What is science? If you are looking for definitions in the literature, you can find that most definitions of Science share one statement: science consists of accumulating knowledge (Klemke et al. 1988, Ziman 1988, 2001). Scientists ask why the world is like this and not in a different way. This results in observing nature in a particular condition and documenting the results. Furthermore, there is a distinction between pure science, which is the field of knowledge, and applied science, which is the use of knowledge to create and manipulate on behalf of human needs (Klemke et al. 1988). Scientific knowledge is always a conjectural hypothesis. knowledge based on hypotheses (Popper 1988). These are continually compared and contrasted with reality in order to be "improved" and brought closer to it (Popper 1988). Therefore the tests do not "prove" the truth, but only the correctness of the procedures followed. Again, Popper (1988) demonstrated that only those propositions that research could prove false should be considered scientific (falsification principle). Furthermore, Kuhn (1988) noted that a scientific paradigm, consisting of shared views, general ideas, or beliefs that a group of people may have for understanding theories and theory of reality, applies until they are invalidated by exceptions and contradictions that they can no longer resolve.In my opinion, the process of gathering knowledge must begin with pure science. Ecology, for example, first describes the patterns observable in nature. Without this, it would not be possible to develop questions and ideas about how the world works. But what differentiates science from non-science? Theories and Hypotheses To answer this question, we need to understand how to gather scientific knowledge...... middle of paper ......from a research question from an observation of a natural pattern of species richness along the l intertidal elevation. The pattern I observed was not consistent with the theories I had learned from my teachers or supervisors. The researchers around me preferred some generally accepted constructions of models of species richness patterns, and thanks to the use of a correct scientific method that provided me with the basis to support my theories, I was able to defend them and convince the my supervisor to leave me continues to work on it. Science is not just knowledge; it is also the method you use to prove that the collected knowledge really exists. This leads me to answer that the difference between science and non-science is making sure that what you observe or the knowledge you gather comes from an objective method. To make sure it's true.
