In the first episode, Helen seeks out the colours that turned planet Earth multicoloured. To investigate the essence of sunlight Helen travels to California to visit the largest solar telescope in the world. She discovers how the most vivid blue is formed from sulfur atoms deep within the Earth's crust and why the presence of red ochre is a key sign of life. In gold, she discovers why this most precious of metals shouldn't even exist on the surface of the planet and in white, Helen travels to one of the hottest places on Earth to explore the role salt and water played in shaping planet Earth.

Early Earth was a canvas for the vast new palette of the colours of life, with the diversity of human skin tones telling the story of how humanity spread and ultimately conquered the planet. Dr Helen Czerski explores the true masters of colour - which are often the smallest and most elusive - travelling to the mountains of Tennessee to witness the colourful mating display of fireflies, and revealing the marine creatures that can change the colour of their skin in order to hide from the world.

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.

What does quantum mechanics tell us about our world -- or are there many worlds due to probability waves? How does the general theory of relativity mesh with quantum mechanics? If you've wished you understood quantum mechanics (or at least grasped the basics) physicist Brian Greene can help!

It appears we live in a universe filled with light. But scientists are now certain there is far more matter in the dark portions of our universe.

Ice is one of the strangest, most beguiling and mesmerising substances in the world. Full of contradictions, it is transparent, yet it can glow with colour, it is powerful enough to shatter rock, but it can melt in the blink of an eye. It takes many shapes, from the fleeting beauty of a snowflake to the multimillion-tonne vastness of a glacier and the eeriness of the ice fountains of far-flung moons. Science writer Dr Gabrielle Walker has been obsessed with ice ever since she first set foot on Arctic sea ice. In this programme, she searches out some of the secrets hidden deep within the ice crystal to try to discover how something so ephemeral has the power to sculpt landscapes, to preserve our past and inform our future.

Artist and writer Matt Collings takes the plunge into an alien world of equations. He asks top scientists to help him understand five of the most famous equations in science, talks to Stephen Hawking about his equation for black holes and comes face to face with a particle of anti-matter. Along the way he discovers why Newton was right about those falling apples and how to make sense of E=mc2. As he gets to grips with these equations he wonders whether the concept of artistic beauty has any relevance to the world of physics.

The idea that there is a possibility of many worlds or multi universal theory is very new even though you may have learned about it in movies and comic books. Explore how this thinking was developed in the world of quantum mechanics and philosophy.
