Nature is unspeakably woman magazine amazing. All the phenomena around us are natural phenomena, and they can understand. If after many years of learning science at school forgot all the details, and adopted only the upper argument, we'd know a lot. Unfortunately, this is far from the typical attitude that build upon completion of schooling. For most nature remains boring and natural phenomena difficult woman magazine and incomprehensible. Comfort then a belief in the supernatural. woman magazine Its proponents Nobody has a problem understanding the potential. They, on the contrary, emphasize the value of the alleged incomprehensible. Accepting such a position are not only deprived of the joy of understanding nature than become a breeding ground for various scammers and sellers fog. The situation is further exacerbated few prolupalih scientists at its end of his career, rather than the promotion of science, turning the glorification of the supernatural. For now I will not deal with these sad things on his or unspeakable harm they do to society. woman magazine I dedicate this cycle, rather, the promotion of science. woman magazine I argue that the basic scientific concepts of natural pojavava can, and must, be understandable to everyone. My first example is the second law of thermodynamics.
WHAT'S Second Law of Thermodynamics woman magazine Second Law of Thermodynamics (hereafter 2zTd) is one of the most unquestionable laws of nature. It can be expressed in many different ways, all of which boil down to the same thing over heat engine, Perpetuum Mobile, entropy ... But first I have to mention the first law of thermodynamics and the concept of energy. Energy - with space, time and matter - one of the most fundamental concepts in physics. The universe can be described as a space that spreads over time, and to meet energy and matter. Space and time are closely related woman magazine and the substance (or substances) and energy. In the theory of relativity can be described woman magazine by the unique concepts of space-time and tvarienergije. But that's another story. Suppose now that energy and matter can be converted into each other, and that the energy measure which describes the ability of the material bodies in space that are rescheduled. In other words, the body's ability to move. Primary energy is the definition: "the body's ability to perform the work." A work (as well as heat) is the "energy of the transition." Part of the energy that passes from one body to another, or from one part of the system (a multitude of body) to another part of the system. That part of the energy is, in most cases, woman magazine the part that is, from our perspective, is useful. The first law of thermodynamics (thermodynamics is part of physics that describes the movement of energy, such as mechanics describes the motion of matter) tells what happens to the heat given off by the system: woman magazine the heat goes into operation, a portion of the internal energy of the system. In short, the first law of thermodynamics states that energy is only rescheduled, but does not disappear. He is, in fact, only a special form of a more general law - the law of conservation of energy - according to which the total energy of a closed system constant in time: it can not be created (out of nothing) woman magazine nor destroyed woman magazine (converted into anything). A key part of the statement woman magazine refers to a closed system. By this we mean a physical system (a collection of material bodies and energy) that is separated from its surroundings. In particular, no alternates its contents (either energy or matter) with the environment. So, in a closed system energy can be converted from one form to another, from one form to another, from one form to another ... But there's a catch. The amount of these changes is limited. In each of the changes of the energy goes into such a form that is no longer woman magazine suitable for the new posts. Figuratively, we can say that in a closed system energy "weak" in performing useful work. This is precisely 2zTd. A closed woman magazine system ultimately achieved a state in which no changes are no longer possible. This condition is called heat death. Of the many expressions 2zTd probably the simplest one that is, 1850th year, formulated by the German physicist Rudolf Clausius: Heat can not spontaneously jump from a lower body temperature, the body temperature more. Can (as you can and water uphill) only when there is an external force, or interaction with the environment. woman magazine But then the system is no longer closed. ENTROPY AS A MEASURE OF DISORDER 2zTd often described through the heat engine. woman magazine Heat engine woman magazine is any device that converts heat into work: the first efficient steam engine that was perfected by James Watt engine last model Farrarija. Extremely abstracted heat engine consists of two heat reservoirs: the warmer and colder. At the turn of energy (and this energy in turn is called heat) from the warmer to the colder reservoir, part of the energy (which does not exceed the colder reservoir) is RAD. To get the work (that part of the energy that is beneficial to us) one of the heat must cross the cooler tank. You can not create heat engine without cooler tank that would carry out the work so that draws power only from the warmer tank. This would not be disrupted by the first law of thermodynamics, but it was marred by others. Furthermore, the first two laws of thermodynamics can be expressed through of Perpetuum Mobile - hypothetical
