Written in an easy, flowing style, Mr.Clegg's book is full of interesting and apposite facts about light and the people who gave us the basis of our current understanding. A master storyteller, he does not pontificate or try to blind the reader with science, rather, he opens our eyes to the possibilities afforded by that science - describing it all in layman's terms, but definitely not patronising or 'dumbing-down'.

The first chapter is a taster of the future potential of experimentation with light, outlining some tremendous possibilities. Then we are treated to an overview of the perception of light by the ancients, whose theories were taken as gospel during the Dark Ages and only began to be questioned in the Middle Ages - but even then heresy loomed large for anyone trying to usurp the accepted 'facts'.
Continuing, potted biographies of the greats of science; Bacon, Davinci, Galileo, Descartes, Newton et al, give us a clearer picture of the problems that the new wave of scientists faced.

Then we get into the meat of the problem - what is light made of? (which is still not fully answered). Fascinating insights into recent and modern theory and fact leaves one's mind boggling, trying to contain the concepts, speeds and distances involved.

Immensely readable, I encourage anyone with even a passing interest in light, science or history to read this book - they will be rewarded by a new persective of the world.
As further reading, I also recommend 'Unweaving the Rainbow' by Richard Dawkins.*****.
