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.

Does Venezuela really have the biggest oil reserves in the world?

When people think of oil rich nations their mind generally goes to Saudi Arabia, Iraq and the US. But according to international statistics, the country with the largest oil reserves is Venezuela, with 300 billion barrels worth. At their peak they produced over 3.5 million barrels of the stuff per day. However, due to lack of investment, sanctions and mismanagement that peak is long gone. Following their military intervention, the US administration claims they can get Venezuela's oil production up and running at full capacity within 18 months. But can they, and why is it that estimates for other countries oil reserves have fluctuated but Venezuela’s has stayed at 300 billion barrels for over two decades?

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.

HISTORIA
At 25, Hannah’s life begins falling apart. An anonymous intruder has made her phone her enemy. Aided by the technology we all rely on, this intruder is watching Hannah, threatening her, even pretending to be her. Feeling increasingly unsafe, Hannah goes to the police, but they can’t stop it. Worse, they don’t even recognise it for what it is: stalking. Hannah doesn’t know for sure who is behind it all, but she suspects an older man she met more than two years earlier at London Fashion Week. Initially, he claimed to have been hacked. Even today, he disputes stalking her. To make sense of what’s happening Hannah turns to a woman she’s known since she was seven years-old, and who also happens to be an investigative journalist. Together with her “ex-step mum” Carole Cadwalladr, they set out to piece together something the police couldn’t: the true identity of Hannah’s stalker. Doing so means untangling a web of deception spanning continents. On her suspected stalker’s trail, Hannah realises nothing about them is as she first thought.

POLITIK
Spanning history, religion, culture, science and philosophy, In Our Time from BBC Radio 4 is essential listening for the intellectually curious. In each episode, host Misha Glenny and expert guests explore the characters, events and discoveries that have shaped our world. History fans can learn about pivotal wars and societal upheavals, such as the rise and fall of Napoleon, the Sack of Rome in 1527, and the political intrigue of the Russian Revolution. Those fascinated by the lives of kings and queens can journey to Versailles to meet Marie Antoinette and Louis XIV the Sun King, or to Ancient Egypt to meet Cleopatra and Nefertiti. Or perhaps you're looking to explore the history of religion, from Buddhism's early teachings to the Protestant Reformation. If you're interested in the stories behind iconic works of art, music and literature, dive in to discussions on the artistic genius of Michelangelo's Sistine Chapel and Van Gogh's famous Sunflowers. From Gothic architecture to the works of Shakespeare, each episode of In Our Time offers new insight into humanity's cultural achievements. Those looking to enrich their scientific knowledge can hear episodes on black holes, the Periodic Table, and classical theories of gravity, motion, evolution and relativity. Learn how the discovery of penicillin revolutionised medicine, and how the death of stars can lead to the formation of new planets. Lovers of philosophy will find episodes on the big issues that define existence, from free will and ethics, to liberty and justice. In what ways did celebrated philosophers such as Mary Wollstonecraft and Karl Marx push forward radical new ideas? How has the concept of karma evolved from the ancient Sanskrit texts of Hinduism to today? What was Plato's concept of an ideal republic, and how did he explore this through the legend of the lost city of Atlantis? In Our Time celebrates the pursuit of knowledge and the enduring power of ideas.

Tim Harford tar kål på låtsasvetenskap som sprids av politiker, media, företag och mindre nogräknade forskare. Programmet reder ut om siffror som slängs runt i debatten är sanna, eller relevanta.
