, Tolstoy was an advocate of non-resistance only because he was protected from people’s impudence by his innumerable friends.
All the Universe is full of the life of perfect creatures.
The blue distance, the mysterious Heavens, the example of birds and insects flying everywhere - are always beckoning Humanity to rise into the air.

About this person
Konstantin Eduardovich Tsiolkovsky was born on 17 September 1857 and spent most of his life in a log house on the outskirts of Kaluga, about 150 km southwest of Moscow. A recluse by nature, his unusual habits made him appear eccentric to his fellow townsfolk, but the work he produced there laid the theoretical foundation for modern rocketry and astronautics. Along with Hermann Oberth and Robert H. Goddard, he pioneered the science of space flight when it existed only on paper. His works later inspired Wernher von Braun and leading Soviet rocket engineers Sergei Korolev and Valentin Glushko, who turned his equations into the vehicles that carried the Soviet space program to success. He died on 19 September 1935, two decades before the first satellite proved him right.
