Science Quotes – Insightful Reflections on Research and Knowledge

"In Newton’s day, the Ptolemaic system and the Keplerian version of the Copernican system were taught side by side in the universities of the world. But the pendulum of belief had swung irreversibly to the Copernican side. In the minds of most scientists, the heliocentric universe had become fact…Yet there remained a crucial missing element in what was otherwise a complete and compelling picture of the universe: Not one shred of indisputable observational proof existed that the Earth moved through space.Here then was the holy grail of many an astronomer. To prove that the Earth in fact revolved in a wide orbit around the Sun, the parallax of just one star – any star – had to be detected. The hunt for stellar parallax was on."

Alan Hirshfeld

"The struggle, so violent in the early days of science, between the views of Ptolemy and Copernicus would then be quite meaningless. Either CS [coordinate system] could be used with equal justification. The two sentences, “the Sun is at rest and the Earth moves,” or “the Sun moves and the Earth is at rest,” would simply mean two different conventions concerning two different CS."

Albert Einstein

"The popular narrative about climate change reflects a dangerous corruption of science that threatens the world’s economy and the well-being of billions of people. Misguided climate science has metastasized into massive shock-journalistic pseudoscience. In turn, the pseudoscience has become a scapegoat for a wide variety of other unrelated ills. It has been promoted and extended by similarly misguided business marketing agents, politicians, journalists, government agencies, and environmentalists. In my opinion, there is no real climate crisis. There is, however, a very real problem with providing a decent standard of living to the world’s large population and an associated energy crisis. The latter is being unnecessarily exacerbated by what, in my opinion, is incorrect climate science."

John Francis Clauser

"Science is more than a body of knowledge; it is a way of thinking. I have a foreshadowing of an America in the time of my children or grandchildren – when the United States is a service and information economy; when Almost all major manufacturing industries have moved to other countries; when terrible technological powers are in the hands of too few, and no one representing the public interest can understand the issues; when people have lost the ability to set their own agenda. Lost or deliberately questioned by those in power; when, holding our crystals and nervously consulting our horoscopes, our vital faculties decline, in distinguishing between what feels good and what is true Unable, we go back to superstition and darkness, almost without noticing.

America’s downfall is most evident in the slow decay of real content in the most influential media, 30-second sound bites (now down to 10 seconds or less), credible presentations on lowest common denominator programming, pseudoscience and superstition, but especially From a kind of celebration of ignorance."

Dr. Carl Edward Sagan

"Science delusion is the belief that science has already fundamentally understood the nature of our reality and only the details need to be completed. I believe this is a seriously flawed view. Most people's first reaction is one of disbelief and rejection when they first hear this statement. How could there actually be anything more successful than science? It has given us cell phones, computers, airplanes, advanced forms of surgery, and much more. We have huge advantages today through science and through its technical applications. It looks as if there is no more room for error or even delusion there, and yet I maintain that at the innermost core of today's sciences there are fundamental errors of thought and dubious assumptions, and that there is a conflict within the sciences that keeps them from their proper task. I see science as a method of inquiry, a tool for exploring and investigating reality. But there is another side to the sciences, namely science as a worldview or even as a dogmatic belief system. Again, most people are shocked at first when I suggest that science can be a dogmatic belief system. They then say things like, "Hey, science in particular is the only thing that is possible for us and to leave our dogmatic belief patterns. It's the only discipline that produces tangible evidence, full respect, free inquiry, and open thinking." Now, this is the ideal of the sciences, and it is an ideal that I also share. But unfortunately, in practice, this ideal is usually not realized in the way it is preached. Within the sciences there is a strongly defined corset of beliefs that most scientists do not even suspect could be beliefs. They do believe that other people have beliefs-Christians, Buddhists, Muslims, and so on-but they themselves, of course, have no beliefs because they are, after all, concerned with scientific truth. And these beliefs are taken as such settled, established truths that they are usually not even discussed. When you study science, people don't just tell you what beliefs to accept and what things to know. You just absorb these principles like the process of osmosis in biology. These are things that are treated with such a matter of course that you just assume they must be true. Most people outside the scientific world assume that they must be true because science is simply so successful and, as a result, enjoys an enormously high level of prestige today."

