Experiment

An experiment is a methodical procedure carried out with the goal of verifying, falsifying, or establishing the validity of a hypothesis. Experiments provide insight into cause-and-effect by demonstrating what outcome occurs when a particular factor is manipulated. Experiments vary greatly in their goal and scale, but always rely on repeatable procedure and logical analysis of the results. A child may carry out basic experiments to understand the nature of gravity, while teams of scientists may take years of systematic investigation to advance the understanding of a phenomenon. Experiments can vary from personal and informal (e.g. tasting a range of chocolates to find a favorite), to highly controlled (e.g. tests requiring complex apparatus overseen by many scientists that hope to discover information about subatomic particles). Uses of experiments vary considerably between the natural and social sciences.

Famous quotes containing the word experiment:

    What constitutes a real, live human being is more of a mystery than ever these days, and men—each one of whom is a valuable, unique experiment on the part of nature—are shot down wholesale.
    Hermann Hesse (1877–1962)

    Life is short, the art long, opportunity fleeting, experiment treacherous, judgment difficult.
    Hippocrates (c. 460–370 B.C.)

    It is proper to take alarm at the first experiment on our liberties.... Who does not see that the same authority which can establish Christianity, in exclusion of all other Religions, may establish with the same ease any particular sect of Christians, in exclusion of all other sects?
