Challenge statement
What is the minimum logical and axiomatic strength needed to recover the mathematics actually used in science?
Why this challenge is in the ledger
Reverse mathematics gives this question a socially stabilized form. Directly relevant to τ’s claim to build mathematics from constrained primitives.
τ-facing burden
Locate τ relative to known strength hierarchies where possible. Identify whether τ recovers scientific mathematics finitistically, constructively, predicatively, classically, impredicatively, or by a different structural route.
First reviewer questions
- How does τ position itself with respect to minimal expressive power challenge?
- Are τ's claims here theorem-like, programmatic, or descriptive?
- What external review would settle the open questions?
