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:

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

    America is the most grandiose experiment the world has seen, but, I am afraid, it is not going to be a success.
    Sigmund Freud (1856–1939)

    I look on it as no trifling effort of female strength to withstand the artful and ardent solicitations of a man that is thoroughly master of our hearts. Should we in the conflict come off victorious, it hardly pays us for the pain we suffer from the experiment ... and I still persist in it that such a behaviour in any man I love would rob me of that most pleasing thought, namely, the obligation I have to him for not making such a trial.
    Sarah Fielding (1710–1768)
