What Is Science?

Definition of science

The Spanish Royal Academy defines science as the “body of knowledge obtained through observation and reasoning, systematically structured and which general principles and laws are deduced.”

The word comes from scientia, or “knowledge” in Latin; It can be understood as the body of knowledge possessed by all humanity that is verifiable, systematically organized and capable of being articulated with each other.

For a knowledge, theory, etc. can be considered as part of the scientific body, you have to meet the two pillars of science and must have passed the test of scientific method.

The two pillars of science are:

Refutability: Any scientific proposition must be capable of being falsified or refuted.
Reproducibility: Any experiment should be able to repeat by anyone.
The scientific method

It is a logical and methodical to establish whether something is true or not process. In simple terms, this process is:

1. REMARK

1a. I notice something odd, interesting, inexplicable, etc.
1 B. I ask myself the question “Why …” or “How …? Or How does …?, Etc.
This is the first step of the scientific method: observation.

2. ASSUMPTIONS

2a. Investigate the information that already exists on the subject.
2b. I propose a possible answer that it becomes more likely.
The second step of the scientific method is to develop a hypothesis.

3. EXPERIMENT

3A. I try to imagine all the possible answers (antithesis).
3b. Design an experiment to determine which of all the possible answers is true.
3c. I performed the experiment, taking very precise notes of everything I do and everything I observe. The third step is the experiment. It is important that the experiment is designed in an impartial manner.

4. ANALYSIS

I analyze what I observed in the experiment and come to a conclusion.
4b. Story everything I did to my friends, showing them my notes.
The fourth step is to analyze and report the results.

5. REVIEW AND COMPARISON UNIVERSAL

5A. Other people repeat my experiment to see if they get the same result.
5b. Based on their experiences, the conclusion adjustments are made.
This is the fifth (and last) step of the scientific method: Review and universal comparison.

At any time during this process, it is very likely to arise more questions, which give rise to further experiments and thus expands the body of knowledge called science.

When the results come together and reviewed and tested many experiments and researchers it can form a scientific law or a scientific theory. It is important to note that a scientific theory is different to what we call theory in common language. Scientific theory is more like a fact, while ordinary (non-scientific) theory corresponds to the scientific hypothesis, which is an unproven idea or proposal. So the theory of evolution is considered as fact and forms the basis of all current knowledge in the field of biology.
