There are concepts that are difficult to define, even though we feel they don't need a definition to clarify their meaning, such as "intuition" or "love." Conversely, there are concepts that are easy to define, even though we feel that a definition falls short of clarifying its meaning. The concept of "science" falls into this latter category. We resort to the dictionary to determine the meaning of a word, but the meaning itself is not sufficient to reveal what a word refers to. In other words, knowing the meaning of the word "science" helps us understand how to use it, but it does not help us understand the essence of science as a cognitive tool. This book aims to fill this gap.

This book addresses the subject of science from three dimensions: a methodological dimension, a historical dimension, and a philosophical dimension. In the methodological dimension, the book reviews the most important tools science uses to reap its benefits, namely logic, mathematics, and experimentation. In the historical dimension, the book looks back in an attempt to uncover the roots of science in ancient civilizations in general, and in Aristotle's physics in particular. The book then moves to the philosophical dimension, examining the philosophy of science and the problems it entails, particularly those related to scientific explanation.

This is a book for every reader who is blessed with scientific curiosity. They will find in it something that will fuel their curiosity and inspire them to think. There is nothing more worthy of thought than science and the questions it raises.
