SUN 20:00 Sound Waves: The Symphony of Physics (b08h9ctd)
Series 1

Using Sound

Dr Helen Czerski examines the extraordinary messages sound waves carry and how they help us understand the world around us.

Visiting a hidden location buried beneath the hills of Scotland, Helen experiences some of the most extreme acoustics in the world. Here she learns just how much information can be carried by sound. She discovers how sound has driven the evolution of truly incredible biological systems and complex relationships between creatures that exploit sound for hunting - and escaping from predators. Helen demonstrates how sound waves diffract (bend around objects) and in doing so help us sense danger and locate it.

Through the story of a cochlea implant patient Helen explores the complicated way our ears can translate sound waves - a physical vibration in the air - into an electrical signal our brain can understand.

Helen explains how we are not limited to passively detecting sound waves, we can also use them to actively probe the world. From detecting submarines to uncovering the secrets of our planet, sound waves are instrumental in revealing things hidden from the world of light. On the cold North Sea, Helen investigates how marine archaeologists are using sound waves to uncover the remarkable human stories buried beneath the sea. Yet we are not limited to using sound waves here on Earth, as Helen explains how sound has been used to better understand distant, alien worlds in the outer solar system.


SUN 21:00 Dark Matter: A History of the Afrofuture (m000wfcj)
The arc of black history shares an uncanny resemblance to the plot points of classic sci-fi including ‘alien’ abduction, enslavement and rebellion. It’s this unlikely relationship that provides the inspiration for Afrofuturism, the broad cultural trend that encompasses works by Jean-Michel Basquiat to Grace Jones, Solange Knowles and Sun Ra. In this film, we meet, see and hear from artists across three continents who each, in their own way, explore the Afrofuture to look at the horrors of the black past and imagine alternative futures.

The mysterious yet influential Detroit techno duo, Drexciya, take the Atlantic Ocean, a site of death and destruction during the African slave trade and reclaim it as a place of creation and beauty. Through a series of releases from the late 1990s through the early 2000s, they envisage the unborn children of enslaved pregnant women, thrown overboard during the Middle Passage to the Americas, adapting to breathe under water and thrive in a Black Atlantis. The mythos is vividly brought to life by the Drexciyan collaborator and graphic artist Abdul Qadim Haqq as a thriving, technological undersea world.

Visual artist Ellen Gallagher similarly transforms the violence of the ocean into rebirth and renewal. Her film Osedax, made with Edgar Cleijne, is an imaginative retelling of how the skeletal remains of dead whales sustain new life in the curious form of the bone-devouring worm of the title. Whereas for artist Hew Locke, as well as the ocean itself, it’s the Atlantic’s coastal fringes that inspire his world of bricolage phantoms, plucked from the ghost stories of a Guyanese childhood.

The Afrofuture is perhaps most commonly imagined through the rubric of outer space, thanks in no small part to avant-garde jazz musician and poet Sun Ra. Born in the southern US in the early 20th century, Ra underwent an interplanetary conversion, claiming to have been teleported to Saturn. As with funk pioneer, George Clinton, who describes a similar close encounter with extraterrestrials, Ra’s identification with an alien presence can be read as more than simple escapism. It’s also a biting satire on the alienating experience of being black in America. For Ra, space is also an alternate destiny for black people, as the title of his 1973 Afrofuturist feature film Space is the Place insists.

Reaching beyond these fictional ‘Afronauts’ is the conceptual artist Tavares Strachan. His performance piece, Star City, Training in Six Parts, sees Strachan visit the famous Russian space centre to undergo the same rigorous – and often tortuous – training of the Cosmonauts. Strachan likens one of the exercises, which measures our capacity to withstand disorientation and gravitational stress, to his impoverished upbringing in The Bahamas.

The film concludes with an exploration of the idea of double consciousness. Coined in the early 20th century by WEB Du Bois, the influential African American sociologist, double-consciousness describes how black people in western societies see themselves twice over. Through their lived experience but also how they’re perceived within a dominant white culture.

Curator and writer Ekow Eshun traces uses of the idea through Ralph Ellison’s lauded mid-20th-century novel Invisible Man, and painter Kerry James Marshall’s image of the same title, right up to the Black Lives Matter movement. Predicated upon recordings of anti-black violence often captured through digital tech, Eshun argues these ‘expose’ a double consciousness at work, the world as experienced and seen through black eyes, laid bare for all to witness.

Other artists and commentators featured in the programme include Nuotama Frances Bodomo, Aria Dean, Ayesha Hameed, Kiluanji Kia Henda, Shabaka Hutchings, Elvira Dyangani Ose, Cauleen Smith and Greg Tate.


SUN 22:00 African Renaissance: When Art Meets Power (m000lwf2)
Series 1

Ethiopia

In Ethiopia, Afua Hirsch traces a proud 3,000-year history as significant as any civilisation in the west. A beacon for the black diaspora, Ethiopia’s story is one of defiant independence, of kings and communists, of a country that has survived catastrophe but bounced back, underpinned by a culture inspired by an ancient faith and devotion.

At the heart of recent Ethiopian history is the complex reign of Emperor Haile Selassie. One of the most influential world figures of the 20th century, he was the midwife to African liberation and the generator of a global culture in Rastafarianism. Yet ultimately, Haile Selassie was a tragic figure.

With renowned artist Eshetu Tiruneh, Afua explores the impact of the 1974 famine that led to the emperor’s downfall, and she talks to photographer Aida Muluneh about her return from exile to the dynamic new Ethiopia of the 21st century responding to the dark days of the past.


SUN 23:00 The Great Butterfly Adventure: Africa to Britain with the Painted Lady (b07yqfkq)
The migration of the painted lady has long fascinated scientists, artists and nature lovers alike. The longest butterfly migration on earth, it sees millions of these delicate creatures travel from the desert fringes of north Africa, across thousands of miles of land and sea, before settling in the UK. However, the migration has never truly been understood, the mysteries of the painted lady never unravelled - until now. This documentary reveals the secrets of this extraordinary phenomenon. Observed, investigated and analysed by presenter Martha Kearney and entomologist Dr James Logan, it employs groundbreaking techniques to unlock the secrets of the painted ladies.

At a time when more than a third of Britain's butterfly species are classed as under threat of extinction or have already vanished, it documents the largest butterfly migration into the UK. Over the course of the butterflies' five-month quest from the Atlas Mountains to Great Britain, Martha and her companion - leading butterfly expert Constanti Stefanescu - follow them along the route, observing and investigating this breathtaking natural phenomenon.

Meanwhile, back at the cutting-edge Rothamsted Research Centre in Harpenden, Dr Logan complements their adventures on the road, conducting experiments into butterfly biology and behaviour and, from our communications centre, he is able to follow the butterflies as they make their way from Morocco to Britain.

This is a visceral journey with real jeopardy, a real-life detective story. We break away from the central narrative to unravel the mysteries of the painted lady via experiments, including how they navigate and move between different altitudes, and we examine their flight patterns. As well as experiments there are also standalone packages on a variety of subjects, including the decline of the British butterfly and how some species are fighting back with the help of conservation groups. Butterfly Conversation's legions of butterfly spotters track the migration and those pioneers who make the journey from Morocco in a single flight.

By the end of the programme we discover how this tiny creature weighing less than a single gram is capable of completing an epic 4,500 mile journey from Africa to Great Britain. And even more remarkably, the offspring of these multi-generational butterflies that help to complete the journey their parents started. Could it be that despite having no life experience or learned knowledge of the migration they are innately drawn to the species' route?

An unforgettable adventure, and a groundbreaking project.
