Building the Great Cathedrals

s38e01 · 2010-10-20 · 01:00

How did medieval builders reach such spectacular heights using only hand tools to create the great cathedrals? The filmmakers behind NOVA’s award-winning documentary Secrets of the Parthenon take viewers on a dazzling new architectural journey, inside those majestic marvels and jewels of Gothic architecture. Carved from a 100 million pounds of stone and sometimes more than 100 years in the making, some now teeter on the brink of catastrophic collapse. To save them, an international team of engineers, architects, art historians, and computer scientists searches the naves, bays, and bell-towers for clues to how the dream of these temples of human achievement and artistry became a reality. NOVA teams perform hands-on experiments to learn the architectural secrets that the cathedral builders used to erect their towering, glass-filled walls and reveal the hidden formulas, drawn from the Bible, that drove medieval builders ever upward.

Trapped in an Elevator

s38e03 · 2010-11-03 · 01:00

How do elevators work? Are they safe? Why are so many people afraid of them? Across North America, elevators move 325 million passengers every day, and most of the time, people don’t give them a second thought. In Trapped in an Elevator, NOVA reveals the secret life of these ubiquitous machines and investigates personal stories of those who have been caught inside when they do fail. NOVA cameras ride the world’s fastest elevator to the top of the Burj Dubai, the world’s tallest building, and test whether the Burj’s elevator system is ready for the task of moving people to unprecedented heights. On the other side of the world, NOVA follows one of the thousands of elevator maintenance crews in Manhattan that keep New Yorkers moving up and down every day. Then, at the Otis Test Tower—a 28-story high-rise that’s the most over-elevatored building in the world—viewers experience a few heart-pumping moments as a test elevator is sent into free fall. Once brawny but simple machines, elevators are getting a brainy makeover. Computer controls, like those in the elevators at the Marriott Marquis in Times Square, are getting passengers to their destinations faster and more safely than ever before. But will the elevator-wary be comfortable handing over the reins to computers?

Dogs Decoded

s38e04 · 2010-11-10 · 02:00

Dogs have been domesticated for longer than any other animal on the planet, and humans have developed a unique relationship with these furry friends. We treat our pets like a part of the family, and we feel that they can understand us in a way other animals cannot. Now, new research is revealing what dog lovers have suspected all along: Dogs have an uncanny ability to read and respond to human emotions. What is surprising, however, is new research showing that humans, in turn, respond to dogs with the same hormone responsible for bonding mothers to their babies. How did this incredible relationship between humans and dogs come to be? And how can dogs, so closely related to fearsome wild wolves, behave so differently? It’s all in the genes. Dogs Decoded investigates new discoveries in genetics that are illuminating the origin of dogs—with revealing implications for the evolution of human culture as well. NOVA also travels to Siberia, where the mystery of dogs’ domestication is being repeated—in foxes. A 50-year-old breeding program is creating an entirely new kind of creature, a tame fox with some surprising similarities to man’s best friend. Dogs Decoded reveals the science behind the remarkable bond between humans and their dogs and spurs new questions about what this could mean for our relationships with other animal species.

Quest for Solomon’s Mines

s38e06 · 2010-11-24 · 02:00

Countless treasure-seekers have set off in search of King Solomon’s mines, trekking through burning deserts and scaling the forbidding mountains of Africa and the Levant, inspired by the Bible’s account of splendid temples and palaces adorned in glittering gold and copper. Yet to date, the evidence that has claimed to support the existence of Solomon and other early kings in the Bible has been highly controversial. In fact, so little physical evidence of the kings who ruled Israel and Edom has been found that many contend that they are no more real than King Arthur. In the summer of 2010, NOVA and National Geographic embarked on two cutting-edge field investigations that illuminate the legend of Solomon and reveal the source of the great wealth that powered the first mighty biblical kingdoms. These groundbreaking expeditions expose important new clues buried in the pockmarked desert of Jordan, including ancient remnants of an industrial-scale copper mine and a 3,000-year-old message with the words “slave,” “king,” and “judge.”

