Growing Up in the Universe was a series of lectures given by Richard Dawkins as part of the Royal Institution Christmas Lectures, in which he discussed the evolution of life in the universe. The lectures were first broadcast in 1991, in the form of five one-hour episodes.To start off part one, Dawkins discusses the amazing capabilities of the human body and contrasts these with the limited cap
It is the frontline of the worlds most dangerous battle, a battle which involves the entire Earth. As the Amazon Rain Forest faces a crucial tipping point amidst the increase of illegal logging activities, deforestation rates have nearly doubled, there are nearly three football fields worth of forestation being cut down every minute.This being said it is the Brazilian indigenous people who are
On March 23, 1989, respected chemists, Dr. Stanley Pons and Dr. Martin Fleishman made an announcement that rocked the world of science. Their tabletop experiments with heavy water, a renewable resource readily available in ocean water, yielded enormous amounts of heat energy. Appropriately named, "Cold Fusion," this breakthrough challenged many basic scientific concepts. In response, a group of po
If it were up to the sun, we would have no energy problem. Every half hour on the Earth's surface, there is more than enough light to provide energy needs for the whole world in a year. We don't have an energy problem, we have a conversion problem. If we are able to harvest sunlight in smart way, then we can prevent a global energy crisis. That sounds nice but that does not mean it will succeed,
The film, produced by the brilliant and ecology-minded French director Luc Besson, is the work of acclaimed aerial photographer Yann Arthus-Bertrand, whose cinematography, covering landscapes in 54 countries, provides a journey you’ll never be able to experience anywhere else. Bertrand’s views of Earth from above are so powerfully exquisite they will bring you to tears.Nut, along with its enthra
Professors Iain Stewart and Professor Kathy Sykes take a timely look at global warming ahead of the Copenhagen summit, exploring the world’s leading climate scientists’ vision of the planet’s future.Scientists predict that if global temperatures continue to rise at their current rate, Earth will be one degree warmer within 10 years, two degrees warmer within the next 40 years and three degrees o
Can technology help us tame nature’s most violent tornadoes? Little on this earth can withstand the violent fury of an F5 tornado. A churning vortex with winds over 300 miles an hour, these tornadoes create immense swaths of death and destruction in a matter of seconds. But today, experts are exploring the supertwister’s complex inner workings in bold new ways in the hopes of one day being able to
The Ice Hotel of Sweden is the biggest hotel in the world that is built entirely by ice and snow. This hotel is the brainchild of two close friends who are specialized in Ice architecture, Arne Bergh and Ake Larsoon.Situated near the North Pole, the hotel covers and area of 6000 sq meters and requires 300 tons of ice to build. When completed, the hotel features a bar, church, main hall, receptio
