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.
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.

Hurtling across the galaxy in a starship powered by anti-matter isn't some sci fi writer's impossible dream, as Dr Michio Kaku proves when he reveals his blueprints for a spacecraft that can journey to the stars. Alpha Centaurii is nearer than you think.
Professor Iain Stewart reveals the story behind the Scottish physicist who was Einstein's hero; James Clerk Maxwell. Maxwell's discoveries not only inspired Einstein, but they helped shape our modern world - allowing the development of radio, TV, mobile phones and much more. Despite this, he is largely unknown in his native land of Scotland. On the 150th anniversary of Maxwell's great equations, scientist Iain Stewart sets out to change that, and to celebrate the life, work and legacy of the man dubbed 'Scotland's Forgotten Einstein'.

Deep underground in a vault beneath Paris lives the most important lump of metal in the world - Le Grand K. Created in the 19th century, it's the world's master kilogramme, the weight on which every other weight is based. But there is a problem with Le Grand K - it is losing weight. Professor Marcus du Sautoy explores the history of this strange object and the astonishing modern day race to replace it.
