In the Bahamas, Chris dives into one of the biggest questions in nature - how intelligence itself evolved, and how it arose in the dolphin's mind. Inside each is the result of a three-billion-year journey.
In a series about scientists with brilliant minds, James Lovelock explains how his maverick way of thinking led him not only to technical breakthroughs in atmospheric detection systems on Earth and Mars, but also to Gaia - a new way of thinking about the Earth as a holistic, self-regulating system. He tells of his struggle against the scientific consensus of the day, the ridicule of his peers and his belief that the mainstream scientific establishment stifles intellectual creativity.

This time Mark explores the most visionary of all genres - science fiction, and shows how film-makers have risen to the challenge of making the unbelievable believable. Always at the forefront of cinema technology, science fiction films have used cutting-edge visual effects to transport us to other worlds or into the far future. But as Mark shows, it's not just about the effects. Films as diverse as 2001, the Back to the Future trilogy and Blade Runner have used product placement and commercial brand references to make their future worlds seem more credible. The recent hit Arrival proved that the art of film editing can play with our sense of past and future as well as any time machine. Meanwhile, films such as Silent Running and WALL-E have drawn on silent era acting techniques to help robot characters convey emotion. And District 9 reached back to Orson Welles by using news reporting techniques to render an alien visitation credible. Mark argues that for all their spectacle, science fiction films ultimately derive their power from being about us. They take us to other worlds and eras, and introduce us to alien and artificial beings, in order to help us better understand our own humanity.

Helen Czerski ventures beyond the visible spectrum in the final (and best) episode in this vibrant little series, showing how electromagnetic radiation is so much broader than the narrow slice of reality we see with our eyes. Before delving into the details of UV, infrared and x-rays, Dr Czerski explores colour subjectivity by trying on a dress that recently divided the internet — to some it appeared blue and black, to others white and gold. It's a perfect fit. It's also a neat analogy of how people can have opposing views but both swear blind that their perspective is correct. The series ends with some amazing imaging techniques that show our bodies in a whole new light.

Scientists are now finally discovering what thinkers, musicians, or even any of us with a Spotify account and a set of headphones could have told you on instinct: music lights up multiple corners of the brain, strengthening our neural networks, firing up memory and emotion, and showing us what it means to be human. In fact, music is as essential to being human as language and may even predate it. Can music also repair broken networks, restore memory, and strengthen the brain?

Celebrate the 50th anniversary of the concert that became a touchstone for a generation. This film brings the three-day concert to life through the voices of those who were present at what became the defining moment of the counterculture revolution. In August, 1969, half a million people from all walks of life and every corner of the country converged on a small dairy farm in upstate New York. They came to hear the concert of their lives, but most experienced something far more profound.

Film about the pop culture phenomenon that is Daft Punk, the duo with 12 million albums sold worldwide and seven Grammy awards. Throughout their career Thomas Bangalter and Guy-Manuel de Homem-Christo have always resisted compromise and the established codes of show business. They have remained determined to maintain control of every link in the chain of their creative process. In the era of globalisation and social networks, they rarely speak in public and neither do they show their faces on TV. This documentary explores this unprecedented cultural revolution, revealing two artists on a permanent quest for creativity, independence and freedom. Between fiction and reality, magic and secret, future and reinvention, theatricality and humility, The Robots have built a unique world. The film combines rare archive footage as well as exclusive interviews with their closest collaborators who talk about their work with Daft Punk, including Pharrell Williams, Giorgio Moroder, Nile Rodgers and Michel Gondry.

Ian Hislop and John Eliot Gardiner reveal the story behind Beethoven's Fifth Symphony. Described as the 'greatest 'great' piece ever written,' its opening notes are among the most recognisable in history. But no one really knows what Beethoven was trying to express with this piece. The traditional wisdom is that he is railing against fate and his deafness. But John Eliot believes the music expresses Beethoven's belief in the French Revolution. This is turbulent music from a turbulent man living in a turbulent age. John Eliot and Ian Hislop bring to life the exciting and dangerous times that shaped Beethoven personally and creatively.

How to have a happier life and a better world all thanks to maths, in this witty, mind-expanding guide to the science of success with Hannah Fry. Following in the footsteps of BBC Four's award-winning maths films The Joy of Stats and The Joy of Data, this latest gleefully nerdy adventure sees mathematician Dr Hannah Fry unlock the essential strategies you'll need to get what you want - to win - more of the time. From how to bag a bargain dinner to how best to stop the kids arguing on a long car journey, maths can give you a winning strategy. And the same rules apply to the world's biggest problems - whether it's avoiding nuclear annihilation or tackling climate change.

Hannah explores a paradox at the heart of modern maths, discovered by Bertrand Russell, which undermines the very foundations of logic that all of maths is built on. These flaws suggest that maths isn't a true part of the universe but might just be a human language - fallible and imprecise. However, Hannah argues that Einstein's theoretical equations, such as E=mc2 and his theory of general relativity, are so good at predicting the universe that they must be reflecting some basic structure in it. This idea is supported by Kurt Godel, who proved that there are parts of maths that we have to take on faith. Hannah then explores what maths can reveal about the fundamental building blocks of the universe - the subatomic, quantum world. The maths tells us that particles can exist in two states at once, and yet quantum physics is at the core of photosynthesis and therefore fundamental to most of life on earth - more evidence of discovering mathematical rules in nature. But if we accept that maths is part of the structure of the universe, there are two main problems: firstly, the two main theories that predict and describe the universe - quantum physics and general relativity - are actually incompatible; and secondly, most of the maths behind them suggests the likelihood of something even stranger - multiple universes. We may just have to accept that the world really is weirder than we thought, and Hannah concludes that while we have invented the language of maths, the structure behind it all is something we discover. And beyond that, it is the debate about the origins of maths that has had the most profound consequences: it has truly transformed the human experience, giving us powerful new number systems and an understanding that now underpins the modern world.
