On Start the Week Tom Sutcliffe looks at how science has shaped our civilisation. Mark Miodownik explores how the discovery of new materials has transformed the way we live, from the Stone Age to the Silicon Age. While the mathematician Ian Stewart argues that calculations made centuries ago have led to untold innovations, and that mathematical equations really have changed our world. The natural world is the starting point for the sculptor, Peter Randall-Page and his abstract geometric form carved in stone. And Jane Rapley from Central Saint Martins College of Art and Design considers how far fashion designers are influenced by modern materials and techniques, and inspired by the natural world.
