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.

50 Things That Made the Modern Economy - Air Conditioning

Tim Harford tells the surprising story of air conditioning which was invented in 1902 to counter the effects of humidity on the printing process. Over the following decades “aircon” found its way into our homes, cars and offices. But air conditioning is much more than a mere convenience. It is a transformative technology; one that has had a profound influence on where and how we live.

CrowdScience - How Many People Can Earth Support?

Our planet is getting rather cosy. In just over 200 years, the global population has grown from 1 billion to almost 7.5 billion – and the best estimates suggest it’s going to keep on increasing. But just how far can it go? When will we reach ‘peak human’? That’s what CrowdScience listeners Alan Donaldson and Francoise Brindle want to know: what’s the latest estimate for how many people the Earth can support?

It’s a question that’s been bothering some of the world’s greatest thinkers for hundreds of years, and now presenter Marnie Chesterton goes on her own quest for answers. Her journey takes her through the technology and innovation that keeps our growing population alive, and she looks to Dhaka, Bangladesh, to find out what a more densely populated world might feel like. But are there signs that things are already levelling off? And could improving photosynthesis allow populations to grow without destroying the environment?
