In the Beginning, in a burst of pure radiant energy, light came into being and in that brief instant of creation the Universe came into existence some fourteen billion years ago. Within the first three minutes of the big bang pure energy condensed into matter. From this matter stars and galaxies came forth and through the process of nuclear fusion, heavy elements were forged in the hearts of distant and massive suns. It is the existence of these elements that make the reality of living things a possibility. We owe are very existence to that very instance when the laws of physics through accident or design (depending on your philosophical and religious proclivities dear reader) declared, eons ago –“Let there be Light”.
So my dear readers, in the earnest hope that this New Year and the years to follow, will always be radiant with the promise of hope and good fortune for each and everyone of you I would like to offer you the following documentary for your viewing pleasure: Simon Schaffer's fantastic four part documentary "Light Fantastic" that was produced for BBC 4. In the episodes that follow science historian Simon Schaffer takes us on a voyage of discovery through time to follow humankind’s quest for enlightenment to discover the true nature of light.
The entire series can be purchased on DVD from DVDRare.
1. Let There be Light
Greek and Arab scholars and later Europeans such as Descartes and Newton all tried to understand light to gain a better understanding of God. Episode one shows how much of modern science's origins came from the desire to penetrate the divine nature of light.
2. The Light of Reason
The second programme explores the link between the development of practical tools that manipulate light and the emergence of new ideas. For example, Galileo's observation that the sun did not go around the earth, was made with a telescope that had been invented for Venetian soldiers and traders.

3. The Stuff of Light
Episode three charts the discovery of the true nature of light and its impact on the modern world. All of today's technologies - electricity, mobile communications and our ability to illuminate the world 24 hours a day - stem from unravelling the mystery of light.

In the final programme Simon Schaffer finds that as more people were able to manipulate light, the more puzzling and tricky it became. This led to investigations into the strange relationship between light, the eye and the mind, and the development of new technology such as photography and cinema.
