Mathematical modelling with Lisa Jardine

On Start the Week Lisa Jardine discusses how complex maths has broken free of the laboratory and now influences every aspect of our lives. James Owen Weatherall applauds the take-over of the financial world by physicists, Marcus du Sautoy revels in the numbers and Kenneth Cukier explores how big data will change everything from disease control to bargain buys. But the cultural commentator Tiffany Jenkins sounds a note of caution about a world where everything is measurable.
