Adventures in 2D: Graphene and Beyond20150801

Adventures in 2D: Graphene and Beyond20150801

Top graphene researchers, including the Nobel laureate who first isolated pure graphene, talk to Bridget Kendall about the future of not just this 'wonder-material' but also a whole host of other 2-dimensional crystals now available. How close are we to a cheap production of quality graphene on an industrial scale? Can the EU's Graphene Flagship, a research and industrial consortium which includes about 150 partners in over 20 countries, quickly move graphene products from the lab to the consumer? And should we worry about the safety of 2D materials? Recorded at Graphene Week held at the University of Manchester, with Sir Konstantin Novoselov, Sarah Haigh, Jari Kinaret, Toby Heys and Jonathan Coleman.

Aftermath20120922

Bridget Kendall presents an ideas discussion show in which some of the world's most eminent minds tackle the big questions of our age.

Aliens20141011

Scientists have now detected far-away planets that may contain life, but what makes some people believe in extra-terrestrial beings, and not others? What really lies behind stories of alien abduction or alien invasion? And how much damage do alien species of plants actually cause? Bridget Kendall asks ecologist Chris Thomas, science-fiction writer Nnedi Okorafor and psychologist Richard McNally.

Being Cold20160102

Does the experience of coping with bitter cold affect the way people think and feel? And what happens to culture and identity when climate begins to change? To explore these questions the Forum this week comes from Canada, one of the world's most northern countries, with some 40 % of it in the Arctic. Joining Bridget Kendall are Nobel-nominated Inuit activist and former International Chair of the Inuit Circumpolar Council Sheila Watt-Cloutier, Arctic spatial ecologist David Atkinson and "Ice Huts" architectural photographer Richard Johnson. Recorded in the auditorium of the National Gallery of Canada, Ottawa, as part of the Spur Festival of Ideas.(Photo: Ice Hut #530 by Richard Johnson. Joussard, Lesser Slave Lake, Alberta, 2011).

Bubbles20140920

Fragile gas filled spheres, sparkling champagne globules that fill your nose with fizz, pipe dreams that pop when the illusion grows too big: Bridget Kendall explores the mysterious world of bubbles with physicist Helen Czerski, biomedical engineer Constantin Coussios and artist Bradley Hart who makes giant paintings using bubble wrap.

Clay20150808

It is one of Earth's oldest building materials, a natural seal against water, useful for paper making, medicine and lots of other things. Bridget Kendall and guests discuss clay. Why it is so useful, why so many cultures treasure it but why it can also be a source of serious ill health. Chinese-American writer Huan Hsu explains the importance of porcelain in China, Irish ceramic artist Claire Curneen introduces us to the powerful visual language of clay, and British geologist Tim Jones studies a particular type of clay which causes a debilitating illness affecting millions of people in the developing world.(Photo: Guardian by Claire Curneen.

Controlling Our Health20120929

How much control do we really have over our bodies and our health? Modern technology and medicine can treat conditions that were once thought to be incurable. But in other ways, are we any less vulnerable than in the past to disease and injury, both as individuals and societies? On the ideas discussion programme, Bridget Kendall's guests bring personal as well as professional experience to the table: Mark Harrison is a medical historian who's tracked the links between disease and commerce. Frank Reynolds has devoted the last 20 years to developing treatments for his own spinal cord injury. And the award-winning author MJ Hyland explains why she's gone public about her life with multiple sclerosis.

Born in London, MJ Hyland spent her childhood between Ireland and Australia. She is now a lecturer in creative writing at Manchester University and an award-winning novelist. She was diagnosed with multiple sclerosis in 2008 but kept it a secret for four years as she came to terms with her condition and the loss of control that it meant.

After a car accident left him with a traumatic spinal injury, American Frank Reynolds was living in almost constant pain, his body bound in a knee-to-neck body cast, flat on his back in a small Philadelphia condominium. Today, he is not only walking but heading a pioneering start-up at MIT that is developing novel technologies for spinal and other neurological injuries. He explains the ideas behind his twenty-year quest to control his body again.

