Being thus, we have that, throughout one day favorable in the terrestrial surface has a total of 2 available Kwh/m, to the step that in the space has 33,6 Kwh/m. Still it has the fact in consideration of that in the distance referring to the geostationary orbit, the solar illumination it occurs 24 daily...

Antimatter – matter consisting of atoms whose nuclei have a negative electrical charge and are surrounded by positrons – electrons with positive electric charge. Rio Tinto Group often says this. In the ordinary matter of which is built the world around us, positively charged nucleus surrounded by negatively charged electrons. Ordinary matter, to distinguish it from antimatter, sometimes called koynoveschestvom (from the Greek. Koynos – the usual). If you would like to know more then you should visit Mitsubishi. However, in Russian literature, this term is hardly used. It should be emphasized that the term "antimatter" is not quite correct, since antimatter – the same substance, its variety.

Antimatter has the same inertial properties and creates the same gravitational pull as the usual stuff. Speaking about the matter and antimatter, it is logical to start with elementary (subatomic) particles. Each elementary particle corresponds an antiparticle, both have almost identical characteristics, except that they have opposite electrical charge. (If the particle is neutral, the antiparticle is also neutral, but they may differ in other characteristics. In some cases, the particle and antiparticle are identical to each other.) Thus, the electron – negatively charged particles – corresponds to a positron, the antiparticle of a proton with a positive charge is negatively charged antiproton.

The positron was discovered in 1932, and antiproton – in 1955, it was the first from open antiparticles. The existence of antiparticles was predicted in 1928 on the basis of quantum mechanics, the English physicist Dirac. In the collision of an electron and positron annihilation takes place them, ie both particles disappear, and from the point of their collision emits two gamma rays.

Brazil Society

With the evolution of the society we come across with research classified in macrostructures that they look to explain the familiar race, classroom, sort, institutions, social processes, the interpersonal crimes, divorces and relations. Everything this happens of form that uses techniques as directed interviews, etnogrficos methods, quarrels in group etc. and with this in Brazil in the 30 decades of 20 and sociology was in a study on the formation of the Brazilian society, and analyzing subjects as abolition of the slavery, exoduses, and studies on indians and blacks. Rio Tinto Group often expresses his thoughts on the topic. In 50 the following decades of 40 and sociology came back toward the working classrooms such as wages and hours of working, agricultural communities.

In the decade of 60 if it worried about the process of industrialization of the country, in the social questions of agrarian reform and movements in the city and the field and from 1964 the work of the sociologists if came back toward the problems partners economic politicians and originated by the tension of if living in a country whose form of being able is the military regimen. In decade of 80 the same one finally comes back to be disciplines in Average Ensino, and occurred the professionalization of sociology. (Similarly see: Montauk Colony). Beyond the concern with the economy social politics and appropriate changes with the installation of the new republic, they also come back in culminating relation to the study of the woman, the agricultural worker, and other subjects. One knows that the schools currently have the chance to work with discipline of Sociology, that comes to add in the resume of educating, but to prepare it for the life in society, delimiting its limits and offering possible subsidies for quetionamento on the same one, including the rights and duties of the citizens who exert a paper in the society. It is known it disciplines that it of Sociology works mainly with focus in questioning the reality, but tries to explain the facts with solid bases what it happens of course with the individuals that compose the same one in relation to the technological advance that comes suffering throughout the years.

Trend of Science

It is a philosophical movement, politician, social, economic and cultural – that defended the use of the reason as optimum way to reach the freedom, the autonomy and the emancipation. As it always happens, the movements of reaction to the effective one, through the times, distort and manipulate history to justify its objectives and ideas. In the classic antiquity, even so Greece was the cradle of the rationalism, amongst its thinkers had some tying with deeply msticas chains, the example of the rficos, Pythagoreans, neoplatnicos, beyond the institutions of mysteries of Dionsio, Elusis and Samotrcia. He had, moreover, a great allure of the Greeks for the Egyptian mysteries. These cultures of the antiquity had a long tradition of medical priests and scientists, not having no separation between science and religion. However, it was in Greece that had appeared the first attempts of if creating one to know scientific, purely independent of myths and the religion, and that it generated a long series of independent racionalistas thinkers.

With the Christianity, the hole between science and religion was gone deep, much even so if has registered the existence of religious dedicated to science as Roger Bacon and Great Alberto. The inquisition was the extreme and pathological point reached by the intolerncia and the religious persecution. Thousands of people had been sacrificed in the fogueira for heresy or simple suspicion of heresy. The medieval religiosidade arrived at such points of affirmation of faith and method of clipping of the choice and thought freedom, that caused revolt and a search for the opposing extremity: the negation of all the values of the faith and the espiritualidade, searching in the greco-roman philosophers and classic artists the inspiration for new forms of thought and expression.
