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

We are trying to prove ourselves wrong as quickly as possible, because only in that way can we find progress.

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.

Albert Einstein

Knowledge is limited; but imagination encircles the world.

Kate Winslet

'Harry Potter' really harnessed the imagination of so many young-adult minds, and it's the same with the 'Divergent' series.

Richard P. Feynman

What we need is imagination, but imagination in a terrible strait-jacket.

Rob Bell

Suffering, it turns out, demands profound imagination. A new future has to be conjured up because the old future isn't there anymore.

Richard Dawkins

Religions are not imaginative, not poetic, not soulful. On the contrary, they are parochial, small-minded, niggardly with the human imagination, precisely where science is generous.

Robin Wright

It's what still excites me most about acting: letting your imagination go places it's never been before. There's nothing better than that

Robert Nozick

The scientists often have more unfettered imaginations than current philosophers do. Relativity theory came as a complete surprise to philosophers, and so did quantum mechanics, and so did other things.

Robert Rauschenberg

I prefer images that are less specific, so there is room for everyone's imagination.

Wallace Stevens

Imagination applied to the whole world is vapid in comparison to imagination applied to a detail.

Robert Wiley

He's just fought his way, as he normally does through that, and his form in the WAFL has been exceptional, so it is a reward for his performances in the WAFL and (it's great for him) to just be able to get out there and play footy.

Harold Pinter

I think it's enough for me. I've found other forms now.

Ian Cameron

It is a less formal car, more streamlined, more about the individual.

The purpose of the Mobile Marketing Association is to safeguard this new form of spam that is literally in your face.

Tom Demko

We've been waiting for a game like this. That form has been missing from our play. We rebounded well, and our big guys played like big guys. We were able to run.

Dirk Kempthorne

It is my honor to serve with you, the people of Idaho. This great state, this forty-third star in the galaxy of states that form the greatest nation in the world.

David Sifry

Hyper-linking is a form of etiquette. It's a way of tapping someone on the shoulder with a sign of respect.

Todd Hollandsworth

I don't have a formula for it. You just prepare every day and try to be ready. We had lost three in a row, and I wanted to help out. I'm just glad the day went well for us.
