Experiment

In the scientific method, an experiment (Latin: ex-+-periri, "of (or from) trying"), is a set of actions concerning phenomena. The experiment is a cornerstone in the empirical approach to acquiring deeper knowledge about the physical world. Depending on the philosophical background an experiment can lead to the complete objective understanding of the physical world or just help improving subjective knowledge by fallibilism. In this case conducting research, means making a measurement and then writing some formulas and then it starts all over again.
