Since 1927, at the Solvay Conference in Austria, European physicists of the late 19th and early 20th centuries, realized that the interpretations of their experiments with light and electricity required a different theory to explain why light behaves both as a wave and particle. The implications were profound.
Since 1927, at the Solvay Conference in Austria, European physicists of the late 19th and early 20th centuries, came to understand that their experiments with light and electricity necessitated a new theory to account for why light exhibits both wave-like and particle properties. The consequences were far-reaching.
