Discovery Channel - Sunrise Earth International - Cloudforest Waterfall [docupedia]

http://forums.mvgroup.org/release.images/hukumuzuku/snapshot20090109152134.jpg

La Paz River, Vara Blanca, Costa Rica — The crater lake of the Poas Volcano drains from 9,000 feet into this high altitude cloudforest ravine. Stepping downward through a series of five waterfalls, we descend as the sun rises. Rays of light catch suspended water particles from the falling water, as green threads of life cling to sodden cliff walls. From within its pupa, an owl butterfly emerges with the increasing warmth of day, pumping fluid into its silken wings. Through the last rock opening, the water and sun burst out and down towards a restful pool, the famous La Paz waterfall.

Discovery Channel - Africa's Super 7 [docupedia]


"The good, the bad and the ugly, the teacher, the lover, the fighter and the strong, silent type! Stars of a tense 24-hour drama with birth, death and everything in between."


On the northern bank of the Sand River in the Mala-Mala Game Reserve in South Africa, seven magnificent creatures reside in an area the size of Manhattan Island. Tracking them for 24 hours we reveal the invisible threads that bind them together in a never-ending daily drama. This action-packed film will show how seven individual stories become one, how the animals move in and out of one another’s lives in the course of a single day. Sometimes their encounters happen just by chance, at other times they are intent on stalking each other down. In all cases whenever they meet the encounter is always riveting.

Each animal has different strengths, even some weaknesses, but seeing them in action is always impressive. Tracking them through one day and one night we witness their dealings with the neighbours from hell, staking their territory, stalking the same prey, risking their lives and cautiously interacting with or avoiding each other. This is a privileged and rare glimpse into the complex lives of Africa’s Super Seven.

Each species has its own vital role to play in this unfolding 24-hour drama. There is no room for the weak and in the African bush there’s only one rule: the biggest, strongest, fastest and smartest survive.

As amazing as these animals are, they all have their Achilles heel too, and occasionally our story includes a fight for survival for them just like any other creature of the untamed African wild. For Africa’s Super Seven there are no free lunches. Some will pay the ultimate price and some will even be lunch. Not for the faint hearted, this is a story of power, trust, hunger, desperation and elation – an unforgettable adventure.

BBC Earth ~The Climate Wars


Global warming, and how to combat it, has provoked intense debate, changed the way we see the planet and created headlines around the world. But when and how did scientists first discover global warming, why has it led to such furious debate and who should we believe?

In BBC Two's three-part series, Earth – The Climate Wars, geologist Dr Iain Stewart (Earth – The Power Of The Planet) presents a definitive guide to the history of climate change

Part 1: Battle Begins
In the 1970s the world seemed to be falling apart. From acid rain to overpopulation, ecological concerns were at the fore. And it was at this time that climate change first became a hot political issue. But it wasn't global warming that frightened scientists, it was the complete opposite; a new ice age.

Dr Iain Stewart traces the history of climate change from its very beginning and examines just how the scientific community managed to get it so very wrong back in the Seventies. Along the way he uncovers some of the great unsung heroes of climate change science, and introduces us to a secret organisation of American government scientists, known as Jason, who wrote the first official report on global warming as far back as 1979.

He shows how - by the late 1980s - global warming had already become a serious political issue. It looked as if the world was uniting to take action. But it turned out to be a false dawn. Because in the 1990s global warming would be transformed into one of the biggest scientific controversies of our age.

Part 2: Fightback
Dr Iain Stewart investigates the counter-attack that was launched by the global warming sceptics in the 1990s.

At the start of the '90s it seemed the world was united. At the Rio Earth summit the world signed up to a programme of action to start tackling climate change. Even George Bush was there. But the consensus didn't last.

Iain examines the scientific arguments that developed as the global warming sceptics took on the climate change consensus. The sceptics attacked almost everything that scientists held to be true. They argued that the planet wasn't warming up, that even if it was it was nothing unusual, and certainly whatever was happening to the climate was nothing to do with human emissions of greenhouse gases.

Iain interviews some of the key global warming sceptics, and discovers how their positions have changed over time.

Part 3: Fight for the Future
Having explained the science behind global warming, and addressed the arguments of the climate change sceptics earlier in the series, Dr Iain Stewart concludes the series by looking at the biggest challenge now facing climate scientists - Just how can they predict exactly what changes global warming will bring?

It's a journey that takes him from early attempts to model the climate system with dishpans, to supercomputers, and to the frontline of climate research today: Greenland. Most worryingly he discovers that scientists are becoming increasingly concerned that their models are actually underestimating the speed of changes already underway.

