Material Chemistry:The Advanced Material World
Like it or not， ours is a material world. It's a potent symbol of that fascination with technology that makes us human. Eleven layers of synthetic fibre protect an astronaut in space. Teeth are reshaped with plastic， hardened by light. Artificial hips restore the ability to walk without pain. New metals and new versions of old metals， compete with ceramics tough enough to stop bullets and lightweight fibres stronger than steel. Plastic， carbon， metal and ceramic allow aircraft to fly faster， farther and higher.
