Paul Ehrlich: The man who bet England wouldn’t exist by the year 2000

Paul Ehrlich’s bestselling book The Population Bomb opens with an apocalyptic paragraph. “The battle to feed all of humanity is over,” it states. “In the 1970s and 1980s hundreds of millions of people will starve to death in spite of any crash programs embarked upon now. At this late date nothing can prevent a substantial increase in the world death rate.” Professor Ehrlich, who died last week, made a simple argument. The global population was outrunning our capacity to produce enough food to feed everyone. Famine, disease and nuclear Armageddon would follow if the population was not controlled. The book made him a celebrity, and he regularly spoke in public, warning of the imminent threat to humanity. Sometimes his warnings were quite vague in terms of the timescale, but other times not - he was reported as saying in 1968 that if current trends continued, by the year 2000, the UK would be a “small group of impoverished islands, inhabited by some 70 million hungry people". "If I were a gambler," he was quoted as saying, "I would take even money that England will not exist in the year 2000". But the UK did not collapse, the global death rate did not increase, and we have more food per person now than when he wrote the book. So, what went wrong with Paul Ehrlich's predictions of a population apocalypse?

Transgender women in sport: Does ‘comparable’ mean ‘equal’?

In most sports, men compete against men and women compete against women. That is generally considered fair, because men are faster, more powerful and have greater endurance. But there is an ongoing controversy about transgender women - people who were born male and now identify as women. Is it fair for them to compete in the women’s sport category or do they have an advantage? A study in the British Journal of Sports Medicine recently added to the debate with an analysis that found the strength and fitness of transgender women is “comparable” with that of women. More or Less looks into the research to explain what it does, and does not, say.

US-Israel war with Iran: Do the gulf states have enough interceptor missiles?

On Saturday 28th February, the US and Israel launched a military attack on Iran, targeting the country's missile infrastructure, military sites and leadership. In response, Iran launched a wave of strikes across the region, including on Israel and the Gulf states. Iran has a stockpile of ballistic missiles, which it’s firing at neighbouring countries. These countries in turn are using interceptor missiles to try and shoot them down. But is it clear who will run out of missiles first?

Has a company really discovered a million new species?

Have a million new species just been discovered? That’s the claim made by Dr Oliver Vince, co-founder of a company called Basecamp Research, who are collecting genetic data to train AI systems. The hope is that they’ll be able to use this to discover new medicines. But is this number a good one? Rob Finn, from the European Bioinformatics Institute, explains what is being counted and how you go about counting them.

Did AI researchers let AI hallucinations into scientific papers?

AI can make mistakes – and AI chatbots like ChatGPT warn you about that whenever you ask them anything. These mistakes sometimes involve making up entirely fictitious, factually false statements known as “hallucinations”. Whether these hallucinations matter depends on what you’re using AI for, and whether they are spotted and corrected. The team on More or Less were slightly surprised to read a headline in Fortune magazine, claiming that a top academic AI conference accepted research papers which contained 100 AI-hallucinated citations. You might think that the top AI researchers in the world would be careful about using AI to write their research papers. Alex Cui, CTO and co-founder of GPTZero – whose company discovered the hallucinations – explains what’s going on.

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.

NACHRICHTEN DES TAGES
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.

GESCHICHTE
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.

GESCHICHTE
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.

I love this show so much I hold listen to it everyday. Not only for its insights initially numbers but also into the broader societal impacts it offers.
No certainty in Numbers

A great show challenging my all too easy believe in numbers without dismissing the importance of statistics. And, the presentation is not as dry as the subjects the presenters are talking about.
Funny, brilliant

A beacon of crystal-clear accuracy in a world filled with fake news and numerical illiteracy. Harford is just excellent.

Is there any truth in Stats?? This show will help you in your critical thinking about them and if you have a question about any statistics you may have heard, ASK THEM!
