Bridget Kendall and guests discuss the key components of the global story of the factory, tracing its development from eighteenth century Britain to twenty-first century China and beyond. Exploring how the factory came to shape not just the material world but entire social worlds too, they share their expert knowledge on topics such as the lives of factory workers, the capitalist and communist factory, and the changing face of manufacturing in an age of robots and smart technology.Bridget is joined by Joshua B. Freeman, Martin Krzywdzinski, Alessandra Mezzadri and Nina Rappaport. The sociologist Ching Kwan Lee also shares her insights into factory life in Shenzhen as it transformed in the late twentieth century.Image: Illustration of an old 18th century factory.

The ancient Inca town Machu Picchu is now the most visited tourist attraction in Peru - and yet it lay nearly forgotten for over three centuries until American and Peruvian explorers drew the world's attention to it in the 1910s. And despite a century of excavations at the site, there are still many unanswered questions about Machu Picchu: why was it built in the first place, who were the immigrants that made up a large proportion of the town's population and why was it abandoned so quickly.To find out more about Machu Picchu, Bridget Kendall is joined by leading archaeologists of the Inca civilisation Lucy Salazar and Michael Malpass, the celebrated mountaineer and explorer Johan Reinhard and by writer Mark Adams who retraced the steps of the 1911 expedition led by Hiram Bingham that put Machu Picchu back on the map.(Photo: Machu Picchu, Peru.

The birth of modern plastic began in 1907 with the invention of Bakelite, one of the first plastics to be made from entirely synthetic components. But plastic in a particular form was being used many thousands of years ago by the Olmec, the earliest known civilisation in Mexico, who played with balls made of a natural polymer - rubber. Over the years the plastics industry has grown from the work of a handful of inventors to a global player whose products reach into almost every corner of our lives. Plastic has been at the heart of one of the most important changes in virtually all societies since the second world war: the consumer revolution. But while it is a force for good in many areas and a highly versatile material that appears in the most surprising places, plastic today is a major environmental preoccupation. Can we modify our use towards this wonder material, or can scientists rise to the challenge of creating a plastic that will break down completely when it has reached the end of its useful life?Rajan Datar is joined by nanoscientist Professor Ajay Mishra, chemist Professor Andrea Sella and journalist Susan Freinkel to explore the story of plastic.Photo: Plastic bottles on a production line (Getty Images)

Rarely has one foodstuff had such global influence as Sugar – on our trade and economy, movement of people around the world, and health and treatment of fellow humans. Once a costly luxury called “white gold”, it was pivotal in one of mankind’s most shameful chapters – slavery. Joining Rajan Datar to find out more about Sugar and its connection with power is the Canadian historian Dr Elizabeth Abbott, the writer Marina Budhos whose Indian background inspired her research, and the Columbian political scientist Dr Eduardo Gomez, author of ‘Geopolitics in Health’.Photo: A sugar bowl (Getty Images)

It is a religion that has lasted three millennia, claims to be the world's first monotheistic creed and to have influenced major faiths such as Christianity, Judaism and Islam, inspired artists from Voltaire to Freddie Mercury but Zoroastrianism may be heading for extinction: in some communities only children of male Zoroastrians are admitted to the faith and there are probably fewer than 200 thousand left now. Rajan Datar talks about the history of Zoroastrianism with Dr. Sarah Stewart, Shapoorji Pallonji Lecturer in Zoroastrianism at SOAS, University of London, Malcolm Deboo, President of the Zoroastrian Trust Funds of Europe, the oldest Zoroastrian organisation on the continent, and Yuhan Vevaina, professor of Sasanian Studies at Oxford University.Photo: Faravahar - relief of winged sun symbol of Zoroastrianism in Persepolis city, Iran.

It was exactly a hundred years ago that women in the UK won the right to vote: though at first it was only for property owning women over thirty. But Britain wasn’t the trail blazer. Seven countries were ahead of it including two of its colonies. So what were the deciding factors? Was it the changing circumstances created by wars and the collapse of Empires? Or was it the suffragettes’ sometimes violent tactics? And why did Switzerland take as long as 1971 to enfranchise women? Joining Bridget Kendall to look at the global story of how women got the vote is the Indian social scientist Nikita Sud, Jad Adams the author of “Women and the Vote”, and Lindie Naughton the biographer of the first woman elected to the British parliament Constance Markievicz.Photo: Women voting (Reuters)

Today, we can’t imagine an election without an opinion poll gauging public opinion on who’s leading, who’s won a debate or who’s more popular with a specific group of voters. Even our favourite chocolate bars and footballers are subject to a poll. But how did straw polls evolve into the scientific number crunching we know now? What is their purpose and impact? How differently are they used around the world? And just how reliable are they?Bridget Kendall is joined by economist and chairman of Gallup Pakistan Dr Ijaz Shafi Gilani; Scott Keeter, senior survey advisor for the Pew Research Center in Washington; and Sir John Curtice from the University of Strathclyde.Picture: American President Harry S Truman smiles and waves to the excited Kansas City crowd after hearing the news that he had won the United States elections in 1948 and retained the Presidency, despite of what many polls had predicted, Credit: Keystone, Getty Images.

T.E Lawrence was a British scholar and adventurer whose involvement with the Arab Revolt during the World War One inspired one of the most celebrated films in cinema history. So how did a man who was offered a knighthood and became an international celebrity end his days in near obscurity? Bridget Kendall is joined by historians James Barr and Juliette Desplat, and writer Scott Anderson to discuss his life and legacy.Photo: T. E. Lawrence. Photo by Hulton Archive / Getty Images.

In the ten years since his death, the impact of designer Yves Saint Laurent on women’s fashion remains undimmed. The pea coat, the trench, the trouser suit – many of his designs are now staples of the modern Western woman’s wardrobe. So how did this famously shy and retiring man achieve global success? And did his fashion innovations for women shape social change in the 1960s, or were they a response to his times? Bridget Kendall looks back at Saint Laurent’s life and legacy with director of the Yves Saint Laurent Museum, Olivier Flaviano, fashion historian Emilie Hammen and one of Saint Laurent’s last assistants, designer Charles Sébline.Photo: Yves Saint Laurent, French designer, with two fashion models, Betty Catroux (left) and Loulou de la Falaise, outside his 'Rive Gauche' shop.

Moby Dick is the story of a crazed and vengeful sailor, Captain Ahab, hunting a giant whale that bit off his leg. It's a large and challenging book and its author, Herman Melville died without knowing how influential or revered it would become. Although it failed to impress when it first came out in 1851, it’s now hailed as a ‘great American novel’, one of the towering achievements of American literature. With Bridget Kendall to explore the book and its author, Professor Jamie Jones from the University of Illinois, Emily Ogden from the University of Virginia and poet and academic from Lancaster University in the UK, Paul Farley.
