Poison
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.

The Arch
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.

Nature's Engineers (2)
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".

Blackbird Stealth!
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.

George Washington Carver Tech
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.

Desert Tech
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.

Howard Hughes Tech
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.

Deadliest Weapons
In this fiery hour, we profile five of man's deadliest weapons, focusing on the inventors, battles, and dark technology behind their lethality. We begin with the deadliest bomb ever created, the Tsar Bomba–a 50-megaton nuclear bomb with a yield thousands of times greater than the one dropped on Hiroshima. During WWI, technological advances in weaponry led to the deaths of over 8-million, and one of the deadliest killers was the machine gun. In WWII, the use of incendiary bombs killed hundreds of thousands of people. Another deadly invention of WWII was the proximity fuse, or VT fuse, that allowed artillery to detonate within a predetermined range of an enemy target. Finally, we examine VX nerve gas, thought by many to be the deadliest chemical agent ever created and suspected to have been used by Saddam Hussein with devastating results. We'll visit Edgewood Chemical BioCenter, which plays a large role in protection and detection for our troops in Iraq.

The Basement
Venture down that creaky staircase to explore the most misunderstood room in the house! From Pompeii to Pittsburgh, the dark, cool, and forlorn spaces beneath our living quarters have always contained things that helped us live comfortably. Ancient Hittites, Phrygians, and Persians carved subterranean rooms for food, water, and wine storage, and for shelter from weather and marauders. For ancient Greeks and Romans, a basement greatly increased a house’s value. Ruins of homes at Pompeii reveal the importance of basements in providing both heat and storage for rich Roman families. Renaissance architects placed kitchens, servant quarters, and laundry rooms there, hidden from the eyes of their aristocratic patrons! Colonial Americans expanded the practice, and by the 20th century, the basement was a routine feature. Come along as we demystify this domestic underworld, which turns out to be an area of innovation, imagination, and creativity.

Bricks
The history of civilization has been built on the back of brick, and it’s been said that “architecture itself began when two bricks were put together well.” From great Egyptian temples to the Roman aqueducts, the Great Wall of China, and the dome of the Hagia Sophia, brick is one of the oldest, yet least celebrated, building materials manufactured by man. In this hard-packed episode, we explore brick’s past, highlighting defining moments, such as the Great London Fire of 1666, the zenith years of brick in the New York Hudson River Valley, and brick as an essential building block in infrastructure and industry. We’ll feature advancements through the ages as well as construction techniques, trends, and the future of brick construction. Essentially, brick is still just burnt clay…it has been around for thousands of years, but continues to serve as the backdrop of the modern age.

Glue
It’s Super! It’s Krazy! And it can be found in everything from carpet to computers, books to boats, shoes to the Space Shuttle. It’s even used in surgery! Without it, our material world would simply fall apart. In this episode, we’ll visit the stuck-up, tacky world of glue. Glue’s sticky trajectory spans human history and we’ll cover it all–from Neolithic cave dwellers who used animal glue to decorate ceremonial skulls to modern everyday glues and their uses, including Elmer’s glue, 3M’s masking and Scotch tape, and the super glues. Remember the Krazy Glue commercial in which a man held himself suspended from a hard hat that had just been glued to a beam? Well, that 1970s vintage ad understates the power of glue. With the help of a crane, we’re going to hoist a 6,000-pound pickup truck off the ground by a steel joint that’s been bonded with glue!

Mountain Roads
Route 66, encompassing eight states from Illinois to California and 2,400 miles, represented an American myth–that something better lay over the rainbow. Route 66 began in the early 20th century when a confluence of technologies–automotive, steel construction, and concrete paving–merged with population explosion, westward migration, and prosperity after WWI. The federal government responded with highway bills that converted existing roadways into an interstate called Route 66. Later, WWII highlighted the need for a strategic system similar to Germany's Autobahn–wider, safer, and more advanced. As federal and state governments worked on a superhighway, millions sought "their kicks on Route 66." By 1985, the abandoned roadway no longer "officially" existed, yet, it remains a destination for nostalgic travelers wishing to recapture a simpler, more adventurous era.

Dredging
They dig, scoop, suck, and spew an ocean of silt and sediment. Dredgers are the mechanical beasts that fuel the world's economic engine by clearing and deepening ports for mega-container ships. The roots of dredging go back as far as the Egyptians, who used their hands to open channels on the Nile to keep crops watered. The Romans, who used harbor dredging to keep a tight fist on Europe, pioneered the "spoon and bag" dredge to speed up the process. Steam power brought about the first large-scale dredges and helped create the Panama Canal. We'll go aboard two of the largest US dredgers and see how they keep waters moving. And in Holland, we meet the biggest players on the dredging world and witness the launching of the largest dredge ever built. From there, we head to Dubai in the Middle East, where 90 square miles of new islands was dredged from the sea and will now create a pleasure world for the rich and powerful.

