Citações Richard Feynman

„A filosofia da ciência é tão útil para o cientista quanto a ornitologia para os pássaros“

—  Richard Feynman

Richard Feynman, conforme relatado por Singh, Simon - Big Bang - Editora Record - Rio de Janeiro / São Paulo - 2006. ISBN: 85-01-07213-3 (pág. 459)

„Posso dizer seguramente que ninguém entende a física quântica.“

—  Richard Feynman, livro The Character of Physical Law

I think I can safely say that nobody understands quantum mechanics
The Character of Physical Law (1965) Ch. 6; MIT Press, 1967

„Os poetas reclamam que a ciência retira a beleza das estrelas. Mas eu posso vê-las de noite no deserto, e senti-las. Vejo menos ou mais?“

—  Richard Feynman, livro The Feynman Lectures on Physics

Poets say science takes away from the beauty of the stars — mere globs of gas atoms. Nothing is "mere". I too can see the stars on a desert night, and feel them. But do I see less or more?
The Feynman Lectures on Physics: Mainly Mechanics, Radiation, and Heat‎, de Richard Phillips Feynman, Robert B. Leighton, Matthew L. Sands - Publicado por Addison-Wesley, 1963

„A Física está para a Matemática como o sexo está para a masturbação.“

—  Richard Feynman

Physics is to mathematics what sex is to masturbation

„Se você acha que entendeu alguma coisa sobre mecânica quântica, então é porque você não entendeu nada.“

—  Richard Feynman

If you think you understand quantum mechanics, you don't understand quantum mechanics.

„A ideia é fornecer todas as informações, para que os outros possam julgar o valor de sua contribuição, e não apenas as informações que dirijam o julgamento para uma direção específica.“

„It is really quite impossible to say anything with absolute precision, unless that thing is so abstracted from the real world as to not represent any real thing.“

—  Richard Feynman

" New Textbooks for the "New" Mathematics http://calteches.library.caltech.edu/2362/1/feynman.pdf", Engineering and Science volume 28, number 6 (March 1965) p. 9-15 at p. 14
Paraphrased as "Precise language is not the problem. Clear language is the problem."
Contexto: The real problem in speech is not precise language. The problem is clear language. The desire is to have the idea clearly communicated to the other person. It is only necessary to be precise when there is some doubt as to the meaning of a phrase, and then the precision should be put in the place where the doubt exists. It is really quite impossible to say anything with absolute precision, unless that thing is so abstracted from the real world as to not represent any real thing.Pure mathematics is just such an abstraction from the real world, and pure mathematics does have a special precise language for dealing with its own special and technical subjects. But this precise language is not precise in any sense if you deal with real objects of the world, and it is only pedantic and quite confusing to use it unless there are some special subtleties which have to be carefully distinguished.

„Einstein was a giant. His head was in the clouds, but his feet were on the ground. But those of us who are not that tall have to choose!“

—  Richard Feynman

recalled by Carver Mead in Collective Electrodynamics: Quantum Foundations of Electromagnetism (2002), p. xix

„We are not to tell nature what she’s gotta be. … She's always got better imagination than we have.“

„The old problems, such as the relation of science and religion, are still with us, and I believe present as difficult dilemmas as ever, but they are not often publicly discussed because of the limitations of specialization.“

—  Richard Feynman

remarks (2 May 1956) at a Caltech YMCA lunch forum http://calteches.library.caltech.edu/49/2/Religion.htm
Contexto: In this age of specialization men who thoroughly know one field are often incompetent to discuss another. The great problems of the relations between one and another aspect of human activity have for this reason been discussed less and less in public. When we look at the past great debates on these subjects we feel jealous of those times, for we should have liked the excitement of such argument. The old problems, such as the relation of science and religion, are still with us, and I believe present as difficult dilemmas as ever, but they are not often publicly discussed because of the limitations of specialization.

„God was always invented to explain mystery. God is always invented to explain those things that you do not understand.“

—  Richard Feynman

interview published in Superstrings: A Theory of Everything? (1988) edited by Paul C. W. Davies and Julian R. Brown, p. 208-209
Contexto: God was always invented to explain mystery. God is always invented to explain those things that you do not understand. Now, when you finally discover how something works, you get some laws which you're taking away from God; you don't need him anymore. But you need him for the other mysteries. So therefore you leave him to create the universe because we haven't figured that out yet; you need him for understanding those things which you don't believe the laws will explain, such as consciousness, or why you only live to a certain length of time — life and death — stuff like that. God is always associated with those things that you do not understand. Therefore I don't think that the laws can be considered to be like God because they have been figured out.

„What I cannot create, I do not understand.Know how to solve every problem that has been solved.“

—  Richard Feynman

„I have a limited intelligence and I've used it in a particular direction.“

—  Richard Feynman, livro The Pleasure of Finding Things Out

" The Pleasure of Finding Things Out http://www.worldcat.org/wcpa/servlet/DCARead?standardNo=0738201081&standardNoType=1&excerpt=true", p. 2-3, transcript of BBC TV Horizon interview (1981): video http://www.youtube.com/watch?v=NEwUwWh5Xs4&t=2m53s
The Pleasure of Finding Things Out (1999)
Contexto: I've always been rather very one-sided about the science, and when I was younger, I concentrated almost all my effort on it. I didn't have time to learn, and I didn't have much patience for what's called the humanities; even though in the university there were humanities that you had to take, I tried my best to avoid somehow to learn anything and to work on it. It's only afterwards, when I've gotten older and more relaxed that I've spread out a little bit — I've learned to draw, and I read a little bit, but I'm really still a very one-sided person and don't know a great deal. I have a limited intelligence and I've used it in a particular direction.
