Over 80 years after her death, Maria Skłodowska-Curie remains by far the best-known female scientist. In her lifetime, she became that rare thing - a celebrity scientist, attracting the attention of the news cameras and tabloid gossip. This multi-layered film reveals the real Maria Skłodowska-Curie, an extraordinary woman who fell in love three times, had to survive the pain of loss, and the public humiliation of a doomed love affair. It is a riveting portrait of a tenacious mother and scientist, who opened the door on a whole new realm of physics, which she discovered and named - radioactivity.

Documentary-maker David Malone delves into the secrets of ocean waves. In an elegant and original film, he finds that waves are not made of water, that some waves travel sideways and that the sound of the ocean comes not from water but from bubbles. Waves are not only beautiful but also profoundly important, and there is a surprising connection between the life cycle of waves and the life of human beings.

David Malone asks if we are right to see the heart as merely a brilliant pump or whether it should be allowed to reclaim something of its old place at the centre of our humanity. The heart is the most symbolic organ of the human body.

Metamorphosis seems like the ultimate evolutionary magic trick - the amazing transformation of one creature into a totally different being: one life, two bodies.

The documentary looks at the modern advances in mathematics and how they affect our understanding of physics, economics, environmental issues and human psychology, as well as how developments in 20th Century mathematics have affected our view of the world, and particularly how the financial economy and earth’s environment are now seen as inherently unpredictable. The film examines the influence the work of Henri Poincare and Alexander Lyapunov had on later developments in mathematics. It includes interviews with David Ruelle, about chaos theory and turbulence, the economist Paul Ormerod about the unpredictability of economic systems, and James Lovelock the founder of Gaia theory about climate change and tipping points in the environment. As we approach tipping points in both the economy and the climate, the film examines the mathematics we have been reluctant to face up to and asks if, even now, we would rather bury our heads in the sand rather than face harsh truths.

Thought provoking Channel 4 series in which Sir Martin Rees investigates the great unanswered questions of science.
