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.

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.

Richard D. James

A lot of composers before me have been on this mission to change the world by getting off equal temperament, and I'm definitely one of those.

Rob Sheffield

'I'll Tumble 4 Ya' has to be one of the most ridiculous hit singles that any international superstars have given the world.

Richard Dawkins

Science is the disinterested search for the objective truth about the material world.

Richard Wright

Anything seemed possible, likely, feasible, because I wanted everything to be possible... Because I had no power to make things happen outside of me in the objective world, I made things happen within. Because my environment was bare and bleak, I endowed it with unlimited potentialities, redeemed it for the sake of my own hungry and cloudy yearning.

Richelle Mead

I'll find you. There is no place in this world you can hide from me. I'm watching. Love, Dimitri

Richelle Mead

This was the kind of dress that changed the world. The kind of dress that started religions.

Russell Brand

The only Revolution that can really change the world is the one in your own consciousness, and mine has already begun.

Ronda Rousey

I'm the most dangerous unarmed women in the world, I've prepared my entire life to be that way.

Ronda Rousey

It's your purpose to leave the world better than how you found it.
