Famous Quotes & Sayings

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.

Joe Miller

He did a good job running the offense. Howard had a few transition baskets in the run (to erase the 16-point deficit).

Roger Ailes

I grew up in the era when Dan Rather hated Richard Nixon. He was a newsman, but you knew what his opinion was.

Henry Cavill

No matter what era we're in, we need hope.

David Boyer

Then it erased it and wrote it again, and did it all day. People loved it.

Freda Adler

The passionate controversies of one era are viewed as sterile preoccupations by another, for knowledge alters what we seek as well as what we find.

Charlton Heston

The big studio era is from the coming of sound until 1950, until I came in I came in at a crux in film, which was the end of the studio era and the rise of filmmaking.

Brian Eno

Nothing so dates an era as its conception of the future.

Brian Greene

We are living through a remarkably privileged era, when certain deep truths about the cosmos are still within reach of the human spirit of exploration.

Harry Knox

Erasing persecution of gays from the history of the Holocaust repeats the tragic silence of most Germans in the Nazi years.

Linus Pauling

Life is a relationship among molecules and not a property of any molecule.

Otto Wallach

As soon as chemists have a definite conception of the internal structure of the molecule of an organic compound, they are able to tackle the task of producing these substances by artificial methods, i.e. by synthesis, as we call it.

Dorothy Hodgkin

The detailed geometry of the coenzyme molecule as a whole is fascinating in its complexity.

George Wald

I have lived much of my life among molecules. They are good company.

Jean-Marie Lehn

Darwinan evolution is limited to the biological aspect but before that happened the molecules themselves had to evolve to enable this further (biological) evolution.
