Lighting the world

German physicist Peter Grunberg, co-winner of a Nobel, not only inspires Chinese researchers but also plays ping-pong with them, Liu Xiangrui reports.

German physicist Peter Grunberg, who won the Nobel Prize in 2007 along with fellow French-born scientist Albert Fert for their work in the field of magnetism, has always urged Chinese researchers to target "simple but important discoveries".

The Fert-Grunberg discovery revolutionized reading data on hard disks and even made disk sizes smaller.
