iPod owners and laptop users will appreciate why. The 2007 Nobel prize in physics has recognised the discovery that allowed the miniaturisation of hard discs. Albert Fert of the University of Paris-South in France and Peter Grünberg of the Jülich Research Centre in Germany share the gong for independently discovering giant magneoresistance in 1988. When information stored magnetically on a disc is read, it has to be converted into an electric current. While most materials show slightly changed electrical conductivity when magnetised,
