Carlo Rovelli Live: Why Numbers Don’t Exist

Intelligence Squared

Show Notes

Carlo Rovelli is an award-winning theoretical physicist and writer with a gift for making complex ideas feel real and accessible. Whether exploring black holes, quantum mechanics, philosophy, or history, he inspires audiences with his sense of wonder and curiosity at how the world works.

Beloved by millions, Rovelli’s books, including Seven Brief Lessons on Physics and The Order of Time, invite us into the deepest corners of the universe, while challenging what we thought we knew about time and space.

In September 2026 he came to the Intelligence Squared stage to explore some of the most awe-inspiring discoveries of modern science, the subject of his new book, On The Equality of All Things. Drawing on both cutting-edge physics and ancient philosophy, he asked what these ideas reveal about the strangeness of reality. How does modern science impact age-old philosophical questions? What does it really mean to say that something exists? What is time, if it flows differently for different observers? And what kind of world do we inhabit if nature’s most fundamental elements are defined only by their connections?

Donald Trump’s growing accommodation of Vladimir Putin has raised a stark question: has the US abandoned Ukraine? Conor Boyle speaks to Michael McFaul, former US ambassador to Russia and author of Autocrats vs. Democrats, about what Trump’s approach means for Ukraine, America’s democratic identity and the future of the international order. They explore whether this rupture was years in the making, the roles of China and Elon Musk and whether a future administration could restore American leadership, or whether the country has changed for good.

Few figures in modern British politics have operated as close to the centre of power as Michael Gove. Over more than a decade in government, he has held some of the most senior offices of state – including Education Secretary, Justice Secretary and Secretary of State for Levelling Up, shaping policy across domestic reform, economic strategy and the future of the Union.

In England and Wales, the total fertility rate fell to 1.39 children per woman in 2025. More than half of the world’s countries and areas are now below the level at which a population replaces itself without migration. Yet those numbers cannot tell us whether people are freely choosing smaller families, struggling to find a partner, leaving parenthood too late or being priced out of the future they wanted.

A century later, his distant relative Oliver Cromwell helped defeat a king, establish a republic and became Lord Protector. Both men are usually remembered as exceptional commoners who rose through talent and ruthless pragmatism. But neither rose alone.
