Sigma Pi Sigma exists to honor
outstanding scholarship in physics; to encourage interest
in physics among students at all levels; to promote an
attitude of service of its members towards their fellow
students, colleagues, and the public; to provide a
fellowship of persons who have excelled in physics. Sigma
Pi Sigma’s mission is not completed in the induction
ceremony with the recognition of academic accomplishment.
In the four dimensions of Honor, Encouragement, Service,
and Fellowship, the mission of Sigma Pi Sigma takes a
longer view.
Founded in 1921, Sigma Pi Sigma is a member honor society
of the Association of College Honor Societies. Our society
has some 75,000 historical members. Election to Sigma Pi
Sigma is a lifetime membership.
The Society of Physics Students (SPS) was formed in 1968
with the union of Sigma Pi Sigma and the AIP Student
Sections. Today Sigma Pi Sigma is housed within the
SPS.
