Serge Haroche won the Nobel Prize in Physics in 2012 along with American physicist David Wineland for their work on studying quantum phenomena when matter and light interact. The study of matter at its most fundamental level may be hard for many people to wrap their heads around, but as Haroche tells FRANCE 24, study in this field has led to the inventions of life-changing devices. "The GPS is based on atomic clocks; magnetic resonance imaging, which is used in medicine, is also based on quantum phenomena."
