The challenge of linking Britain and France with a tunnel under the English Channel was both monumental and delicate. It took 18 months just to design and build the 28 foot diameter TBMs, and nearly a year to assemble and position them underground. Modern Marvels takes you through the entire process from start to finish.
Tập 7
“All hope abandon, ye who enter here!” This sentiment has permeated the masonry and clanging bars of prisons built throughout the ages. We’ll see how the philosophy and architecture of today’s American prisons emerged from the sewer cells and castles and dungeons of ancient Rome, medieval Europe, and 18th-century England.

Join us as we span the history of one of the world’s most famous bridges, London’s Tower Bridge. The world’s largest bascule bridge (a counterweighted drawbridge), when it was erected in 1892, it became a postcard image of London. The famed gothic towers of this pioneering steel structure, sheathed in stone, are purely decorative.
Tập 8
Join us for a survey of the world’s greatest inventions in which we examine the wheel, steam engine, railroad, automobile, airplane, printing press, electric light, wireless telegraph, telephone, TV, and computer. Then, travel back in time to the labs, candle-lit offices, and garages to see how these marvels were created.
Tập 1
Beneath every modern city, hidden by manhole covers, drains, and ventilation grates – lies a labyrinth of tunnels, wires, conduits and pipes. They deliver power to our homes, water to our faucets, messages to our loved ones and sometimes – they even move us. Workers create the secret world beneath our feet using everything from shovels, pickaxes and dynamite to multi-million dollar tunneling equipment. The modern subterranean worker, or as they like to be called, “Sandhogs” use time tested methods as well as modern inventions, such as airlocks and computerized mapping techniques to avoid pitfalls and get the job done in the city beneath the street.

When police forces were born in the 1800s, British “bobbies” made due with a billy club. Public wariness and institutional resistance to change held back technological advances for much of the 20th century. But in the last decades, police have been swept up in a technological revolution that has transformed nearly all aspects of crime fighting.

Modern Marvels explores how the basic formula of cement, aggregate and water has changed the world. Concrete has enabled us to create everything from roads and runways to buildings and bridges. The program will explore the history as well as the future of this humble material?from the ancient Romans, who pioneered its use in their vast system of aqueducts, to modern engineers developing a bendable concrete more resistant to the destructive power of earthquakes.
Tập 13
As camping technology develops, it provides greater access to diverse outdoor environments. The earliest camping technology was developed out of necessity. Prehistoric man fashioned rudimentary backpacks and clothing out of bark and animal hide. The explorers and pioneers pushed the boundaries of the West in covered wagons, cooking over open fires, and living off the land. When men headed off to war, they returned with new camping gear and lightweight materials, which enabled further exploration. Today’s Himalayan mountaineers depend on carefully engineered clothing, tents, and boots to reach the highest peaks in the world.