Lube Job
From chariot wheels of ancient Egypt to hard disks in a computer to the wheels on a Mars rover, machinery can’t function without lubricants. And in today’s technology, there are a mind-boggling number of friction points that must be lubed, and a staggering number of lubricants– petroleum motor oils that keep car engines from burning up, synthetic greases that stay put in the zero gravity of space, and solid coatings that prevent eggs from sticking to a pan. We’ll see how this marvel of chemistry works and how it’s used. Peering into the future, we’ll behold a power generator that employs air as a lubricant, trains using magnetic levitation, which eliminates any need for lubrication, and bio-engineered vegetable oils that promise to take humanity back to one of its very first lubricants. From helping medieval windmills spin, to allowing robotic arms on planetary rovers to move, lubricants are crucial to the advance of technology and literally keep the wheels of progress turning.

Secret Luftwaffe Aircraft Of WWII
German military aircraft designs were decades ahead of their Allied counterparts. To insure the Luftwaffe’s air superiority, Germany’s cutting edge designers conceived and tested highly advanced concepts including swept-wing and vertical take-off aircraft, and long range stealth bombers. Their innovations influenced the world’s military and civilian aircraft designs for much of the post war period. Had Hitler’s forces held on for another few years, the Luftwaffe’s airborne arsenal would have changed the war’s outcome. Using archival footage and computer-generated images, this program traces the development of high production jet fighters, dive bombers, swept-wing fighters, and vertical take-off planes. The centerpiece of the Luftwaffe’s plans, the horton 18 long range jet bomber, was destined to drop a nuclear bomb on the U.S. So advanced was the Horton 18′s design, it became a model for the American stealth bomber fleet of the 1980′s.

Within the US arsenal one such weapon can go into harm’s way, deliver 40,000 pounds of either conventional or nuclear bombs, and slip away unobserved–the B-2 Stealth Bomber. With its origins in single-wing experimentation in Germany in the 1930s, the B-2 was developed under a cloak of secrecy. But when that cloak was lifted, the world was awed by what stood before them. Able to fly over 6,000 miles without refueling, it can reach whatever target the US military wants to attack and deliver its awesome array of laser-guided weapons with pinpoint accuracy. Using state-of-the-art technology, including over 130 onboard computers, and shrouded by a mantle of stealth, it’s undetectable by any radar.

High Risk: Helicopter Linemen
We begin with electrical linemen perched precariously out a helicopter door, repairing 345,000-volt high-tension power lines. They are part of an army of technicians and scientists we'll ride, climb, and crawl with on this episode. They risk their lives so that we can have the services we take for granted–electric power and 21st century communications. They lay and maintain the wire that connects us one to another, as well as America to the rest of the world. The hardwiring of America is a story that is nearly two centuries old. And though satellites and wireless systems may be challenging the wire, it's not dead. Fiber optic cable, lines that transmit light, became a player in information delivery in the late 1970s. We may be entering a "wireless" age, but the infrastructure of wires laid by visionary scientists and industrialists are still vital to America. Wire technology will be with us, continuing to provide service, well into the next century.

HMS Victory
The HMS Victory would play a crucial role in the foremost naval engagement in 19th century maritime history, the battle of Trafalgar. This victory was so decisive that no fleet challenged Britain’s Royal Navy for more than one hundred years. Built with enough wood to cover the Empire State Building one and a half times, propelled by wind and firing solid shots from smooth bored muzzle-loading canons, ships like HMS Victory ruled the waves for over two centuries. Manned by a crew of 850 and capable of firing one and a half tons of iron shot in a single devastating broadside, these eighteenth century floating fortresses were as complex and sophisticated in their day as a nuclear-powered aircraft carrier is today. Using color re-enactments and the actual recollections of those who fought on board, this profile goes below the decks of the famous warship.

Coffee
The sugar industry came of age on the backs of slaves toiling in Caribbean fields, and British desire to control production of sugar and its byproduct, rum. Sugar also played a surprisingly critical part in America's battle for independence. Tour a sugar plantation on Maui, Hawaii to get an inside look at how cane sugar is produced today and learn how the sugar stalks are put through an extensive process of extraction and purification–and how a ton of harvested cane results in 200 pounds of raw sugar. Learn the technology behind creating the sweetener in all of its permutations, including corn syrup, brown sugar, powdered sugar, and cube sugar, and how it's used in candies, soda, and sauces as well as more exotic uses such as in pipe tobacco and processed meat.

