Konstantin Tsiolkovsky Quotes

Sometimes people wonder why aeroplanes are so cheap and rockets are so expensive. Even the most superficial comparison shows one obvious difference: aeroplane engines use outside air to burn their fuel, while rockets have to carry their own oxidisers along.

We will build new ships to carry man forward into the universe, to gain a new foothold on the moon and to prepare for new journeys to the worlds beyond our own.

When you launch in a rocket, you're not really flying that rocket. You're just sort of hanging on.

I do not remember how it got into my head to make the first calculations related to rocket. It seems to me the first seeds were planted by famous fantaseour, J. Verne.

We want to make sure we get living astronauts to the surface of Mars.

We haven't sat down with Scott and Caroline and said, Now you realize that there's X amount of pounds of thrust. And this can happen and that can happen.

Man must at all costs overcome the Earth's gravity and have, in reserve, the space at least of the Solar System.

From the moment of using rocket devices, a great new era will begin in astronomy: the epoch of the more intensive study of the firmament.

Your chemistry high school teacher lied to you when they told you that there was such a thing as a vacuum, that you could take space and move every particle out of it.

Juggling is sometimes called the art of controlling patterns, controlling patterns in time and space.

Once solved, the severe handicaps imposed on space exploration by the weight and chemical limitations of rockets would no longer apply. The whole timetable of our conquest of the planets in our solar system would be tremendously speeded up, from hot Mercury all the way out to frigid Pluto.

Man will not always stay on Earth; the pursuit of light and space will lead him to penetrate the bounds of the atmosphere, timidly at first, but in the end to conquer the whole of solar space.

In a field like acting, there is pressure of all kinds, and it becomes tricky to navigate this space. There isn't a particular path laid out to get what you want; you have to figure out ways to get there on your own. And yet, there is no guarantee of getting what you want. At times, you don't know whom to listen to or whose advice to follow.

In fashion, there's huge pressure to produce results in no time. But you cannot guarantee numbers, because fashion gravitates around desire.

... each of the 24 modes in the Ramanujan function corresponds to a physical vibration of a string. Whenever the string executes its complex motions in space-time by splitting and recombining, a large number of highly sophisticated mathematical identities must be satisfied. These are precisely the mathematical identities discovered by Ramanujan.

Alternate currents, especially of high frequencies, pass with astonishing freedom through even slightly rarefied gases. The upper strata of the air are rarefied. To reach a number of miles out into space requires the overcoming of difficulties of a merely mechanical nature.

Because now, you know, it's going to be a number of years yet before we have our own new boosters and new spacecraft to go to our own International Space Station and proceed with all the research that we spent $100 billion putting up there to give us that research capability for the future for people right here on Earth.

There is always competition. Whatever you do, there will be competition, and you have to decide how you’re going to play. For me, I had to be the very best. I had to be the very best. Because, if I was not the very best, I would end up being number two.

If we remembered everything, we should on most occasions be as ill off as if we remembered nothing. It would take us as long to recall a space of time as it took the original time to elapse, and we should never get ahead with our thinking. All recollected times undergo, accordingly, what M. Ribot calls foreshortening; and this foreshortening is due to the omission of an enormous number of facts which filled them.

Look out into the July night, and see the broad belt of silver flame which flashes up the half of heaven, fresh and delicate as the bonfires of the meadow-flies. Yet the powers of numbers cannot compute its enormous age,—lasting as space and time,—embosomed in time and space.

It's fantastic that Congress has an increasing number of women. Experts call an increasingly female presence in a previously male space 'the Bruce Jenner effect.'

No matter how many people are screaming your name or how many Number One hits you have, you can still wake up and feel like a loser.

The number of stressors has multiplied exponentially: traffic, money, success, work/life balance, the economy, the environment, parenting, family conflict, relationships, disease. As the nature of human life has become far more complicated, our ancient stress response hasn't been able to keep up.

The total number of stars in the Universe is larger than all the grains of sand on all the beaches of the planet Earth.

The number of habitable worlds in our galaxy is certainly in the tens of billions, minimum, and we haven't even talked about the moons. And the number of galaxies we can see, other than our own, is about 100 billion.
