The mission of the American Institute of Physics' (ADP) Center for History of Physics "is to preserve and make known the history of modern physics and allied fields." Visiting the History Exhibits, teachers and students can find interactive tutorials about many prominent physicists and important research such as Heisenberg's theory of uncertainty and the discovery of the electron. Users can search Emilio Segr"'s collection of 25,000 historical photographs, slides, lithographs, engravings, and other images. Researchers can find out how to gain access to the books, journals, photographs, interviews, and other historical documents held at the Niels Bohr Library. Educators can find helpful sample syllabi and reading lists created by physics instructors. With so much historical physics information to offer, anyone interested in physics would benefit by visiting this site.
