SFI shines in 'golden age' of social science

Crossing disciplines, collecting new data in unconventional ways, and establishing a common language have long been hallmarks of scientific culture at the Santa Fe Institute. Now these same practices are spurring a "golden age" in social science, to which SFI researchers have made outsized contributions over the past 12 years, according to a perspective piece published February 2 in PNAS.

Research brief: Where should you park your car? The 1/2 rule

In a Journal of Statistical Mechanics paper published in July 2020, Paul Krapivsky and SFI Professor Sidney Redner report an idealized model for the optimal strategy to park in the very best spot that’s closest to your destination. The paper was selected by Physics World as one of  "The 10 quirkiest physics stories of 2020."
