#3 - Making North America: Human
Season 42 - Episode 20 - Aired 11/18/2015
Explore the intimate connections between the landscape, the colonizing of the continent, and the emergence of our industrial world. Beginning with Native American ancestors who crafted hunting weapons from stone traded across hundreds of miles, the program shows how pre-Columbian civilizations developed an expert knowledge of the landscape and its resources. With the arrival of Europeans, North America’s hidden riches became to key to prosperity, from the gold rush to today’s oil and gas boom. As a result, human activity has transformed the continent on a scale that rivals the geological forces that gave birth to it billions of years before. Yet, scientists warn of sleeping giants like the Cascadia fault, and the earthquake/tsunami one-two punch it could unleash on the Pacific Northwest. Even as we re-mold the continent to suit our needs, geologic processes inexorably continue, and they raise potential risks of catastrophe to our human civilization.

#4 - Colosseum: Roman Death Trap
Season 42 - Episode 4 - Aired 2/11/2015
One of the ancient world's most iconic buildings, the Colosseum is a monument to Roman imperial power and cruelty. Its graceful lines and harmonious proportions concealed a highly efficient design and advanced construction methods that made hundreds of arches out of 100,000 tons of stone. In its elliptical arena, tens of thousands of gladiators, slaves, prisoners, and wild animals met their deaths. Ancient texts report lions and elephants emerging from beneath the floor, as if by magic, to ravage gladiators and people condemned to death. Then, just as quickly, the Colosseum could be flooded with so much water that ships could engage in sea battles to the delight of the crowd. Now, archaeologists and engineers are teaming up to recreate a 25-foot lifting machine and trap door system capable of releasing a wolf into the Colosseum's arena for the first time in 1,500 years. Do they have what it takes to replicate the innovation and ingenuity of the Romans?

Whether serving as Christian church, Islamic mosque, or secular museum, Hagia Sophia and its saring dome have inspired reverence and awe. For 800 years, it was the largest enclosed building in the world—the Statue of Liberty can fit beneath its dome with room to spare. How has it survived its location on one of the world’s most active seismic faults, which has inflicted a dozen devastating earthquakes since it was built in 537? As Istanbul braces for the next big quake, a team of architects and engineers is urgently investigating Hagia Sophia’s seismic secrets. Follow engineers as they build a massive 8-ton model of the building’s core structure, place it on a motorized shake table, and hit it with a series of simulated quakes, pushing it collapse—a fate that the team is determined to avoid with the real building.

Season 42 - Episode 5 - Aired 2/18/2015
More than 2,000 years ago, the thriving city of Petra rose up in the bone-dry desert of what is now Jordan. An oasis of culture and abundance, the city was built by wealthy merchants whose camel caravans transported incense and spices from the Arabian Gulf. They carved spectacular temple-tombs into its soaring cliffs, raised a monumental Great Temple at its heart, and devised an ingenious system that channeled water to vineyards, bathhouses, fountains, and pools. But following a catastrophic earthquake and a slump in its desert trade routes, Petra's unique culture faded and was lost to most of the world for nearly a thousand years. Now, in a daring experiment, an archaeologist and sculptors team up to carve an iconic temple-tomb to find out how the ancient people of Petra built their city of stone. Meanwhile, scientists using remote sensors and hydraulic flumes uncover the vast city and its sophisticated water system. The race is on to discover how these nomads created this oasis of culture in one of the harshest climates on Earth.

With unprecedented access inside both Fukushima nuclear power plants, NOVA speaks with workers who were there during the harrowing days—a crisis that began as a natural a disaster but was made worse by human beings. But why did the worst happen at one plant while another that faced nearly identical challenges emerged unscathed? It may come down to the skill and knowledge of one man, who has worked there since they started construction. These are crucial questions as the company that runs both plants, TEPCO, tries to clean up an unprecedented radioactive mess and seeks to reopen the plant that was just barely saved.

After nine years and 3 billion miles, we will finally get a close look at this strange, icy world, but only if the craft can survive the final, treacherous leg of its journey, which could take it through a dangerous field of debris. If it does, New Horizons is poised to make dramatic new discoveries, not just about Pluto, but about the vast realm of icy bodies lurking beyond Neptune, relics of the earliest days of the solar system’s formation. Back on Earth, the planetary scientists who have spent decades working on this mission anxiously await a signal from their spacecraft. Our cameras will be there to witness the moment. If all goes well, we’ll see Pluto’s mysterious surface in unprecedented detail and learn new secrets about other alien worlds at the far limits of our solar system.
