The Physy project is a 1000+ page online reference work on higher mathematics and physics with the goal of developing an axiomatic framework for classical and quantum field theory, superstring theory, and supergravity, through the use of category theory and differential geometry.

Note. This project is a work in progress; some sections are incomplete and some references may be missing. Though the manner in which some ideas are formulated is original, this project should nevertheless be viewed more as a collation of ideas and results from existing literature into one coherent self-referencing document, and less as an original work. Comments, corrections, and missing reference suggestions are happily received at contact@physy-project.com.
