About the role Thanks to some new funding we are looking to hire several physics/math postdocs at the Wolfram Institute. The positions start this fall, 2025, and will initially be for 1 year. They can be virtual. What you'll do The focus will be topics related to the Wolfram Physics Project ( wolframphysics.org ). Current topics include: - Connections to other approaches (e.g. spin networks, string theory, etc.) - Infrageometry: Build a mathematical structure analogous to traditional geometry etc. but on top of limits of hypergraphs rather than Euclidean space. - General Relativistic Correspondence: Do explicit simulations of large-scale limits of hypergraph rewriting, understanding their correspondence and deviations from standard General Relativity. - Sub Quantum Field Theory: Explore the correspondence between multiway causal graphs and toy (and lower-level) versions of Feynman diagrams. - Experimental Implications: Search for situations (e.g. dimension fluctuations) where effects from our models are visible, and automatically mine existing literature for cases where such effects have been investigated. Qualifications We’re looking for outstanding people broadly knowledgeable about modern mathematical physics, with good fluency in Wolfram Language, who can thrive in intense intellectually rigorous projects, and who are able to deliver creative results within a defined overall framework. If you know people who might be interested, please email. People can also email me themselves or email opportunities@wolframinstitute.org (Send CV etc.) Feel free to share this post.
