Optics

The science of light
Paul Ewart

Description

The study of light has been an important part of science from its beginning. The ancient Greeks and, prior to the Middle Ages, Islamic scholars provided important insights. With the coming of the Scientific Revolution in the 16th and 17th centuries, optics, in the shape of telescopes and microscopes, provided the means to study the universe from the very distant to the very small. Newton introduced a scientific study of the nature of light itself and today optics remains a key element of modern science, not only as an enabling technology, but in quantum optics, as a means of testing our fundamental understanding of quantum theory and the nature of reality itself.

About Editors

Paul Ewart obtained a BSc and PhD in physics from Queen's University Belfast and was then an (SERC) Advanced Fellow at the Blackett Laboratory, Imperial College of Science and Technology in London. His current research includes interdisciplinary applications of laser spectroscopy to combustion and environmental physics. He is a professor of physics and head of the Department of Atomic and Laser Physics at the University of Oxford, and the author of Atomic Physics, another book in the Concise Physics series.
