Millikin University - Decatur, IL
Sigma Pi Sigma



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. Honor, encouragement, service, and fellowship are the four main principles of SPS.


Sigma Pi Sigma is the official honor society of the physics profession. Through election to Sigma Pi Sigma, distinctive achievement and high scholarship in physics is recognized and celebrated.

Millikin University already has a well established honors program for its general student body but Sigma Pi Sigma bestows a different kind of honor on it's members. If a student qualifies and is nominated by their peers then trust is instilled in that nominee to uphold the four values of ∑π∑: Honor, Encouragement, Service, and Fellowship


By honoring high achievement in physics and upholding high standards for election into Sigma Pi Sigma, the Society provides an incentive for all physics students to rise to excellence. The Society also encourages physics interest and science literacy in the general public.

At Millikin University, ∑π∑ members are expected to encourage all the physics majors to excel in their studies. This encouragement reaches farther than the University campus however when members connect to students of all grade levels since physics is everywhere.


With the recognition of accomplishment comes a responsibility to service. As persons who earned our Sigma Pi Sigma insignia pins by midnight oil, we appreciate the struggles of fellow students and colleagues who are facing similar challenges. When our experience and resources are placed at their service, then Sigma Pi Sigma touches more lives than may be counted by the number of its members. Because we respect the struggle for excellence, we support the generations of students that follow us.
At Millikin University service means using your resources and talents to help those that need it. ∑π∑ members are known for their tenacity and dedication in great part to their commitment to service.


Sigma Pi Sigma members cut across generational lines. The first members were inducted in 1921. New members are added every year. This represents many generations of experience and wisdom that can be brought to bear on matters of common interest to all members.
Sigma Pi Sigma members cut across professional lines. Besides physicists, many members of other professions also enrich our ranks, uniting a diverse group of people who have shared in the culture and traditions of physics, and have demonstrated that they could excel in it.
With this common thread of a shared background in physics running through so rich a diversity of generations and professions, and with the publications and meetings of the Society available for communication instruments, Sigma Pi Sigma nurtures a spirit of professional community among its members, and encourages them to offer their collective wisdom and perspectives in the service of society.
