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.

Richard P. Feynman

In fact, the science of thermodynamics began with an analysis, by the great engineer Sadi Carnot, of the problem of how to build the best and most efficient engine, and this constitutes one of the few famous cases in which engineering has contributed to fundamental physical theory. Another example that comes to mind is the more recent analysis of information theory by Claude Shannon. These two analyses, incidentally, turn out to be closely related.

Richard Dawkins

The present Luddism over genetic engineering may die a natural death as the computer-illiterate generation is superseded.... I fear that, if the green movement's high-amplitude warnings over GMOs turn out to be empty, people will be dangerously disinclined to listen to other and more serious warnings.

James Grant

Progress is cumulative in science and engineering, but cyclical in finance.

Eric Hoffer

The most troublesome problem which confronts social engineering is how to provide for the untalented and, what is equally important, how to provide against them.

Kevin Mitnick

Social engineering is using manipulation, influence and deception to get a person, a trusted insider within an organization, to comply with a request, and the request is usually to release information or to perform some sort of action item that benefits that attacker.

Henry Petroski

Engineering is achieving function while avoiding failure.

David Pogue

What is innovation if not our ticket to every business interest in the world? Its the ticket to solving the worlds problems - the energy problems, the pollution problems, the global warming problems. If it isnt for science and engineering, how will we compete in the new world?

Arthur Ganson

I happen to love engineering. I love figuring things out in a spatial sense, that whole realm of working with mechanical parts, and the relationship of the parts, and things like ratios and the speeds of particular objects.

Bruce Dickinson

Don't ask me to put up a shelf, but I love engineering.

Joe Monahan

He could influence the outcome of the race. If he does have any ideas he wants to see advanced, this is the time to do it.

Jon Hurst

There are still a ton of mom-and-pops out there that come up with new ideas and new niches.

Monica Procar

We make a lot of what is in here ourselves. We make the wreaths and the swags and whatever ideas that we can come up with.

Isadora Duncan

ideas and words that do not make any sense.

Robert Collier

All riches have their origin in mind. Wealth is in ideas - not money.

Rob Reiner

Harry [Shearer] and I had an idea to do a movie about rock 'n' roll from the roadies' perspective, from backstage. Then Meat Loaf came out with a movie called Roadie and we thought, "Oh, we can't do that now." So we kind of discarded the idea.

Rob Reiner

The idea of playing a part where I get to wear a completely undetectable hairpiece... you can't walk away from that.

Rob Sheffield

We all get as miserable as Erika M. Andersen sometimes, but we rarely approach her musical-ideas-per-miserable-minute ratio.

Rob Brown

When you work on a computer in the studio, it's almost like fossilizing on the spot, you know, the idea of getting solidified on the spot, like a snowflake might create branches by accumulation.