And Mark Harrison contributes his knowledge as Professor of the History of Medicine at Oxford University. He studies how to control the spread of infectious diseases between groups of people and across the world.

Core: A Journey To The Centre Of The Things20151226

How startling discoveries about the core of the earth and the oldest star yet known help us understand our place in the grand scheme of things. Tim Marlow and the astrophysicist Arif Babul, the astronomer Anna Frebel and the earth scientist Paul Savage go on a quest to find the core or centre.(Photo: a split Earth showing a molten core).

Counterfeiting20140419

Counterfeiting

This week, we're taking a look at counterfeiting. How do you spot a forgery in the art market? How can you tell if a medicine is a useless or even harmful fake which might make your illness even worse? Bridget Kendall is joined by Ghanaian anti-counterfeiting entrepreneur Bright Simons; art auctioneer and author of Breakfast at Sotheby's - An A-Z of the Art World Philip Hook; and art historian Winnie Wong whose new book Van Gogh on Demand takes us on a trip to China, to a village where every year millions of copies of well-known oil paintings are churned out to be distributed for sale in around the world.

Crystals20130831

Bridget Kendall discusses the incredibly varied uses and meanings of crystals with cave scientist Penny Boston, whose work takes her deep underground to study ancient life forms trapped inside the earth's largest crystals; biophysicist Elspeth Garman who, with the help of robots, can spend years growing one perfect protein crystal in her lab; and artist Roger Hiorns who has encrusted many objects with sparkling blue copper sulphate crystals, including the entire interior of a derelict London bedsit.

Death20120804

Is there a right way to face our own death? Bridget Kendall and guests discuss.

Bridget Kendall's guests consider the best way to think about our own death. What is the best way to prepare for it?

After a life as a literary editor, Diana Athill has become well known for her frank and eloquent memoirs and thoughts on her impending death. Now at the age of 94, she has come to relish life in an old people's home.

Pauline Chen has to deal with life and death in her daily work as a liver transplant and cancer surgeon. She thinks doctors could benefit from thinking more about the way we handle death and the emotional impact it has on the patient's family. She has written about the subject both as a book and as an online column for the New York Times.

And the poet Paul Muldoon from Northern Ireland shares his personal experiences of dealing with the death of his sister, as well, as his latest work based on the verses of The Bible's Book of Lamentations.

Deja Vu20151003

Is déjà vu a brain glitch, something triggered by the broader environment or a more mystical phenomenon? Bridget Kendall talks to cognitive neuropsychologist Chris Moulin, cognitive psychologist Anne Cleary and Nigerian born novelist and academic Chigozie Obioma, who was recently shortlisted for the Man Booker Prize.

Democracy and the Arts in South Africa20140823

Democracy and the Arts in South Africa20140823

Twenty years on from the end of apartheid, what role can the arts play now in helping South African society develop? Recorded with an audience at the National Arts Festival in Grahamstown, Bridget Kendall talks to playwright Mike Van Graan, poet Phillippa Yaa de Villiers, arts journalist Percy Mabandu, and jazz singer Nomfundo Xaluva who performs live for us.

Design And Beauty20151114

How far can we stretch the notion of a beautiful design? And, how fundamental is it to the world around us and our search for the answers to life's mysteries? We delight in beauty when we find it in the design of everyday objects. It's incorporated in the bodies we are born with and the ways we enhance them. And, on a cosmic scale, there is beauty in the rules which govern the universe. Bridget Kendall is joined by nobel prize winning physicist Frank Wilczek, furniture designer Khalid Shafar and body architect Lucy McRae to explore the frontiers of what beauty in design can mean.

