The Santa Fe Institute celebrates one of its founders with a new edition of a seminal work by the late Nobel laureate Murray Gell-Mann. Originally published in 1994, The Quark & the Jaguar spans the simple and the complex, examining the relationship between the fundamental laws of physics and the complexity and diversity of the natural world.Neither autobiography nor strictly scientific treatise, this uniquely personal and unifying vision reflects Gell-Mann's broad expertise, curiosity, and passion for topics as disparate as archaeology, linguistics, and computing.
