Poison (2005)
Since ancient times, man has tried to control the "devil's bounty"–deadly substances found throughout nature. Paradoxically, some of these lethal compounds are now found to possess life-giving properties. In this hour, we explore how ancient Egyptians, Greeks, and Romans came to rely on the pernicious power of poisons and learn the physiological action of these potent killers. During the Renaissance, known as the Golden Age of Poison, the deadly practice helped shape European history–most especially that of the Catholic Church. We continue our investigation into the gas attacks of WWI and up to the 21st century, when a new and serious threat of bioterrorism plagues the globe. Finally, we peer into the future with scientists experimenting with poisons and venoms from the plant and animal kingdoms that may play an important part in healing diseases such as arthritis and even cancer.
Car Tech of the Future (2005)
Engage the satellite navigation, fire-up the fuel cell, and activate the radar-guided cruise control! You’re in for the joyride of your life as we investigate what drives and will drive our vehicular destiny. In this 2-hour special, we talk to auto industry engineers, designers, historians and futurists, and meet carmakers standing at the threshold of a brave new automotive world and on the verge of technical innovations that might prove as far-reaching as the switch from horses to horsepower.
The Arch (2005)
Join us as we explore the vast and varied world of the arch, one of the strongest and most versatile structures made by man. Deceptively simple, an arch can support tremendous weight because its structure is compressed by pressure, and it provides a much more spacious opening than its predecessor–post and lintel construction. Although ancient Egyptians and Greeks experimented with the arch, the Romans perfected it. Medieval Arabs incorporated it into stunning mosque architecture, soon followed by Europe's great medieval churches. In the 19th and 20th centuries, the steel arch became a favorite of architects and structural engineers. Dam builders employed it horizontally, using the water behind the dam to provide the pressure to compress it. And tomorrow, the arch will continue to serve mankind in every form–from nanotechnology to domes on Mars and beyond.
More Nature's Engineers (2005)
Think man is unique within the animal kingdom? You might not after this hour that features an amazing collection of earth's non-human inhabitants that use tools, build intricate structures, create traps to capture prey, and perform complex procedures, including farming. From Egyptian vultures utilizing stones to crack open hard-shelled ostrich eggs to chimpanzees using a "tool kit" to extract termites from their nests, we learn that our ability to create tools is not exclusive. Other mammals create subterranean structures, including those prodigious diggers Prairie Dogs, and many animals and insects make devices to augment hunting, such as the Ogre-faced Spider that spins a small web to throw down on unsuspecting passersby. And we're not the only ones to work as a unified, multi-skilled force. Aphid-Raising Ants protect and care for herds of plant juice-sucking aphids that they "milk".
World's Biggest Machines 3 (2005)
Giant robots on the factory floor and in outer space. A floating fortress that's home to 6,000 military personnel, which is almost as long as the Empire State Building is tall. And a diesel engine with 108,000 horsepower. (You read that right.) These giants must be seen to be believed! In this episode, we travel over land and sea to find these and more of the biggest, baddest, most audacious feats of engineering in the world.
