Yet it represents only 43% of the world’s total mail volume. From ancient Sumerians to Pony Express, from airmail to E-mail, we follow the long journey of mail.

A study of the discoveries, inventions, and technological advances that have helped us understand and predict weather accurately. From simple observations made by early humans, to early instruments such as thermometers and barometers, to Doppler radar and satellite imaging, we’ll see how man has tried to harness weather.

First there were balloons and blimps. Then, visionaries enlarged, reinforced, and motorized them and the airship was born. The biggest aircraft ever flown, they remain one of the most romantic aerial creations. In all, 161 rigid airships were built before spectacular crashes, including the EM Hindenburg /EM , put an end to the era.

Bombs…the most feared and powerful weapon in any nation’s arsenal.

Throughout history, the builders and engineers who paved our way out of the caves and into the modern world have also caused some of our worst disasters. What happens when their calculations prove wrong and it all comes tumbling down? From Hammurabi’s days, when the first building laws were instituted, to today’s potential nuclear or chemical disasters that can spell death for thousands, we’ll take a harrowing 2-hour tour through some of history’s greatest engineering mistakes.

To run faster, jump higher, and play longer–the ultimate goal of all athletes. But when training runs its course, science and technology jump in. Explore the history and technological advances in everything from athletic shoes to football gear. And leap into a future filled with radar-enhanced baseballs and virtual-reality stadiums.
Tập 22
Even in ancient times, city dwellers needed a scenic break from the urban landscape. But parks play a more important role than mere relief from tension–they also keep temperatures down and supply much-needed oxygen in congested cities. Come along for a stroll through New York City’s Central Park and L.A.’s Griffith Park.

The story of medical imaging, the technology that allows us to see inside the human body, is full of amazing stories. Learn how X-rays were discovered in 1895, completely by accident; how ultrasound was developed to locate enemy submarines, and how the CAT Scan might never have been built if it weren’t for The Beatles!
Tập 23
Espionage has been used for at least the last 4,000 years. And where there are spies, you find gadgets! We focus on the last 100 years of cloak and dagger technology–from early code-breaking computers to satellite reconnaissance–and take a look at the James Bond-type gadgets of the Cold War.
