Theoretical physicist and best-selling author Brian Greene takes us on a journey through the discoveries of quantum physics. How is it that Newtonian mechanics gave way to the more complex and modern world of quantum mechanics?
As the theories on quantum mechanics begin to take shape, the 1927 Solvay Conference becomes a battleground for new scientific ideas. The world’s most brilliant minds, including Einstein and Bohr, try to crack the nature of the subatomic world. Join Brian Greene in exploring this fascinating period.

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.

Scientists investigate the way the Sun builds its power -- through fusion -- hoping to find a way to use fusion as a less dangerous and less radioactive waste-producing path to energy than fission. But there are some major difficulties along the way...

Engineer Jem Stansfield looks back through the Horizon archives to find out how scientists have come to understand and manipulate the materials that built the modern world. Whether it's uncovering new materials or finding fresh uses for those we've known about for centuries, each breakthrough offers a tantalising glimpse of the holy grail of materials science - a substance that's cheap to produce and has the potential to change our world. Jem explores how a series of extraordinary advances have done just that - from superconductors to the silicon revolution.
There is something very strange happens in space – something that should not be possible. It’s as if large parts of the world are being ravaged by a huge and invisible celestial vacuum. Sasha Kaslinsky, the scientist who discovered the phenomenon, is understandably nervous: “We left very upset and nervous,” he says, “because this is not something we planned to find.”
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.
In this extraordinary documentary we are going to witness very different kinds and situations of snowing: from howling blizzards to the gentlest and loveliest of weather events, from huge handkerchiefs quietly falling to the needle-sharp attack of hard, heavy grains. Snow - what is it really? How is it created - naturally and artificially? Thanks to CGI and new camera techniques we can actually see this process for the first time and listen to the incredible, inaudible music of snowfall, of myriads of tiny crystals touching and rolling and settling. Each snowflake is unique and bears more secrets than we could imagine. Did you know that different kinds of music influence the crystallization process and the shape of snowflakes? And have you ever imagined that we would be able to produce artificial snow that melts at 30 degrees Celsius? With this in mind: just let it snow!
