Sir Arthur Charles Clarke, CBE, FRAS (16 December 1917 – 19 March 2008) was a British science fiction writer, science writer and futurist, inventor, undersea explorer, and television series host.
Isaac Asimov is, in reality, based on something I had invented a few years previously.
Anything that is theoretically possible will be achieved in practice, no matter what the technical difficulties are, if it is desired greatly enough.
Don't mess up the environment until you're quite sure what you're doing.
Attempting to define science fiction is an undertaking almost as difficult, though not so popular, as trying to define pornography. . . In both pornography and SF, the problem lies in knowing exactly where to draw the line.
I have a fantasy where Ted Turner is elected President but refuses because he doesn't want to give up power.
I doubt if there is a single field of study so theoretical, so remote from what is laughingly called everyday life, that it may not one day produce something that will shake the world.
If there are any gods whose chief concern is man, they can't be very important gods.
When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong. Perhaps the adjective 'elderly' requires definition. In physics, mathematics, and astronautics it means over thirty; in the other disciplines, senile decay is sometimes postponed to the forties. There are, of course, glorious exceptions; but as every researcher just out of college knows, scientists of over fifty are good for nothing but board meetings, and should at all costs be kept out of the laboratory!
Space can be mapped and crossed and occupied without definable limit; but it can never be conquered. When our race has reached its ultimate achievements, and the stars themselves are scattered no more widely than the seed of Adam, even then we shall still be like ants crawling on the face of the Earth. The ants have covered the world, but have they conquered it for what do their countless colonies know of it, or of each other?
The space elevator will be built about 50 years after everyone stops laughing.
All explorers are seeking something they have lost. It is seldom that they find it, and more seldom still that the attainment brings them greater happiness than the quest.
The greatest tragedy in mankind's entire history may be the hijacking of morality by religion.
A wise man once said that all human activity is a form of play. And the highest form of play is the search for Truth, Beauty and Love. What more is needed? Should there be a ‘meaning’ as well, that will be a bonus? If we waste time looking for life’s meaning, we may have no time to live — or to play.
Until we get rid of religion, we won't be able to conduct the search for God.
As three laws were good enough for Newton, I have modestly decided to stop there.
Any sufficiently advanced technology is indistinguishable from magic.
Every revolutionary idea seems to evoke three stages of reaction. They may be summed up by the phrases: 1- It's completely impossible. 2- It's possible, but it's not worth doing. 3- I said it was a good idea all along.
Only small minds are impressed by large numbers.
Open the pod bay doors, Hal.
It is vital to remember that information - in the sense of raw data - is not knowledge, that knowledge is not wisdom, and that wisdom is not foresight. But information is the first essential step to all of these.
