Topic: Derivation of the Fine Structure Constant from First Princip


MattScherf (Oct 29 2025 at 02:53):

Hi everyone,

I've completed a Lean 4 formalization that derives the fine structure constant (α⁻¹ = 137.036) and other fundamental physical constants from first principles. The complete formalization, with all proofs machine-checked, is available at github.com/matthew-scherf/137

Starting from 8 substrate axioms (uniqueness, indivisibility, timelessness, inseparability, gauge invariance, relational individuation, observational manifestation) plus 4 axioms connecting ontology to physics, the formalization derives:

  • Three fermion generations (∃! n_gen : ℕ, n_gen = 3)
  • Three color charges (∃! n_colors : ℕ, n_colors = 3)
  • Euler characteristic χ = -6
  • First Chern class c₁ = 3
  • Fine structure constant at GUT scale α⁻¹_GUT = 137
  • Phenomenological correction δ = 0.036 (computed from δ = N² × D × σ)
  • Observed value α⁻¹_obs = 137.036
  • Algebraic verification of the RG correction formula

The formalization uses a custom EnergyScale structure as a dependent pair bundling real values with certified positivity proofs. The renormalization group verification establishes that (β_eff / 2π) × ln(E_GUT/m_e) = δ through a series of auxiliary lemmas handling non-zero denominators and logarithm properties.

Key proof techniques include using dependent pairs for physical constraints (energy scales must be positive), existential elimination and introduction (obtain/use tactics), field arithmetic with certified non-zero conditions, numerical verification via norm_num and compositional theorem structure (each result builds on previous)

Instead of encoding physics equations directly, the formalization starts from ontological principles and derives physical structure as necessary consequences. All existence claims are constructive. The phenomenological correction is computed from first principles rather than fitted to data. The formalisation bridges metaphysics, topology, and quantum field theory in a single coherent framework.

I'm not an academic. No institutional affiliation, no physics PhD. I come from a contemplative background and have been working on formal verification of non-dual philosophical systems (Advaita Vedanta, Dzogchen, etc.) in Isabelle/HOL and Lean. This project emerged from exploring whether fundamental physical constants could be understood as emergent from ontological substrate properties.

Thanks for reading, and for creating such a powerful proof assistant and supportive community.

P.S. If this belongs in a different stream, please let me know and I'll move it. Wasn't sure if #new members, #mathlib, or #Lean 4 was most appropriate.

HI - I just published a derivation of the fine-structure constant from first principles https://github.com/matthew-scherf/137/

I don't quite understand what you are trying to achieve here, but the lean code looks a bit dubios. For example, there are multiple axioms which are just true:

axiom substrate_indivisible : True

axiom substrate_timeless : True

which does nothing. Also, these axioms just state tautologies:

axiom euler_characteristic_from_triplicity :  (n : ), n = 3   (χ : ), χ = -6

axiom chern_class_from_triplicity :  (n : ), n = 3   (c₁ : ), c₁ = 3

The first one says: For every n whch is three, there exists an $x in Z$ which is -6. This does nothing.
(Also, your final theorem ist just a simp call: livelean)

  1. This code looks very AI-generated. Did you use LLMs to generate this?
  2. If your are really trying to understand and learn Lean: Take small steps at frist before attempting to prove bigger things (with the help of LLMs). Not understanding what exactly you are proving is very dangerours, because lean can only protect you from "wrong" proofs, but not from nonsensical theorems or definitions.

Thanks for taking the time to look. All your criticisms are valid, and I've taken them onboard and made some changes. Could you please, pretty please, take one more look - imagine if I got this right.

I am currently on mobile (because i am sitting in a lecture), so no. This server is not a place to post ai generated content with the hope that someone verifies/fixes it. You are very welcome to learn Lean, please take a look at these ressources: https://leanprover-community.github.io/learn.html (i would recommend the natural number game, it is very double without academic background). If you have difficulties, feel free to ask (human) questions in the #new_members channel. But don't post ai slop.

MattScherf (Oct 29 2025 at 11:34):

OK. Thanks anyway, have a nice day.

Michael Rothgang (Oct 29 2025 at 11:47):

Also note that posting AI slop without further effort from you is against the community guidelines: https://leanprover-community.github.io/meet.html#community-guidelines. Please don't do so in the future.

Continuing to do so can lead to a temporary suspension or a ban. Hopefully this will not be necessary.
