Murray Gell-Mann passes away at 89

Though he was best known for his contributions to particle physics, for which he won the 1969 Nobel prize in physics, Gell-Mann wanted to understand the “chain of relationships” that connected the universal laws of physics to complex systems like economies and human cultures. These two extremes of interest he described in his 1994 book, The Quark and the Jaguar, as “two aspects of nature…on the one hand, the underlying physical laws of matter and the universe, and on the other, the rich fabric of the world that we perceive directly and of which we are a part.”
