But if the concept of 'time' in general and the 'moment' in particular, to determine not how Newton – abstract duration, and Aristotle – the time is the number of motion, ie time there is a sequence of all the changes that take place in the world, changing it. If any, even the least moment is determined occurred at this moment some lifestyle changes Mir elements, including changing the spatial position of arrows, in this case it turns out that if the flying arrow does not change its spatial position, then, consequently, there was no, even the smallest, moments. No change – no time. In aporia 'Stages' Zeno puts a thought experiment, where time is understood not as a sequence of changes, and how abstract duration, which has the smallest indivisible and more value – 'atom' of time. Space is understood not as the relative positions of elements forming the world as well as a container for objects in the world, also has the 'atom' space. In the experiment, two objects are moving past the third in opposite directions with velocities relative to this third object in the space of one atom per atom of time. This means that with respect to each other, they move with a speed of one atom of space for half an indivisible atom of time.
Again a contradiction. Creates a problem, he knows the solution. Zeno knew that there are no atoms of space and time. Knew that any moment is determined by an infinite number of changes, the product who followed that moment with the way the world elements. .
Extinction in the middle of the upper Cretaceous period 80 million years ago, there were hundreds of species of dinosaurs, which covered the 14 families, of which two families were carnivorous, others feed on plants. All but members of one family of numerically small, were true giants and weighed more than 2-3 tons. Then the number of families and species of dinosaurs became gradually decrease. In the last five million years of the Cretaceous period, this process is accelerated, and the herbivores disappear faster than carnivores. Finally, 65 million years ago, giant reptiles disappeared completely. What was this caused by the gradual decline and ultimate extinction? Change Many paleontologists believe climate that the immediate cause was climate change. Dinosaurs were in need of warmth.
Their evolution proceeds in the climatic conditions are extremely different from the present. The average annual temperature on Earth was higher, and in such northern regions as Alaska, the climate was almost tropical, and within a year the temperature was almost everywhere even without such sharp distinctions between the seasons, as in our time. About Eighty million years ago, when dinosaurs began to disappear from the face of the Earth, temperatures around the world began to fall gradually, and also the difference between the extreme values of its annual has become much more. Nevertheless, even 50 north latitude found many fossils of dinosaurs end of the Cretaceous period, so that, apparently, and at that time – when they became extinct on our planet was a lot of areas with high and stable temperature. .
Waha Dizigov. For the first time the effect of standing waves was discovered by Nikola Tesla, and only after more than five decades, this effect was more thoroughly investigated, and became known as the "Schumann Resonance." The assumption of the existence of the resonance of electromagnetic waves in the Earth-ionosphere expressed in years, 50s, Professor, University of Munich, Otto Schumann. For 60 years, after numerous studies and rechecking was accurately determined standard frequency 7.83 Hz of the Earth. Since then, in science, this frequency is called the Schumann resonance frequency of a wave or Schumann. Some scientists and researchers all frequency radiation of the Earth is often called waves Shumana.V now frequency of 7.8 Hz is the main instrument for magnetic therapy. Earth and the surrounding air layer is formed giant spherical cavity. In terms of radio engineering are two huge areas that are placed in a druguyu.Mezhdu they are cavity bounded by conducting surfaces.
In this cavity, according to experts, a well-defined waves propagate dliny.Krome chastototy Schumann also identified other frequencies – 8, 14, 20, 26, 32 Hz. It is believed that at higher frequencies, the resonances are almost invisible. These frequencies are practically identical with the frequencies of alpha and beta rhythms of the human brain. Experts divided brainwaves into four categories, each corresponding to a particular level of consciousness. The unit of measurement of brain waves – as is the case with sound waves – is hertz (Hz). 1. Beta waves, from 14 to 20 Hz.
