Отрывок из книги

For many people, astronomy has either remained on the covers of textbooks, or is a distant part of physics that is reluctantly studied in high schools and institutes. For modern man, surrounded by all sorts of irritants and living at a furious pace of the metropolis, every day it becomes more difficult to find time for himself, for questions to himself.

From early childhood to old age, we always have only one driving force-the desire to learn the unknown. The form of knowledge changes with age, but the brain’s thirst for new information remains the same. In childhood, we learn the world in all possible ways, and any information is new and interesting, but as we grow up, we find it difficult to find quality food for our brain, despite the fact that the requests remain the same.

Kepler’s third law (harmonic law): “The Squares of the periods of the planets’ rotation around the Sun are referred to as cubes of the large semi-axes of the planets’ orbits”. In other words, when a planet approaches the Sun, the radius (half – axis) of its orbit decreases, but the speed, and therefore the time of movement (period) – increases.

Only in 1609, with great agony, Kepler managed to publish his works, in which the scientist explained not only the new astronomy and physics of the sky, but also for the first time found out what is the cause of ocean tides. Kepler absolutely proved that the Moon is the cause of tides. It was also Kepler who introduced the term “inertia” into physics as the innate property of bodies to resist an applied external force, forming in a clear form the first law of mechanics: “Any body that is not affected by other bodies is at rest or performs a uniform rectilinear motion.”
