9.1 Physics and Science

Science is a collective knowledge about natural phenomena, processes, and events occurring around us. The process starts with asking a question: how and why do things in the world behave as they do? We try to look for orderliness and regularities among various phenomena apparently of diverse nature. Such study of nature gave birth to a single discipline known as Natural Philosophy, now known as science.

There was a tremendous increase in the volume of scientific knowledge at the beginning of the nineteenth century. This made it necessary to classify the study of nature basically into two main disciplines:

1. Biological sciences, which deal with living things.
2. Physical sciences, which are about the study of non-living things.

Physics is an important and basic part of physical sciences, beside other disciplines such as chemistry and geology.

Do You Know? Physics is the fundamental science that deals with the constituents of the universe, that is, matter, energy, space, time, and their mutual relationships and interactions. It strives to understand how the universe works, from the smallest subatomic particles to the largest stars and galaxies.
