Tập 40
Join us for a second look at the big earth-moving machines used to tackle the most challenging jobs on, under, and off Earth! We'll ride on specialized behemoth dump trucks, delve below sea level to view dredging equipment, and leave the planet altogether to explore earthmoving equipment in space.
Tập 42
Emergency room medicine has only been a recognized specialty since 1989, and it took close to two millennia to get to this point. We’ll examine advances that led to the modern emergency room–from the Byzantine’s establishment of the first hospitals around 1050 A.D. to today’s telemedicine. The prognosis for its future looks good.

Well over two million years before the evolution of modern man, his primitive ancestors were making tools. The use of tools is thought to be one of the keys to human evolution itself and it permeates nearly every aspect of history. We even measure history according to our ability to craft tools; the Stone Age, the Bronze Age, the Iron Age.
Tập 43
Set the sedan’s safety brake and hop on your “hog” for a 2-hour high-speed history of the motorcycle–from the 1868 “steam velocipede” to the early 20th century, when they were a low-cost alternative to automobiles; from Harley-Davidsons preferred by Hell’s Angels and police to motocross riders who take bikes into the air and onto the dirt. We also look to the motorcycle’s future, featuring Jay Leno’s jet-propelled Y2K sportbike and Erik Buell’s bike-without-a-gas-tank creation.
Tập 38
The history of civilization could easily be measured in terms of our ability to make, use, and improve tools–an activity that is at least 4 million years old! At the tip of our toolmaking timeline are power tools. We’ll examine today’s power tool industry, which is booming thanks to more powerful, lighter, and quieter cordless tools.
Tập 44
Since civilization’s earliest days, man has sought protection from those who would rob him of riches, knowledge, and even life. This is the story of the evolving systems designed to safeguard our most precious possessions, and of the enduring psychological war between protectors and thieves, each intent on outfoxing the other.
Tập 37
Though “simulations” date back to cave paintings, devices for interacting with “synthetic realities” are a recent invention. See how simulators are used as training tools for nearly every profession today where hands-on experience is too costly or dangerous–from the 1929 Link Pilot Trainer to simulated virtual realities.
Tập 45
Throughout history the same builders and engineers that paved man's path out of the caves and into the modern world also caused some of mankind's worst disasters. Often a huge calamity is traced back to a tiny cause, insignificant in itself, but triggering a domino effect. We'll revisit notable disasters and search for probable causes.
Tập 36
Since the invention of gunpowder, fireworks have thrilled audiences around the world. We’ll view highlights of fireworks exhibitions throughout history, and go behind the scenes to explore how science and art mingle in this unique, ancient craft. The world’s preeminent fireworks families explain how they create their spectacles.
Tập 46
An exploration of the rich history of one of the world’s greatest technological achievements–the harnessing of power from Niagara Falls. From the “War of the Currents”, a battle between geniuses Thomas Edison and Nikola Tesla, to the Robert Moses Plant, primed to take the powerhouse into the 21st century, we highlight its story.
Tập 35
Tracks the technological innovations that made newspapers what they are today, while exploring the stories of the publishing tycoons who became some of the most powerful men of the 20th century. From the invention of the printing press in the 15th century to computerized newsrooms to the Internet, we examine the history of the news.
Tập 47
Place your bets and join us for an exciting spin through the history of the casino. We’ll go behind the neon lights, free drinks, and 24-hour gambling to see how the gaming industry has evolved from a simple house of cards to a high-tech multi-billion dollar industry.
