The World's Longest Bridge

Bridges are the lifeline of Japan. Since the 1930s, the island nation has dreamt of linking its many parts as a whole. But WWII diverted the incredible resources needed to accomplish this, and only since 1960 has the dream moved again, slowly, toward reality. The final step in this massive undertaking was the Akashi-Kaikyo Bridge, currently the longest single-span suspension bridge in the world. This marvel of architectonics stands as a testament to the genius of Asian engineering and, judged in a context that perhaps the Japanese understand best, as the most beautiful bridge in the world. We’ll watch it rise, from sketch to completion, and see how it fared during the massive Kobe earthquake.

Next, we stir up a hotter topic–the connection between global warming and fossil fuels–and ask if they’re cooking up a sudden, new Ice Age. And we examine 21st-century technologies that typify the dual-edged sword of EM Doomsday Tech /EM with massive potential for both creation and destruction–nanotechnology (engineering on a tiny scale), robotics, and cybernetics. We witness amazing applications in the works, wonder at the limitless promise, and hear warnings of a possible nano-doomsday, with tiny, out-of-control machines devouring everything around them.

More Doomsday Tech

The second deadly hour examines more threats–both natural and manmade–that may endanger civilization. From the far reaches of space to tiny viruses, doomsday sources are many. But so are technologies used to keep doomsday at bay. Asteroids of significant size have hit our planet before and likely will again. Asteroid hunters demonstrate the Near Earth Asteroid Tracking (NEAT) program and methods being developed to destroy earth-aimed asteroids. Then, it's onto bioterrorism's sinister technologies–how highly virulent agents like smallpox and plague can be weaponized. Next, an ex-hacker turned cyber-security expert shows how vulnerable the nation's computers are to cyberterror. Finally, we visit the controversial world of biotechnology. Could genetically engineered crops backfire? Does a brave new world of genetically selected beings loom in our not-so-distant future?
