Two young listeners emailed the programme to ask how we calculate the distance to the sun. We decided to invite them and their parents to More or Less towers where Andrew Pontzen, an astrophysicist at University College London was on hand to explain the answer. A BBC nature documentary stated that there are 14,000 ants to every person on earth, and that were we to weigh all of these ants they would weigh the same as all the people. Can this be true? Tim Harford and Hannah Moore investigate with the help of Francis Ratnieks, professor of apiculture at the University of Sussex.
Start the Week - Karen Armstrong on War and Religion
Karen Armstrong argues against the notion that religion is the major cause of war. The former nun tells Tom Sutcliffe that faith is as likely to produce pacifists and peace-builders as medieval crusaders and modern-day jihadists. But Justin Marozzi charts the violent history of Baghdad and asks what role religion had to play there. The philosopher Christopher Coker explores how warfare dominates our history, and argues that war, like religion, is central to the human condition. Producer: Katy Hickman.
More or Less: Behind the Stats - The Barnett Formula
This week Tim explains the Barnett Formula with a bit of help from Money Box's Paul Lewis. He looks at Ed Balls sleight of hand in his speech to the Labour Party Conference. Is Ed Miliband's promise on NHS funding really worse than the funding increases delivered by Margaret Thatcher? And how do we know how far away is the sun really is?
Start the Week - Hilary Mantel
Hilary Mantel takes a break from her award-winning series of novels charting the rise and fall of the Tudor fixer, Thomas Cromwell, to discuss her new collection of short stories. She talks to Tom Sutcliffe about why her latest work eschews the historical to focus on contemporary Britain. The Director of the British Museum, Neil MacGregor tells the story of Germany from its Roman past to the present day through objects that symbolise the dynamic changes in its culture and identity. 'English Magic' is the focus of the artist Jeremy Deller's touring exhibition which melds myth, folklore and politics to explore British society. And the Jamaican poet Kei Miller pits the scientific cartographer against the spiritual map builder to explore our understanding of place and territory. Producer: Katy Hickman.
More or Less: Behind the Stats - WS MoreOrLess: The UK vs Mississippi
Is Britain poorer than every US state, except for Mississippi? Journalist Fraser Nelson calculates that?s the case. Tim Harford speaks to economist Chris Dillow about why he?s right. Late last year BBC Trending referred to Eritrea as ?tiny?. Listeners complained and the complaint was upheld. More or Less talks to Trending producer Mukul Devichand and asks whether any country can rightly be called ?tiny?.
More or Less: Behind the Stats - Kidney donation: the chance of finding a match
The chance of a successful kidney match between two unrelated people has increased significantly in the past ten years - why? Tim Harford speaks to Professor Anthony Warrens, president of the British Transplantation Society. Donations to the Manchester Dogs' Home have exceeded ?1m in the wake of a fire, which killed more than 50 dogs. The large sum raised caused Today presenter Justin Webb to comment that it often seems easier to raise money for animals than humans who are in need. Is it true that we give more generously to animals? Ben Carter reports. An edition of BBC Four's Wonder of Animals states that there are 14,000 ants to every person on earth, and that were we to weigh all of these ants they would weigh the same as all the people. Can this be true? And a complaint has been held up against a BBC programme for calling Eritrea 'tiny'. Can any country rightly be described this way?
More or Less: Behind the Stats - Shakespeare vs Rappers
It's a 'fact' beloved of English teachers around the world: that Shakespeare, the greatest playwright in English, also had the greatest vocabulary. But research published earlier this year suggests English teachers might have to look elsewhere to establish the superiority of the Bard - apparently his vocabulary lags behind the best and most famous rappers of the last decades. Is this comparison fair, and if so, does it diminish the Bard's lustre? This programme was first broadcast on the BBC World Service.
More or Less: Behind the Stats - Scottish referendum polls
Tim Harford talks to pollsters about how they are trying to gauge the political mood in Scotland, and he analyses Nigel Farage's claim that more than half of Scotland is on benefits. Plus: celebrating Countdown, the longest-running TV quiz show; quantifying malnutrition in the UK; and does the ?Curse of Strictly Come Dancing? really exist?
More or Less: Behind the Stats - WS MoreOrLess: To ice or not to ice?
The ALS ice bucket challenge has become a viral phenomenon. People around the world have been dousing themselves in ice-cold water and in the process have raised over $100m for charity. But a true nerd doesn't run with the herd, and Tim Harford is only going to do the challenge if the facts stack up. He investigates whether a viral challenge like this is good for charitable giving overall, and whether there are reasons to be more choosy about the charities we give to. This programme was first broadcast on the BBC World Service.
More or Less: Behind the Stats - To ice or not to ice?
The ALS ice bucket challenge viral phenomenon has raised over $100m. Is this good for charitable giving overall, and should we be more choosy about the charities we give to? Plus: is there a 'rising tide' of anti-Semitism in Europe; does Shakespeare have the largest vocabulary, or is the Bard bested by hip hop?s finest; and is the current generation of young people likely to live shorter lives than their parents?
