Вот оно как - Циолковского и американцы признаЮт:
"In their respective countries, three distinct individuals are most responsible for establishing the theoretical and practical basis for research into rockets and missiles. A Russian, Konstantin Eduardovich Tsiolkovsky, published a theoretical essay on space travel in 1903. Hermann Julius Oberth, a Romanian living in Germany,wrote an important, exhaustive, theoretical analysis in 1923. Robert H. Goddard, an eccentric New Englander, flew the first liquid-propelled rocket in 1926.Rocketry was first researched by Konstantin Eduardovich Tsiolkovsky, who could be considered the father of rocket science.
[italic = Non-conformist] He was a quiet, studious physics teacher and theoretical philosopher, who never flew a single rocket in his lifetime. Yet,Tsiolkovsky recognized four basic principles of rocket flight. First, reactive thrust is the key by which to achieve motion or acceleration in a vacuum. Second, the measure of thrust is achieved by the exhausted gases. Third, the speed reached by a rocket depends on the temperature of the combusted gases and the weight of the gases' molecular constituents. Last, Tsiolkovsky understood staged propulsion and the understanding of thrust-to-weight ratios."
