The railroad originally was as completely dissociated from steam propulsion as was the ship -- John Moody
The Air Corps . . . does not, at this time, feel justified in obligating . . . funds for basic jet propulsion research and experimentation. -- George Brett
On Sunday August 5, 2012, I was among a group of people who witnessed the Rover landing on Mars in real time at NASA's Caltech-managed Jet Propulsion Laboratory in Pasadena. -- Ahmed Zewail
Really exotic methods of propulsion . . . will have to be devised to get there. How it will be done, I do not know. Whether it will be done, I am not quite certain. But I would bet it can be done. -- Edward Teller
The hazards posed by Near-Earth Asteroids are assessed by Sentry, a computer system developed by the Near-Earth Objects Group at NASA's Jet Propulsion Laboratory in Pasadena, Calif. The software factors together a cosmic rock's coordinates, distance, velocity, and gravitational influences to calculate its trajectory. -- Brendan I. Koerner
A pure heart is perhaps one which has no natural propulsion towards anything in any manner whatsoever. When in its extreme simplicity such a heart has become like a writing-tablet beautifully smoothed and polished, God comes to dwell in it and writes there His own laws. -- Maximus the Confessor
God spare me sclerosis of the curiosity, for the curiosity which craves to keep us informed about the small things no less than the large is the mainspring, the dynamo, the jet propulsion of all complete living. -- John Mason Brown
For the first time I was flying by jet propulsion. No engine vibrations. No torque and no lashing sound of the propeller. Accompanied by a whistling sound, my jet shot through the air. Later when asked what it felt like, I said, "It felt as though angels were pushing". -- Adolf Galland
The very first experiments with building rockets and firing them off were carried out by students at Cal Tech in 1937, '38 and '39. And later these people put together these jet propulsion labs in Pasadena and wound up sending aircraft and spacecraft to the moon. So it all began very primitively with love. -- Ray Bradbury
I'd like to get shot into space. I'd like to potentially visit the moon. I don't know if I can do that in the next couple years, but I spent some time at the jet propulsion lab, looking out at the future of when a guy like me can do a little space travel. -- Rob Dyrdek
I don't like to rate myself; others can do that. I've spoken with a number of young people who weren't even born in 1969, when the first moon landing was made. They've witnessed the first person to fly at faster than speed of the sound without propulsion. These kids are happy to have had such a momentous event in their lifetime. -- Felix Baumgartner
Drive over to the nearest airport, and enroll in flight classes. You will experience the joy of freedom in the air above, as you study the mechanics of how this is made possible by understanding the construction, the laws of motion, the air that can provide lift when it is moved by propulsion through the air, and stay above the gravity pulling the airplane back down to earth. -- Buzz Aldrin
Sex is perhaps like culture - a luxury that only becomes an art after generations of leisurely acquaintance. Why we scarcely approach either as individuals - it's mass propulsion still! -- Alice B. Toklas
Way before we were scratching pictures on caves or beating rhythms on hollow trees we were perfecting the art of combining our breath and mind and muscles into fluid self-propulsion over wild terrain. -- Christopher McDougall
it's a funny thing about Hollywood. Once you've been out here awhile, it's hard to go someplace else, and it gets harder the longer you stay here. Takes some real propulsion to make you leave. -- Pamela Moore
The genius of Man in our time has gone into jet-propulsion, atom-splitting, penicillin-curing, etc. There is none over for works of imagination; of spiritual insight or mystical enlightenment. I asked for bread and was given a tranquilliser. -- Malcolm Muggeridge
For decades, people have known the chemical-propulsion approach to space travel is really not going to get us that far. Chemical propulsion is essentially like the horse-and-cart approach to the exploration of the American West, instead of the steamboat or the railroad. -- Franklin Chang Diaz
In the increasingly mechanized, automated, cybernated environment of the modern world a cold, bodiless world of wheels, smooth plastic surfaces, tubes, pushbuttons, transistors, computers, jet propulsion, rockets to the moon, atomic energy man's need for affirmation of his biology has become that much more intense. -- Eldridge Cleaver
Chemical propulsion is obsolete to go anywhere other than the moon. Three days - that's acceptable. But for Mars, we need propulsion technologies to get us there in, say, 60 days - then spend whatever length of time we want to spend and return when we want to come home. -- Gene Cernan
We do need different types of propulsion to get to Mars. I wrote one of the first Ph.D. theses on that in the 1960s. -- Edgar Mitchell
If you stop and think about it, the form of propulsion used today hasn't changed in over a thousand years... since the invention of fireworks by the Chinese. -- Peter Diamandis