Disgust20130105

There's quite a lot of agreement between people on just what is disgusting and it usually involves some pretty basic body fluids. In this week's episode of the ideas discussion programme, Bridget Kendall rolls up her sleeves and delves a little deeper into this fundamental human emotion, one which stems from a basic instinct to keep ourselves alive.

We hear from surgeon Iain Hutchison how disgust is a subjective response, from sensory scientist John Prescott how even rats dislike bitter food, and from psychologist David Pizarro how our level of squeamishness can even reveal our politics.

Dust And Ash20130921

We can see it moving around, but we cannot stop its track. It's in our houses and places of work as well as in the atmosphere. And although we try to avoid it, it can keep the planet a little cooler. We discuss dust and ash. Joining Bridget Kendall are: Japanese-American writer Katie Kitamura, whose latest novel was inspired by volcanic ash travelling across boundaries; Xenia Nikolskaya, a Russian photographer who has captured images of deserted palaces and mansions in Egypt that are covered in dust; and Professor Charlie Bristow, a sedimentologist from Birkbeck College at the University of London, who has worked in the dustiest place on earth - the Bodélé basin in the Sahara - and has been examining why dust travels the Atlantic to nourish the Amazon rainforest.

Fragility20130824

Why are some materials and ecosystems easier to break than others? And what gives others better resilience? Joining Bridget Kendall are the celebrated American novelist Barbara Kingsolver, whose latest novel contemplates vulnerability in butterflies and humans; one of world's leading experts on bumblebees, professor David Goulson, who explains why artificially rearing bumblebee nests can paradoxically lead to mass extinction; and Markus Buehler, bio-engineer from the Massachusetts Institute of Technology, who studies the molecular basis of strength and weakness in natural materials such as human bones and spider's webs.

Hair, Fur and Cilia20140802

Hair, Fur and Cilia20140802

Hair has always held us captive: a symbol of strength and vitality, or of sexual attraction and youth. But what are its molecular secrets? And what are we learning about those other mysterious filaments, the hair-like cilia strands attached to almost every living cell?

Bridget Kendall brings together three people whose work explores why these slender threads are essential to life. The medical geneticist Philip Beales explains why cilia disorders can affect memory and learning, Professor Ralf Paus, a leading hair loss researcher, reveals fresh insights into the role of neurohormones in promoting hair growth, and the artist Adeline de Monseignat shows her beautiful but disturbing sculptures, which suggest hair and fur aren't really a stack of dead cells, but somehow still alive.

Hands20140104

Hands20140104

Some say that the hand is where the mind meets the world. So what happens if you lose a hand? What are the options for a replacement? Are we focusing too much on the hands' ability to grip and hold and overlooking their sensitivity to heat and cold, to smooth or rough surfaces? And the power of the human hand to create music out of chaos: how does a conductor communicate with an orchestra, to get its individual members to play as one and translate his vision into a compelling performance?

Bridget Kendall's guests are: prof. Simon Kay, a surgeon based in Leeds, who performed the first hand transplant in the UK; New Zealander Lynette Jones, Senior Research Scientist at Massachusetts Institute of Technology, who studies tactile sensations; and Sakari Oramo, a Finnish musician who recently became the Chief Conductor of the BBC Symphony Orchestra. Duration: 44 minutes

Ice20131228

When photographer Camille Seaman stood on the Ross Ice Shelf in Antarctica, she felt dizzy. It was 200 feet down to the sea, and below sea level was another 800 to 1,000 feet of ice. And all this, she thought, was made by one snowflake falling on another, through time.

On The Forum, Bridget Kendall finds out more about the ice masses of the polar ice caps. Along with Native American artist Camille Seaman, she is joined by the Danish glaciologist Poul Christoffersen, who's been measuring the effects of a warming ocean on that very ice shelf, and American engineer Mary Albert who drills down into ancient snow cores for crucial climate clues.

