scientific method

the way of approaching a problem by drawing up a hypothesis based on a series of observations, and then testing the hypothesis by means of experiments designed in such a way as to support or invalidate the hypothesis. On the basis of the experimental evidence a theory is proposed to account for the initial observations. If subsequently the theory is found to be wanting in some respect, new hypotheses are sought and tested experimentally, so the process is a successive refinement which in science never leads to an absolute truth, but to a more reliable knowledge.
