NOVA: Episode 9
Tóm tắt
Our mastery of cold is something we take for granted, whether it s air conditioning and frozen food or the liquefied gases and superconductivity at the heart of cutting-edge technology. But what is cold? How do you achieve it, and how cold can it get? This two-part NOVA special brings the history of this frosty fascination to life with brilliant dramatic recreations of high moments in low-temperature research and the quest for ever-lower notches on the thermometer. In the second hour, The Race For Absolute Zero dramatizes the titanic rivalry between Scottish researcher James Dewar and Dutch physicist Heike Onnes, who plunged cold science to the forbidding realm at which oxygen and then nitrogen turn into liquids. The race continues today as scientists pioneer super-fast computing near absolute zero the ultimate chill of -459.67° F where atoms slow to a virtual standstill.

Our mastery of cold is something we take for granted, whether it s air conditioning and frozen food or the liquefied gases and superconductivity at the heart of cutting-edge technology. But what is cold? How do you achieve it, and how cold can it get? This two-part NOVA special brings the history of this frosty fascination to life with brilliant dramatic recreations of high moments in low-temperature research and the quest for ever-lower notches on the thermometer.
The first hour, The Conquest of Cold, opens in the 1600s when the nature of cold and heat was a complete mystery. Were they different aspects of the same phenomenon? The experiments that settled these questions helped stoke the Industrial Revolution.
Tập 10
For 25 centuries the Parthenon has been shot at, set on fire, rocked by earthquakes, looted for its sculptures, almost destroyed by explosion, and disfigured by well-meaning renovations. It has gone from temple, to church, to mosque, to munitions dump. What could be next? How about a scientific search for the secrets of its incomparable beauty and astonishingly rapid construction? With unprecedented access, NOVA unravels the architectural and engineering mysteries of this celebrated ancient temple.

In the early 1950s, epic battles unfolded in the skies over North Korea as American and Russian fighters faced off in history's first jet war. This program explores the Korean War's aerial tactics, technology, and grim aftermath for downed pilots, many of whom disappeared without a trace.
The Korean War pitted the two most advanced fighters of their day, the American F-86 Sabre and the Soviet MiG-15, in furious air battles in North Korea's notorious "MiG Alley." With the help of dramatic reconstructions, rare archival footage, and interviews with veteran American and Soviet pilots, NOVA puts viewers in the cockpit to experience the lethal split-second duels that erupted in MiG Alley.
Tập 11
Millions remember the countdowns, launchings, splashdowns, and parades as the U.S. raced the USSR to the moon in the 1960s. But few know that both countries also ran parallel space programs, whose covert goal was to launch military astronauts on spying missions. With investigative journalist James Bamford, NOVA delves into the untold story of this top-secret space race, which might easily have turned into a shooting war in orbit.
Tập 6
The Mofu people of northern Cameroon have a close relationship with insects, in particular, the red driver ants which they use to combat termites.
Tập 12
At a research site in Fongoli, Senegal, a female chimpanzee breaks off a branch, chews the end to make it sharp, and then uses this rudimentary spear to skewer a tasty bush baby hiding inside a hollow tree. It’s an astonishing breakthrough for primate researchers—the first time anyone has documented a chimpanzee wielding a carefully prepared, preplanned weapon. But it's only the latest in a slew of extraordinary new findings about ape behavior.
The more researchers learn about the great apes—chimpanzees, bonobos, gorillas, and orangutans—the more evidence they find of creative intelligence. What, then, is the essential difference between them and us? "Ape Genius," a NOVA-National Geographic special, explores that provocative question and examines research that is illuminating the ape mind. Bit by bit, investigators are finding an explanation for why the non-human great apes never made the breakthrough into a human-style culture that builds on the achievements of previous generations.

Using courtroom reenactments based on transcripts and interviews with those present, NOVA looks at the events of the federal case of Kitzmiller v. Dover School District.
Tập 13
A look at the 2002 discovery of a four-winged crow-sized dinosaur fossil dubbed Microraptor, which has rekindled the scientific debate over the origins of flight. Included is a wind tunnel test of a "flight-ready" model of the 130 million-year-old Microraptor.
Tập 4
On October 4, 1957, the Space Age dawned with the red hue of the Communist flag when the Soviet Union launched the first artificial satellite. Sputnik I stunned the world and spurred a surge in science education and innovation that changed our world forever. But was Sputnik I really a shock to America's leaders, and how close was the U.S. to getting into space first? NOVA draws on previously classified documents to tell the real story behind the opening chapter in the space race.
Tập 14
The ancient Maya civilization of Central America left behind an intricate and mysterious hieroglyphic script, carved on monuments, painted on pottery, and drawn in handmade bark-paper books. For centuries, scholars considered it too complex ever to understand—until recently, when an ingenious series of breakthroughs finally cracked the code and unleashed a torrent of new insights into the Mayas' turbulent past. For the first time, NOVA presents the epic inside story of how the decoding was done—traveling to the remote jungles of southern Mexico and Central America to investigate how the code was broken and what Maya writings now reveal.

Can anyone run a marathon? How do you run 26.2 miles if you have trouble making it around the block? With good coaching, discipline, and lots of group support, as NOVA shows when it follows 13 generally sedentary people through a training regimen designed to prepare them for an ultimate test of stamina and endurance. Produced in cooperation with the Boston Athletic Association®, which granted NOVA unprecedented access to the 111th Boston Marathon®, and Tufts University, "Marathon Challenge" takes viewers on a unique adventure inside the human body, tracking the physiological changes that exercise can bring about.