Rupert Sheldrake

"Science alone of all the subjects contains within itself the lesson of the danger of belief in the infallibility of the greatest teachers in the preceding generation (…) When someone says, “Science teaches such and such,” he is using the word incorrectly. Science doesn’t teach anything; experience teaches it. If they say to you, “Science has shown such and such,” you might ask, “How does science show it? How did the scientists find out? How? What? Where?” It should not be “science has shown” but “this experiment, this effect, has shown.” And you have as much right as anyone else, upon hearing about the experiments–but be patient and listen to all the evidence–to judge whether a sensible conclusion has been arrived at. (…) The experts who are leading you may be wrong. (…) I think we live in an unscientific age in which almost all the buffeting of communications and television-words, books, and so on-are unscientific. As a result, there is a considerable amount of intellectual tyranny in the name of science."

Richard Phillips Feynman

"Although human ingenuity may devise various inventions which, by the help of various instruments, answer to one and the same purpose, yet will it never discover any inventions more beautiful, more simple or more practical than those of nature, because in her inventions there is nothing lacking and nothing superfluous; and she makes use of no counterpoise when she constructs the limbs of animals in such a way as to correspond to the motion of their bodies, but she puts into them the soul of the body"

Leonardo da Vinci

"One day the world will look upon research upon animals as it now looks upon research on human beings"

Leonardo da Vinci

"Innovation is saying no to a thousand things."

Steve Jobs

"The problem of the source of a star’s energy will be considered, by a process of exhaustion we are driven to conclude that the only possible source of a star’s energy is subatomic yet it must be confessed that the only hypothesis shows little disposition to accommodate itself to the detailed requirements of observation, and a critic might count up a large number of fatal objections."

Arthur Eddington

"So far as hypotheses are concerned, let no one expect anything certain from astronomy, which cannot furnish it, lest he accept as the truth ideas conceived for another purpose, and depart from this study a greater fool than when he entered it."

Nikolaus Kopernikus

"We know this by patient and long continued investigations - the surface of water is a LEVEL SURFACE. This is the key which is unlocking the minds of the people and letting in a flood of light upon the question of the shape of the earth. We know consequently that the surface of earth is a plane surface and that the earth itself can NOT be a globe."

John Hampden

"In the first place, God made idiots. That was for practice. Then he made school boards."

Mark Twain

"Actually neither this Galileo, nor his mentor Copernicus, had a shred of truly tangible and unequivocal evidence for their heliocentric belief – and well do historians, astronomers, and philosophers of science know it! As I recently found it succinctly expressed in a research paper “Since Galileo science has shed logical proofs in favour of plausibility. Indeed, by this “scientific method” of adding plausible explanations to plausible explanations astronomy has arrived at the present view of the cosmos. However, those who forget that “plausible” and “proven” are not synonyms inevitably will see their chickens come home to roost.”"

Walter van der Kamp

"The International Space Station is an orbital turkey....No important science has come out of it. I could almost say no science has come out of it. And I would go beyond that and say that the whole manned spaceflight program, which is so enormously expensive, has produced nothing of scientific value."

Steven Weinberg

"Anybody who has been seriously engaged in scientific work of any kind realizes that over the entrance to the gates of the temple of science are written the words: Ye must have faith. It is a quality which the scientist cannot dispense with."

Max Planck

"It is simply no longer possible to believe much of the clinical research that is published, or to rely on the judgment of trusted physicians or authoritative medical guidelines. I take no pleasure in this conclusion, which I reached slowly and reluctantly over my two decades as editor of The New England Journal of Medicine"

Marcia Angell

"The case against science is straightforward: much of the scientific literature, perhaps half, may simply be untrue. Afflicted by studies with small sample sizes, tiny effects, invalid exploratory analyses, and flagrant conflicts of interest, together with an obsession for pursuing fashionable trends of dubious importance, science has taken a turn towards darkness"

Richard Horton
