ABSTRACT
A rapidly developing branch of philosophy of science occupies a key note in understanding the development of science in the contemporary philosophical domain. It got momentum in the twentieth century though it has an old history. In general, philosophy of science seeks to describe and understand how science works within a wide range of sciences whose rapid development took place between 1500 and 1750. We will discuss the evolution of philosophical thoughts through a discussion on what is science and similar to science; what is methodology of science and how science leads to certainty, truth and knowledge. Also, we need to discuss the role of causality in the explanation of science and its theory.
