On Start the Week Andrew Marr asks whether scientists have failed in their task to communicate their work to the wider public. The 'passionate rationalist' Richard Dawkins has spent his career trying to illuminate the wonders of nature and challenge what he calls faulty logic. But he wonders whether Darwin would consider his legacy now with 'a mixture of exhilaration and exasperation'. The child psychologist Deborah Kelemen has been working with young children to find out what they make of adaptation and evolution with the storybook, How the Piloses Evolved Skinny Noses, and is encouraged by the sophistication of their understanding. The mathematician Cathy O'Neil says it's time people became more aware of the mathematical models and algorithms that dominate everything we do online and in finance, and yet are increasingly opaque, unregulated and left unchallenged. While Alex Bellos looks to improve numeracy with puzzles and brainteasers which have been entertaining and frustrating people for centuries. Producer: Katy Hickman.

On Start the Week Tom Sutcliffe talks to the former Conservative MP and last Governor of Hong Kong, Chris Patten, on the eve of the 20th anniversary of the handover of Hong Kong from Britain to China. In a candid memoir Patten looks back at his political life. He lost his seat in the 1992 election, despite the Sun newspaper claiming the Tory landslide with the headline, "It's The Sun Wot Won It". James Graham's new play goes back to the birth of this ruthless 'red top' tabloid, when a young and rebellious Rupert Murdoch burst on to Fleet Street, to launch a newspaper devoted to giving the people what they want. Fleet Street is no more and following this month's general election some critics have questioned the continuing influence of the mainstream media. Kerry-Anne Mendoza is the Editor-in-chief of the left-wing political blog, The Canary, and believes new forms of media online are disrupting the status quo in the UK. Baroness Tessa Blackstone was regarded as a kaftaned radical in the 1970s by the Whitehall establishment when she was part of a review of Central Policy which challenged the very workings of Britain's powerful diplomatic corps.

On Start the Week Andrew Marr explores killer diseases and the health of the world. Kathryn Lougheed focuses on one of the smartest killers humanity has ever faced - TB. It's been around since the start of civilisation and has learnt how to adapt to different environments, so today more than one million people still die of the disease every year. As with many diseases it's the poor who are most at risk. But Sir Michael Marmot explains how it's not just those at the bottom who are adversely affected, as health and life expectancy are directly related to where you are on the socio-economic ladder. The psychiatrist Lynne Jones also explores how far mental well-being is connected to human rights and the social and political worlds in which we live. She trained in one of Britain's last asylums and has travelled the world treating traumatised soldiers and civilians. Professor John Powell is interested in how far the digital world can help improve health and access to health care - from interventions for heart attacks to the treatment of depression. There are more than two hundred thousand health apps on the internet, but just how effective are they?Producer: Katy Hickman.

On Start the Week Kirsty Wark asks what it is to be a man, and to belong to a tribe. Thomas Page McBee has sought answers as he's transitioned from female to male, and explored how far the violent men of his youth are models of masculinity. Fatherhood and aggression take centre stage in Gary Owen's play, Killology, in which he's created a video game that allows players to live out their darkest fantasies. The poet Kayo Chingonyi moved to Britain when he was a child and in his debut collection he translates the rites of passage of his native Zambia to his new home. In the TV drama Ackley Bridge, filmmaker Penny Woolcock imagines a new school that throws together two communities, segregated along ethnic lines, in a fictional Yorkshire mill town.

On Start the Week, Andrew Marr explores where truth ends and invention begins in the story of the self. The theatre director Robert Lepage has spent decades creating other worlds on stage; now his one-man show recreates his childhood home in 1960s Quebec, with truth at the mercy of memory. Rebecca Stott has written the story of her family that her father left unfinished, including the Christian cult that inspired their devotion, until doubt led them astray. Miranda Doyle casts doubt on the veracity of memoir itself, by writing a series of lies to get at the truth of her family story. Andrew O'Hagan has examined three lives existing more fully online than offline: the Wikileaks founder Julian Assange; the fabled inventor of Bitcoin, Satoshi Nakamoto and 'Ronald Pinn'- an experiment in identity theft that disrupts the very notion of the self.

On Start the Week Andrew Marr discusses India. The Indian MP Shashi Tharoor looks back at the history of the Raj in Inglorious Empire, a searing indictment of the British and the impact on his country. The journalist Adam Roberts travels from Kerala to the Himalayas to find out whether a resurgent, vibrant India is about to realise its potential, and whether the belief in future prosperity will cover over the cracks which have divided the nation in the past. The Prime Minister, Narendra Modi, is at the centre of India's reinvention, and has galvanised Hindu nationalists, but the academic Kate Sullivan de Estrada argues that he's a controversial figure both at home and abroad. And the writer Preti Taneja retells Shakespeare's great tragedy, King Lear, set in Delhi and Kashmir, in her exploration of contemporary Indian society.

On Start the Week Amol Rajan seeks the truth in a post-truth world. The political columnist Matthew D'Ancona paints a dystopian picture in which trust has evaporated, conspiracy theories thrive, and feelings trump fact. He argues that the very foundations of democracy are under threat. Claire Wardle is hoping her organisation First Draft will equip users to verify the sources of stories and tackle misinformation online. But what happens when the peddlers of misinformation are state-sponsored? The Chinese writer Lijia Zhang spent a decade working in a rocket factory and her memoir, Socialism is Great!, reflects the great social transformation in China since the 1980s, and the shifts in trust and truth which mirrored such changes. The writer China Miéville, who is best known for his stories of urban surrealism, turns his attention to the story of the Russian Revolution. Producer: Kirsty McQuire.

On Start the Week Andrew Marr talks to the writer and performer Kate Tempest about her desire to bring out the epic in everyday lives, and to show the poetry in lived experience. Tracy Chevalier has taken the themes of Shakespeare's Othello and transported them to a US elementary school, while Hanif Kureishi mines the dark world of jealousy and revenge in his latest novel. Lewis Hyde looks back to mythical mischief makers from Hermes to Loki to celebrate modern day rule breakers as the shapers of culture.

On Start the Week Andrew Marr talks to the American writer, poet and farmer Wendell Berry. In his latest collection of essays, The World-Ending Fire, Berry speaks out against the degradation of the earth and the violence and greed of unbridled consumerism, while evoking the awe he feels as he walks the land in his native Kentucky. His challenge to the false call of progress and the American Dream is echoed in the writing of Paul Kingsnorth, whose book Confessions of a Recovering Environmentalist eschews the grand narrative of a global green movement to focus on what matters - the small plot of land beneath his feet. Kate Raworth calls herself a renegade economist and, like Berry and Kingsnorth, challenges orthodox thinking, as she points to new ways to understand the global economy which take into consideration human prosperity and ecological sustainability.Producer: Katy HickmanImage: Wendell Berry Photographer: James Baker Hall.
