The Quantum Universe has a quotation from me in every chapter - but it's a damn good book anyway. Richard P. Feynman More Quotes by Richard P. Feynman More Quotes From Richard P. Feynman We absolutely must leave room for doubt or there is no progress and there is no learning. There is no learning without having to pose a question. And a question requires doubt. People search for certainty. But there is no certainty. People are terrified — how can you live and not know? 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. Richard P. Feynman incomplete-knowledgepeoplethinking It is important to realize that in physics today, we have no knowledge of what energy is Richard P. Feynman importantenergytoday What did you ASK at school today? Richard P. Feynman educationalteachingschool All the time you're saying to yourself, 'I could do that, but I won't,'--which is just another way of saying that you can't. Richard P. Feynman another-wayway Poets say science takes away from the beauty of the stars - mere globs of gas atoms. I, too, can see the stars on a desert night, and feel them. But do I see less or more? Richard P. Feynman starsnightscience I wonder why. I wonder why. I wonder why I wonder. Richard P. Feynman wonder There is no authority who decides what is a good idea. Richard P. Feynman physicsauthorityideas The first principle is that you must not fool yourself—and you are the easiest person to fool. So you have to be very careful about that. After you’ve not fooled yourself, it’s easy not to fool other scientists. You just have to be honest in a conventional way after that. Richard P. Feynman foolprinciplesway There is no harm in doubt and skepticism, for it is through these that new discoveries are made. Richard P. Feynman doubtdiscoveryscience Nature uses only the longest threads to weave her patterns, so that each small piece of her fabric reveals the organization of the entire tapestry. Richard P. Feynman natureupliftingwisdom In any organization there ought to be the possibility of discussion... fence sitting is an art, and it's difficult, and it's important to do, rather than to go headlong in one direction or the other. It's just better to have action, isn't it than to sit on the fence? Not if you're not sure which way to go, it isn't. Richard P. Feynman one-directionartthinking To not know math is a severe limitation to understanding the world. Richard P. Feynman understandingbeermath Science alone of all the subjects contains within itself the lesson of the danger of belief in the infallibility of the greatest teachers of the preceding generation. Richard P. Feynman generationsfaithteacher Do not read so much, look about you and think of what you see there. Richard P. Feynman looksthinking I love to think. I once considered taking drugs as an attempt to better understand an altered state of mind; however, I decided not to. I didn't want to chance ruining the machine. Richard P. Feynman drugmindthinking For those who want some proof that physicists are human, the proof is in the idiocy of all the different units which they use for measuring energy. Richard P. Feynman differentusescience It is simple, therefore it is beautiful Richard P. Feynman simplebeautiful What I cannot create, I do not understand. Richard P. Feynman learningeducationinspiring Have no respect whatsoever for authority; forget who said it and instead look what he starts with, where he ends up, and ask yourself, "Is it reasonable?"
