The fiftieth anniversary of the original FPUT paper was the subject of the March 2005 issue of the journal Chaos, and the topic of the 25th Annual International Conference of CNLS. The University of Southern Mississippi and the University of Florida supported the Ulam Quarterly, which was active from 1992 to 1996, and which was one of the first online mathematical journals. Florida's Department of Mathematics has sponsored, since 1998, the annual Ulam Colloquium Lecture, and in March 2009, the Ulam Centennial Conference.