Imagination20150829

Imagination20150829

What happens in our brains when we are using our imagination? What role does imagination play in our decisions to visit foreign countries or even to migrate there? And is there something that makes people from a particular place, say India, use their imagination in a unique way? Bridget Kendall talks to neuroscientist Peter Tse, poet Arundhathi Subramaniam and anthropologist Noel Salazar.(Photo: The human brain. Credit: AFP/Getty Images).

Lines20150103

Our world seems to be bound and criss-crossed by lines: except that when you look closely, many of them do not exist in reality, only in your mind. So what are we to make of lines: a useful human abstraction, to help us make sense of the world? And what does a line mean to an artist, whether one who wields a paintbrush or pencil, or one who fashions words into poetic verse? Joining Bridget Kendall are social anthropology professor Timothy Ingold, poet and graphic artist Imtiaz Dharker and distinguished South African artist William Kentridge.

Machine Translation: The End Of The Human Translator?20160604

Translating from one language to another is fraught with difficulty - capturing exact words can be hard enough let alone more subtle meanings like metaphor, pathos, or culturally specific references and phrases. But machine translation is even more complex, although it is developing at a very rapid pace and both text and voice can now be translated very quickly. Bridget Kendall and guests explore whether machine translation means an end to human translators and what impact it might have on our desire and ability to learn and immerse ourselves in other languages.

Memory20120825

What are memories and what role do they play? Bridget Kendall and guests discuss.

Exploring the mysterious realm of memory, Bridget Kendall discusses with her three guests how and why memories are formed, and what impact they have.

Dorothy Bohm is one of Britain's most important documentary photographers of the twentieth century. Now aged 88, she sees her photos as a way of capturing time and holding it.

So what is memory? Raymond Tallis is a professor of geriatric medicine and a former researcher in clinical neuroscience, who now writes about science from a philosophical point of view. He says that memory is a profoundly mysterious experience and it is impossible to give a neurological account of how memories are formed.

The Russian-born writer and broadcaster Zinovy Zinik contributes some memories of his own, including his experience of unravelling his family history, which formed the backbone of his most recent book, "History Thieves".

Mental Health20120818

One in three of us will be affected by mental illness at some time during our lifetime. It can take various forms from the most common - depression, to psychotic illness. Kendall's guests explore the way mental illness is viewed and treated around the world, and what can be done to help.

The Indian psychiatrist Vikram Patel is at the forefront of a campaign to promote global mental health. His non-governmental organization in Goa pioneers ways to treat mental health problems in places with few resources, a theme he has also written about in his book "Where There's No Psychiatrist".

Matthew Johnstone is an artist and writer based in Sydney. He first experienced depression in his mid-20s and he describes how he tried to cover it up so he could continue his successful advertising career. In his bestselling illustrated book "I Had a Black Dog", Johnstone used the character of a black Labrador to communicate his experience. He now works part-time as the Creative Director of the Black Dog Institute in Australia.

Gwen Adshead is a forensic psychiatrist and psychotherapist at Broadmoor, Britain's highest security institution for offenders with mental disorders, well known in Britain because it's where the country's most notorious killers are sent if the court declares them "criminally insane'. She believes that learning to tell your own story is the key to getting to grips with all sorts of mental illness, even for her patients.

Global ideas on tackling mental illness, in a discussion led by Bridget Kendall.

Modern Alchemy20140222

We look at some of the most ingenious ways in which entrepreneurs and scientists are turning useless junk into precious gold, or at least extracting the elements we can go on using.

Joining Bridget Kendall are:

South African Professor of Chemical Engineering Alison Lewis, who's developed a new technique which can freeze contaminated water, and recover both pure water and the so-called 'toxins' as usable products.

Dr Angela Murray's project Roads to Riches retrieves microscopic amounts of platinum group metals - lost from cars' catalytic converters - from road dust, then uses bacteria to convert them back into catalyst, for example for hydrogen fuel cells.

Journalist Adam Minter's book Junkyard Planet reveals how the billion-dollar global recycling trade works. From his vantage point in China, he says that even the worst, dirtiest recycling is still better than the very best mining.

