A large machine turned water city, cruise ships are exciting and new.

Rising from a stretch of desert with nothing but remoteness to recommend it, Las Vegas became a glittering wonderland for dreamers. We’ll take a look at the forces that made Las Vegas a place unlike any on earth.

With technological advances, our ancient struggle against the sea has turned into a luxurious holiday. Come aboard for a peek at the elegant life on these floating resorts.

The story of the construction of our grand national highway system, from its beginnings in 1912 (it was conceived by auto and headlight tycoons) to its completion in 1984 (when the last stoplight was removed–and buried).

Many rivers quenched the thirst of millions in the American west and around the world. Without these aqueducts, some of the earth’s largest cities would turn into gigantic ghost towns. Their technology has been in use for over two thousand years. But today these engineering marvels cost billions of dollars to build, requiring thousands of men to toil for years on end. Aqueducts have made some men famous and others fabulously wealthy. In Los Angeles one man’s vision took one hundred thousand men to complete and a great city was truly born. In Northern California the most famous conservationist of our time waged the political fight of his life in an attempt to save one of nature’s most spectacular valleys from San Francisco’s demand for more water.

When “poliomyelitis” swept the nation, thousands died or were disabled before American ingenuity, trial and error, and blatant acts of desperation led to one of the greatest scientific breakthroughs in history. We’ll see how polio shaped the vision of FDR, and catapulted the young unknown doctor Jonas Salk to international celebrity.

Meet some of the most important, yet least-recognized, warriors–the battlefield engineers who lay the groundwork for oncoming conflicts. We'll cover combat engineering from ancient Rome to modern-day Iraq, and take a look at the "Next Big Thing".

While a civilization’s greatness is reflected in the achievements of architects and engineers, equally impressive are spectacular acts of destruction throughout history. The cycle of construction and destruction reflects the shifting values of any given era. We’ll trace the evolution of planned destruction from ancient to modern-day.

The Atlantic Wall explores the construction of the shore fortifications built by the Nazis during World War II. We highlight the logistics of construction, types of fortifications, weapons, and obstacles used in the wall. The Nazis attempted to fortify 3,000 miles of occupied European coastline before the Allies launched thier attack on occupied Europe. Finally the Allied D-Day invasion planning and execution, with its associated propaganda and deception, are detailed.

Plastics are everywhere–the home, the workplace, the car, the human body, outer space, and most conspicuously, the garbage heap and landfill. Artificially created test-tube material, plastic can’t be returned to nature. Will we drown in a sea of plastic? Join us as we review this protean substance’s past and future.

To run faster, jump higher, and play longer–the ultimate goal of all athletes. But when training runs its course, science and technology jump in. Explore the history and technological advances in everything from athletic shoes to football gear. And leap into a future filled with radar-enhanced baseballs and virtual-reality stadiums.

Bombs…the most feared and powerful weapon in any nation’s arsenal. What began as incendiary devices in the 7th century has evolved into weapons that can literally blow the human race off the face of the earth! From the use of diseased carcasses flung over castle walls to Greek Fire to today’s smart bombs, we review the evolution of bombs.

The ability to transmit sound in stereo transformed the music of life into a rich symphony of sound. For over 100 years, enthusiasts and scientists have worked to create the ideal listening experience. From Thomas Edison’s early phonograph to today’s digital revolution, we examine this multi-billion dollar business.

Through rain, snow, heat, or gloom of night, we expect postmen to deliver the mail. The U.S. Post Office handles over 603-million pieces of mail daily. Yet it represents only 43% of the world’s total mail volume. From ancient Sumerians to Pony Express, from airmail to E-mail, we follow the long journey of mail.

Does anybody really know what time it is? Set your clocks as we explore the relativity of time from antiquity–when man attempted to chart time with methods ranging from shadows, candles, and water–to today’s atomic clock system–accurate to within one second every two-million years.

Meet the Strong Men and Women who go beyond mere fitness to pursue major muscle mass–from ancient Greeks, to performers in the 1800s astounding audiences with feats of strength, to the body builders of California’s Muscle Beach! Lou Ferrigno and other stars share stories of the pursuit of muscle. Also looks at the effect of steroids.

Step up to the plate and play ball as we take you on a tour of those amazing edifices of the national pastime–baseball stadiums! From the sandlots and wooden ballparks of the 1800 and 1900s to the monolithic multipurpose stadiums of today, baseball parks have grown into technological wonders that pull in and cost millions.

Though “simulations” date back to cave paintings, devices for interacting with “synthetic realities” are a recent invention. See how simulators are used as training tools for nearly every profession today where hands-on experience is too costly or dangerous–from the 1929 Link Pilot Trainer to simulated virtual realities.

Emergency room medicine has only been a recognized specialty since 1989, and it took close to two millennia to get to this point. We’ll examine advances that led to the modern emergency room–from the Byzantine’s establishment of the first hospitals around 1050 A.D. to today’s telemedicine. The prognosis for its future looks good.

The very spirit that drives man to dream up ever more fantastic creations can also conceive changes that destroy old treasures. We look at great artistic and engineering feats that fell prey to the ravages of nature, the wastes of war, and the indifference of booming metropolises.

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.

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.

From amazing ancient Roman aqueducts and arch bridges, romantic Renaissance spans, 19th-century railroad crossovers, to monumental marvels of our time, bridges played a key role in the human quest to connect and unify. We'll trace the history of bridge types, including suspension, arch, beam, truss, and cantilever designs.

“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.

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.
