Photoemission 100 years after Einstein In 1921 Einstein won the Nobel Prize not for his work on relativity, but for solving a puzzle that had baffled scientists since 1887 - the photoelectric effect. In one of the three ground-breaking papers he published in 1905 he explained it in one astonishing blow: the light is quantized. His work was the first step in launching quantum theory.Tomorrow New Journal of Physics (NJP) publishes a special celebratory focus issue containing a series of new papers looking at the latest applications of the phenomenon first explained by Einstein one hundred years ago. NJP is co-owned by the Institute of Physics and Deutsche Physikalische Gesellschaft (the German Physical Society).
