Membership is open to anyone interested in physics.
Sigma Pi Sigma was founded on December 11, 1921. The University of Evansville chapter of the Society of Physics Students was one of the 336 chapters established at the inception of SPS with a charter date of April 22, 1968. Our chapter was the 67th chapter of Sigma Pi Sigma to be established. Currently there are over 400 active chapters of Sigma Pi Sigma nationwide. The first person on our Sigma Pi Sigma membership list is James F. Sears who was the head of the physics department at that time.