BBC - The Day the Universe Changed


The Day the Universe Changed (the 10-part series) is one of the best teaching tools available today for making students aware of the great ebb and flow of ideas that have gone into the development of Western thought. Host James Burke gives a stunning overview of this evolution of thought since the days of the Greeks in this ten-part series co-produced by BBC-TV and RKO Pictures.

Episode 1 - The Way We Are

Written and presented by James Burke, this 10-part series traces the development of Western thought through its major transformations since the days of ancient Greece. Program one is an overview of the series, showing how a culture's view of the world around it determines how it sees itself, and is reflected even in the smallest de tails of its customs and habits.

Episode 2 - In the Light of the Above

Relates that in the course of overrunning Moorish Spain, Christian Europe discovered libraries, universities, optics, mechanics, and natural philosophy. This rediscovery of classical knowledge led to the founding of universities and the replacement of Augustinian philosophies by Aristotelian theories.

Episode 3 - Point of View

Shows that Western Europe's rediscovery of perspective through the study of Arab optics led to revolutions in art and architecture. The West's new-found ability to control things at a distance resulted in new methods of warfare and the confidence to make long voyages of exploration.

Episode 4 - A Matter of Fact

Observes that the invention of printing and the advent of cheap paper forever transformed the nature of knowledge from the local and traditional to the systematic and testable. Nationalism, public relations, and propaganda are among the results.

Episode 5 - Infinitely Reasonable

Notes that investigators such as Copernicus, Kepler, Galileo, and Newton evolved better explanations of natural phenomena than those of Aristotle. Highlights the theories that led to a new conception of how the universe works and of man's place in it.

Episode 6 - Credit Where It's Due

Locates the origins of contemporary consumerism in the English industrial Revolution, powered by religious dissenters barred from all activities except trade. The invention of the steam engine, new forms of credit, surplus wealth, and opening markets laid the foundation for industrial society.

Episode 7 - What the Doctor Ordered

Traces modern society's recognition of the value of statistics to medical advances stemming from responses to the French Revolution and an English cholera epidemic. Identifies the origins of medicine as a science with the discovery of anesthesia, antiseptics, and bacteriology.

Episode 8 - Fit to Rule

Tracks the expectation of change, fundamental to contemporary society, through the developing sciences of botany, geology, and biology to Darwin's theory of evolution. Darwin's theory, in turn, has been used as a justification for Nazism, communism, and cut-throat capitalism.

Episode 9 - Making Waves

Points out that studies of the properties of magnetism, electricity, and light have led scientists to the realization that Newtonian physics is inadequate to explain all that they observe. The public, meanwhile, has continued to concentrate on the technological by-products of science.

Episode 10 - Worlds Without End

Observes that over the centuries Western civilization has regularly shifted its conception of the nature of truth. Citing the example of Nepalese Buddhism, a system as complete and satisfactory of Nepal as science is for the West, the series ends with a plea for tolerance.

Journey To The Edge Of The Universe


Using one single, unbroken shot, Journey to the Edge of the Universe explores what we would find if we were able to travel the entire length of our universe. Venturing past Neil Armstrong’s footsteps still sealed on the moon, the special soars over brightly illuminated Venus onto Mercury, a small planet made almost entirely of iron that may perhaps be the left-over remnants of a much larger planet.

Mars is a planet of extremes: with tornadoes, volcanoes and canyons unlike anything seen on Earth while Jupiter’s ever-present red storm is three times the size of Earth and has lasted for hundreds of years. Reaching the Saturn moon Titan, we find a landscape closely resembling Earth, but Titan’s rivers, lakes and oceans are not made of water, but of liquid methane. Could life exist here?

Travelling more than 90 trillion kilometres from Earth, viewers step inside the Epsilon Eridani star system where spectacular rings of dust and ice resemble the formation of our own solar system 4.5 billion years ago. Even further out is star Gliese 581, about the same age as our sun with a planet that is just the right distance to possibly support life.

Passing by the Pillars of Creation, viewers can see deep inside these clouds where huge stars being born, bringing light and perhaps even life to the universe.

Journey to 10000 BC


10,000 B.C. was a time of cataclysmic change on Earth. Extreme climactic fluctuations hurled the planet into a minor ice age; megafauna like the saber-toothed tiger and woolly mammoth were suddenly becoming extinct; and early humans began to inhabit North America. Cold and hungry, their fragile communities undertook perilous hunting expeditions. The slaughter of a single mammoth, weighing nearly ten tons, could be the difference between survival and death.

