Tsiolkovsky Quotes

Earth is the cradle of humanity, but one cannot live in a cradle forever.

A planet is the cradle of mind, but one cannot live in a cradle forever

Tsiolkovsky wrote: “The Earth is the cradle of mankind. But one does not live in the cradle forever.

The blue distance, the mysterious Heavens, the example of birds and insects flying everywhere —are always beckoning Humanity to rise into the air.

My main purpose in life is to do something useful for my fellow men, not to live my life in vain, to propel mankind forward, if only by a fraction. That is why I became interested in that which gave me neither bread nor power, but I am in hopes that my work, perhaps soon, perhaps only in the distant future, will yield society heaps of grain and vast power.

The world is desperately imperfect. Even if a quarter of the working people were engrossed in new thoughts and inventions and lived off the others, humanity would still gain tremendously thanks to the constant stream of inventions and intellectual work emerging from this horde of people striving upward.

To paraphrase K. E. Tsiolkovsky, the founder of astronautics: The Earth is the cradle of mankind, but one cannot live in the cradle forever.

Konstantin Tsiolkovsky in Russia, Hermann Olberth in Germany, and Robert Goddard in the United States all came up with an eerily similar concept for using liquid fuel to power rockets for human spaceflight. I've seen this pointed out as an odd coincidence, one of those moments when an idea inexplicably emerges in multiple places at once. But when I read through each of these three men's biographies I discovered why they all had the same idea: all three of them were obsessed with Jules Verne's 1865 novel "De la terre a la lune (From the Earth to the Moon)." The novel details the strange adventures of three space explorers who travel to the moon together. What sets Verne's book apart from the other speculative fiction of the time was his careful attention to the physics involved in space travel -- his characters take pains to explain to each other exactly how and why each concept would work. All three real-life scientists -- the Russian, the German, and the American -- were following what they had learned from a French science fiction writer.

The Earth is the cradle of the mind, but one cannot eternally live in a cradle.

All the Universe is full of the life of perfect creatures.

In terms of mathematics, the entire universe is alive, but the power of its sensitivity is manifested in all its brilliance only among the higher animals. All atoms of matter feel in keeping with the environment. Finding itself in highly organized beings, atoms life their life and feel their pleasure and pain. If they find themselves in the inorganic world, they sleep, as it were, immersed in a deep state of unconsciousness, in nothingness. Even in a single animal, as they wander around its body, the atoms live the life now of the brain, now of the bones, hair, nails, epithelium, and so on. Meaning that atoms now think, now live like atoms imprisoned in stone, water, or air. Now they sleep, with no awareness of time; now they live for the moment, like the lower beings; now they are aware of the past and paint a picture of the future. The more organized the being, the farther this notion of future and past extends.

Tsiolkovsky had no need for a lathe or a drill because he produced his results using the traditional tools of design engineering: pen and ink. He didn’t develop rockets; instead, he developed the rocket equation. He didn’t build liquid-fuel rocket engines; instead, he showed that liquid fuels would offer the highest performance.

Konstantin Tsiolkovsky (1857–1935), a reclusive, near-deaf, self-taught rural schoolteacher who, working alone and having almost no contact with the wider scientific community, invented ingenious engineering designs for multistage rockets, orbiting space colonies, and interplanetary craft. Though

Tsiolkovsky’s most well-known quote expresses this sentiment: “The Earth is the cradle of mankind, but one does not stay in the cradle forever.” Awakenings
