Does a full moon make crime rates go up?

Does a full moon make crime rates go up?

The Moon is one of the most captivating features of our night's sky, and apparently, one of the most suspicious.... For thousands of years, people have blamed the full moon for strange behavior. From ancient myths and the origins of the word lunacy to modern police folklore, the idea that a bright moon can influence human actions is one that many believe. But what does the data tell us? We spoke to Professor Eric Chudler, who has looked at crime rates and lunar cycles to discover whether the moon truly is the ultimate crime puppeteer.

Examining the numbers behind Andy Burnham’s ‘Manchester Miracle’

Tim Harford investigates some of the numbers in the news. This week: (00:23) Andy Burnham may not be Prime Minister yet, but he’s setting out his economic agenda, and its based on his old stomping ground, Greater Manchester. We ask whether the official figures that seem to show an economic miracle can be fully believed, and how much credit he deserves. (10:09) As our towns and cities get hotter, would turning to air conditioning really drive outside temperatures up by 10 to 12 degrees celcius? We learn about the fascinating world of ‘urban heat islands’. (15:40) We turn to homophones in an attempt to continue a running joke. This week, we follow six items about Wales with an item about whales - are our cetacean friends the carbon sinks of our dreams? Will we ever write a stranger paragraph? (22:10) Cult director and maths fanboy Werner Herzog has been waxing lyrical about the intruiging mysteries of prime numbers. Tim cracks out a surprisingly decent impression and we learn about one of the most inscrutable problems in mathematics - what’s not to like? More or Less is the programme that looks at numbers and statistics in news and in life. We’re always looking for questions from listeners - you can contact us on moreorless@bbc.co.uk.

The messy history behind the modern calendar

This year, the UK has had its hottest May and June days on record, with the mercury hitting the high thirties. But while the markings on a thermometer seem scientific and regular, the way we split up our calendar does not. Why, for instance, does May have 31 days and June have 30? To find out why our calendar has its modern form, we speak to Kristen Lippincott, former director of the Royal Observatory at Greenwich, and author of The Story of Time.

Benefits vs minimum wage: Which pays more?

Tim Harford investigates some of the numbers in the news. This week: (00:42) Former Chancellor of the Exchequer Sir Jeremy Hunt argues that you can earn far more on out of work benefits than you can on the minimum wage. We argue his figures are deceptive - and we’ve done the homework to prove it. (09:09) As the heatwave rises to a crescendo, people are saying that wet bulb temperatures could hit critical levels. Utterly mystified? So was our editor, so we made this item to explain all to him (and you). (14:34) In a tournament with so many teams, we’ve had to consult a university professor to understand the mysterious mathematical workings of the World Cup Draw. It’s even more complicated and confusing than VAR! (OK, it’s not that bad.) (19:00) Welsh comedian Elis James has a superpower - finding mutual connections with his fellow countrymen and women. So let’s add to the fun by providing a statistical framework upon which to understand his achievements. That’s how comedy works, right? More or Less is the programme that looks at numbers and statistics in the news and in life. We’re always looking for questions from listeners - you can contact us on moreorless@bbc.co.uk. Guests: Eduin Latimer - Senior Research Economist at the Institute for Fiscal Studies Dr Chloe Brimicombe - climate scientist and postdoctoral researcher at the University of Oxford Dr Kat Phillips - innovation research associate at the University of Warwick and a digital maths communicator under the name ‘KatDoesMaths’ Oliver Johnson - Professor of Information Theory, the University of Bristol Returning Special Guest appearance: Elis James: comedian and well-connected Welshman Presenter: Tim Harford Series Producer: Tom Colls Reporter: Nathan Gower Producers: Josh McMinn, Lizzy McNeill Editor: Richard Vadon Programme Coordinator: Brenda Brown Sound Engineer: James Beard

Is the US worse than North Korea for malnutrition deaths?

This surprising claim was spotted circulating on social media: ‘The United States has surpassed China and North Korea in deaths from malnutrition’. The claim used analysis from the Global Burden of Disease database for their sums. The data does indeed show that the US records more deaths from Malnutrition than China and North Korea. The rate in the US was 2.8 deaths per 100,000 compared to just 1.7 deaths per 100,000 for North Korea. From what we know about the two countries this seems unlikely, so what’s going on here? We talk to Dr Krstina Newport, Chief Medical officer for the American Academy of Hospice and Palliative Care Medicine to find out more.
