When the HMS Victory sank in 1744, with it went an inventor named John Serson and a device he’d dreamed up. He called it the “whirling speculum”, but we now know the basic idea as a gyroscope. Serson thought it could help sailors to navigate when they couldn’t see the horizon. Nowadays gyroscopes are tiny and, as Tim Harford describes, they are used to guide everything from submarines to satellites, from rovers on Mars to the phone in your pocket. They are also integral to drones – a technology that some believe could transform how we do our shopping. But for that, they’ll need to work in all weathers.

Harley-Davidson spent more than a century branding its motorcycles as the bikes for rebels and macho cowboys. They’re made in America, for Americans. But Harley’s core customers are aging and before long will die out. Younger generations aren't stepping up to take their place. If it wants to keep selling motorcycles, Harley-Davidson is going to have to look outside the U.S. for new buyers, and become a little less American in the process. But that isn't sitting well with its customer base. PLUS: One listener tells us about the Honda Civic that brought her and her husband together.

Plastic food packaging often seems obviously wasteful. But when Jacques Brandenberger invented cellophane, consumers loved it. It helped supermarkets go self-service, and it was so popular Cole Porter put it in a song lyric. Nowadays, people worry that plastic doesn’t get recycled enough but there are two sides to this story. Plastic packaging can protect food from being damaged in transit, and help it stay fresh for longer. Should we care more about plastic waste or food waste? As Tim Harford explains, it isn’t obvious and the issue is complicated enough that our choices at the checkout may accidentally do more harm than good.
