The series uses sophisticated 3-D animation in short video modules to explain a variety of concepts about light and the historical thinking about each.

Starting with Einstein's theory of relativity, Physics of light explores the true nature of light, peers inside the atom, and looks ahead to the most cutting edge theories in physics. The six-part series uses the medium of light to explore the concepts of physics from familiar theories, such as Newton's law of gravity, to the latest in scientific research, like string theory and M-theory.

"The City Dark chronicles the disappearance of darkness. The film follows filmmaker (and amateur astronomer) Ian Cheney who moves to New York City from Maine and discovers an urban sky almost completely devoid of stars. He poses a deceptively simple question, 'What do we lose, when we lose the night?"--Container.

Our planet is lit up 24 hours a day, seven days a week. We're addicted to light of all kinds, and like anything else that's addictive, is too much a bad thing? Join leading scientists in the lab and in the field to discover how much harm light at night may be causing people and to learn about the ground-breaking steps being taken to protect us.

On a planet with six suns, the inhabitants have never known darkness, until the suns start disappearing one by one.

Commercial motion pictures were invented at the Edison Laboratory between 1888 and 1893. Perhaps none of the component parts were strictly new, but the ability of Edison and his staff to reorganize them for a specific purpose was an extraordinary cultural achievement. In 1894, Edison was the sole producer of motion pictures in the world. Many Edison films continue to be impressive as the company employed such accomplished early directors as John Collins...
