Peter Grünberg - the Joint Winner of this Year's Nobel Prize for Physics - Tomorrow Today, 09.12.2007

For three decades Peter Grünberg has worked at the Jülich Research Centre in western Germany. In the 1980s, he and his colleague Albert Fert from the University of Paris discovered giant magnetoresistance (GMR). The GMR effect led to the breakthrough in gigabyte hard disks used in virtually all computers today. It's for this achievement that Grünberg and Fert were honoured with the 2007 Nobel Prize for Physics. We visit Peter Grünberg and ask him what effect winning a Nobel has had on his life and his work.
