Chemistry is the study of matter and its changes. This includes everything in the universe from a simple hydrogen atom to very large replicating molecules in life processes. Chemistry is involved with the development of: medicines that control and cure diseases; food production through specific and safe agricultural chemicals; consumer products such as cleaners, plastics and clothing; new methods of energy production, transfer and storage; new materials for electronic components; and new methods for protection and cleanup of the environment. Chemistry majors are needed to help solve some of society's most difficult technological problems through research, development and teaching. Many people think that chemistry is "too hard." Although it is somewhat challenging, any reasonably intelligent student with the right attitude and study habits can succeed in chemistry!