Secrets Beneath the Ice

s38e07 · 2010-12-29 · 02:00

Almost three miles of ice buries most of Antarctica, cloaking a continent one-and-a-half times the size of the United States. If all that ice melted, seas around the world would rise high enough to flood 12-story skyscrapers in places like New York City. Even a ten percent loss of Antarctica’s ice would cause catastrophic flooding of coastal cities unlike any seen before in human history. Secrets Beneath the Ice explores whether Antarctica's climate past can offer clues to what may happen to our warming planet. Antarctica's has a surprising climate history. In its distant past, it was ice-free, but around 14 million years ago, ice began overtaking the continent as it began plunging into a deep freeze. So when a massive ice shelf the size of Manhattan collapsed in less than one month in 2002, it shocked scientists and raised the alarming possibility that we may be heading toward an Antarctic meltdown. To gather crucial evidence, NOVA follows an ambitious Antarctic investigation--a state-of-the-art drilling probe known as ANDRILL. Drilling deep beneath the Antarctic ice, down through the sea, and three-fourths of a mile into the seafloor, ANDRILL recovers rock cores that reveal intimate details of climate and fauna from a time in the distant past when the Earth was just a few degrees warmer than it is today. As researchers grapple with the harshest conditions on the planet, they discover astonishing new clues--not only about Antarctica’s past, but also Earth’s future. These breakthrough discoveries carry ominous implications for coastal cities around the globe.

Deadliest Earthquakes

s38e08 · 2011-01-12 · 02:00

In 2010, epic earthquakes all over the planet delivered one of the worst annual death tolls ever recorded. The deadliest strike was in Haiti, where a quake just southwest of the capital, Port-au-Prince, killed more than 200,000, reducing homes, hospitals, schools and the presidential palace to rubble. In exclusive coverage, a NOVA camera crew follows a team of U.S. geologists as they first enter Haiti in the immediate aftermath of the tragedy. It is a race against time as they hunt for crucial evidence that will help them determine exactly what happened deep underground and what the risks are of a new killer quake. Barely a month after the Haiti quake, Chile was struck by a quake 100 times more powerful, unleashing a tsunami that put the entire Pacific coast on high alert. In a coastal town devastated by the rushing wave, NOVA follows a team of geologists as they battle aftershocks to measure Earthquake. Could their work, and the work of geologists at earthquake hot-spots around the U.S., lead to a breakthrough in predicting quakes before they happen? NOVA investigates intriguing new leads in its gripping investigation of a deadly scientific conundrum.

Most modern materials are dangerous to the environment, but what about cleaning up our world? Batteries grown from viruses, tires made from orange peel oil, plastics made of sugar, and solar cells that cook up hydrogen–these are just a few glimpses of a new generation of clean materials that could power devices of the future. In Making Stuff Cleaner, David Pogue explores the rapidly developing science and business of clean energy and examines alternative ways to generate it, store it, and distribute it. Is hydrogen the way to go? One scientist is even using America’s abundance of chicken feathers to create a cheap way to make hydrogen cars safer. What about lithium batteries? Does this solve an energy problem or create a new dependency–in this case, on South America for a different kind of limited resource than oil? Can scientists instead develop a process in which batteries run on molten salts found in cheap abundance in the U.S. or on genetically engineered viruses? Pogue investigates the latest developments in bio-based fuels and in harnessing solar energy for our cars, homes, and industry in a fascinating hour full of the “stuff” of a sustainable future.

What can nature teach us in building smarter materials? Can we create materials that sense and respond? “When describing ‘smart materials,’ one analogy scientists give is the evolution from the first Terminator robot, a machine made of metal and circuitry, to the shape-shifting ‘liquid guy’ in Terminator 2,” said Making Stuff producer Chris Schmidt. Smarter looks into the growing number of materials that can shape themselves–reacting, changing, and even learning. An Army tanker trunk that heals its own bullet wounds. An airplane wing that changes shape as it flies. Clothing that can monitor its wearer’s heart rate, health, and mood. For inspirations and ideas, scientists are turning to nature and biology and producing some innovative new developments in materials science. The sticky feet of geckos have yielded an adhesive-less tape. Studying the properties of skin has led to the development of self-healing protective foam. And Pogue literally goes swimming with sharks to understand a different kind of skin that is intriguing scientists. Scientists are modeling a material after sharkskin to develop an antibacterial film that, when sprayed in hospitals, could eliminate MRSA and other anti-biotic resistant bacteria from clinging to surfaces. Pogue also visits a scientist who has created a material that can render objects invisible. “Smarter” concludes with a vision of the future, the ultimate in “life-like” stuff: programmable matter that could create a duplicate of a human being.
