Jaime Parejo dissected from the beginning, all existing training systems and involvement of search dogs (French, German, Swiss, American …), noting that basically limited to the simple application of operant conditioning (discovered by Frederic Skinner, based on that conduct positively reinforced tend to be repeated), classical conditioning discovered by Ivan Pavlov, shaping by successive approximations and introducing a greater or lesser extent, during the canine search behavior of certain directional commands. While it is true that these types of basic principles and processes of learning (the most simple associative learning mechanisms) are fundamental and essential logically for any type of search dog training, Jaime Parejo, verified repeatedly that were totally inadequate (even in those cases which were complemented with applications basically called canine cognitive training) for the proper and necessary operationally achieve high and especially canine cash exemplary performance in many types of search operations. Motivated by a strong parallel in humanitarian and also using its special drive and innate capacity for observation, analysis, hypothesis generation productive … about animal behavior, for twelve years would face an arduous and intense study and research work, strictly faithful to the general protocol of rigorous scientific research (focusing first on the behavior of the canine species in general and later in favor of fostering, the maximum possible degree of efficiency and effectiveness of the search dog in different situations). An important challenge finally offered as a result, Jaime Parejo, achieving its intended and difficult objectives, in October 1994 with the creation of so-called, Chest behavioral techniques associated with the respective educational process and even intervention operations, the method Chest (which named it one of their canine companions).

What is studying biology. You are beginning to study the basic biology (from the Greek words "bios" – the life and "logos" – the doctrine). Biology – the science of life, of living organisms that inhabit the Earth. Living organisms on our planet is very varied. That – and the people and animals, and plants, fungi and bacteria.

Scientists there are more than 3.5 million species of living organisms. They live on land, water, air. Scope of life is a special shell of the Earth – the biosphere (from the Greek words "bios" and "sphere" – a ball). The biosphere includes the lower atmosphere, water bodies, soil, the upper layer of the lithosphere. Biosphere area of distribution of life Biology studies the structure and vitality living organisms, their diversity, the laws of historical and individual development. All living organisms are closely related to each other and with the habitat. Living organisms affect the environment, and their existence depends on conditions of this environment. Section of Biology, who studies the relationship of organisms among themselves and with their environment is called ecology (from the Greek word oikos – a house, apartment, home – and "logos").

Let us recall the most basic concepts of speed, which teach in school, namely that speed – is a vector quantity. Those who remember that this vector is well known that the vector has a direction, moreover, the vector may not always be unidirectional. If time is inextricably linked with the speed that time – it's too vector quantity. And this is, in turn, suggests that it is tied to the direction of the velocity vector, that time can not be unidirectional, and this is quite easy to verify in practice. Take, for example, any movie. Until then, until we begin to view it, it does not speed, and hence the time it stopped. One may recall that a similar, we have already encountered when in the article "Speed" crossed the border the speed of light: no moving object in the form of material particles, so the movement of time is also absent. Including film, we turn and his time, and we can even adjust the speed of time.

And if we can turn in a movie clock? Without problems, but under one condition: we should have a movie player, remote control, so – and time. Without it, the movie with a given rate will move in one direction only. Does this example of an analogy with human life? Yes, the most direct. We move through life movie called "Destiny" in one direction and the one given velocity. Can a person change the speed and direction? Of course, can – this is the so-called time machine.
