Famous Quotes & Sayings

Richard P. Feynman

I can live with doubt and uncertainty and not knowing. I think it is much more interesting to live not knowing than to have answers that might be wrong. If we will only allow that, as we progress, we remain unsure, we will leave opportunities for alternatives. We will not become enthusiastic for the fact, the knowledge, the absolute truth of the day, but remain always uncertain … In order to make progress, one must leave the door to the unknown ajar.

Richard P. Feynman

Unless a thing can be defined by measurement, it has no place in a theory. And since an accurate value of the momentum of a localized particle cannot be defined by measurement it therefore has no place in the theory.

Richard P. Feynman

It is odd, but on the infrequent occasions when I have been called upon in a formal place to play the bongo drums, the introducer never seems to find it necessary to mention that I also do theoretical physics.

Richard P. Feynman

Science is a way to teach how something gets to be known, what is not known, to what extent things are known (for nothing is known absolutely), how to handle doubt and uncertainty, what the rules of evidence are, how to think about things so that judgments can be made, how to distinguish truth from fraud, and from show.

Richard P. Feynman

Scientists are explorers. Philosophers are tourists.

Richard P. Feynman

The difficulty really is psychological and exists in the perpetual torment that results from your saying to yourself, "But how can it be like that?" which is a reflection of uncontrolled but utterly vain desire to see it in terms of something familiar. ... If you will simply admit that maybe [Nature] does behave like this, you will find her a delightful, entrancing thing. Do not keep saying to yourself, if you can possible avoid it, "But how can it be like that?" because you will get 'down the drain', into a blind alley from which nobody has escaped. Nobody knows how it can be like that.

Richard P. Feynman

If you thought that science was certain - well, that is just an error on your part.

Richard Dawkins

Cheetah genes cooperate with cheetah genes but not with camel genes, and vice versa. This is not because cheetah genes, even in the most poetic sense, see any virtue in the preservation of the cheetah species. They are not working to save the cheetah from extinction like some molecular World Wildlife Fund.

Richard Whately

To teach one who has no curiosity to learn, is to sow a field without ploughing it.

Jim Fox

Her perspective led me into self-discovery. I got to see the other side.

Walker Percy

Your discovery, as best as I can determine, is that there is an alternative which no one has hit upon. It is that one finding oneself in one of life's critical situations need not after all respond in one of the traditional ways. No. One may simply default. Pass. Do as one pleases, shrug, turn on one's heel and leave. Exit. Why after all need one act humanly?

Vincent Bugliosi

The conspiracy community regularly seizes on one slip of the tongue, misunderstanding, or slight discrepancy to defeat twenty pieces of solid evidence; accepts one witness of theirs, even if he or she is a provable nut, as being far more credible than ten normal witnesses on the other side; treats rumors, even questions, as the equivalent of proof; leaps from the most minuscule of discoveries to the grandest of conclusions; and insists that the failure to explain everything perfectly negates all that is explained.

Robertson Davies

Civilization rests on two things: the discovery that fermentation produces alcohol, and the voluntary ability to inhibit defecation. And I put it to you, where would this splendid civilization be without both?

William Least Heat-Moon

Without the errors, wrong turns and blind alleys, without the doubling back and misdirection and fumbling and chance discoveries, there was not one bit of joy in walking the labyrinth.

Wilhelm Reich

The discovery of orgone energy was made through consistent, thorough study of energy functions, first in the realm of the psyche, and later in the realm of biological functioning.

Winston Churchill

Our inheritance of well-founded, slowly conceived codes of honor, morals and manners, the passionate convictions which so many hundreds of millions share together of the principles of freedom and justice, are far more precious to us than anything which scientific discoveries could bestow.

Nate Berkus

You will enrich your life immeasurably if you approach it with a sense of wonder and discovery, and always challenge yourself to try new things.

Milan Kundera

Let us consider the critic, therefore, as a discoverer of discoveries.

Richard P. Feynman

In fact, the science of thermodynamics began with an analysis, by the great engineer Sadi Carnot, of the problem of how to build the best and most efficient engine, and this constitutes one of the few famous cases in which engineering has contributed to fundamental physical theory. Another example that comes to mind is the more recent analysis of information theory by Claude Shannon. These two analyses, incidentally, turn out to be closely related.

Richard Dawkins

The present Luddism over genetic engineering may die a natural death as the computer-illiterate generation is superseded.... I fear that, if the green movement's high-amplitude warnings over GMOs turn out to be empty, people will be dangerously disinclined to listen to other and more serious warnings.

James Grant

Progress is cumulative in science and engineering, but cyclical in finance.

Eric Hoffer

The most troublesome problem which confronts social engineering is how to provide for the untalented and, what is equally important, how to provide against them.

Kevin Mitnick

Social engineering is using manipulation, influence and deception to get a person, a trusted insider within an organization, to comply with a request, and the request is usually to release information or to perform some sort of action item that benefits that attacker.

Henry Petroski

Engineering is achieving function while avoiding failure.

David Pogue

What is innovation if not our ticket to every business interest in the world? Its the ticket to solving the worlds problems - the energy problems, the pollution problems, the global warming problems. If it isnt for science and engineering, how will we compete in the new world?

Arthur Ganson

I happen to love engineering. I love figuring things out in a spatial sense, that whole realm of working with mechanical parts, and the relationship of the parts, and things like ratios and the speeds of particular objects.

Bruce Dickinson

Don't ask me to put up a shelf, but I love engineering.
