For many centuries people have wondered how our world works. In early times, mythical beings and magical powers were used to explain how and why certain things happened. Only much later did awareness of energy in its many forms come to be accepted. This book follows the search for an understanding of what energy is, from the ancient Greek philosophers to the scientific discoveries of the early 21st century. It also looks at how science might help to meet our future energy needs.
