In 50 years from now, cities will be home to 70% of all human beings. They will have seven billion mouths to feed and will face an immense challenge in terms of food supply. Are hydroponics and vertical farming going to solve this challenge?
From the Stone Age to the Silicon Age, materials have helped drive forward our civilisation. By manipulating materials we have been able to transform our world and our lives - and never more so than in the past century when we have discovered and designed more materials than at any other time in human history. (Part 1: Metal) Professor Mark Miodownik travels to Israel to trace the history of our love affair with gleaming, lustrous metal. He learns how we first extracted glinting copper from dull rock and used it to shape our world and reveals how our eternal quest for lighter, stronger metals led us to forge hard, sharp steel from malleable iron and to create complex alloys in order to conquer the skies. He investigates metals at the atomic level to reveal mysterious properties such as why they get stronger when they are hit, and he discovers how metal crystals can be grown to survive inside one of our most extreme environments - the jet engine.
