Chemistry applies to most processes occurring in the world.
Chemists study the action of molecules transmitting nerve impulses, determine the structure of biological macromolecules supporting the trunk of a Douglas fir tree, develop polymers for use as coronary artery patches, and prepare superconducting materials used in magnetic resonance imaging instruments. In addition, they study soil nutrients to maximize crop yields, develop methods to care for our environment, synthesize new materials, and develop theories about chemicals and their reactions. Chemistry provides a critical foundation for our understanding of the biological and physical principles of our world. The study of chemistry is directed toward understanding the fundamental nature of matter, the changes in its composition, and the energy changes accompanying these transformations. To study chemistry is to gain an understanding of the world around us by learning chemical principles, integrating them with other fields of study, and applying chemical knowledge to real world problems.
