Book Spotlight: Foundations of Relational Realism: A Topological Approach to Quantum Mechanics and the Philosophy of Nature by CPNS Research Fellows Michael Epperson and Elias Zafiris

In this unique two-part volume, Michael Epperson and Elias Zafiris chart out a novel, intuitive, event-ontological interpretation of quantum mechanics formalized via the mathematics of category theory and algebraic topology.


CPNS Announces New History and Philosophy of Science (HPS) Initiative for Fall 2014

Sacramento State's HPS Initiative includes new course offerings in the Department of History, a visiting speaker from NASA, graduate student liaisons at Stanford and San Francisco State, the Ultimate Questions Student Discussion Group, and more.

Book Spotlight: CPNS Senior Fellow Roland Omnès

Our work at CPNS is driven by recent advances in the understanding of physics that suggest a deeper philosophical relationship between mathematics and the natural sciences. This relationship is the subject of Converging Realities, the latest work by quantum theorist Roland Omnès, one of the leading thinkers on the subject. The book shows that the axioms needed for the mathematics used in physics can also generate practically every field of contemporary pure mathematics.

Ultimate Questions Discussion Group

The Ultimate Questions Discussion Group reads and discusses works of mutual interest in the philosophy and foundations of modern science and mathematics. All students—especially those in Natural Sciences and Mathematics and Philosophy—are welcome to attend, as well as all faculty from CSUS and area colleges and universities.


Michael Epperson - Director & Principal Investigator

The Center for Philosophy and the Natural Sciences at California State University Sacramento engages in research and scholarship that explores the philosophical implications underlying recent innovations in contemporary science, including those occurring in the areas of quantum physics, cosmology, and the study of complex adaptive systems. This exploration is, in part, a speculative philosophical enterprise intended to contribute to the framework of a suitable bridge by which scientific and philosophical concepts might not only be cross-joined, but mutually supported.
