Laser : Light of the 21st Century
When first invented 18 years ago, lasers were called "a solution looking for a problem;" nobody could think what to do with them. But in fact research scientists immediately began to exploit their pure colors and near-perfect focusing ability. Today lasers have grown into a billion-dollar business. They are used in construction, manufacturing, clothing, dentistry and medicine. And the future uses of lasers are likely to be of major significance as the means of achieving nuclear fusion and as a very high efficiency communications medium.
More from Season 5
Episode 1
In The Event of Catastrophe
Can a nuclear war be survived? Some members of the defense community say yes. NOVA explores the possibility.
Episode 2
The Green Machine
Botany is a neglected science and plants are all around us, but unfamiliar. NOVA examines our state of knowledge of how plants work: growth hormones, responses to light and shade, photosynthesis, root mechanisms and twining responses.
Episode 3
Blueprints in the Bloodstream
It has been known since the turn of the century that there are four human blood groups, based on different red cells and serum characteristics. NOVA looks at the more recent discovery that the different white cell types, as determined by a variety of different molecular markers on the cell surface, open up the possibility of the prevention of disease.
Episode 4
One Small Step
Part one of a two-part series on the subject of man in space, NOVA examines the history of NASA—from the origin of the space race through the triumph of the Apollo programs. By tracing the history of three key programs—Mercury, Gemini, Apollo—we show how the basic challenges surrounding space flight were answered: rendezvous and docking, life support, weightlessness, space sickness, equipment reliability and so on.
Episode 5
The Final Frontier
Second of the two-part series on space programs, NOVA looks ahead to the future, post-Apollo and the role that man in space will play, including the possibility of space colonization—huge orbiting space stations where people live and work in an earth atmosphere under artificial gravity.
Episode 6
BaMiki BaNdula: Children of the Forest
In the rain forests of Zaire, in the heart of Africa, live the Mbuti Pygmies. The Pygmy way of life has always been extraordinarily difficult to capture on film, though many have tried. NOVA presents a rare portrait of an elusive people, made by an independent filmmaker who lived with the Pygmies and won their trust.
