Devastating floods have wreaked havoc across Pakistan after the heaviest monsoon rains in at least a decade. But is a third of the country really under water, as has been claimed? Also why do electricity prices in the UK rise in line with gas prices when we get so much of our power from other sources like nuclear, wind and solar? As criminal barristers go on strike in England and Wales, we ask if those starting in the profession really earn ?12,200 a year. And as Boris Johnson waves goodbye to Downing Street, we investigate his claim that 70% of the UK now has access to gigabit broadband.

Daily advances in the technology of artificial intelligence may leave humans playing catch-up ? but in at least one area we can still retain an edge, mathematics. However it?ll require changes in how we think about and teach maths and we may still have to leave the simple adding up to the computers. Junaid Mubeen, author of Mathematical Intelligence, tells Tim Harford what it?ll take to stay ahead of the machines.

With energy prices in the UK spiralling, Tim Harford asks whether there is an easy and realistic way for bills to be cut. Also the number of excess deaths in the UK is rising ? we?ll hear how much covid is still to blame. We return to the subject of counting in twenties, this time hearing how the Welsh language mixes traditional and decimal systems. And we debunk some spurious social media claims around Liverpool players and asthma medication.

When the official figures were announced in Kenya?s presidential election, it looked like the total percentage share of the vote for each candidate came to more than 100%. As this should not be possible, many wondered if up to 142,000 votes might be miscounted. We explore what turns out to be a simple mathematical misunderstanding of the numbers.

Videos on TikTok have been claiming that so-called ?natural? birth control methods can be 99% effective. We examine what we really know, and how we know it.

The opinion polling industry?s reputation has taken a battering in recent years, as high profile slip-ups in the US presidential election exposed frailties. So should we write them off? Not according to Economist data journalist G Elliot Morris, who?s written a book called Strength in Numbers: How Polls Work and Why We Need Them.

Ahead of the opening of the new season of the English Premier League, baseless rumours and dodgy statistics circulating online have implied that Liverpool FC use asthma medication to enhance their players? performance.

Ben Carter speaks to sports scientist Professor John Dickinson to examine the science that disproves these rumour, and tracks down its original source with the help of Mike Wendling from the World Service's Trending programme.

Why do we measure the world around us in the way we do? There is a rich history to be explored - from measuring the depth of the Nile in Ancient Egypt to the central role the French played in developing the metric system and the ultra-precise measurement systems we use today. Presenter Tim Harford is joined by journalist and author James Vincent to discuss the political, social and technological factors that have influenced how we size up our world.

US athlete Devon Allen has made global headlines this week after being disqualified from the 110m hurdles final at the World Athletics Championship in Eugene, Oregon. He was judged to have left the starting blocks a thousandth of a second too early. On More or Less we crunch the numbers behind false starts in athletics, asking how quick is too quick when it comes to reacting to a starting gun and whether something else might have gone wrong with the measurement system.
