American Physical Society
The APS is now active in public and governmental affairs, and in the international physics community. It has programs in education, science outreach (specifically Physics Outreach), and media relations. APS has about 50,000 members. In 1999, APS Physics celebrated 100 years with the biggest-ever physics meeting in Atlanta. In 2005, APS took the lead role in United States participation in the World Year of Physics. It started several programs to publicize physics during the 100th anniversary of Albert Einstein's annus mirabilis. Einstein@Home, is still an ongoing and popular distributed computing project.