Multilingualism20140927

How is the brain affected by juggling between different languages and how does this affect identity? And what is the impact on a child's development if they speak one language at home and another at school? Bridget Kendall talks to poet and cultural critic Gustavo Perez Firmat, developmental linguistics researcher Antonella Sorace, and cognitive development specialist Ellen Bialystok.

Natural Navigation20141227

Could you find your way around using only natural signs? Bridget Kendall explores the phenomenal computational power of the human brain to work out where we are and the navigational ability of migratory birds to fly thousands of miles. With behavioural ecologist Tim Birkhead, navigator and explorer Tristan Gooley and neuroscientist Jennifer Groh.

Night20120811

Three specialists in the dark hours take Bridget Kendall on a trip through the night.

First, the Oxford Professor of Circadian Rhythms, Russell Foster, who thinks that our biological clock, which measures the 24-hour cycle, is embedded in our genes, making night shift work particularly challenging.

The German photographer Rut Blees Luxemburg refuses to keep regular hours and takes most of her photos at night, using a long exposure to find colour in the dark.

And giving some context, the historian Craig Koslovsky, from the University of Illinois, traces how the people of early modern Europe first took over the night by illuminating the streets and their buildings, enabling them to eat, drink, work and socialise in very different ways.

Bridget Kendall and her three guests enter the night.

Plant And Flower Shapes20130223

What makes flowers so beautiful? Why are some leaves curly, others spiky, and others flat? Bridget Kendall brings together a panel of three experts who have some answers to nature's mysteries.

Enrico Coen is a professor of plant genetics who has been running computer simulations of how plant cells turn from bud to bloom. He's found some simple rules of nature and, joining forces with Rob Kessler, professor of ceramics at St Martins Art School London, and PhD student Tilly Eldridge, used them to create some original "organic" objects of his own at his lab at the John Innes Centre in Norwich.

Andrew Zuckerman is a photographer from New York who's got up close and personal with some of the world's most wonderful flowers in his quest to capture the essence of a flower's shape in a single photograph, shot against a plain, white background.

And ecology professor Lars Chittka helps us understand nature through the eyes of a bee, that much-coveted pollinator, which is attracted to a flower by symmetry, colour and scent. An expert in the relationships between plants and other creatures, Professor Chittka founded the Research Centre for Psychology at Queen Mary, University of London.

Plasticity20150822

Isn't it remarkable that everyday objects, especially those made from modern plastics, can bend, squash, stretch, and generally 'shape-shift' in a number of ways? So how is that possible? Bridget Kendall and guests consider plasticity from several viewpoints: Aurora Robson is an artist who works with plastic garbage, Sujata Kundu a nanochemist who analyses plasticity at the level of atoms and electrons, and Takao Hensch a neuroscientist investigating whether it's possible to recreate youth-like plasticity in an adult brain.(Photo: The Great Indoors: art installation by Aurora Robson).

Resurrection20150815

Why we yearn to bring the past back to life, whether it is extinct animals, ancient languages or salvaging the wreckage of a legendary speedboat. Bridget Kendall asks the ancient DNA biologist Beth Shapiro, the Sanskrit expert Jyotsna Kalavar and the engineer Bill Smith to share their thoughts.(Photo: A woolly mammoth. Credit: Getty Images).

Revenge20121006

Conflicts around the world remind us daily of the perils of taking an eye for an eye. How deep does the instinct for revenge lie? Can victims of personal trauma find closure by other means? And how does a society overcome a shared sense of injustice?

On the ideas discussion programme, Bridget Kendall is joined by the celebrated novelist Rose Tremain, the Indian essayist Salil Tripathi and the activist Yvette Alberdingk Thijm.

