Famous Quotes & Sayings

Bertrand Russell

The pursuit of knowledge is, I think, mainly actuated by love of power

Richard P. Feynman

A very great deal more truth can become known than can be proven.

William Whewell

According to the technical language of old writers, a thing and its qualities are described as subject and attributes; and thus a man's faculties and acts are attributes of which he is the subject. The mind is the subject in which ideas inhere. Moreover, the man's faculties and acts are employed upon external objects; and from objects all his sensations arise. Hence the part of a man's knowledge which belongs to his own mind, is subjective: that which flows in upon him from the world external to him, is objective.

Samuel Smiles

Knowledge conquered by labor becomes a possession -a property entirely our own.

Richard Francis Burton

Indeed he knows not how to know who knows not also how to un-know.

Richard P. Feynman

If we will only allow that, as we progress, we remain unsure, we will leave opportunities for alternatives.

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

Progress in science comes when experiments contradict theory.

Richard P. Feynman

The game I play is a very interesting one. It's imagination in a straightjacket, which is this: that it has to agree with the known laws of physics. ... It requires imagination to think of what's possible, and then it requires an analysis back, checking to see whether it fits, whether its allowed, according to what's known, okay?

Richard P. Feynman

You can know the name of a bird in all the languages of the world, but when you're finished, you'll know absolutely nothing whatever about the bird... So let's look at the bird and see what it's doing -- that's what counts.

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.

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.

Originality implies a return to the origins, original is returning to the simplicity of the first solutions.

Richard P. Feynman

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

Richard P. Feynman

Nature's imagination far surpasses our own.

Richard P. Feynman

Our imagination is stretched to the utmost, not, as in fiction, to imagine things which are not really there, but just to comprehend those things which are there.

Roald Dahl

There is no life I know to compare with pure imagination. Living there, you'll be free if you truly wish to be.
