For over a thousand years the Mayan civilization grew and flourished in the rain forests of Central America. Discovered and finally destroyed by the Spanish Conquistadors, it was lost again until explorers brought it to light in the 19th century. Eric Thompson, an archaeologist who has had a 45 year love affair with the Maya, takes NOVA on a pilgrimage through the Mayan world, visiting, on the way, all the great ruined cities he has known for half a century.
How likely is it that a terrorist group will steal plutonium intended for nuclear reactor fuel and put together a blackmail weapon of unprecedented power in the shape of a homemade atom bomb? That question is posed by Theodore Taylor, former A and H bomb designer at Los Alamos, in a recent book, The Curve of Binding Energy. NOVA investigates just how easy it would be to design a bomb using unclassified information.
High in the Hoggar Mountains, in the exact center of the Sahara desert, lives Sidi Mohammed and his family: children, grandchildren, cousins and a few former slave women. Their environment, one of the most ungenerous on earth, provides them with almost nothing. NOVA examines the changing lifestyle of Sidi Mohammed.
Has the case against DDT been proven? A strange question, perhaps, to be asking one year after the US has banned the insecticide, but NOVA dares to ask. Tracing the history of DDT from its discovery through its banning in the States, NOVA asks whether America overreacted with its total ban of this once acclaimed "wonder" chemical.
Just why did Cro-Magnon man living in France's Dordogne Valley some 15,000 years ago take time out from the desperate business of survival to paint pictures in inaccessible corners of his cave dwellings? NOVA joins French and American archeologists as they piece together the lifestyle of these hunters of the last great Ice Age, and try to interpret the meaning of their cave art.
Most of us spend one-third of our lives in a state of which we understand remarkably little—some people sleep for only a few minutes a night, and function perfectly well, while others declare that eight hours isn't enough. NOVA explores traditional notions about how much sleep we need; looks at effects of the sleeping pill, and, perhaps the most baffling of all aspects of sleep—dreaming.
Smashing matter into ever smaller pieces in an attempt to find its fundamental building blocks has produced a confused nightmare of particles. NOVA looks at this on-again, off-again story—one of sciences's most mysterious—and, one of the most expensive, involving some of the biggest machines in the world.
