Over the last two centuries, chemistry has changed our daily lives more than any other of the sciences. Chemistry makes our world more colorful, more efficient, more reliable and safer. Pharmaceuticals, cosmetics, toiletries and body care products, airbags and brake fluid - they're all chemical products. Of all the natural sciences, this is the only one to have given rise to an entire industry - Without doubt, chemistry will further go on as the key science within newly evolving areas of knowledge and interdisciplinary research.
So, we do live in a world of matter. From the foods that sustain our lives to various objects that have built up our physical culture, everything is made up of matter. The human body itself is a mixture of matter of differing types. The humans who used materials obtained from nature for centuries, later made new materials out of these to suit their needs. Now the humans have thousand of materials for their use - both natural and human made. The ability that humans acquired to make new materials from natural materials is the basis of human progress. When the structure of the material world and the nature of physical and chemical changes in them were studied, humans were able to make new materials and to control their different properties. The development of chemistry made this progress possible. The contribution of chemistry to fields like, agriculture, industries, health care, food industry, habitat, transport and research has been invaluable. Through chemical processes that scientists develop chemistry comes up every day with answers to ever increasing human needs.
