Modern Marvels: Line of Defense
Overview
Fortification evolved as man tried to defend his territory from attack. From fenced-in hills to walled cities to impenetrable forts, strongholds of the past echo the history of battles for territorial control. In a 2-hour special, we examine various historical defenses, including France’s Maginot Line, a defensive string of forts with enfilading firepower; the Atlantic Wall, 3,000 miles of shore fortifications built by Germany in WWII; and the North American Aerospace Defense Command (NORAD).

Episode 37: Plumbing: The Arteries Of Civilzation
Join us as we take a peek at the plumbing hiding behind your walls and snaking under the floors of your house. We’ll also meet the plumbing students who undergo rigorous training programs in specialized classrooms designed to give them hands on installation experience. We’ll also check out the latest in plumbing technology from waterfall showers to water conserving toilets. This episode of Modern Marvels will examine the past, present and future of the arteries of our civilization; plumbing.
Episode 39: Gadgets
Close cousins to machines and tools, gadgets are mechanical or electronic devices that make life a bit easier. While they don't always fall into clear categories, we know one when we see one. We'll view the craziest, cleverest, and most brilliant gizmos, meet the often-quirky gadgeteers, and glimpse gadgetry of the future.

Episode 36: Inventions of War.
Arising from the horrible carnage, deprivation, and suffering caused by war is a countless array of everyday items–from hairbrushes to microwaves–that directly descend from wartime innovations. Wartime research and development have revolutionized communication, transportation, and medicine. From EM Spam /EM to nuclear power to hairspray and cell phones, life as we know it ironically owes a lot to war. We'll follow the day-to-day life of an ordinary woman and see the influence of war on her life.
Episode 35: Power Plants.
Mankind controls the environment in a variety of ways, whether by capturing the force of a river, harnessing the power in coal or oil, controlling a nuclear reaction, or transforming the light of the sun into electricity. From Thomas Edison and Nikola Tesla to Enrico Fermi and Albert Einstein, the world's greatest minds have enabled us to acquire our light, heat, and power with a simple flip of the switch. Join us for an electrifying hour as we review the foundation for all of this–power plants.
Episode 34: Death Devices
Since the creation of the first laws, societies have demanded the ultimate punishment for certain capital crimes. Throughout history it has been left to a select few to develop the devices that will carry out the mandate of the people. This is the story of those inventors and their dark inventions. Modern Marvels traces the evolution of death technology up to the present and then take a brief look into its future.
Episode 33: Remote Operated Vehicles
Remotely operated vehicles allow us to explore the mysteries of inner and outer space, provide firsthand glimpses of the horrors of nuclear disasters, and offer the vicarious thrill of flying planes or driving cars. From the first remote controlled vehicle, Nikola Tesla’s 1898 steam-powered boat, to underwater ROVs that locate sunken vessels and explore the ocean floor, to their use by NASA in the space program, we see how ROVs extend our range into worlds previously unreachable, unknown, or unsafe.
Episode 32: Combat Training.
Sign up at the ultimate survival school, where soldiers learn to kill or be killed, and learn how 21st-century warriors are training today for the battlefields of tomorrow. We follow combat training throughout history, reviewing survival skills and psychological tools–from ancient Rome to World Wars One and Two–and learn how modern training is enhanced by advanced technology and computer simulation
Episode 31: London Underground
Deep beneath London runs a complex network of many miles of tunnels; and, while traffic congests the roads above, hundreds of trains run through these iron and concrete arteries, carrying millions of people into, around, and out of the City. Here is the story of the “Tube”, the world’s first underground railway, which holds London together–from its opening in January 1863, through its deep-level expansion and electrification, to the fully automated trains of the 21st Century’s Jubilee Line.
Episode 30: Suez Canal
Since the ancient pharaohs’ time, the Isthmus of Suez has been the gateway to trade between East and West. It’s thought that the pharaohs could connect the Red Sea with the Mediterranean using a system of small canals; but the desert sands buried them. Not until mid-19th century did mankind readdress the problem. Since its completion in 1869, the Suez Canal has been a vital link in world trade and a point of controversy in geopolitics. Today, more than 20,000 ships transit the canal yearly.
Episode 29: Assembly Lines
According to the Encyclopedia Britannica, an assembly line is an “industrial arrangement of machines, equipment, and workers for continuous flow of workpieces in mass production operations.” While the basic principles of the assembly line technique have not changed in one hundred years, the people and the products that exploit the technique have. Throughout the hour, we will hear from four generations of assembly line workers who will provide some perspective, heart and soul for this revolutionary production technique.
Episode 28: Farming Technology
The US agricultural process, from seed to shelf, is so efficient that most people don’t think much about it. But food growing and processing is ever more sophisticated, employing computer-guided, ground-shaking machinery, and sometimes controversial techniques. It’s an industry of declining family farms, diminishing returns, yet higher yields. We review the evolution of the tools used to produce food, show the steps in the cycle that bring food to the table, and look at the future of farming.
Episode 27: Machine Tools
No one wants a hand-made car or gun or an airplane. We want things made by machines. Machine tools are power–driven machines–of all shapes and sizes-used to make metal parts. Machine tools built our modern world. Our life would not be possible without them. This show will take a look at these amazing machines in action. Beginning with the story of the steam engine and traveling to modern day “machining centers”–used to make incredibly complex space shuttle parts–we’ll look at the basic types of machine tools and their development. We’ll also look at some of the most modern machine tools of the future, including machines that are changing the way products of tomorrow are made.
