Light enables us to see the world around us. Our sense of sight
provides us with direct information about space and time, the
physical arrangement of the world, and how it changes. This almost
universal shared sensation of vision has led to a fascination with
the nature and properties of light across the ages. But the light
we see is just a small part of the whole spectrum of
electromagnetic radiation, ranging from radio waves to gamma rays.
In this Very Short Introduction Ian Walmsley discusses early
attempts to explain light, and the development of apparently
opposing particulate and wave theories by scientists such as Isaac
Newton and Christiaan Huygens. He shows how light was recognized as
an electromagnetic wave in the 19th century, and the development of
the quantum mechanics view of wave-particle duality in the 20th
century. He also describes the many applications of light, domestic
and scientific, such as microwaves, DVDs, and lasers. We now use
the whole range of electromagnetic radiation to peer both into the
human body and deep into space. Turning to the future of optics,
Walmsley concludes by looking at some of the most exciting new
developments using quantum light sources in communications and
computing. ABOUT THE SERIES: The Very Short Introductions series
from Oxford University Press contains hundreds of titles in almost
every subject area. These pocket-sized books are the perfect way to
get ahead in a new subject quickly. Our expert authors combine
facts, analysis, perspective, new ideas, and enthusiasm to make
