When today people talk about Yemen, the news almost always feature the same words: war, hunger, destruction, attacks on ships, bombings. But if you look a bit closer and dig deeper, it becomes clear: war is just the tip of the iceberg. Yemen has long lived not just outside the 21st century, but somewhere in a parallel reality, where the state as such does not exist, and in its place are tribes, religious leaders, and armed groups.

This article examines the Roswell Incident—an event that became the cornerstone of modern ufology and conspiracy theories about the US government concealing contact with extraterrestrial civilizations. Based on analysis of historical documents, official US Air Force reports, and journalistic investigations, the true chronology of the July 1947 events and their subsequent mythologization is reconstructed. Particular attention is devoted to Project Mogul as the actual source of the debris found, the role of ufologists in creating the legend, and the transformation of a small New Mexico town into the epicenter of a global tourism industry built on belief in aliens.

This article examines the hypothetical scenario of a full-scale nuclear war and assesses the potential of various countries to survive under conditions of global catastrophe. Based on analysis of scientific research and expert assessments, the key factors determining a nation's and its population's ability to endure a nuclear conflict and subsequent nuclear winter are reconstructed. Particular attention is devoted to researchers' conclusions that only a limited number of countries, primarily located in the Southern Hemisphere, possess the necessary conditions for maintaining agricultural production and social stability in the post-apocalyptic period.

This article presents a comprehensive biography of Sir Isaac Newton, one of the most influential scientists in human history whose work fundamentally transformed humanity's understanding of the physical universe. Based on analysis of historical documents, scientific treatises, and biographical accounts, this article reconstructs Newton's trajectory from a solitary Cambridge scholar to President of the Royal Society and Master of the Mint. Particular attention is devoted to his groundbreaking contributions to physics, mathematics, optics, and astronomy, as well as his lesser-known pursuits in alchemy, theology, and chronology. The complex personality of Newton—secretive, intensely focused, and intellectually relentless—emerges as inseparable from the revolutionary ideas that laid the foundation for classical mechanics and dominated scientific thought for three centuries.
