Modern Marvels: The Great Bridge: 8 Miles of Steel
Overview
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.

Episode 11: Sub Zero
Come in from the cold while we explore some of Earth's most frigid places and examine how man copes with sub-zero climates. With the advance of technology, our boundaries have expanded–from the North and South Poles, to the depths beneath the Arctic and Antarctic sea ice, to the Moon, Mars, and outward to Saturn. Enter these forbidding territories, guided by a special breed of experts as we inspect the new US South Pole Station, try on the latest Polartec fashions with anti-microbial fibers, ride on the newest snowmobiles and Sno-Cats, sail through glacial waters on ice-breaking ships, and fly on an LC-130 transport plane. And we'll see what NASA has on the planning board for deep-space exploration, including a beach-ball robot explorer, and learn from scientists studying fish in the waters off Antarctica to understand glycoproteins, which may keep frozen tissue healthy longer for transplantation.
Episode 13: 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.

Episode 10: 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.
Episode 14: Edwards Air Force Base
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.
Episode 9: Firefighting!: Extreme Conditions
This episode of Modern Marvels examines the most extreme raging fires and the firefighters who tame them. The program features interviews with a World War II firefighter who helped contain the London’s blitz fire. We also meet “Hell Fighters” who fight raging oil well fires, and “smoke jumpers” who parachute into forest fires. Firefighting: Extreme Conditions also takes a look at how NASA guards against the very real risk of a fire aboard a space vessel.
Episode 15: Taxidermy
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!
Episode 8: 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.

Episode 7: The Butcher
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.
Episode 17: 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.
Episode 6: Blackbird Stealth
Designed in the late 1950s by aeronautical genius Kelly Johnson at the mysterious Skunkworks, the SR-71 Blackbird was the world’s first stealthy aircraft, designed to over-fly enemy territory with impunity while photographing 100,000 square miles in an hour. While serving six American presidents, it saw action on hot and cold war fronts alike. Interviews with crews and commanders, combined with unbelievable footage, put viewers in the cockpit of this amazing spy plane, flying at speeds of 2,000 miles per hour.
Episode 18: The Doomsday Clock
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.
