STRATEGY OF DATA-BASED INVESTIGATION

The diagrammed investigation begins with a hypothesis (model), which might come from inspiration or from an analysis of existing information. To test this hypothesis, the investigator designs some experiments, performs 

Many physical and chemical principles have been developed in this way. including the law of definite proportions, the periodic table of the elements, the structures of molecules, and the currently favored mechanisms of many chemical reactions. High-energy physics has progressed impressively through such iterations on many projects.
