The blind watchmaker

The Blind Watchmaker: Why the evidence of evolution reveals a universe without design. One of the most famous arguments of the creationist theory of the universe is the eighteeth-century theologian Willam Paley’s: Just as a watch is too complicated and too functional to have sprung into existence by accident, so too must all living things, with their far greater complexity, be purposefully designed. But as Richard Dawkins, professor of zoology at Oxford University, demonstrates in this brillent and eloquent riposte to the Argument from Design, the analogy is false. Natural selection, the unconscious, automatic, blind yet essentially non-random process that Darwin discovered, has no purpose in mind. If it can be said to play the role of watchmaker in nature, it is the blind watchmaker.

Oxford professor Richard Dawkins has helped steer evolutionary science into the 21st century, and his concept of the “meme” contextualized the spread of ideas in the information age. In recent years, his devastating critique of religion has made him a leading figure in the New Atheism.

Richard Dawkins

Richard Dawkins, professor of the public understanding of science at Oxford University, is the author of The Selfish Gene, The Blind Watchmaker, The Extended Phenotype, River Out of Eden, and Climbing Mount Improbable and The root of all evil. As an evolutionary biologist, Richard Dawkins has broadened our understanding of the genetic origin of our species; as a popular author, he has helped lay readers understand complex scientific concepts. He’s best-known for the ideas laid out in his landmark book The Selfish Gene and fleshed out in The Extended Phenotype: the rather radical notion that Darwinian selection happens not at the level of the individual, but at the level of our DNA. The implication: We evolved for only one purpose — to serve our genes.

Of perhaps equal importance is Dawkins’ concept of the meme, which he defines as a self-replicating unit of culture — an idea, a chain letter, a catchy tune, an urban legend — which is passed person-to-person, its longevity based on its ability to lodge in the brain and inspire transmission to others. Introduced in The Selfish Gene in 1976, the concept of memes has itself proven highly contagious, inspiring countless accounts and explanations of idea propagation in the information age.

In recent years, Dawkins has become outspoken in his atheism, coining the word “bright” (as an alternate to atheist), and encouraging fellow non-believers to stand up and be identified. His controversial, confrontational 2002 TED talk was a seminal moment for the New Atheism, as was the publication of his 2006 book, The God Delusion, a bestselling critique of religion that championed atheism and promoted scientific principles over creationism and intelligent design.

“Dawkins … is a master of scientific exposition and synthesis. When it comes to his own specialty, evolutionary biology, there is none better.”
Jim Holt, The New York Times

Fall of the Mongol hordes

(video hosted on Guba )

700 years ago the world was dominated by one superpower… the Mongol Empire. Only one conquest still eluded their leader, Khubilai Khan – the mystical islands of Japan. To seal his place in history, he constructed the biggest invasion force the world has ever seen – a fleet of more than 4,400 ships. But at this pivotal moment in world-history the fleet vanished without a trace… What force destroyed the Mongol armada? Was it the legendary Japanese samurai? Human error? Or a natural disaster of catastrophic proportions? Now a Japanese marine archaeologist believes he has found the Mongol fleet. With an array of the latest marine forensic technology, he is revealing chilling new insights into the events of that fateful day. Can science finally solve the mystery of the Lost Fleet of Khubilai Khan?

Don’t miss the bizarre-looking Tibetan fox, captured on film for the first time. Over six weeks the team follow a pride of 30 lions as they attempt to hunt elephants. Using the latest night vision equipment, the crew film the chaotic battles that ensue at close quarters.

The mars underground

(Note: Video hosted on VEOH.)

Join us on a journey, the daring first human mission to the red planet and explore the challenges of surviving on Mars, a mysterious world that once had oceans, rivers and may have harbored simple life – the discovery of which could revolutionize our understanding of the universe. Ever since the beginning of the space age, a number of scientists and engineers have dreamed of someday making that journey a reality.

One of the most outspoken of these is Dr. Robert Zubrin, a maverick aerospace-engineer and author known as the “Christopher Columbus of Mars”. For years, Zubrin has been designing and promoting a humans-to-Mars expedition, not as venture for the far future or one that will cost us impossible billions, but as a goal that could be attained within ten years. He sees continuing expeditions to Mars eventually leading to colonization and a second home for humanity through a process known as “terraforming” – turning Mars into a viable blue planet.

Shot entirely in breathtaking High Definition, THE MARS UNDERGROUND is a landmark documentary that brings to life Zubrin’s vision through state-of-the-art 3D animation, and gives us a glimpses into the future of man’s reign on Mars.

A world without water

The world is running out of its most precious resource. True Vision’s timely film tells of the personal tragedies behind the mounting privatisation of water supplies. More than a billion people across the globe don’t have access to safe water. Every day 3900 children die as a result of insufficient or unclean water supplies. The situation can only get worse as water gets evermore scarce. For much of the world, atlases no longer tell the truth. Today, dozens of the planet’s greatest rivers run dry long before they reach the sea. They include the Nile in Egypt; the Yellow River in China; the Indus in Pakistan; the Rio Grande and Colorado in the US; the ancient Oxus that once poured into the Aral Sea in Central Asia; the Murray in Australia and the Jordan in the Middle East, which is emptied before it can even reach the country that bears its name. The dire state of such rivers is the most visible sign of a profound crisis in how the world uses its water – a crisis that reflects water’s new place as one of the most important and threatened commodities. It’s a situation that could herald a world in which wars are fought over water.
