What methodology do scientists use?

Research implies on the method of understanding how things work. Experiments are one of the most important utilities of understanding the subject. Experiments also help in proving a fact. Experiments can be compared to evidences in court cases. Until and unless you have enough evidence to support that a particular person is a criminal, nobody would trust you. Similarly, experiments serve as evidences for scientists to prove their views. Sometimes there are no possible experiments to prove a view. During such cases. mathematics is usually used, and the validity is proved by the fact that any further experiments taking into consideration this mathematical outcome turns out to be true. For e.g. the Avogadro's number as 6.023 x 1023. This cannot be proved, since one cannot literally count molecules and ascertain the value. But when later experiments are conducted taking Avogadro's Number as 6.023 x 1023, the experiment is correct. Most of the theories however can be explained by experiments.
