Halál dátuma: 15. február 1988
Más nevek: Richard Feynman Philips, Richard Phillips Feynman, Ричард Филлипс Фейнман

Richard Phillips Feynman Nobel-díjas amerikai elméleti fizikus, tudománynépszerűsítő, sokak szerint a 20. század, de különösen a II. világháború utáni időszak legnagyobb hatású elméje. Mind a tudományos kutatás, mind pedig a tudományos ismeretterjesztés területén kiemelkedőt alkotott, így több generáció számára jelentett és jelent ma is inspirációt. A nemzetközi szkeptikus mozgalomban is úttörőként emlegetik, aki előszeretettel leplezett le csalásokat és hívta fel a figyelmet arra, hogy megfelelően kivitelezett trükkökkel a legjobb szellemi képességű embereket is be lehet csapni. Híres volt játékosságáról, de a komolyság és az őszinteség is fontos részét képezte személyiségének, élvezte az életet , de köztudottan irtózott a formalitásoktól.

Előadásai és interjúi, valamint a róla szóló életrajzi írások a mai napig is népszerűek, számos általa írt vagy róla szóló könyv kapható magyar nyelven is. Wikipedia

„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
Kontextus: 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, könyv 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)
Kontextus: 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.

„The real problem in speech is not precise language. The problem is clear language.“

—  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."
Kontextus: 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.
