Physics is a Greek work and in a wider sense it means science of nature. All physical phenomena has to be reproducible is one of the vital elements in physics. It is important that all the theories be established by experiments or observations as it is the initial step towards the progress of any physical theory. The next step would comprise of structuring a model or theory in order to explain the experiment or the observations. Besides producing results of the said theory a model also has to make predictions. Predictions are important to clearly grasp the model of the physical process. To conclude the theory needs to be corroborated by the experimentations offered by the model.
