What is Science?

Science is a particular way of understanding the "matter" .
It involves a lot of questions such as:
                        How did it happen?
                        Where does it come from?
                       When did it happen?
                       What are the causes?
                      Who did it? Why this happens?

Scientists have a specific method called scientific method to
understand a phenomena, to solve a problem or analyze an
issue. It involves steps as follows:
                   1. Identify an issue ------------------------ Issue
                   2. Assess all the factors available ------ Assessment
                   3. Set an hypothesis------------------------- Hypothesis
                   4. Collect related information-------------  Reference
                   5. Design experiments---------------------- Study
                   6. Support, reject or modify the hypothesis
                   7. Design experiments---------------------- Study
                   8. Validate the hypothesis, establish a theory.

The theory or the model has three important elements:
observable (detectable), measurable and repeatable.
