Experiment is the sole judge of the validity of any idea. Richard P. Feynman More Quotes by Richard P. Feynman More Quotes From Richard P. Feynman I would rather have questions that can't be answered than answers that can't be questioned. Richard P. Feynman answers Fall in love with some activity, and do it! Nobody ever figures out what life is all about, and it doesn't matter. Explore the world. Nearly everything is really interesting if you go into it deeply enough. Work as hard and as much as you want to on the things you like to do the best. Don't think about what you want to be, but what you want to do. Keep up some kind of a minimum with other things so that society doesn't stop you from doing anything at all. Richard P. Feynman falling-in-love interesting thinking Study hard what interests you the most in the most undisciplined, irreverent and original manner possible. Richard P.

Feynman education motivational inspirational The truth always turns out to be simpler than you thought. Richard P. Feynman simplicity truth science It doesn't matter how beautiful your theory is, it doesn't matter how smart you are. If it doesn't agree with experiment, it's wrong. Richard P. Feynman smart beautiful science Our responsibility is to do what we can, learn what we can, improve the solutions, and pass them on. Richard P. Feynman human-race unreasonable responsibility If you think you understand quantum mechanics, you don't understand quantum mechanics. Richard P. Feynman mechanic quantum thinking Physics is like sex: sure, it may give some practical results, but that's not why we do it. Richard P. Feynman learning science sex I think it's much more interesting to live not knowing than to have answers which might be wrong. I have approximate answers, and possible beliefs, and different degrees of uncertainty about different things, but I am not absolutely sure of anything. There are many things I don't know anything about, such as whether it means anything to ask "Why are we here?" 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. Richard P.

Feynman students years firsts Science is the belief in the ignorance of experts. Richard P. Feynman ignorance science thinking No government has the right to decide on the truth of scientific principles, nor to prescribe in any way the character of the questions investigated. Neither may a government determine the aesthetic value of artistic creations, nor limit the forms of literacy or artistic expression. Nor should it pronounce on the validity of economic, historic, religious, or philosophical doctrines. Instead it has a duty to its citizens to maintain the freedom, to let those citizens contribute to the further adventure and the development of the human race. Richard P. Feynman philosophical religious character The thing that doesn't fit is the thing that is most interesting. Richard P.

And a question requires doubt. People search for certainty. But there is no certainty. Richard P. Feynman progress doubt people To those who do not know mathematics it is difficult to get across a real feeling as to the beauty, the deepest beauty, of nature ... If you want to learn about nature, to appreciate nature, it is necessary to understand the language that she speaks in. Richard P. Feynman learning nature real My rule is, when you are unhappy, think about it. But when you're happy, don't. Why spoil it? You're probably happy for some ridiculous reason and you'd just spoil it to know it. Richard P. Feynman ridiculous unhappy thinking Scientists are explorers. Philosophers are tourists. Richard P.