Rose Tremain turns her thoughts to the quality of revenge - a trait missing from her creation, the doctor Robert Merivel. He appears in her latest novel, Merivel: A Man of His Time, which is the sequel to the highly-acclaimed Restoration about the doctor's rise and fall in Charles II's England of the late 1600s.

The Indian writer Salil Tripathi is currently writing a book about the crimes committed during Bangladesh's war of independence in 1971, and the way in which its survivors dealt with its violent aftermath.

And the activist Yvette Alberdingk Thijm talks about her work as executive director of Witness, a human rights organisation which helps victims from all over the world tell their stories by using video technology.

Second Chances20130928

Bridget Kendall and guests discuss the idea of re-visiting a place, reviving old friendships and learning to walk again. For over thirty years, photographer Nick Danziger has made a point of returning to his subjects in troubled places from Afghanistan to Bosnia. He explains what makes his second visit so different from the first one. Works by the Chinese-American author Gish Jen prompt the question: do whole countries, as well as individual people, deserve another bite of the cherry? And Californian inventor Van Phillips reveals the inspiration behind his revolutionary artificial leg design which has given a new lease of life to both himself and countless other amputees world-wide. Illustration by Emily Kasriel

Self-assembly20150404

Bridget Kendal and guests explore the amazing world of 'Self Assembly'. Cells working together to build a human embryo, a swarm of bees, robots joining forces to explore challenging terrain. These are all examples of self assembly - the coming together of simple units to form something of great complexity. Bridget is joined by experimental biologist Jamie Davies, chemical engineer and physicist Sharon Glotzer and robotics engineer Roderich Gross.

Jamie Davies is Professor of Experimental Anatomy at the University of Edinburgh. He unravels the processes by which a fertilised human egg is able to develop into an embryo without any external input. He also talks about using cellular self assembly to grow kidneys in the laboratory.

Roderich Gross is Senior Lecturer in Robotics and Computational Intelligence at the University of Sheffield. He uses small, simple robots - 'swarmbots' - to work together without an overall blueprint to carry out a variety of tasks. Their behaviour is modelled on the swarm intelligence which can be observed in the natural world - flocks of birds, swarms of bees, shoals of fish etc.

Sharon Glotzer is Professor of Chemical Engineering at University of Michigan College of Engineering. Her work with nanoparticles and molecules uses self assembly to create new materials with properties such as the ability to change shape or colour. She also envisages using the technology to store data not on hard drives, but in clusters of particles suspended in liquid.

Shells20150905

Mankind has long been attracted to beautiful shells, but what are the many other secrets that link them to our human fate? Bridget Kendall asks the marine scientist Anne Cohen, the archaeologist Josephine Joordens and the cultural historian Toby Green to share their thoughts.(Photo: A man holds a conch shell.

Silence20130810

Joining Bridget Kendall to be noisy about silence are American conservationist John Francis, who chose to stop talking one day and didn't speak again for seventeen years; Russian ice artist and explorer Galya Morrell, who has found that silence is an essential tool for survival in the North; and award-winning historian Diarmaid MacCulloch, who is interested in the tension between speech and silence that has existed throughout Christian history.

Solitude20140816

Do you crave being on your own, having time to take stock and think things through? Or do you loathe being alone and always try to be around other people? Joining Bridget Kendall to explore solitude are New Zealand novelist Eleanor Catton, New York educator Diana Senechal and Chinese-American writer Yiyun Li.

The Forum In Beijing: Digital China20131116

Bridget Kendall chairs a wide-ranging discussion in Beijing about the internet in China: with nearly 600 million Chinese now online, how is the spread of social media changing the nature of their society? How much is free expression really curtailed by the Great Firewall of China and the recent legislation aimed at curbing the spread of 'rumours' on the net? And is the ability to share the minutiae of their lives online making the young in China politically apathetic? Photo credit: Jackie Zhang

Does the explosion of social media in China empower the individual or the state?

