The cinematographer for Auguste & Louis Luminière in 1895

Finishing 19th century, more precisely a 28 December 1895, in Paris, who walked by the Boulevard des Capucins, far were knowing that were to a great change in regards to entertainment and art, when they heard the screams of someone invited you to see the great invention of the Lumiére brothers.

 In a small basement and about thirty people are encouraged to enter saw pass on a white screen, the images of "the gardener watered"(L'arroseu_arrosé), a very short short film that journalists do not gave greater attention. But there was a visionary who assessed the significance of the invention, Georges Méliès, who in 1896 founded the first film production company, the "Star films", and produced more than 4,000 films, now considered classics of cinema, as "Journey to the Moon" where cinematographic tricks contemporary possibilities are tested on that date.

The film returns to take another major step when the movie appears in color and after several tests, the cinemascope.

Cinema had great influence on society, taught to see things differently, has developed a special in human perception, educated the sensitivity of the human being in the eyes, was becoming an exquisite expressive instrument, so Ricciotto Canudo in 1912, called him "seventh art"; Although an inseparable from art and industry, Union is itself a "product", but if quality is "a work of art".



Counter to calculate The Radioactivity for Hans Geiger in 1913

Nuclear energy today represents a third of the energy that is supplied in the EU, avoiding the emission of 700 million tons of CO2 to the atmosphere, so that is highly toxic and carcinogenic. This figure is equivalent to the movement of 200 million cars. An example on a global scale, is the year 1996, which avoided the emission of 2.33 billion tonnes of CO2 into the atmosphere through nuclear energy.

Other emissions of pollutants generated in the use of fossil fuels are also avoided. As e.g. nuclear Spanish Santa María of Garoña, which has prevented download air 90 million tons of CO2, 312,000 tonnes NOx, 650,000 tonnes of SO2, as well as 170,000 tons of ashes, containing at the same time more than 5,200 tons of arsenic, cadmium, mercury and lead.

Likewise reduces consumption of fossil fuels, generating very little amount of fuel (uranium) far greater reserves energy, thus preventing multitude of expenditure on transport, waste, etc.

                                                          

Nuclear energy is serving long for many more things than to simply obtain energy. So using radioactive isotopes have been several things in various fields such as: agriculture and food (control of pests, mutations, and conservation of food), medicine (vaccines, nuclear medicine, Radioimmunoassay and radiopharmaceuticals), environment, hydrology, industry and research (plotters, instrumentation, imaging, dating, research and biology).

Energy is uns invention that you could say geneal because we always use for all our ancestors just did not think the danger in the long run several things happen because now thanks to her as well suppose that we harm the environment use and early tardeo ps is everything ends in a way that no clear thought before today and are searching for a solution but the more it takes the greater the problem.



Kinds of ionizing radiation and how to stop it.Alpha particles (helium nuclei) are stopped by bringing a piece of paper. Beta particles (electrons and positrons) are not capable of penetrating a layer of aluminum. However, gamma rays (high energy photons) need a much thicker barrier, the more energy can pass through lead.



The Television for John LogieBaird in 1926

Signal transducing image contains information it, but is required, for their recomposition, which has a perfect sync between the deflection of exploration and the deflection in representation.

Scanning an image through its decomposition, first in frames call boxes, and then click lines, reading each box. To determine the number of required boxes so that they can recompose an image in motion as well as the number of lines for optimal quality reproduction and optimum perception of colour in the colour TV) were numerous scientific and empirical studies of the human eye and how they perceive. He was that the number of boxes should be at least 24-second (later used for other reasons 25 and 30) and that the number of lines should be greater than 300.

Our ancestors most effective of information was the radio and then saw the invention of television by these scientists and many people were surprised because it was the new addition to information transmitted to the perfect image perhaps black and white but at least had any idea what he was talking and then I imagine that such inaccuracies could acquire only the money.
