On Start the Week Andrew Marr discusses creativity with the writer Jonah Lehrer. In his latest book, Imagine, Lehrer unpicks the creative process in both science and art, to ask where inventiveness and imagination spring from, and how they can be harnessed. Experimental sound artist, Scanner, talks about creating unique musical compositions and his latest collaboration with the Heritage Orchestra at the Brighton Festival; and the novelist Joanna Kavenna considers the importance of nourishing creative ideas in writing fiction. She argues that everyone is born creative, although as we get older this innate imaginative ability is often suppressed or side-lined. Finally, the chemist, Rachel O'Reilly, explains the importance of the creative process in scientific research and how blue-sky thinking aids developments in nano-materials and technology.

Andrew Marr discusses the state of China with the authors Jonathan Fenby and Martin Jacques. Fenby attempts to draw together the whole of the China story to explore its global significance, but also its inner complexity and complexes. Martin Jacques has updated his bestseller, When China Rules the World, to argue that the country's impact will be as much political and cultural, as economic. But while China's finances make all the headlines, what of its literature? Ou Ning edits China's version of Granta magazine, showcasing the work of contemporary Chinese authors, but must tread a careful path to keep the right side of the censors. And the academic and translator Julia Lovell argues that to understand the new spirit of China, it's vital to read its often contrarian short fiction. Producer: Katy Hickman.
