Introduction to Physical Science/Chapter 1 Introduction

Science is not about facts and figures. It's a knowledge that can be tested and proven. Science is a study of knowledge to study natural laws.

We are surrounded with science in all aspects of life. In plants, photosynthesis is occuring, metabolism is also happening in their cell, respiration is also occuring and many more. We humans are also living and walking example of science. We are also made up of cells and cells are made up of atoms. Sun, Sun is a big celestial body made up of hydrogen and other gases and in sun's core nuclear fusion is occuring which convert hydrogen into helium and due to this earth recieves light and due to this light plant carry out photosynthesis and we use the product to photosynthesis to carry out our daily requirements.

We are living the life of biology made up of chemistry and working by the principles of physics.

Science can be fundamentally divided into three different subjects which are physics, chemistry and biology and other scientific field are derivatives of these three fundamental subjects
