In Generative Triangle T, combinatorial mass is defined only after a stable particle-like macroclass exists. It quantifies the multiplicity of stable microhistorical realizations compatible with that same macrostructure, rather than adding mass as an independent input.

A particle-like object in Generative Triangle T is not a primitive point. It is a macroclass satisfying recursive stability, causal localization, stable internal structure and asymptotic distinguishability. Particle-likeness is derived from those conditions, not postulated.

Sir Professor Roger Penrose is my favourite scientist.

This is a link to a post I did, which is a bit about him & part of a thread (of a few threads) I wrote about mathematicalphysics which references his books I have, & his thinking behind his theory making.

He's an expert on #mathematicalphysics
clairecsmith.bsky.social Claire C ζ(s)mith @clairecsmith.bsky.social · Jan 31
They're both physicists, altho Penrose is more mathematical in his thinking but they have similarities: both think in pictures & diagrams (Feynman diagrams) as does Penrose with his working out & theorising.

I reckon they'd get along as much as Feynman did with Dirac(2nd pic)!
