The death was confirmed by Jenna Marshall, a spokeswoman for the Santa Fe Institute, which Dr. Gell-Mann helped found. Dr. Gell-Mann and other physicists also suggested that quarks must possess another property in addition to flavor. “I predicted that experimental physicists would find certain ones; that they would not find others,” Dr. Gell-Mann once said. According to Caltech, Dr. Gell-Mann eventually became interested in the idea of complexity, a concept that is common to disciplines including biology, ecology, sociology, and computer science. Summarizing his theoretical studies in 1969, when he won the Nobel, Dr. Gell-Mann said, “Our work is a delightful game.”
