Modern Marvels: Episode 18
Tóm tắt
They are elements that occupy a select portion of the periodic table and are so essential to America's economic and military might that they are stored in the National Defense Stockpile in case of all-out war. We plan a riveting visit. Some of the vital heavy metals that we survey include copper, uranium, lead, zinc, and nickel. We also take a look at superalloys--consisting of steel combined with chromium, cobalt, and dozens of other heavy metals--that resist corrosion and perform increasingly elaborate functions. From Earth to space, from cosmetics to vitamins, in a million different ways, heavy metals are here to stay!

An old-fashioned style of cooking, barbecue has evolved into a modern food craze and spawned a multi-billion dollar industry. We digest famous barbecue cook-offs and visit long-established barbecue restaurants like Arthur Bryant's in Kansas City, where the huge grills and taste thrills of true barbecue are more popular than ever. At home, three out of four US households own a grill. After WWII's end, the phenomenon of backyard barbecuing swept the nation, thanks to inexpensive and mass-produced grills, including the kettle-shaped Weber. Our tour of Weber's modern factories shows how they keep pace with demand by manufacturing more choices than ever, including portable mini-grills. We also examine the variety of fuels available for the savory selection of spicy sauces and rubs. Join us as we devour the mouthwatering flavors of BBQ in this episode.

Join us as we investigate the transition from Industrial to Information Age–a digital decade dedicated to ergonomics and entertainment. The microchip ushered in an era that revolutionized the way we work, play, and communicate. And we tour Silicon Valley–birthplace of some of the greatest inventions from an amazing time of change, including the modern personal computer. Steve “Woz” Wozniak tells us about the evolution of Apple computers, and we talk to Sony–makers of the Walkman, Betamax, and the first CD players. A visit to the Computer History Museum shows fun technological “artifacts”, primitive by today’s standards. At Intel, makers of the first microchips, we learn why technology moves at such a fast pace. We also take a ride in a DeLorean DMC-12 sports car–few things moved faster.
