Chilean author Benjamín Labatut shines a light on the ethics of science in a disturbing triptych tracing the path from the fundamentals of mathematics to the delusions of artificial intelligence. It focuses on John von Neumann, a titan of science and a Hungarian wunderkind with exceptional mathematical powers. He designed the world's first programmable computer, invented game theory, pioneered AI and helped create the atomic bombs that destroyed Hiroshima and Nagasaki. But when illness unmoored his mind, his work pushed further into areas beyond human control.

Blending fact and fiction, Labatut takes us to the frontiers of rational thought, where invention outpaces human understanding and leads us to the brink of Armageddon. He talks to Hay Festival President Stephen Fry about The Maniac, his first book in English.

The world of sport has a new opponent: climate change. A world championship marathon was recently held at midnight to avoid the blistering sun. Athletes needed oxygen tanks to play during wildfire season in California. Ski resorts in the Alps have turned into ghost towns. Golf courses are sinking into the sea. But with billions of participants and fans around the world who rely on the sector for entertainment, jobs, fitness and health, this is an industry we can’t afford to lose. Sport ecologist Madeleine Orr argues that there are ways to mitigate the worst elements of climate change. Through interviews with athletes, coaches and politicians in her book Warming Up: How Climate Change is Changing Sport, she describes how the sports world can fight back.In conversation with Claire Taylor, a World Cup-winning English cricketer, Chair of Cricket at the MCC and a management consultant.

Aged 15, Rebecca Achieng Ajulu-Bushell was world number one in the 50m breaststroke.

She made history, but chose to walk away from it all. Ajulu-Bushell shares how she achieved victory and what it cost her to do so, physically and mentally. Laying bare the pressures of success and meditating on Blackness and identity, Ajulu-Bushell is honest and heartfelt. Lahiri talks to Creative Producer Heather Marks.

Come for a wild swim in the Wye with adventure and wild swimming specialist Angela Jones.

Two experts on green capitalism discuss its limits and possibilities with Bronwyn Wake, Editor in Chief of Nature Climate Change. Rathi is an award-winning senior reporter for Bloomberg News and host of climate podcast Zero. In Climate Capitalism: Winning the Global Race to Zero Emissions he looks at stories that bring people, policy and technology together, suggesting that the green economy is not only possible, but profitable. Dr Ritchie is senior researcher in the Programme for Global Development at the University of Oxford, as well as deputy editor and lead researcher at the highly influential online publication Our World in Data, which brings together the latest data and research on the world’s largest problems and makes it accessible for a general audience. Her latest book is Not the End of the World: How We Can be the First Generation to Build a Sustainable Planet.

Artificial intelligence may be the most transformative technology of our time. As AI’s power grows, so does the need to figure out what – and who – this technology is really for. Drawing lessons from three 20th-century tech revolutions – the Space race, in vitro fertilisation and the internet – Verity Harding, a leading insider in technology and politics and director of the AI & Geopolitics Institute at the Bennett Institute for Public Policy at the University of Cambridge, rejects the dominant narrative that compares AI’s advent to the atomic bomb. She speaks to Dr Jonnie Penn, associate teaching professor of AI Ethics and Society at the University of Cambridge.

World-leading microbiome scientist and surgeon James Kinross shows us how everything from exercise, sleep and diet through to antibiotics and ageing are directly impacted by the state of our microbiome. He introduces us to the microbiome, a vast genetic universe of ‘dark matter’ – bacteria, yeasts, viruses and parasites – living inside us, which adapts with us as we age and influences how we think and feel, our sex lives and even how fast we run. Kinross is a senior lecturer in colorectal surgery and consultant surgeon at Imperial College London. He talks to neuroscientist Dr Hannah Critchlow.

Our panel discusses Wales’ global responsibility to tackle climate change, the effects of climate change on Wales’ population and what Wales can do to reach net zero by 2035.

Humankind may be rapidly approaching the commercial exploitation and perhaps colonisation of the moon and Mars. Does history give us confidence that it will be peaceful and constructive, instead of a further reason for conflict, trouble and wars? Given the precedents – humanity’s ‘common inheritance’ of such places as the Antarctic and the world’s oceans – we must ask: how well have we succeeded in avoiding international competition and conflicts? How well do international agreements work? The philosopher and Principal of Northeastern University, London, asks what should be done to avoid competition in space becoming conflict on Earth?

Growing plants, whether inside or outside, can foster feelings of happiness and bring people together. Community gardener and designer Tayshan Hayden-Smith and writer Alan Heeks discuss the importance of greenery of all kinds. Hayden-Smith’s Small Space Revolution: Planting Seeds of Change in Your Community sets out his blueprint for why we need to green more outdoor spaces and the practical steps we can all take to do so in our home or community. Heeks’ Natural Happiness shows how gardening methods like composting, mulching, and crop rotation can be used to cultivate human nature too.

The food production experts talk to science presenter Kate Humble. Could cultivated meat from stem-cells grown in a bioreactor beat climate change? Provide real meat but without the slaughter?

Ed Winters demonstrates How to Argue With a Meat Eater (and Win Every Time), explaining the principles of veganism as a way to create a more ethical, kind and sustainable world, and breaking down every argument used against it.

From the mystery of quantum physics all the way to the horrors of disruptions to world peace, we make the mistake of thinking in terms of individual entities. We forget that entities are made by their relations. Italian theoretical physicist and writer Carlo Rovelli suggests that trying to make sense of the world in terms of relations can help us make better sense of reality on all its levels.

The botanist draws on her expertise and experience as an indigenous woman to show how other living beings offer us gifts and lessons, even if we’ve forgotten how to hear their voices. Her subjects range from the Native American legend of the Skywoman to the language of wild strawberries and squash, asters and goldenrod, algae and sweetgrass. Her collection of essays weaves together traditional ecological knowledge and scientific knowledge to examine the relationship people have, and can have, with the living environment.
