1. -10-09-07 Nobel Prizes for Physics Announced (CBS News)
   "France's Albert Fert and German Peter Gruenberg won the 2007 Nobel Prize in physics on Tuesday for their discovery of giant magnetoresistance, a process used by billions [sic] of people on their computers and digital music players."
   
   "In 1988 Fert and Gruenberg each independently discovered a totally new physical effect, GMR. In this effect, very weak changes in magnetism generate larger changes in electrical resistance. This is how information stored magnetically on a hard disk can be converted to electrical signals that the computer reads." 10-07
