Modern Marvels: Episode 39
Tóm tắt
Sandhogs work hundreds of feet down, where it is dark, damp, and dangerous, challenging nature’s awesome forces to drive tunnels through solid rock and sinking mud. They drill and blast, bore, mine, and muck. The painstaking process continues for days and yards, months and miles. Tragically, many sandhogs have been killed or injured in the process, but ultimately theirs is a story of triumph and survival. Join us as we review their impressive achievements and history.

In the mid-1960s, the US lost an average of 55,000 people yearly to car crashes. Since then, the number of cars on the road has doubled, but fatalities have decreased by nearly a third. The dramatic reduction is the culmination of research and development that led to safer roads and cars and quicker emergency response. But car-crash technology’s future involves removal of its biggest threat–human drivers! Find out if computers and radar can prevent everything from fender-benders to pile-ups.

Topless, unobstructed–the convertible completely transforms the driving experience and unlike any other car, sets the driver free. During this face-paced hour, experts highlight the history of the world’s most dynamic car design and the essential quality that makes it so unique. From the very first convertible design in 1915 to modern-day marvels of retractable hardtops, we peer under the hoods to see why the convertible remains the car that everybody wants, but only a few are bold enough to own.

For decades, the sound barrier loomed as an impenetrable wall against manned flight that buffeted planes with shock waves as they approached the speed of sound. Scientists thought the barrier couldn’t be breached–until the development of jet technology and rocket fuel at the end of WWII. This is the dramatic story, told through the eyes of many who were there, of the work leading up to October 10, 1947, when 24-year-old test pilot Chuck Yeager smashed through the sound barrier in a Bell EM XS-1 /EM aircraft.

Each day ships, trains, trucks, and planes haul supplies that keep store shelves full and factories moving. At every stop there’s a loading dock–an interface where shipping and storage hook up. You may not think much about a loading dock, but to the transportation industry it’s the very heart of their business. From ancient times to tomorrow’s lights-out facility, where computers and machines will store, sort, retrieve, and load stock without human interaction, we deliver the goods on loading docks.

When Paul Bunyan cried "Timber!", he never foresaw today's cutting-edge, controversial industry that feeds a ravenous, lumber-crazy world–a world striving to protect nature while devouring it. Come into the woods to see how he-men and hi-tech combine forces to topple 4-billion trees annually; journey to 19th-century America, when lumberjacks cut a legend as large as the timber they felled; and travel with a tree from stump to sawmill and learn its non-wood uses–from aspirin to film to toothpaste!

The chance of enemy confrontation by sea, tank, or air battle is small, but terrorist networks operating in the shadows will likely challenge the U.S again. Instead of waiting to react, the military’s new mission is to detect, deter, and defend America from terrorist attack. We examine cutting-edge technology that leads the fight in this new battle landscape, including Smart Bombs, Tactical Ballistic-Missile Systems, GPS-driven technology, Electro-Optical Systems, and the pilotless drone Predator.

Among the most mysterious disasters, tsunamis–Japanese for “harbor waves”–claimed over 50,000 lives in the 20th century! Generated by offshore earthquakes, volcanic eruptions, and landslides, these giant water walls result from large-scale displacement of seabed sediment. Rolling rapidly over the ocean floor, a tsunami rises to rapturous heights when it hits land. Scientists in Japan, Hawaii, Oregon, Washington, and California show the latest technology used to predict these killer waves.

How does technology grasp nature’s most violent, chaotic storm? For half a century, U.S. meteorologists have been building a countrywide system of Doppler Radar, widespread automated data-gathering stations, geostationary satellites, and sophisticated computers to track and study tornadoes. Even with this massive scientific effort, forecasters can only begin to understand why tornadoes form and how to predict them. We’ll look at cutting-edge systems that attempt to measure the unmeasurable.
Tập 34
Engineering disasters can result in personal tragedy, national humiliation, and economic ruin. But buried within their wreckage lie lessons that point the way to a safer future. The fire at the Las Vegas MGM Grand Hotel, the collapse of Seattle’s Lacey V. Murrow Floating Bridge, the car that spurred creation of the National Highway Transportation Safety Administration, and the flaw that grounded the first commercial jet are among the engineering disasters that led to improvements in design and safety.

The challenge: Move millions of soldiers and tons of cargo halfway around the world and into the thick of action. How? Use the biggest ships, the widest planes, and the strongest trucks. Today, military planners move men and equipment further and faster than ever. The United States Transportation Command, answering to the Department of Defense, runs military transport like an efficient private shipping and travel agency. From the Civil War to US Transcom, we track the development of military logistics.
