Urban sociologists and anthropologists occasionally have common goals with geographers and engineers who work with satellites: to observe the social reality of a city where the conflict, as in the case of Baghdad, preventing both the direct observation of walking street as the maintenance of reliable databases. This is the argument from history that led to ADN. Tracks of the war in the lights of Baghdad. Cities have always defended the tangled ethnographic approximation to the city. Approached her and her people to hear first hand what is happening there.
Konstantin Eduardovich Tsiolkovski (Izhevskoye, Russia, Sept. 17, 1857 – Kaluga , Id., 1935), Russian physicist.
Born in Izhevskoye in the province of Ryazan, south of Moscow. Fifth son of a Polish immigrant, Tsiolkovski was educated by his own account in the libraries of Moscow and in the books of his father, because I could not attend school. In the ten years, a fever resulted in a loss of hearing. The problem is reason to try and overcome that could be as good as people without disabilities.
Prominent pioneer of astronautics. In his most important work, space exploration COSMICO through jets (1903), advance theories of modern astronaut and exhibited for the first time the possibility of traveling through the extra space by the rocket propulsion reaction. The connection of masses in the rockets, and the fundamental formula of astronautics, as a result of this, the proposed system of rockets targeted, then universally adopted system. He also proposed the replacement of the solid fuel which was used in the epoch by liquid propellant, which provided higher returns. I publish more than 500 works on space travel and related topics.
His notebooks are filled with sketches of liquid propulsion rocket, with detailed designs of handling pallets in the plume of extractor for directional control, double cabins pressurized to protect against meteors, detailed designs of combustion chambers, gyroscopes to control altitude, rest seats to protect against large acceleration during take-off and air bags G to exit the spacecraft in the vacuum of space.
The basic work of Tsiolkovski after 1884 is connected to four major issues: the scientific justification of a metallic balloon (airship), the airplane aerodynamics, the train glides through the air, and the means for interplanetary travel. After having met Nikolai Zhukovski student Stoletov, Tsiolkovski started to look at the mechanical flight control, and as a result designed the aircraft. At first, Tsiolkovski proposed the idea of aircraft covered entirely of metal (dirigible), and built its model work, I think the automatic flight control of the airship and circuits to control his elevation. Frequently Robotics has said that publicly. In 1897 I think the first wind tunnel Russian, and included the experimental process.
In the period 1892-1935 lived and worked in Kaluga. The reason for his transfer to Kaluga was a promotion. He lived with his family in the house which is now a part of the museum from 1904 until his death in 1935. It was here in Kaluga who became a scientist acknowledged, and where they wrote and published his theories of space flight and interplanetary journeys. Cosmic Philosophy wrote in Kaluga, playing on the distant future of humanity, including the eventual conquest of space and our solar system. In 1919 it appointed a member of the Socialist Academy of Social Sciences (in Russian: ).
Their ideas made it possible for human beings put into orbit the first artificial satellite, and shortly after that first flew into space, when Yuri Gagarin was placed in orbit around our planet in a rocket built according to principles laid down by Tsiolkovski.
