Physicist Murray Gell-Mann died recently at the age of 89. He received the 1969 Nobel Prize in Physics for his work on the theory of elementary particles, and is credited with giving quarks their name. But he was known for more than just physics—he was a co-founder of the Santa Fe Institute, and a champion of creativity and interdisciplinary research.  

One of his biggest interests was exploring the “chain of relationships”  that connects basic physical laws and the subatomic world to the complex systems that we can see, hear, and experience. He joined Ira in 1994 to discuss those chains, the topic of his book “The Quark and the Jaguar.”
