Quantum Gravity and Computation

Dean Rickles is Professor of History and Philosophy of Modern Physics at the University of Sydney, where he is also Co-Director of the University’s interdisciplinary Centre of Time. Recent books include Dual-Aspect Monism and the Deep Structure of Meaning (co-authored with Harald Atmanspacher; Routledge 2022); and Life is Short (2022).Xerxes D. Arsiwalla is a Mathematical Physics Fellow at the Wolfram Institute for Computational Foundations of Science, working on quantum foundations, pregeometry, higher category theory, formal language, and consciousness. He is an Academic Director of Physics Programs at Wolfram Research USA and a Co-Founder of the Association for Mathematical Consciousness Science (AMCS).Hatem Elshatlawy is an interdisciplinary researcher working at the intersection of theoretical physics, computation, and philosophy. Formerly a Research Consultant at Wolfram Research, he has contributed to developments in observer theory, multi-computation, and metamathematics. His interests include constructivist foundations of physics, physics of computation, and the computation of physics.
