"All scientific work is incomplete – whether it be observational or experimental. All scientific work is liable to be upset or modified by advancing knowledge. That does not confer upon us a freedom to ignore the knowledge we already have, or to postpone the action that it appears to demand at a given time."
The Settlement ... is an experimental effort to aid in the solution of the social and industrial problems which are engendered by the modern conditions of life in a great city. It insists that these problems are not confined to any one portion of the city. It is an attempt to relieve, at the same time, the overaccumulation at one end of society and the destitution at the other ...jane addams
The idea of a God we infer from our experimental dependence on something superior to ourselves in wisdom, power and goodness, which we call God; our senses discover to us the works of God which we call nature, and which is a manifest demonstration of his invisible essence. Thus it is from the works of nature that we deduce the knowledge of a God, and not because we have, or can have any immediate knowledge of, or revelation from him.ethan allen
Grosseteste's contribution was to emphasize the importance of falsification in the search for true causes and to develop the method of verification and falsification into a systematic method of experimental procedure.
The progress of knowledge is very irregular, somewhat resembling the movements of an army, of which some battalions are in vigorous health, while others are sickly or overburdened with baggage. The experimental marches on at a good pace; the observational proceeds but slowly; the speculative is left far in the rear.
You should look at all the experimental information at hand, not only the most relevant, and be prepared to make conjectures if that helps.
With Heisenberg's uncertainty principle, the fundamental role of experimental errors became a basic feature of physics.léon brillouin
Both the uncertainty principle and the negentropy principle of information make Laplace's scheme [of exact determinism] completely unrealistic. The problem is an artificial one; it belongs to imaginative poetry, not to experimental science.léon brillouin
The trouble is that you won't get the scientists to agree on a course of action. It is almost instinctive in science to accept contrary views, because disagreeing gives you guidance to experimental tests of ideas — your own and those offered by others….frederick seitz
Every sentence in order to have definite scientific meaning must be practically or at least theoretically verifiable as either true or false upon the basis of experimental measurements either practically or theoretically obtainable by carrying out a definite and previously specified operation in the future. The meaning of such a sentence is the method of its verification.walter a. shewhart
The mathematical forms of order which the mind of a physicist manipulates coincides "miraculously" with experimental measurements.marie-louise von franz
If physics is too difficult for the physicists, the nonphysicist may wonder whether he should try at all to grasp its complexities and ambiguities. It is undeniably an effort, but probably one worth making, for the basic questions are important and the new experimental results are often fascinating. And if the layman runs into serious perplexities, he can be consoled with the thought that the points which baffle him are more than likely the ones for which the professionals have not found satisfactory answers.edward condon
[O]pen platforms and experimental amateurs ... eventually beat out the spendy, slick pros. ... Relying on incumbents to produce your revolutions is not a good strategy. They're apt to take all the stuff that makes their products great and try to use technology to charge you extra for it, or prohibit it altogether.cory doctorow
To get anywhere, one must choose one’s mistakes, I chose experimental acts. (1963)asger jorn
We shall see that the mathematical treatment of the subject [of electricity] has been greatly developed by writers who express themselves in terms of the 'Two Fluids' theory. Their results, however, have been deduced entirely from data which can be proved by experiment, and which must therefore be true, whether we adopt the theory of two fluids or not. The experimental verification of the mathematical results therefore is no evidence for or against the peculiar doctrines of this theory.james clerk maxwell
One truth we have been able to count on concerning scientific persuit over the centuries has been that only testable theories survive the intense scrutiny of experimental science.john moffat
His reluctance to pay for elaborate or expensive equipment, perhaps the result of an impoverished childhood, had established the legendary "sealing wax-and-string" tradition of the Cavendish , where everyday materials were ingeniously used to make and patch up experimental equipment, with sealing wax proving particularly useful for vacuum seals.j. j. thomson
A theorist today is hardly considered respectable if he or she has not introduced at least one new particle for which there is no experimental evidence.steven weinberg
Grosseteste's experimental method was quite different from a method of controlled experiment. Grosseteste made no use of such a method in his writings, deriving his conclusions on the basis of a mix of considerations, appealing to authority and everyday observation (the Latin “experimentum”). He made use of thought experiments and certain metaphysical assumptions, such as the assumption of a principle of “least action.”
Without once compromising his artistic integrity, Fellini imagined a body of work -- as opposed to a suite of spin-offs, remakes, potboilers and so on -- where each production can be ranked as among the finest of experimental films ever to reach and influence an international public. There is a breathtaking scope to that achievement and great courage in the process: surmounting unbelievable resistance from producers, enemies of all kinds and jealous colleagues, career reversals, and poor health, Fellini held true to his own vision of cinema forged in the smithy of his soul.
Numerical analysis is very much an experimental science.
The overwhelming majority of theories are rejected because they contain bad explanations, not because they fail experimental tests.
Thinking is an experimental dealing with small quantities of energy, just as a general moves miniature figures over a map before setting his troops in action.
Only a few years ago one could observe, at least among German psychologists, a quite pessimistic mood. After the initial successes of experimental psychology in its early stages, it seemed to become clearer and clearer that it would remain impossible for experimental method to press on beyond the psychology of perception and memory to such vital problems as those with which psychoanalysis was concerned. Weighty 'philosophical' and 'methodological' considerations seemed to make such an undertaking a priori impossible.
experimental physics was particularly interested in the processes taking place inside the atom, and in this field the classical mechanics was failing conspicuously and completely. Perhaps its most spectacular failure was with the fundamental problem with the structure of the atom.
