   Scientific Method: The scientific method involves four steps geared towards finding truth:
1. Observation and description of a phenomenon or group of phenomena.  
2. Formulation of an hypothesis to explain the phenomena - usually in the form of a causal mechanism or a mathematical relation.
3. Use of the hypothesis to quantitatively predict the results of new observations (or the existence of other related phenomena).
4. Performance of experimental tests of the predictions by several independent experimenters and properly performed experiments.
