Modern Marvels: Episode 3
Tóm tắt
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.

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.

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".

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.
Tập 5
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.
Tập 6
Designed in the late 1950s by aeronautical genius Kelly Johnson at the mysterious Skunkworks, the SR-71 Blackbird was the world’s first stealthy aircraft, designed to over-fly enemy territory with impunity while photographing 100,000 square miles in an hour. While serving six American presidents, it saw action on hot and cold war fronts alike. Interviews with crews and commanders, combined with unbelievable footage, put viewers in the cockpit of this amazing spy plane, flying at speeds of 2,000 miles per hour.
Tập 7
In a carnivorous world, a butcher is a necessary link in the food chain, carving a carcass of unsavory flesh into mouthwatering cuts. We trace the grisly trade's evolution–from yesteryear's butcher-on-every-corner to today's industrial butcher working on a "disassembly" line. We tour the infamous remains of the Chicago Stockyards, where Upton Sinclair, Clarence Birdseye, and refrigeration changed butchering forever; witness high-speed butchering; and travel to a non-stop sausage factory. And if you're still squeamish, a USDA inspector offers the lowdown on HACCP–the country's new system of checks and balances on everything from quality grading to E. coli, Salmonella, and Mad Cow Disease. Finally, we visit the last bastion of old-school butchering–the rural custom butcher, who slaughters, eviscerates, skins, and cuts to his customer's wishes.

One of the 20th century’s greatest scientists, George Washington Carver’s influence is still felt. Rising from slavery to become one of the world’s most respected and honored men, he devoted his life to understanding nature and the many uses for the simplest of plant life. His scientific research in the late 1800s produced agricultural innovations like crop rotation and composting. Part of the “chemurgist” movement that changed the rural economy, he found ingenious applications for the peanut, soybean, and sweet potato. At Tuskegee Institute, Dr. Carver invented more than 300 uses for the peanut, while convincing poor farmers to rotate cotton crops with things that would add nutrients to the soil. A visionary, Carver shared his knowledge free of charge, happy in his Tuskegee laboratory where he could use his gifts to help others.
Tập 9
This episode of Modern Marvels examines the most extreme raging fires and the firefighters who tame them. The program features interviews with a World War II firefighter who helped contain the London’s blitz fire. We also meet “Hell Fighters” who fight raging oil well fires, and “smoke jumpers” who parachute into forest fires. Firefighting: Extreme Conditions also takes a look at how NASA guards against the very real risk of a fire aboard a space vessel.
Tập 10
It’s hot, dry, deadly, and hard to ignore with close to 40% of Earth classified as desert. But in this scorching hour, the desert turns from barren wasteland into an environment rich with hope. In the Middle East, desalination of seawater now fills water needs. Americans have created booming desert communities like Las Vegas, where the Hoover Dam produces hydroelectric power and manmade Lake Mead supplies water. Native Americans farmed the desert on a small scale, but 20th-century technology begot greater opportunity. Once desolate areas of California and Mexico now grow agriculture due to irrigation, and the desert’s abundant sunshine allows solar-energy and wind-power production. And in the future, desert technology may enable colonization of planets like Mars. We also take a look at how refrigeration and air conditioning have made life in desert communities tolerable, and examine the latest in survival gear and equipment.
Tập 11
Come in from the cold while we explore some of Earth's most frigid places and examine how man copes with sub-zero climates. With the advance of technology, our boundaries have expanded–from the North and South Poles, to the depths beneath the Arctic and Antarctic sea ice, to the Moon, Mars, and outward to Saturn. Enter these forbidding territories, guided by a special breed of experts as we inspect the new US South Pole Station, try on the latest Polartec fashions with anti-microbial fibers, ride on the newest snowmobiles and Sno-Cats, sail through glacial waters on ice-breaking ships, and fly on an LC-130 transport plane. And we'll see what NASA has on the planning board for deep-space exploration, including a beach-ball robot explorer, and learn from scientists studying fish in the waters off Antarctica to understand glycoproteins, which may keep frozen tissue healthy longer for transplantation.

The Oakland Bay Bridge in San Francisco boasts more superlatives than any bridge on earth. Bridge builders of the depression era defied logic and economics and succeeded in building an 8 mile long structure connecting Oakland and San Francisco. Engineer Charles Purcell built two suspension bridges side by side on the San Francisco side of the bay, then built the largest bore tunnel in the world to connect the west side with Oakland’s eastern shores. Modern Marvels shows you how this great feat was accomplished.

An in-depth look at the technology conceived or developed by America’s first billionaire. A passionate aviator, Howard Hughes built and flew planes that broke speed records, and developed war machines, spy aircraft, and commercial airliners. Despite the impressive heights reached by his technological empire, his health and mental well-being were fragile. During his last years, he wasn’t seen publicly or photographed, rarely left the hotel suites he occupied, and was terrified of germs. But when Hughes died in 1976, he left a huge legacy in aviation and technology. When we board an airliner, view TV via satellite, or marvel at America’s military might, we might do well to remember the risk-taker who flew faster than his peers and was at heart an aviator obsessively dedicated to both the art and science of flight.
