Historian and leather and kink activist Vi Johnson likes to be called Mama Vi. At 75, within her community, she’s become a fiercely protective figure, looking after not only the people who make it what it is, but also its culture and history. As a leader of a community that has long existed at the margins, she has witnessed many attempts to erase its history; some obvious, others far more insidious. Driven by ignorance, by hate, or even by the impulse to hide parts of themselves. For our 100th episode of Sideways, Matthew Syed asks how a community survives when the evidence of its existence is threatened? From book burnings to records quietly discarded, the past is shaped not only by what we choose to remember, but by what we allow to disappear. With activist Vi Johnson; Richard Ovenden, Director of the Bodleian Libraries at the University of Oxford and author of Burning the Books: A History of Knowledge Under Attack. And sexologist Toni Solenne.

It’s a cold morning in Euston Station in London and professional violinist Min Kym is about to get on a train to Manchester to play a concert. With her is her 300 year old, £1.2 million Stradivarius, one of the most valuable and precious types of violin in the world. More than that, this is Min’s Strad - it fits just right for her, it’s her constant companion across the world, it’s a relationship, a love. Until… it disappears.

Matthew Syed considers what we value and why.

At some point in our lives, all of us will face difficult news. That was the case for Canadian academic Kate Bowler. She was diagnosed with stage four colon cancer, at just 35. When the news hits, the support she receives is overwhelmingly positive. But as well intentioned as those responses are, Kate becomes trapped in a role she doesn’t want to play.

Matthew Syed asks why we reach for positivity so quickly in the face of suffering and where that instinct comes from.

With contributions from Kate Bowler; Dr Stephanie Alice Baker, Professor of Sociology at City St George's, University of London and social psychologist Pr Batja Mesquita, from Leuven University.

Matthew Syed follows the extraordinary journey of a French scientist who found signs of learning, problem-solving and remembering - in a blob of slime. Not the Ghostbusters kind, but in a slime mould. It's a single celled, brainless organism that has become a bit of a star in France for its unexpected capabilities.

In this episode, Matthew considers the intelligence that lies in unexpected places, beyond the confines of a brain.

With contributions from Audrey Dussutour (Research Director at the French National Centre for Scientific Research, CNRS), Dr. Pamela Lyon (Independent Researcher and Adjunct Senior Lecturer at the University of Adelaide), and Dr. Michael Levin (Vannevar Bush Distinguished Professor of Biology and Biomedical Engineering at Tufts University and faculty member at the Wyss Institute at Harvard.)

Rob Broderick aka ‘Abandoman’ grew up surrounded by classic comedies like Laurel and Hardy, and with a teacher mother who inspired his fascination with wordplay. When Rob discovers freestyle rap as a teenager, all these influences coalesce to inspire him to step into the world of stand up comedy.

Only Rob doesn’t want to hone a rigid ‘tight ten’ of material. In fact, Rob doesn’t want to prepare anything at all - he steps out on stage and improvises everything - no script whatsoever.

Matthew Syed uncovers the remarkable neurological processes that take place when we improvise and allow our inner critic to take a back seat.

With contributions from hip-hop musical comedian Rob Broderick (Abandoman); Professor Charles Limb, Chief of Otology, Neurotology and Skull Base Surgery at the University of California, San Francisco; Professor Keith Sawyer, creativity researcher based at the University of North Carolina at Chapel Hill; and George Lewis, composer, technologist, musicologist and professor of music at Columbia University.

David McGurk had a childhood love of action figures. Something that he and Matthew Syed, and probably most of us, share. But David and his brother went a step further - they started making their own makeshift figures from soap and cheap glue.

But it wasn’t until family tragedy struck as an adult that the memory of his brother’s creativity returned and inspired David to become a professional miniature figure-maker, with a quirky eye for his subject matter.

From miniature busts of emperors, to the mystery of tiny canoes in the British Museum, Matthew Syed uncovers the big messages and emotions that can be distilled in the tiniest of objects.

With contributions from artist David McGurk; Jack Davy, anthropologist and a curator at the Natural History Museum in London; and Lambros Malafouris, Professor of Cognitive and Anthropological Archaeology at the University of Oxford.

From a very young age, Holly Mathieson showed remarkable ability at the piano. With the support of her concert pianist grandmother, she nurtured a rare talent for music, and later explored ballet and choral singing as well. A path toward excellence in classical music opened before her and, for nearly 20 years, she followed it diligently as an internationally renowned conductor.

But when the COVID-19 pandemic hit in 2020, she realised it was time to reclaim a life that had been defined by her abilities rather than by her choices.

Matthew Syed, himself a national table tennis champion at just age 10, explores our relationship with talent and the pressures - both internal and external - to fulfil it. Through Holly Mathieson’s story, he asks whether we own our talents or whether they own us. He considers why it is that gifted people are seldom allowed to walk away from their abilities without the accusation and condemnation that they are wasting their lives, remaining trapped by the idea that they owe it to the world to fulfil their potential.

With Holly Mathieson, psychologist and author Pippa Grange and Elizabeth Anderson, philosopher at the University of Michigan.

Almost twenty years ago, an armed man stormed a small Amish school in Pennsylvania. It was a horrific attack in which he shot at ten girls. He then turned the gun on himself. The attack claimed the lives of five young girls and severely injured five others, including one who remained profoundly disabled for the rest of her life, and died at the age of just 23. Within hours, the affected Amish community took the most extraordinary steps to extend compassion to the family of the gunman. And it set off a life-altering process for Marie, his wife.

Matthew Syed follows Marie’s inconceivable journey navigating the complexities of forgiveness. He delves into Amish theology to understand how forgiving is a frequently misunderstood discipline, embedded in the collective identity of the Amish community, and considers how their approach to forgiveness challenges conventional wisdom.

Matthew also hears from one of the foundational figures in forgiveness science on the tangled journey of forgiving oneself. This is something Marie found herself grappling with after going through a process of forgiving her husband for things she would never fully understand. It prompts Matthew to reflect on the quiet and rippling power inherent in the many acts of forgiveness that emerged from a day of unimaginable tragedy.

Featuring Marie Monville, speaker and author of the memoir One Light Still Shines: My Life Beyond the Shadow of the Amish Schoolhouse Shooting; Steven Nolt, Professor of History and Anabaptist Studies at Elizabethtown College, Pennsylvania, and co-author of Amish Grace: How Forgiveness Transcended Tragedy; and Everett Worthington, Professor Emeritus of Psychology at Virginia Commonwealth University and a leading researcher in the psychology of forgiveness.

A morning routine. A cup of tea brewing. Toast almost ready. It’s Monday, and a young man is getting ready to leave for work, when there’s a knock at the door. Two police officers stand outside with news that will change his life - he’s under arrest.

He’s stunned. There must be a mistake. What has he done? “I’m afraid we can’t share that information yet,” one of the officers says. He’s never been in trouble with the law. But now he is - and no one will tell him why.

Matthew Syed invites us to confront the absurd - the moments when life stops making sense, when there’s nothing to grasp or explain. He asks whether we have grown used to the absurdity woven into our lives and whether there is a way to push against it.

With author Michael Foley, Professor of Anthropology Nina Holm Vohnsen (University of Aarhus) and Mathijs Bal, Psychologist and Professor of Management (University of Lincoln).
