The human and natural sciences are considered knowledge by many in the world because their arguments have convinced people in one way or another. While the natural sciences focus on influencing beliefs by showing duplicable evidence through strict, standardized methodology, the humanities focus on explaining the way things are and how they came to be using the logic, reason and understanding of human behavior. revolution of the 1500s, the Western world has become accustomed to accepting knowledge that relies on the scientific method, a method that has been standardized around the world to achieve the most accurate results. This method allows one to believe that the results obtained from an experiment conducted according to the scientific method have been properly and rigorously tested and must therefore be closest to the truth. This method also allows any experiment to be reproduced with the same results, which further strengthens the credibility and position of natural sciences in the world. Another aspect that allows the reliability of natural sciences is that of current paradigmatic boxes, which distort the truth to eliminate anomalies. This affects the outcome of the experiments because hypotheses will be made to create results that fit the framework of the paradigm. The scientific method varies slightly, as there is no exact universal method, but there is a basic six-step form that is widely accepted. . This form has been embellished and improved over time; however, the first established form was invented by Ibn al-Haythem, a Muslim physicist, in his Book of Optics. It is thus:1. Explicit statement of a problem, linked to observation and proof by experiment2. Testing and/or critiquing a hypothesis...... middle of article ...... results that attempt to be unbiased, and the paradigm box ensures that the experiments conducted fit the thought pattern of the majority of people. Human science uses logic and reason to explain how things are that appeal to a person's thought and understanding. Both are justifiable in their own circumstances and use ways of knowing that directly affect their methodology. Works Cited Popper, KR (1959). The logic of scientific discovery.
