Is an ancient charioteer the best paid sportsperson of all time?

Modern sport can seem awash with money, but it’s been claimed that the richest sportsperson of all is an ancient Roman Charioteer from the second century AD called Gaius Appuleius Diocles, with career winnings that stood at 35 million sesterces. One calculation has translated that into an astonishing $15 billion dollars today, and it’s a figure that’s stuck. But should we believe it? Duncan Weldon talks to ancient historian Professor Mary Beard from the University of Cambridge to learn more about the big business of chariot racing, and how we should think about money and wealth in the economies of the past.

Is this Premier League striker a secret maths genius?

Chelsea striker Liam Delap has recently stunned fans on Instagram by apparently doing incredibly complicated calculations in his head, finding what’s known as the cube root of some very large numbers. But is he really a human calculator? Or is there something else going on? Tim Harford speaks to Rob Eastaway, mathematician and author of ‘Maths on the Back of an Envelope’ to learn about the trick you can use to pull this off - and while he’s here we also ask him about the trend of more goals being scored in the Premier League.

Could Europe use its financial muscle to strong-arm the US?

Could European Nato members use their large holdings of US shares and bonds to put pressure on America? It’s a question that some in Europe found themselves asking as the geopolitical crisis over Greenland escalated and leaders desperately tried to think of ways to dissuade Donald Trump. It is true that trillions of dollars of American financial assets are held in Europe. But the devil, as ever, is in the detail. Tim Harford talks to Toby Nangle, a journalist with the Financial Times, to drill down into the numbers.

Is Greenland as big as Africa?

The vast island of Greenland has found itself at the centre of a geopolitical crisis. But a little bit of geography can help us see the situation in a new light. YouTuber and map expert Jay Foreman explains how Mercator maps - the maps that the vast majority of us use to understand the world - contain necessary but massive distortions and hugely exaggerate the size of the Arctic island. So, why is making a flat map of a round globe so difficult? Why did we end up with a problematic map in the first place? And are there any alternatives?

No, a study has not shown that the covid jab causes cancer

In Autumn 2025 a paper in South Korea was published that excited many a vaccine sceptic online. The paper claimed that receiving a vaccination against Covid19 was linked to a 27% increase in cancer risk. However, when you dig into the data there is no evidence that the vaccine caused the cancer. We spoke to Professor Justin Fendos to explain why we cannot take this type of statistical analysis at face value.

Have more than 100 private schools been forced to close because of VAT?

Tim Harford investigates some of the numbers in the news. This week: A headline in the Mail says more than 100 private schools have closed since Labour came to power and ended the VAT exemption for private schools. Is that number right? Is it true that when Covid hit the UK, a one-week delay in imposing lockdown led to 23,000 deaths? Do 10 million families rely on X as their main source of news? That’s what government spokesperson Baroness Ruth Anderson said in the House of Lords, but is it correct? s there really a “quiet revival” of Christian worship? Two YouGov polls found churchgoing had gone up by 50% between 2018 and 2024 in England and Wales. New polling data suggests otherwise.

NEW in The History Bureau - Putin and the Apartment Bombs In September 1999, just weeks after a 46-year-old Vladimir Putin became Prime Minister, four bombs blew up four apartment buildings across Russia, killing hundreds of people while they slept. The attacks plunged the country into panic. Families fled their homes. Residents patrolled their blocks around the clock. An entire nation paralyzed by fear. But who did it? It's a mystery that has fuelled some chilling theories. The government blamed Chechen militants. Many reporters agreed. But then the whispers started. Was something even more sinister going on? Over 25 years later, journalists who covered the bombings still can't agree on who planted the explosives or why. Presenter Helena Merriman returns to the story with the reporters who were there on the ground. What did they get right first time around? And, in the chaos and confusion of unfolding events, what did they miss? The History Bureau revisits the defining stories of our times with the reporters who first covered them.

HISTORIE
The comedy podcast that takes history seriously. In each episode of You’re Dead to Me from BBC Radio 4, Greg Jenner is joined by a comedian and an expert historian to learn and laugh about the past. History isn’t just about dates and textbooks – it’s about extraordinary characters, amazing stories, and some very questionable fashion choices. How long did it take to build an Egyptian pyramid? What does the Bayeux Tapestry reveal about medieval life? Why did it take nearly half a millennium for Joan of Arc to become a saint? And was Catherine the Great really all that great? Whether you want to explore ancient landmarks like Stonehenge and Machu Picchu, dance through the history of Broadway and Bollywood, or find out how the Tudors rose to power, Greg and his guests promise to teach you something new that you won’t have heard in history lessons. Previous episodes of You’re Dead To Me have covered everything from royals to revolutionaries, actors to activists and divas to dictators. Take a stroll through the history of high-heeled shoes or get the scoop on the history of ice cream. Maybe you’d like to paint like the cave artists of the Palaeolithic era, work out like a Victorian bodybuilder, or fight like a Spartan? We’ve even hosted a special, live episode with the BBC Concert Orchestra to explore the dramatic life of Wolfgang Amadeus Mozart. Whatever your historical interests, Greg and his guests make even the trickiest topics easy to follow. Join them for a history lesson that’s as entertaining as it is enlightening - with no homework required.
