2 - Introduction and history
For many centuries, people searched for the best approach to the investigative process. One of these initiatives included providing arguments to explain the way things ought to be (e.g., the Greek philosophers), but it turned out to be unreliable, because arguments cannot determine the truth of a statement; this requires proof. A better approach is to experiment and observe carefully. The results of this approach are universal because a skeptic person can experiment and observe on his or her own. These ideas gave birth to the Scientific Method.
