Presented by young poet Owen Sheers, this series looks at six poems that have affected him and the way the British people view their landscape.
Weighing in at up to 4 million times the mass of the Sun, the biggest super massive black holes have the power to rip planets apart and swallow entire stars. Their gravitational pull is so strong that nothing, not even light, can escape. And that's a problem for astronomers, because it means they're entirely invisible to any telescope. Despite these obvious obstacles, the program meets the astronomers attempting to image a black hole for the very first time and the theoretical physicists getting ever closer to unlocking their mysteries.
The drama of the plant world is impossible to view with the naked eye. But using the latest time-lapse technology, all is revealed: how a Venus flytrap snaps shut and imprisons its prey; how the animal-like grasping hooks of the cat's claw creeper and the sticky pads of the Boston ivy help in their fight for light.
A fascinating and spectacular insight into a unique pride of lions living in Botswana's Okavango Delta, the largest freshwater wetland in Africa. Through rare and thrilling footage witness lion behaviour as previously unseen, capturing these huge cats swimming skilfully in swamps to stalk water buffalo, executing dangerous nocturnal forays and tactically preparing for each hunt. Narrated by Jeremy Irons.
Bowling for Columbine is an alternately humorous and horrifying film about the United States. It is a film about the state of the Union, and the violent soul of America. Why do 11,000 people die in America each year at the hands of gun violence?
We've all heard of 'six degrees of separation', the idea that everyone in the world can be connected in just a few steps. But what if those steps don't just relate to people but also to viruses, neurons, proteins and even to fashion trends? What if this 'six degrees of separation' allowed us an insight into something at the core of Nature? We used to think the way in which web pages, power grids and people tied together was more or less random. But recently two young physicists independently discovered that fundamental laws govern networks. It's a discovery that may prove as important as Newton's observations of gravity or Darwin's theory of evolution.
The third and final part of the series on Joseph Stalin focuses on his desperately cruel and despotic rule. Stalin could tolerate no other leaders and systematically liquidated anyone he thought was a potential threat to his authority.
The first of a four-part series of the 'people's history' of post-war Australia draws on the stories and memories of ordinary Australians to reveal the significant social and cultural shifts here since 1945. (STUDY GUIDE AVAILABLE)
