The first amazing fact about gravitation is that the ratio of inertial mass to gravitational mass is constant wherever we have checked it. The second amazing thing about gravitation is how weak it is. Richard P. Feynman amazecheckconstant Change image and share on social
The ideas associated with the problems of the development of science, as far as I can see by looking around me, are not of the kind that everyone appreciates. Richard P. Feynman appreciatedevelopmentidea Change image and share on social
The extreme weakness of quantum gravitational effects now poses some philosophical problems; maybe nature is trying to tell us something new here: maybe we should not try to quantize gravity. Richard P. Feynman effectextremegravitational Change image and share on social
People often think I'm a faker, but I'm usually honest, in a certain way - in such a way that often nobody believes me! Richard P. Feynman believefakerhonest Change image and share on social
It is necessary to look at the results of observation objectively, because you, the experimenter, might like one result better than another. Richard P. Feynman experimenterobjectivelyobservation Change image and share on social
The philosophical question before us is, when we make an observation of our track in the past, does the result of our observation become real in the same sense that the final state would be defined if an outside observer were to make the observation?

Atoms are very special: they like certain particular partners, certain particular directions, and so on. It is the job of physics to analyze why each one wants what it wants. Richard P. Feynman analyzeatomdirection Change image and share on social
I don't know what's the matter with people: they don't learn by understanding; they learn by some other way - by rote, or something. Their knowledge is so fragile! Richard P. Feynman fragileknowledgelearn Change image and share on social
Because the theory of quantum mechanics could explain all of chemistry and the various properties of substances, it was a tremendous success. But still there was the problem of the interaction of light and matter. Richard P. Feynman chemistryexplaininteraction share on social
Each piece, or part, of the whole of nature is always merely an approximation to the complete truth, or the complete truth so far as we know it. In fact, everything we know is only some kind of approximation because we know that we do not know all the laws as yet. Richard P. Feynman approximationcompletefact share on social
