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.

Wyndham Lewis

The Relativity theory, the copernican upheaval, or any great scientific convulsion, leaves a new landscape. There is a period of stunned dreariness; then people begin, antlike, the building of a new human world. They soon forget the last disturbance. But from these shocks they derive a slightly augmented vocabulary, a new blind spot in their vision, a few new blepharospasms or tics, and perhaps a revised method of computing time.

Daniel Gilbert

Because your brain uses information from the areas around the blind spot to make a reasonable guess about what the blind spot would see if only it weren't blind, and then your brain fills in the scene with this information. That's right, it invents things, creates things, makes stuff up! It doesn't consult you about this, doesn't seek your approval. It just makes its best guess about the nature of the missing information and proceeds to fill in the scene...

Michael Crichton

Considering that we live in an era of evolutionary everything---evolutionary biology, evolutionary medicine, evolutionary ecology, evolutionary psychology, evolutionary economics, evolutionary computing---it was surprising how rarely people thought in evolutionary terms. It was a human blind spot. We look at the world around us as a snapshot when it was really a movie, constantly changing.

Hunter S. Thompson

Some people will say that words like scum and rotten are wrong for Objective Journalism -- which is true, but they miss the point. It was the built-in blind spots of the Objective rules and dogma that allowed Nixon to slither into the White House in the first place.

Chris Byrd

To fight three times in three years is crazy. It has been disappointing to the point of sometimes you get frustrated and really just want to retire. I have been to that point, but God is faithful and I just keep plugging along. I just have to remain patient and fights will happen, but it has been disappointing.

Walter Scott

To every lovely lady bright, I wish a gallant faithful knight; To every faithful lover, too, I wish a trusting lady true.

Jacqueline Onassis

I do not think that there are any men who are faithful to their wives.

William Ellery Channing

Let us aspire towards this living confidence, that it is the will of God to unfold and exalt without end the spirit that entrusts itself to Him in well-doing as to a faithful Creator.

Vance Havner

Faith has no value of its own, it has value only as it connects us with Him. It is a trick of Satan to get us occupied with examining our faith instead of resting in the Faithful One.

Winston Churchill

The person must be blind, indeed, who can not see, that here on earth a great project, a great plan, is executed, may work on the realization of which we participate as faithful servants.

Winston Churchill

The one who cannot see that on Earth a big endeavor is taking place, an important plan, on which realization we are allowed to collaborate as faithful servants, certainly has to be blind.

Marcel Proust

We can only be faithful to what we remember, and we remember only what we have known.

Norodom Sihamoni

In all my life and in the future, I will always be a faithful and loyal servant to all of my compatriots.
