Modern Marvels: Episode 18
Tóm tắt
Developed in 1947 as an image to symbolize urgency in the Cold War and the threat of nuclear disaster, the mission of the Doomsday Clock has expanded to include non-nuclear global security issues. Maintained by the Board of Directors of the Bulletin of the Atomic Scientists, it’s based at the University of Chicago. In response to world events, they move the clock’s minute hand closer to or away from midnight–doomsday. In this hour, we cover the clock’s history, its effectiveness, and its critics.

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.

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.

From the Impressionist canvas to the Space Shuttle…from customized hotrods to the brilliant orange hue of the Golden Gate Bridge or tiny electronic devices–paint is one of our most ubiquitous products. And paint adds more than just pigmentation. It’s a crucial engineering element, protecting ships from water corrosion, stovetops from heat, and the Stealth Bomber from radar detection. In homes and businesses, it provides a balanced spectrum of light and protects surfaces from wear. In this colorful hour, we discover how this marvel of chemistry and engineering is made, and how it is applied. Come see what’s beneath the surface as we reveal one of man’s most ingenious methods of defeating the elements and adding spice to life!

It began as a tool used by prehistoric man to attract animals to the hunt. Over time it became an invaluable study aid for the natural scientist and a popular hobby for hunters and fishermen. Join us for a tantalizing look at the history of taxidermy, the craft of preserving animal skins and using them to recreate a still life of the animal as it appeared in life. We also check out fiberglass reproduction, which is gaining popularity as fish and game regulations become stricter. Finally, we examine human subjects in taxidermy. Using the very latest process of plastination, the once taboo science and art of preserving and displaying human corpses, now draws crowds in Europe, Asia, and the US, proving the age-old practice continues to mesmerize us!

Examine the colorful history of the premier flight test center, and America’s most important aviation facility for more than 60 years, Edwards Air Force Base in California. Every single aircraft to enter the Air Force’s inventory has been put through its paces at Edwards, along with many Navy and Army aircraft as well. With unprecedented access to several forgotten and abandoned facilities on the base, we are guided by Richard Hallion, former chief historian for the US Air Force. Today, Edwards continues to push the envelope. Among the many cutting-edge projects currently being tested is the Airborne Laser, designed to focus a basketball-sized spot of intense heat that could destroy a ballistic missile.

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.

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.

The Oakland Bay Bridge in San Francisco boasts more superlatives than any bridge on earth. Bridge builders of the depression era defied logic and economics and succeeded in building an 8 mile long structure connecting Oakland and San Francisco. Engineer Charles Purcell built two suspension bridges side by side on the San Francisco side of the bay, then built the largest bore tunnel in the world to connect the west side with Oakland’s eastern shores. Modern Marvels shows you how this great feat was accomplished.

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!
