Quotes by Scientist


"Science attempts to analyze how things and people and animals behave; it has no concern whether this behavior is good or bad, is purposeful or not. But religion is precisely the quest for such answers: whether an act is right or wrong, good or bad, and why."

"Laws alone can not secure freedom of expression, in order that every man present his views without penalty there must be spirit of tolerance in the entire population."

"Liberation from superstition is a necessary but not a sufficient condition for science."

"Many religions have attempted to make statues of their gods very large, and the idea, I suppose, is to make us feel small. But if that's their purpose, they can keep their paltry icons. We need only look up if we wish to feel small."

"We tend to hear much more about the splendors returned than the ships that brought them or the shipwrights. It has always been that way. Even those history books enamored of the voyages of Christopher Columbus do not tell much about the builders of the Nina the Pinta and the Santa Maria or about the principle of the caravel. These spacecraft their designers builders navigators and controllers are examples of what science and engineering set free for well-defined peaceful purposes can accomplish. Those scientists and engineers should be role models for an America seeking excellence and international competitiveness. They should be on our stamps."

"The American and Russian capabilities in space science and technology mesh, they interdigitate. Each is strong where the other is weak. This is a marriage made in heaven - but one that has been surprisingly difficult to consummate."

"But we have no [Marian] apparitions cautioning the Church against, say, accepting the delusion of an Earth-centered Universe, or warning it of complicity with Nazi Germany - two matters of considerable moral as well as historical import....Not a single saint criticized the practice of torturing and burning "witches and heretics. Why not? Were they unaware of what was going on? Could they not grasp its evil? And why is [the Virgin] Mary always admonishing the poor peasant to inform the authorities? Why doesn't she admonish the authorities herself? Or the King? Or the Pope?"


"As a rule, software systems do not work well until they have been used, and have failed repeatedly, in real applications."

"For ages men had used sticks to club and spear each other-Anaximander of Miletus used the stick to measure time."

"Look again at that dot. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every "superstar," every "supreme leader," every saint and sinner in the history of our species lived there--on a mote of dust suspended in a sunbeam."

"I am one of those scientists who feels that it is no longer enough just to get on and do science. We have to devote a significant proportion of our time and resources to defending it from deliberate attack from organised ignorance."

"If you have an idea, you will likely have difficulties during the process ofrealization regardless of the type of idea (scientific idea, invention idea,business idea, new product idea, brand idea, advertising idea, etc.)."

"I'm quite a softy, yes. I have a blank spot with respect to visual art, but I have perhaps a compensating hypersensitivity to poetry and music."

"It is a mistake, he said, "to suppose that the public wants the environment protected or their lives saved and that they will be grateful to any idealist who will fight for such ends. What the public wants is their own individual comfort."

"When we look at a solid lump of iron or rock, we are 'really' looking at what is almost entirely empty space. It looks and feels solid and opaque because our sensory systems and brains find it convenient to treat it as solid and opaque. It is convenient for the brain to represent a rock as solid because we can't walk through it. 'Solid' is our way of experiencing things that we can't walk through or fall throug, because of the electromagnetic forces between atoms. 'Opaque' is the experience we have when light bounces off the surface of an object, and none of it goes through."

"The unleashed power of the atom has changed everything save our modes of thinking and we thus drift toward unparalleled catastrophe."

"Consider again that dot [Earth]. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every "superstar," every "supreme leader," every saint and sinner in the history of our species lived there - on a mote of dust suspended in a sunbeam."

"If at first the idea is not absurd, then there is no hope for it."

"I have just got a new theory of eternity."

"It stands to the everlasting credit of science that by acting on the human mind it has overcome man's insecurity before himself and before nature."

"I don't think science is hard to teach because humans aren't ready for it, or because it arose only through a fluke, or because, by and large, we don't have the brainpower to grapple with it. Instead, the enormous zest for science that I see in first-graders and the lesson from the remnant hunter-gatherers both speak eloquently: A proclivity for science is embedded deeply within us, in all times, places, and cultures. It has been the means for our survival. It is our birthright. When, through indifference, inattention, incompetence, or fear of skepticism, we discourage children from science, we are disenfranchising them, taking from them the tools needed to manage their future."

"Perhaps if one less dragonfly had drowned in the Carboniferous swamps, the intelligent organisms on our planet today would have feathers and teach their young in rookeries. The pattern of evolutionary causality is a web of astonishing complexity; the incompleteness of our understanding humbles us."

"Be patient in life, knowing that there is a real possibility that the desired outcome could happen without your direct involvement."

"My religiosity consists of a humble admiration of the infinitely superior spirit who reveals himself in the slight details we are able to perceive with our frail and feeble minds. That deeply emotional conviction of the presence of a superior reasoning power, which is revealed in the incomprehensible universe, forms my idea of God."


"In the foreign country, we call the past, crucifixion was a common punishment. It was invented by the Persians, carried back to Europe by Alexander the Great, and widely used in Mediterranean empires."

"Science has taught us, against all intuition, that apparently solid things like crystals and rocks are really almost entirely composed of empty space. And the familiar illustration is the nucleus of an atom is a fly in the middle of a sports stadium, and the next atom is in the next sports stadium."

"It is interesting that it is not the getting of any sort of knowledge that God has forbidden, but, specifically, the knowledge of the difference between good and evil-that is, abstract and moral judgments, which, if they reside anywhere, reside in the neocortex."


"Instead of asking, "Why is there war? we might ask, "Why is there peace? We can obsess not just over what we have been doing wrong but also over what we have been doing right. Because we have been doing something right, and it would be good to know what, exactly, it is."

"It is the writer who might catch the imagination of young people, and plant a seed that will flower and come to fruition."


"America had, for one thing, lived in anarchy for - until much more recently than Europe. We had the Wild West, where the cliche of the cowboy movies was the nearest sheriff is 90 miles away, and so you had to pack a gun and defend yourself."

"I do think imagination is enormously valuable, and that children should be encouraged in their imagination. That's very true."

"We should take care not to make the intellect our god; it has, of course, powerful muscles, but no personality."

"She's qualified all right. She understands robots like a sister-comes from hating human beings so much, I think."

"Present global culture is a kind of arrogant newcomer. It arrives on the planetary stage following four and a half billion years of other acts, and after looking about for a few thousand years declares itself in possession of eternal truths. But in a world that is changing as fast as ours, this is a prescription for disaster. No nation, no religion, no economic system, no body of knowledge, is likely to have all the answers for our survival. There must be many social systems that would work far better than any now in existence. In the scientific tradition, our task is to find them."

"Billions of years from now our sun, then a distended red giant star, will have reduced Earth to a charred cinder. But the Voyager record will still be largely intact, in some other remote region of the Milky Way galaxy, preserving a murmur of an ancient civilization that once flourished - perhaps before moving on to greater deeds and other worlds - on the distant planet Earth."

"In the morning, people have a plan for that day. Hardworking people think of what they will do during the day, and idle people on what they should do."

"I prefer to make up my own quotes and attribute them to very smart people, so that I can use them to win arguments."
