Scientific Knowledge Quotes

This freedom of communication is indispensable for the development and extension of scientific knowledge, a consideration of much practical import. In the first instance it must be guaranteed by law. But laws alone cannot secure freedom of expression; in order that every man may present his views without penalty there must be a spirit of tolerance in the entire population. Such an ideal of external liberty can never be fully attained but must be sought unremittingly if scientific thought, and philosophical and creative thinking in general, are to be advanced as far as possible.

When a scientist doesn't know the answer to a problem, he is ignorant. When he has a hunch as to what the result is, he is uncertain. And when he is pretty darn sure of what the result is going to be, he is still in some doubt. We have found it of paramount importance that in order to progress we must recognize our ignorance and leave room for doubt. Scientific knowledge is a body of statements of varying degrees of certainty - some most unsure, some nearly sure, but none absolutely certain.

We need less memorization - I never memorized the periodic table of the elements - I've never used it, and I'm a physicist! I can look it up.

Science is a wonderful thing if one does not have to earn one's living at it.

Laws alone cannot secure freedom of expression; in order that every man present his views without penalty there must be a spirit of tolerance in the entire population.

I would love to be remembered for ridding the world of disease, but my knowledge of science comes from episodes of 'Nova' and shows on the Discovery Channel. I don't think a superficial understanding of shark behavior and black holes can help cure diseases.

Science is the most reliable guide in life.

My dream was to be a 'scientist' even before I knew what a scientist did.

Science is knowledge which we understand so well that we can teach it to a computer; and if we don't fully understand something, it is an art to deal with it.

When we explore other planets, we learn a lot about our own.

Fortunately, nature is as generous with its problems as Nobel with his fortune. The more we know, the more aware we are of what we know not.

Languages are the keys of science.

Science is really about describing the way the universe works in one aspect or another in all branches of science—how a life-form works, how this works, how that works. ... You have to have a natural curiosity for that.

In physical science a first essential step in the direction of learning any subject is to find principles of numerical reckoning and practicable methods for measuring some quality connected with it. I often say that when you can measure what you are speaking about, and express it in numbers, you know something about it; but when you cannot measure it, when you cannot express it in numbers, your knowledge is of a meagre and unsatisfactory kind; it may be the beginning of knowledge, but you have scarcely in your thoughts advanced to the stage of science, whatever the matter may be.

It is wrong to think that the task of physics is to find out how Nature is. Physics concerns what we say about Nature.

The liberating force of scientific knowledge is objectively expressed in the great achievements of technology. Whoever possesses technology has power of the earth and men. As a result of this, hitherto unknown forms of inequality have arisen between those who possess knowledge and those who are simple users of technology.

I think it was this curiosity about the natural world which awoke my early interest in science.

Science is the ultimate tool to reveal the laws of nature, and the one word written on its banner is Truth.

Common sense is not something rigid and stationary, but is in continuous transformation, becoming enriched with scientific notions and philosophical opinions that have entered into common circulation. 'Common sense' is the folklore of philosophy and always stands midway between folklore proper (folklore as it is normally understood) and the philosophy, science, and economics of the scientists. Common sense creates the folklore of the future, a relatively rigidified phase of popular knowledge in a given time and place.

Having played many roles of scientific intellect I do have an empathy for that world. It's been hard on me because flying the Enterprise for seven years in Star Trek and sitting in Cerebro in X-men has led people to believe that I know what I'm talking about. But I'm still trying to work out how to operate the air conditioning unit on my car.

Science rules!
