Blue Nobel Prize – video

Three Japan-born scientists Isamu Akasaki, Hiroshi Amano and Shuji Nakamura won the Nobel Prize in physics Tuesday for the invention of blue light-emitting diodes, a new energy-efficient and environmentally friendly light source.

“The blue LED is a fundamental invention that is rapidly changing the way we bring light to every corner of the home, the street and the workplace — a practical invention that comes from a fundamental understanding of physics in the solid state,” said H. Frederick Dylla, the executive director and CEO of the American Institute of Physics.”
