Time and Calendar

In very ancient times, people did not have a correct idea of ​​the shape and size of our planet and what place it occupies in space. Now we know that the physical surface of the Earth, which is a combination of land and water, is geometrically very complex; it cannot be represented by any of the well-known and mathematically studied geometric figures. On the surface of the Earth, seas and oceans occupy about 71%, and land – about 29%; the highest mountains and the greatest depths of the oceans are negligible compared to the size of the entire earth. So, for example, on a globe with a diameter of 60 cm, Mount Everest with a height of approximately 8840 m appears as just a grain of 0.25 mm. Therefore, the body, limited by the surface of the oceans, in a calm state mentally continued under all continents, is taken for Continue reading
