A (somewhat) new paradigm for mathematics and physics | Diffusion Symmetry 1 | N J Wildberger
The current understanding of symmetry in mathematics and physics is through group theory. However in the last 120 years, a new strand of thought has gradually appeared in a number of disciplines, from as varied as character theory, strongly regular graphs, von Neumann algebras, Hecke algeb