Move over pancakes, step aside bacon! Cereal is arguably the true breakfast king, a $9-billion industry with an indisputable place in pop-culture history. Full of surprise, nostalgia, and fascinating facts, our special celebrates the colorful–and crunchy–saga of a distinctly American breakfast. We see how a Presbyterian minister-turned-health-food-fanatic–Sylvester Graham, of “Graham cracker” fame–turned his countrymen from fried pork breakfasts to grain- and bran-heavy diets in 1824. We reveal the rivalries, tricks, and accidents that turned cereal into a breakfast sensation. And we examine the amazing feats of marketing used to promote the product–from creating iconic characters for packaging, to ingenious prizes that drove consumers to the shelves in droves.

Cereal: History In A Bowl
The project was surrounded by secrecy and dogged by controversy from the very beginning. Starting in the late '70s, engineers at Lockheed's legendary "Skunkworks" developed a revolutionary new fighter that was destined to transform aerial combat forever. Little more than a decade later, the F-117 Nighthawk Stealth fighter saw combat for the first time in Panama.

German Small Arms Of WWII
Need a car part or an accessory to give it personality? Since 1903, when Sears dedicated a portion of its catalog, the automotive after-market grew into a billion-dollar juggernaut. We visit Auto Zone, the retail leader, whose largest store carries 25,000 parts. At SO-CAL Speed Shop, a sedan is transformed into a hot rod. Achieving $100-billion in annual sales didn’t happen overnight, but largely on the shoulders of three entrepreneurs–cartoon characters Manny, Moe, and Jack, who were real people. In 1921, they opened their first store in Philadelphia–Pep Auto Supplies. By developing brand names, carrying key parts, and providing hands-on service, they set the standard. Finally, we look at odd products sold by auto stores, discover how Armor All transforms dull interiors into brand-new, and how a tire sealant named Slime may replace the spare tire.

At WWII’s outset, US and UK military aircraft designs were woefully behind Germany’s and Japan’s technologically superior planes. But the genius and ingenuity of innovators on both sides of the Atlantic closed the gap. For America, it was a handful of visionaries and their teams; for Great Britain, a creative and thoughtful spirit emanated from the top leadership on down. In this hour, we recount the untold stories of their cutting-edge designs and solutions, some of which proved decades ahead of their time.

Secret Allied Aircraft Of WWII
It’s another chapter of complex, deadly and controversial engineering failures, using 3-D animation, forensic engineering experts, and footage of the actual disasters to understand what went wrong, and how disaster has led to improvement. In Sun Valley, California, weeks of record rain turn a crack in the middle of a street into a 200-foot long sinkhole. Months later, rain led to the Laguna Beach, California landslide, which destroyed 11 homes and caused millions in damage. On May 23, 2004, four people were killed when the roof of the new Terminal 2E at Charles de Gaulle International Airport in Paris collapses. Other disasters: the 1931 crash of Fokker F-10 passenger airplane with coach Knute Rockne aboard; the sinking of the coal ship Marine Electric off the coast of Virginia; and the blinding reflection of the new Walt Disney Concert Hall in Los Angeles.

At the center of the American Dream is the home–and at the center of its creation or renovation is the lumberyard. We'll explore the options lumberyards provide for builders and renovators–from natural to engineered woods. We'll show how plywood and pressed woods are made, trace exotic woods to jungle and desert, visit a special lumberyard that deals in recycled and antique woods, and go on an underwater expedition as divers locate ancient logs buried in the Great Lakes and New Zealand. We'll see how 50,000-year-old ancient Kauri wood is "mined" from a bog and is now all the rage among those who live in mansions and travel on yachts. From the lowly 2-by-4 used to build a tract home, to a reclaimed set of historic planks used to make a million-dollar bar in a 5-star hotel, this eye-opening program hits the nail right on the head.

The Lumberyard
Nearly 500 years after his death, Leonardo da Vinci still intrigues us. Most people think of him as a great artist, but he was also a remarkable scientist and inventor. His love of mechanics was unparalleled and he filled his notebooks with pages of incredible machines–from weapons of war to "Ships of the Skies", from submarines and scuba suits to robots and an analogue computer…even contact lenses and alarm clocks! How did a 15th-century man envision such modern innovations? If we follow his plans, would any of his designs work? We need wonder no more. With recent technological advances and new materials, we're the first generation able to bring Leonardo's drawings to life–to learn whether his "mechanical dreams" were workable plans. We explore the fascinating intersection of his art, science, and engineering marvels, and use them to offer insight into this "Genius of Geniuses", who remains as elusive as Mona Lisa's smile.
