Chemistry is a branch of science which is associated with our daily life in a number of different and important ways. Anything we touch, smell, see or taste contains one or more chemicals. The air we breathe, the food we eat, the clothes we wear and the water we drink are all composed of chemicals. Toothpaste, perfumes, soaps and detergents are made up of chemicals. With the improvement in technology, the impact of Chemistry in everyday life is increasing. Whether it is food, clothing, entertainment, office work, industrial work, teaching, simple household chores, work in hospitals, hotels, mills or libraries, chemistry is involved everywhere. Thus, chemistry is connected to all other fields such as engineering, medicine, agriculture, industry, biology, economics, geology, etc. Since chemistry joins together physics and mathematics, biology and medicine and the earth and environmental sciences, for this reason, it is also known as the central science.
