…test the hypotheses by appropriate experiments. The most original and inquiring mind is severely limited without the proper tools to conduct an investigation; conversely, the most-sophisticated technological equipment cannot of itself yield insights into any scientific process.

- In cluster: Methods of study
Clusters can be studied by experiment, by theoretical analysis, and by simulation with computer-generated models. For several reasons they cannot be studied in the same manner as bulk matter. First, if individual clusters are allowed to coalesce into a mass, they will actually turn into bulk matter, so they must…

A controlled experiment involves taking two closely related situations or groups, subjecting one of them to a specific stimulus, and comparing the subsequent characteristics of both. In the past, so-called experiments by judicial, penal, and reformatory institutions were not really controlled or even…

…of measurement is the controlled experiment. Carefully selected samples of members of the intended audiences can be subjected to the propaganda while equivalent samples are not. Or the same message, clothed in different symbols—different mixes of sober argument and “casual” humour, different proportions of patriotic, ethnic, and religious rationalizations, different…

…of medical progress; the new experimental method by which the results were secured was as noteworthy as the work itself. Following the method described by the philosopher Francis Bacon, he drew the truth from experience and not from authority.

The foregoing discussion should have made clear that progress in physics, as in the other sciences, arises from a close interplay of experiment and theory. In a well-established field like classical mechanics, it may appear that experiment is almost unnecessary and all…

…the first men to perform experiments on living animals. Both Müller and Bernard, however, recognized that the results of observations and experiments must be incorporated into a body of scientific knowledge, and that the theories of natural philosophers must be tested by experimentation. Many important ideas in physiology were investigated…

- In sociology: Experiments
Experimental methods, once limited to the domain of psychologists and considered inapplicable to social research, were eventually applied to the study of groups. By the 1930s, social psychologists Kurt Lewin, Muzafer Sherif, and their colleagues had begun conducting experiments on social interaction. Sociologists soon…

The experimental dimension had wide applications following Harvey’s demonstration of the circulation of blood. From then on, medical physiology developed rapidly; notable texts appeared, such as Albrecht von Haller’s eight-volume work Elementa Physiologiae Corporis Humani (Elements of Human Physiology), which had a medical emphasis. Toward the…

Experiment, that is, altering natural conditions in order to throw light on the hidden properties and activities of objects, was unnatural and could not, therefore, be expected to reveal the essence of things. Experiment was thus not essential to Greek science.

…a mathematical one in which experimentation became a recognized method for discovering the facts of nature. Finally, his discoveries with the telescope revolutionized astronomy and paved the way for the acceptance of the Copernican heliocentric system, but his advocacy of that system eventually resulted in an Inquisition process against him.

Experimentation either verifies or falsifies a theory by testing its empirical consequences. For Grosseteste, the study of nature is impossible without mathematics. He cultivated the science of optics (perspectiva), which measures the behaviour of light by mathematical means. His studies of the rainbow and comets…
