PCE0015 Chemistry For Engineers Chapter 1 1.1 THE STUDY OF CHEMISTRY Chemistry is the study of matter and the changes it undergoes. Chemistry is often called the central science, because a basic knowledge of chemistry is essential for students of biology, physics, geology, ecology, and many other subjects. Indeed, it is central to our way of life; without it, we would be living shorter lives in what we would consider primitive conditions, without automobiles, electricity, computers, CDs, and many other everyday conveniences. Chemistry also helps us to comprehend the nature of our environment, our universe, and ourselves. It provides essential information about issues such as atmospheric ozone depletion, acid rain, and global warming. Chemistry plays a vital role in our understanding and treatment of diseases such as cancer and AIDS, and it helps unravel the mysteries of the human mind. In fact, the theories of chemistry illuminate our understanding of the material world from tiny atoms to giant galaxies. It is a journey we
