The International Union of Pure and Applied Physics declared the year 2005 as the World Year of Physics.
Why?
In 1905, Albert Einstein submitted five papers for publication in Annalen der Physik, covering three topics: the photoelectric effect, brownian motion, and the special theory of relativity. Although diverse in subject matter, these contributions are landmarks in their field - and testament to Einstein's genius. To honour their centenary, 2005 has been designated 'World Year of Physics'.
The World Year of Physics 2005 is a United Nations endorsed, international celebration of physics.
