This article presents a comprehensive analysis of the circumstances surrounding the deaths of all deceased presidents of the United States of America. Based on historical documents, medical reports, and expert assessments, the chronology and causes of death of American heads of state are reconstructed. Particular attention is devoted to the eight presidents who died while in office, including four who fell at the hands of assassins and four who succumbed to natural causes. Statistical analysis covers natural mortality, assassinations, illnesses concealed from the public, as well as unique historical coincidences associated with the dates of presidential deaths.

Einstein's theory owes much of its notoriety to the so-called "twin paradox." This is probably because people want to live longer. The concept is simple: one twin stays on Earth, while the other travels at near-lightspeed to distant stars in a spaceship, and upon reaching the stars, they return to Earth using the same means and at the same speed. According to the equations of the theory of relativity, the astronaut will appear much younger than the stay-at-home twin upon their reunion.

There is a lot of information about the moon in textbooks, scientific and non-scientific publications. But there are so many dubious ones among them that one can't help but think of some terrible secret connected with the Moon. Analyzing the features of the manifestation of lunar phenomena for their compliance with scientific interpretations, one comes to the conclusion that the conspiracy theory is this is quite a sound theory. First, let's show the fallacy of the official opinion that the Moon rotates on its axis, although it always turns one side towards us.

A review is given of our present knowledge of different parametrization of experimental results in inelastic scattering process with polarized proton beams. Spin observables in polarized proton reactions for a set of lightweight nuclei are studied at intermediate energies in the region of 100–500 MeV. Two important types of DWIA calculations are used in the analysis of experiments. Important spin observables representing the difference functions (P–Ay) and (P–Ay)σ are examined along with the polarization-transfer coefficients Dij in inelastic scattering of polarized protons. The indicated value of σ is the differential cross section. These spin observables are treated in the context of the exchange features of the effective interaction.