The Hidden Kingdom Of Fungi20130803

Put any prejudices about poisonous toadstools and mould in damp corners out of your mind: this week's Forum explores fungi as an extraordinarily tough and ecologically friendly building substance that could reshape our world. Plus the hundreds of thousands of species of fungi that have yet to be named and studied: some of them may hold vital clues on how to cure diseases or solve environmental problems. Bridget Kendall is joined by fungal ecologist Lynne Boddy, Danish mycologist and photographer Jens Petersen, and San Francisco-based artist, chef and fungal furniture-maker, Phil Ross.

The Hidden Power of Noise20160409

Bridget Kendall and guests explore the unseen and often un-noticed power which noise has over us. With writer Garret Keizer who is interested in the social and economic dimensions of noise; sound artist Jana Winderen who records sounds made by underwater creatures; and Cambridge Professor of English Steven Connor who focuses on the 'ums, ahs, ohs, and ahems', expressive language noises that are often dismissed as marginal or trivial.

The Hidden Power of Noise20160409

The Power Of Expectation20140531

How good are you at blind tasting? Could you tell if you sipped three different cups of coffee which was the best quality without seeing the price? And if you were given a pill to cure a headache - do you think it would help, regardless of whether it was real medicine or not? The Swedish neuroscientist Predrag Petrovic asks if a doctor's expectations can affect the success of a patient's treatment, the Indian neuro-economist Baba Shiv explains why consumers expect something to be better if they pay more, and the American musicologist Elizabeth Hellmuth Margulis on why our enjoyment of music is determined by what we're expecting to hear.

The Power Of Technology20120901

Does digital technology open or close our minds? A show from the Aspen Festival of Ideas.

As digital technology gets ever more integrated into our lives we present a special edition of The Forum from the Aspen Festival of Ideas in the USA. What effect does digital technology have on how we think, live and learn? Should we worry about creating virtual echo chambers where we only hear what we want? Or should we celebrate the increased interconnectivity the internet brings? Bridget Kendall's guests bring very different perspectives to bear:

Joi Ito is the Director of the MIT media lab and a leading writer on innovation, global technology policy, and the role of the internet in transforming society in substantial and positive ways. He believes that the internet enables decentralized innovation, a type of openness which in turn is shaping approaches in science and education.

Mike Gallagher is president and CEO of the Entertainment Software Association (ESA), the trade association representing U.S. computer and video game publishers. He argues that we can achieve connectedness and empathy through game play and that playing digital games are another way of forming communities.

We also hear from Julie Taymor, a filmmaker and the innovative theatre director who turned the animated film The Lion King into a big theatrical hit. She cautions us about the limiting power of two dimensional screens.

The Power of Wind20160402

Wind is all around us on earth and in a different form, out in space; a powerful force which shapes our environment and which increasingly, we are trying to tame and harness.

With Bridget Kendall to explore some aspects of wind, Dr. Max Platzer, the distinguished aerospace engineer, once involved in Nasa's iconic space launches, who is now focused on how to harvest energy from the powerful winds of the world's oceans using a massive fleet of sailing ships with the ability to convert wind energy into hydrogen.

Earth and space meteorologist Professor Chris Scott from Reading University in the UK, who tracks the solar winds which come to us from space to probe how they affect us on earth and who has new research linking wind with lightening.

And from Boston in the USA, artist Nathalie Miebach, who weaves extraordinary sculptures out of storm data she takes from weather stations.

The Real And The Virtual20121229

Digital technology has given us a new realm to operate in, but is the border between the real and the virtual becoming increasingly blurred? And what's the role of maths in helping us to make sense of things, both real and virtual?

In this episode of the ideas discussion programme, Bridget Kendall brings together three people whose work takes them close to the dividing line of the tangible and intangible worlds. From Jerusalem, the Israeli digital innovator Eyal Gever uses 3D imaging software to create stunning models of simulated catastrophes, from Boston the American professor Robert Kaplan explores the way that maths gives expression to virtual ideas, and in the studio the British ceramicist Edmund de Waal describes his love of hand-crafted, physical objects and how they connect people through time.

