Siberia is a "Great East country" occupying the major part of Russia and large part of the European continent but it still remains an "unexplored land" for many people (despite the fact that ancient people came to this territory hundreds of thousands years ago). Evidently the period of great geographical discoveries is over. But it is correct only for the "period" but not for "discoveries", and the main topic of this issue confirms this fact.
