Tsiolkovsky. The Path to the Stars

Who was Konstantin Eduardovich Tsiolkovsky? A modest teacher from Kaluga who made those around him laugh with his eccentricities, loved to skate using an umbrella, trimmed the hair of kids from the whole street on his porch, and launched kites for them? All of this is true, but the main thing is that he was a genius scientist. More than a hundred years ago, he invented the rocket that opened the way to the stars for humanity.
