Medieval friar William of Ockham posited a famous idea: always pick the simplest explanation. Often referred to as the parsimony principle, “Ockham’s razor” has shaped scientific decisions for ...

Applications for the third Complexity Global School (CGS) are now open. The school will be hosted at Universidad de los Andes in Bogotá, Colombia, and applicants from all countries are eligible to ...

This paper formally defines tipping points as a discontinuity between current and future states of a system and introduces candidate measures of when a system tips based on changes in the probability ...

Complex Systems Summer School (CSSS) offers an intensive four-week introduction to complex behavior in mathematical, physical, living, and social systems. CSSS brings together graduate students, ...

Cultural traits — the information, beliefs, behaviors, customs, and practices that shape the character of a population — are ...

We propose a theory of asset pricing based on heterogeneous agents who continually adapt their expectations to the market that these expectations aggregatively create. And we explore the implications ...

Applications for the third Complexity Global School (CGS) are now open. Like last year, the school will  be hosted at ...

Through meetings, schools, community events, and media, we invite curiosity-driven individuals to share our discoveries and support complex systems science. For more than 35 years, a small team of ...

This paper proves that one can not build a computer which can, for any physical system, take the specification of that system’s state as input and then correctly predict its future state before that ...

Climate change research often relies on downscaled general circulation models (GCM), projections of future scenarios that are used to build ecological and evolutionary models. With more than 35 ...

We are living in an age obsessed with intelligent systems. All walks of life are being transformed by machine learning, by software platforms that amplify human ability to manipulate mathematics and ...

The Santa Fe Institute is leading the world in complexity science, with a mixed group of physicists, biologists, economists, political scientists, computer experts, and mathematicians working together ...
