Melvyn Bragg and guests discuss the philosophy of love. With Professor Roger Scruton, author of many books including Sexual Desire; Angie Hobbes, lecturer in philosophy at Warwick University; Thomas Docherty, Professor of English at the University of Kent.
When I returned to this Engineering Department from the USA in 1984 my wife and I bought an historic and wonderful house some ten miles south of Cambridge. It was built around 1520, a date that could be substantiated to within a decade by the form of the oak beams that comprised its floors and ceilings. These had been shaped by iron blades that only lasted about ten years. Being someone of the present rather than the past I had not previously been much preoccupied with history but living in the splendid oak structure - like a fine sailing vessel that had gone aground - inspired me to wonder what had preoccupied the technologists and scientists of that age...
When the 33 Chilean miners emerged from underground before a worldwide audience of over a billion, they made a pact not to speak about what had happened underground. Now six of them remember the untold story of the first 17 days - when no-one outside knew if they were alive.
What is it that defines us? Stephen argues that above all, it is the way we speak. Be it a national language, a regional dialect or even class variation - we interpret and define ourselves through our language.
This programme looks at the ways language is used and abused. While not everyone approves of \'bad\' language, Stephen learns that swearing plays an important part in human communication the world over.
Dr Alice Roberts asks one of the great questions about our species: are we still evolving? Alice follows a trail of clues from ancient human bones, to studies of remarkable people living in the most inhospitable parts of the planet, to the frontiers of genetic research to discover if we are still evolving - and where we might be heading.
Horizon investigates evidence of human sacrifice practised by the Incas. Three mummified remains of humans have been found in the Andes and this programme follows anthropologist Johan Reinhard's search for more proof on the peak of Sara Sara in the Andes
We are bad at making decisions. According to science, our decisions are based on oversimplification, laziness and prejudice. And that's assuming that we haven't already been hijacked by our surroundings or led astray by our subconscious!
Featuring exclusive footage of experiments that show how our choices can be confounded by temperature, warped by post-rationalisation and even manipulated by the future, Horizon presents a guide to better decision making, and introduces you to Mathematician Garth Sundem, who is convinced that conclusions can best be reached using simple maths and a pencil!
Every day you make thousands of decisions, big and small, and behind all them is a powerful battle in your mind, pitting intuition against logic.Horizon uncovers the truth about how you really make decisions.
Dr Alice Roberts travels the globe to discover the incredible story of how humans left Africa to colonise the world - overcoming hostile terrain, extreme weather and other species of human. She pieces together precious fragments of bone, stone and new DNA evidence and discovers how this journey changed these African ancestors into the people of today.
Alice travels to Africa in search of the birthplace of the first people. They were so few in number and so vulnerable that today they would probably be considered an endangered species. So what allowed them to survive at all? The Bushmen of the Kalahari have some answers - the unique design of the human body made them efficient hunters and the ancient click language of the Bushmen points to an early ability to organise and plan.
Humans survived there, but Africa was to all intents and purposes a sealed continent. So how and by what route did humans make it out of Africa? Astonishing genetic evidence reveals that everyone alive today who is not African descends from just one successful, tiny group which left the continent in a single crossing, an event that may have happened around 70 thousand years ago. But how did they do it? Alice goes searching for clues in the remote Arabian Desert.
