In theory, according to the University of Rochester:
- Observation and description of a phenomenon or group of phenomena.
- Formulation of an hypothesis to explain the phenomena. In physics, the hypothesis often takes the form of a causal mechanism or a mathematical relation.
- Use of the hypothesis to predict the existence of other phenomena, or to predict quantitatively the results of new observations.
- Performance of experimental tests of the predictions by several independent experimenters and properly performed experiments.
In practice, regarding a tuna sandwich. Observation/hypothesis. Test. Proof that applications are much more interesting than theory.
