2005: Year of physics

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'. Here, Nature news joins the celebrations.
