The World Year of Physics: Einstein in the 21st Century


April 29, 2005 -- 2005 is the World Year of Physics, a U.N.-endorsed international celebration of physics. It also marks the 100th anniversary of the publication of Albert Einstein's series of papers that shook the foundations of modern science. At a National Academy of Sciences symposium, five speakers will discuss these papers and how Einstein's ideas still resonate in the most advanced areas of research in modern physics.

In one of his papers, Einstein showed that the fluctuating motions of Brownian particles in a fluid can be used to compute Avogadro's number, and thus to prove that atoms exist. In another, he showed that the photoelectric effect can be understood by assuming that light consists of quantized photons. And in another, he introduced his theory of special relativity, which forever changed our concepts of space and time. This public symposium will be held on Tuesday, May 3, from 2 p.m. to 5. p.m. in the auditorium of the National Academies building, 2100 C St., N.W., Washington, D.C.
