„Mir würde es gar nicht gefallen, zweimal zu sterben. Es ist so langweilig.“
Letzte Worte, 15. Februar 1988 - zu seiner Ehefrau, seiner Schwester und seiner Cousine, als er kurz aus einem durch Nierenversagen verursachten Koma erwachte.

Richard Phillips Feynman [ˈfaɪnmən] war ein US-amerikanischer Physiker und Nobelpreisträger des Jahres 1965.
Feynman gilt als einer der großen Physiker des 20. Jahrhunderts, der wesentliche Beiträge zum Verständnis der Quantenfeldtheorien geliefert hat. Zusammen mit Shin’ichirō Tomonaga und Julian Schwinger erhielt er 1965 den Nobelpreis für seine Arbeit zur Quantenelektrodynamik . Seine anschauliche Darstellung quantenfeldtheoretischer elementarer Wechselwirkungen durch Feynman-Diagramme ist heute ein De-facto-Standard.Für Feynman war es immer wichtig, die unanschaulichen Gesetzmäßigkeiten der Quantenphysik Laien und Studenten nahezubringen und verständlich zu machen. An Universitäten ist seine Vorlesungsreihe weit verbreitet. In Büchern wie QED: Die seltsame Theorie des Lichts und der Materie und Character of Physical Law wandte er sich an ein breiteres Publikum. Sein Charisma und die Fähigkeit, auf seine Zuhörerschaft einzugehen, ließen seine Vorlesungen und Vorträge legendär werden.
Seine unkonventionelle und nonkonformistische Art zeigte sich auch in seinen autobiographisch geprägten Büchern wie Sie belieben wohl zu scherzen, Mr. Feynman. Abenteuer eines neugierigen Physikers und Kümmert Sie, was andere Leute denken? In einem gleichnamigen Essay prägte er den Begriff der „Cargo-Kult-Wissenschaft“ für eine wissenschaftliche Disziplin, welche zwar der Form genügt, aber den Ansprüchen an den Inhalt nicht gerecht wird. Da der Begriff Cargo-Kult ursprünglich ein Verhaltensmuster von Ureinwohnern im Südpazifik beschrieb, zeigte dessen Verwendung in Bezug auf die Wissenschaft eine gewisse feinsinnige Respektlosigkeit.

Original englisch: "The trick is the idealizations. [...] This system is quite unlike the case of mathematics, in which everything can be defined, and then we do not know what we are talking about. In fact, the glory of mathematics is that we do not have to say what we are talking about. The glory is that the laws, the arguments, and the logic are independent of what 'it' is." - The Feynman Lectures on Physics: Quantum Mechanics. Addison-Wesley Pub. Co., 1965.

I too can see the stars on a desert night, and feel them. But do I see less or more? The vastness of the heavens stretches my imagination — stuck on this carousel my little eye can catch one-million-year-old light. A vast pattern — of which I am a part... What is the pattern, or the meaning, or the why? It does not do harm to the mystery to know a little about it. For far more marvelous is the truth than any artists of the past imagined! Why do the poets of the present not speak of it? What men are poets who can speak of Jupiter if he were a man, but if he is an immense spinning sphere of methane and ammonia must be silent?

I might think about it a little bit, and if I can't figure it out then I go on to something else. But I don't have to know an answer. I don't feel frightened by not knowing things, by being lost in the mysterious universe without having any purpose — which is the way it really is, as far as I can tell. Possibly. It doesn't frighten me.

Even if we knew every rule, however, we might not be able to understand why a particular move is made in the game, merely because it is too complicated and our minds are limited. If you play chess you must know that it is easy to learn all the rules, and yet it is often very hard to select the best move or to understand why a player moves as he does. So it is in nature, only much more so.

„Do not keep saying to yourself, if you can possibly avoid it, "But how can it be like that?"“

because you will get "down the drain", into a blind alley from which nobody has yet escaped. Nobody knows how it can be like that.

It is not odd at all. You only think you know, as a matter of fact. And most of your actions are based on incomplete knowledge and you really don't know what it is all about, or what the purpose of the world is, or know a great deal of other things. It is possible to live and not know.
