50 Things That Made the Modern Economy - Tally Stick

Tally sticks were made from willow harvested along the banks of the Thames in London. The stick would contain a record of the debt. It might say, for example, “9£ 4s 4p from Fulk Basset for the farm of Wycombe”. Fulk Basset, by the way, might sound like a character from Star Wars but was in fact a Bishop of London in the 13th century. He owed his debt to King Henry III. Now comes the elegant part. The stick would be split in half, down its length from one end to the other. The debtor would retain half, called the “foil”. The creditor would retain the other half, called the “stock”. (Even today British bankers use the word “stocks” to refer to debts of the British government.) Because willow has a natural and distinctive grain, the two halves would match only each other. As Tim Harford explains, the tally stick system enabled something radical to occur. If you had a tally stock showing that Bishop Basset owed you five pounds, then unless you worried that Bishop Basset wasn’t good for the money, the tally stock itself was worth close to five pounds in its own right - like money; a kind of debt, which can be traded freely.

CrowdScience - Why do Human Faces Look so Different?

You don’t have to be a “super-recogniser” to know that human facial features are extremely varied. Just look around you. Yet look at a most other animals and you’d find it hard to tell individuals apart. So why are human faces so diverse?

We’ll also be finding out why salt tastes salty (warning: lots of spitting and gargling ahead) and one listener wants to know what would happen if one of the key ocean current systems, the North Atlantic Conveyer, slowed down or stopped altogether. Presenter Marnie Chesterton heads to the beaches on the West Coast of Scotland in search of answer. Do you have a question we can turn into a programme?

50 Things That Made the Modern Economy - Passports

How much might global economic output rise if anyone could work anywhere? Some economists have calculated it would double. By the turn of the 20th century only a handful of countries were still insisting on passports to enter or leave. Today, migrant controls are back in fashion. It can seem like a natural fact of life that the name of the country on our passport determines where you can travel and work – legally, at least. But it’s a relatively recent historical development – and, from a certain angle, an odd one. Many countries take pride in banning employers from discriminating against characteristics we can’t change: whether we’re male or female, young or old, gay or straight, black or white. It’s not entirely true that we can’t change our passport: if you’ve got $250,000, for example, you can buy one from St Kitts and Nevis. But mostly our passport depends on the identity of our parents and location of our birth. And nobody chooses those.

CrowdScience - Why is Childbirth Painful?

Childbirth is different for everyone. Depending on who you ask, it’s one of life’s greatest and worst experiences - and can be anything from traumatic and excruciating to life-affirming and spiritual. But what pretty much every mother will agree on is that it hurts. But why is such a fundamental aspect of life so painful? And why do some women find it worse than others?

Presenter Gareth Barlow – who doesn’t expect to be giving birth ever – goes on a quest to understand the experience of female labour pain and why evolution hasn’t given women an easier ride. He discovers the latest research into the nature and experience of pain and whether the idea of male/female pain thresholds, is a real thing. We also hear from CrowdScience listeners about their own experiences, and find out if having a supportive birth partner can help bringing new life into the world that little bit easier.

50 Things That Made the Modern Economy - Intellectual Property

When the great novelist Charles Dickens arrived in America in 1842, he was hoping to put an end to pirated copies of his work in the US. They circulated there with impunity because the United States granted no copyright protection to non-citizens. Patents and copyright grant a monopoly, and monopolies are bad news. Dickens’s British publishers will have charged as much as they could get away with for copies of Bleak House; cash-strapped literature lovers simply had to go without. But these potential fat profits encourage new ideas. It took Dickens a long time to write Bleak House. If other British publishers could have ripped it off like the Americans, perhaps he wouldn’t have bothered. As Tim Harford explains, intellectual property reflects an economic trade-off – a balancing act. If it’s too generous to the creators then good ideas will take too long to copy, adapt and spread. But if it’s too stingy then maybe we won’t see the good ideas at all. Producer: Ben Crighton Editors: Richard Knight and Richard Vadon (Image: Copyright stamp, Credit: Arcady/Shutterstock)

CrowdScience - Where’s my Ejector Seat?

Even if you spent your entire life on a plane, the chances are you’d never crash – commercial air travel is remarkably safe. But after hearing about a recent air tragedy, two brothers in Kampala wondered if commercial airplanes could ever have ejector seats – like fighter jets do - to give passengers a last option for escape.

We meet 98-year-old John Oliver “Jo” Lancaster, one of the first people ever to eject out of a plane, and discover the seemingly insurmountable barriers to fitting ejector seats into passenger jets. And we find out that an awful lot of work goes into making flying as safe as it is, as we visit an air accident investigation lab, practise an emergency exit from a passenger cabin and deal with a multiple engine failure …in a plane simulator.

But are any safety ideas as radical as ejector seats on the horizon? We assess a controversial design that would parachute the entire passenger cabin down to earth should the worst happen.

World Book Club - Derek Walcott – Omeros

This month we mark the recent death of the St Lucian poet, playwright and Nobel Laureate Derek Walcott with another chance to hear him talk-on-the-programme about his poetic masterpiece, the book-length Omeros.

Following the wanderings of an extraordinary cast of characters from the island of St Lucia, Omeros echoes Homer’s ancient-Greek epic of war and love and deadly rivalry, the Iliad, in order to dramatise the lives, sufferings, displacements and conflicts of the inhabitants of today’s Caribbean.

It also explores the islands’ violent history of colonial wars and slavery.

50 Things That Made the Modern Economy - Video Games

From Spacewar to Pokemon Go, video games – aside from becoming a large industry in their own right – have influenced the modern economy in some surprising ways. Here’s one. In 2016, four economists presented research into a puzzling fact about the US labour market. The economy was growing, unemployment rates were low, and yet a surprisingly large number of able-bodied young men were either working part-time or not working at all. More puzzling still, while most studies of unemployment find that it makes people thoroughly miserable, the happiness of these young men was rising. The researchers concluded that the explanation was simply that this cohort of young men were living at home, sponging off their parents and playing videogames. They were deciding, in the other words, not to join the modern economy in some low-paid job, because being a starship captain at home is far more appealing.

CrowdScience - Why Do We Have Males and Females?

Sex is responsible for the large variety of life on earth. Without the two sexes there is no sexual reproduction which means no shuffling of the genetic make-up – and no survival in a changing environment. But why do we have two sexes in the first place and does nature determine your sex? It’s with these questions and more that listener Du from Singapore persuaded the CrowdScience team to investigate the weird and wonderful world of sex. You might think that Nature would have standardised something as important as ensuring the continuation of the species. Far from it – species do sex in many different ways – some stranger than others.

Presenter Marnie Chesterton unpicks the zoological oddities of sex and along the way learns about her own sex chromosomes. We also meet an unlikely bird keeper, who is the proud owner of a female duck that is morphing into a male. Will her boyfriend, a male mandarin duck, mind the change?

50 Things That Made the Modern Economy - Cuneiform

The Egyptians thought literacy was divine; a benefaction which came from the baboon-faced god Thoth. In fact the earliest known script – “cuneiform” – came from Uruk, a Mesopotamian settlement on the banks of the Euphrates in what is now Iraq. What did it say? As Tim Harford describes, cuneiform wasn’t being used for poetry, or to send messages to far-off lands. It was used to create the world’s first accounts. And the world’s first written contracts, too.