The Vanishing World Of Our Ancestors20130406

The ways of our ancestors are still alive in many parts of the world and they can teach us a thing or two. A child in New Guinea could rival a child in New York for their ability to negotiate with adults, for example. But there are drawbacks too - particularly for the elderly or the weak.

Bridget Kendall is given a tour of a vanishing world by three experts who have explored the boundaries of modern and traditional societies in places as far apart as New Guinea, Zanzibar and Sikkim.

Polymath Jared Diamond is Professor of Geography at UCLA. He's been visiting the remote tropical island of New Guinea for the past fifty years. He says that the tribal way of life there, for all its problems, provides unique insights that could serve us modern humans well.

Prajwal Parajuly is a writer from Sikkim, a small Indian state high up in the Himalayan mountains, on the borders of Nepal, Tibet and Bhutan. It's a part of the world with lots of ethnic diversity and ancient traditions and in his short stories, Prajwal explores the ambiguous role traditions play in people's lives.

Rhodes University anthropologist Rose Boswell is originally from the island of Mauritius. She has studied women's traditions on other Indian Ocean islands, especially Zanzibar and Madagascar. She tells us what makes the inhabitants of Zanzibar remain faithful to traditional birthing rituals, while people elsewhere adapt a more Western way of life.

Time To Rethink What Is 'normal'?20140830

Where is the dividing line between 'being a bit different' and having a mental illness that needs treatment and professional help? Bridget Kendall is joined by novelist Jerry Pinto, who has turned personal experiences of growing up with a relative with bipolar disorder into an award-winning book, Professor of Disability and Human Development Lennard Davis, and autism research pioneer Professor Uta Frith.

Tracking And Surveillance20131005

Bridget Kendall and guests explore the shadowy world of tracking and surveillance. As the ability of technology to monitor our online behaviour and even our physical movements in the workplace increases, how far should we be prepared to compromise privacy in the interests of security and efficiency? And how can the same technology be employed to better track endangered species? Finnish cyber-security expert Mikko Hypponen, Kenyan vulture scientist Munir Virani, and Australian political geographer Anja Kanngieser give their views. Photo: A satellite navigation system.

Upside Down20150926

Bridget Kendall and her guests step into a world turned upside down. Inverted buildings are a passion of structural engineer Hanif Kara, cabaret artist Fez Faanana subverts gender stereotypes in his entertaining and subversive show and Dr. Kirsty Park explains why bats spend so much of their lives hanging from their toes.

Wheel Revolutions20160618

People have come up with the idea of the wheel many times and in different places, but what were the key turning points which led to mass transport and the miracle of modern logistics? Bridget Kendall discusses the still-unfolding story of the wheel with historian Richard Bulliet, logistics expert Jagjit Singh Srai and Cyr wheel dancer Valerie Inertie.

Worlds In Miniature20151010

In an ever-expanding world, why do so many of us favour the brevity of a tweet or Facebook post and find scaled down miniature models magical and appealing? Jeff Nunokawa is a literature professor who loves long 19th century novels but reaches out to his students in bite sized posts. Slinkachu is an artist whose miniature figurines could be hidden in a street nearby, waiting for you to stoop down and enter their tiny world. Plus, a salutatory reminder that small is not always better from clinical geneticist Usha Kini who has pioneered research into microcephaly, a medical condition where disrupted growth means smaller than normal heads and brains.

Zooming Out20140426

It is easy to be hoodwinked into thinking the world you see and experience is the most important part of reality. This week you are invited to leave the perspective of earth and zoom out into space to discover what can be seen from thousands of miles away. Joining Bridget Kendall for the journey are space archaeologist Sarah Parcak, artist Mishka Henner, and cosmologist Max Tegmark. (Photo: Planet Earth from space courtesy of Nasa/ Getty images)
