Posted on behalf of Rob Robinson, President of the Australian Institute of Physics.
The 2014 Nobel Prizes have been announced, and both the physics and chemistry prizes fit neatly with the coming International Year of Light.
Blue light-emitting diodes (LEDs) have opened up a new era in energy-efficient lighting and computer and smartphone displays. They earned the Nobel Prize in Physics for Isamu Akasaki, Hiroshi Amano and Shuji Nakamura. As my Japanese colleagues have proudly indicated, this is also a win for applied physics, with much of the initial work having been done in industry.
