This is not a conventional book; it is a collection of scholarly articles that present the author's scientific findings. The content of the book develops logically, transitioning from the conceptual and theoretical foundations of research to the analysis of data. Unfortunately, science is often misunderstood. The term "science" is employed with varying meanings and contexts by amateurs, journalists, politicians, scholars, and even scientists themselves. For some, science carries a prestigious connotation; for others, it represents true knowledge. Yet for others, it signifies the objective study of empirical phenomena.
