Light Fantastic - Let There Be Light

Light Fantastic is the title of a television documentary series that explores the phenomenon of light and aired in December 2004 on BBC Four. The series comprised four programmes respectively titled: "Let There be Light"; "The Light of Reason"; "The Stuff of Light"; and "Light, The Universe and Everything." The material was presented by Cambridge academic Simon Schaffer.

The first episode shows how the desire, by Greek, Arab and Christian scholars to penetrate the divine nature of light led to modern science's origins. The programme explores the contributions of Empedocles; Euclid; Al Hazen; Roger Bacon; Descartes and Isaac Newton.

BBC - Horizon: The Truth of Troy

Horizon: The Truth of Troy (2004) One of the greatest stories ever told, the legend of Helen of Troy has enchanted audiences for the last 3000 years. In 2004 the movie "Troy" was released, starring Brad Pitt and Orlando Bloom. But is there any reality to the myth? BBC's "Horizon" has unprecedented access to the scientist with the answers! Since 1988, Professor Manfred Korfmann has been excavating the site of Troy. He has never before spoken at this length. He has made amazing discoveries - how large the city was, how well it was defended and, crucially, that there was once a great battle there at precisely the time that experts believe the Trojan war occurred. But who had attacked the city and why? Horizon follows a trail of clues - the ancient tablets written by a lost civilisation, the sunken ship rich in treasure, and the magnificent golden masks and bronze swords of a warrior people. The film reaches its climax in a tunnel deep beneath Troy, where Korfmann has made a discovery that may reveal, once and for all, the truth behind the myth.

Horizon: Infinity (BBC)

By our third year, most of us will have learned to count. Once we know how, it seems as if there would be nothing to stop us counting forever. But, while infinity might seem like an perfectly innocent idea, keep counting and you enter a paradoxical world where nothing is as it seems.

Mathematicians have discovered there are infinitely many infinities, each one infinitely bigger than the last. And if the universe goes on forever, the consequences are even more bizarre. In an infinite universe, there are infinitely many copies of the Earth and infinitely many copies of you. Older than time, bigger than the universe and stranger than fiction. This is the story of infinity.
