L. Worth Seagondollar, former president of the Sigma Pi Sigma national physics honor society, passed away on September 20th. Worth was president at a central time for the society and was instrumental in affecting the merger of the AIP Student Sections and Sigma Pi Sigma that created the Society of Physics Students (SPS). Worth advised a very active local chapter of SPS at the North Carolina State University, where he also served as department head. As a member of the Manhattan Project, Worth was first to measure the critical mass of plutonium and was present at the Trinity Test. He was also a fellow of the American Physical Society.
In 2004, Worth recounted his experience working on and witnessing the explosion of the first atomic bomb to a packed house at the Sigma Pi Sigma Physics Congress. SPS invited him to present an encore to the ACP community in July 2007. A brief video clip of his talk can be seen on YouTube, and the entire transcript is available through the SPS website.
Sigma Pi Sigma's highest award is named after Worth and given to those who have shown an exemplary level of commitment and service to the SPS and ΣΠΣ.