JOURNEY TO 10,000 B.C. brings this unique and thrilling period to life, and investigates the geologic and climate changes that scientists are just beginning to understand. In a major forensic investigation, HISTORY visits early human archaeological sites to uncover fossilized bones, ancient dwellings, and stone weapons, and uses state-of-the-art CGI to recreate the treacherous mammoth hunts and the devastating impact of a comet colliding with Earth.

Nature's Fury


Information

The savage fury of nature is vividly profiled in this video from National Geographic. Focusing on earthquakes, tornadoes, hurricanes, and floods--including the San Francisco quakes of 1906 and 1989 and Hurricane Andrew, which ravaged southern Florida in 1992--the production features terrifying footage shot during natural disasters as well as interviews filmed with survivors. Film shot from helicopters provides startling looks at the scale of devastation resulting from these disasters, but this documentary goes beyond looking at just the immediate effects of catastrophes. Personal stories of preparation, survival, and cleanup put a human face on nature's wrath. Solid scientific information is provided throughout, with computer graphics, for instance, demonstrating how the Mississippi floods formed in 1993. An explanation of Doppler radar and a visit with researchers who are attempting to predict earthquakes provide insight into the cutting edge of science. But it's the raw human drama in the video that steals the show. A climactic scene of a heavy-equipment operator risking his life while driving his bucket loader out onto a Mississippi River levee in a futile effort to stop the river from breaking through is more exciting than anything Hollywood could devise. --Robert J. McNamara

Battle at Kruger


Information

Caught on Safari: Battle at Kruger

An amazing tournament of animal survival at a South African watering hole is captured on a vacation video. Enlisting the help of wildlife experts, National Geographic deconstructs this battle.

Lions and Buffalo and Crocs, oh my!

For those of you who aren't part of the 29 million people who have watched this breathtaking, and surprisingly well-taped Youtube video, this is your chance. Even if you watch with one hand over your eyes, that's fine, just make sure you can peek through your fingers.

I can't say enough about NGC's 45 minute insight into this video. Don't get me wrong, the eight minute video, shown as the conclusion, is the highlight of the show, but there is a nicely fleshed out back story with lots of information thrown in, including a step-by-step breakdown of the video.


As one who had not previously viewed the Youtube video, the anticipation quietly built as I watched the program. At times I found myself pitying, and rooting for, a young African Buffalo, being fought over between a Pride of Lions and a Crocodile. Then my own hypocrisy caught up with me, (Did I have a burger for lunch?), and I started to feel for the hungry, inexperienced Lions.

My emotional tug-of-war didn't last long as the herd of African Buffalo stormed back to try and rescue their young. The conclusion shows one especially heroic Buffalo that inspires the herd in an attempt to scatter the Lions.

It is truly amazing to see animals in the wild, whom are believed to be inferior to humans, act more emotional and heroic than some of us. Maybe this is where our army came up with the idea that no one gets left behind.

I recommend watching this program for a more enhanced and detailed viewing of the battle at Kruger.

Ape Genius


Information

Original PBS Broadcast Date: February 19, 2008

At a research site in Fongoli, Senegal, a female chimpanzee breaks off a branch, chews the end to make it sharp, then uses this rudimentary spear to skewer a tasty bushbaby hiding inside a hollow tree. The footage represents an astonishing breakthrough for primate researchers: It's 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 (see Our Family Tree)—the more evidence they find of creative intelligence. What, then, is the essential difference between us and them? "Ape Genius," a NOVA-National Geographic special, explores that provocative question and examines research that is illuminating the ape mind.

The spear-wielding chimps were documented by anthropologist Jill Pruetz of Iowa State University, who also observed the Fongoli colony doing something else never documented before: holding a pool party. Chimps were long thought to be afraid of water, but as charming poolside footage reveals, these hairy bathers swing from the trees and take the plunge in high spirits.

In addition to Pruetz, "Ape Genius" features contributions by other noted researchers, including Brian Hare of Duke University, Andrew Whiten of the University of St. Andrews, Tetsuro Matsuzawa of Kyoto University, Rebecca Saxe of the Massachusetts Institute of Technology, and Josep Call and Michael Tomasello of the Max Planck Institute for Evolutionary Anthropology. (For an extended interview with Rebecca Saxe, see The Ape That Teaches.)

Bit by bit, these investigators are converging on an explanation for why the non-human great apes never made the breakthrough into an accelerating human-style culture that builds on the achievements of previous generations. After all, apes are stronger and more agile than we are. They have also shown previously unsuspected talents for reasoning, creative problem solving, and other intelligent traits. Some have even demonstrated rudimentary language abilities (see Kanzi the Bonobo). And their emotional lives seem on a par with ours, as is evident in moving footage of a mother chimp dealing with the sickness and death of her child.

But something has held them back. What?
