Science uses different methods and techniques for the acquisition Science uses different methods and techniques for the acquisition and organization of knowledge about the and organization of knowledge about the structure of a set of objective facts and structure of a set of objective facts and accessible to several observers, as well as being based on a accessible to several observers, as well as being based on a criterion of truth and a permanent correction. criterion of truth and a permanent correction.
2. Introduction2. Introduction
The scientific method involves making a series of specific The scientific method involves making a series of specific processes that uses science to acquire processes that uses science to acquire knowledge. These specific processes are a set of rules or knowledge. These specific processes are a set of rules or steps, well-defined, which allow the steps, well-defined, which allow the end of its realization are obtained reliable results.end of its realization are obtained reliable results.

Theoretical method
In essence consists in drawing conclusions (deduction) of a principle or assumption.
Induction and deduction are used in the processes of the two methods. By thinking continuously induce and deduce.
This method was used by Einstein and Newton
