Abstract

FINDING: The core mathematical insight is the existence of *undecidable* problems — problems whose truth is independent of any fixed axiomatic system (Gödel/Turing) — and the Collatz Conjecture as a concrete, elementary example of a problem with no known proof or disproof, whose behavior is computationally irreducible. | MATH: Collatz map: \( T(n) = n/2 \) if \( n \) even; \( T(n) = 3n+1 \) if \( n \) odd. Conjecture: \( \forall n \in \mathbb{N}, \exists k: T^k(n) = 1 \). No closed-form solution; no known invariant. Turing's halting problem: \( H(P,i) \) — no computable function decides if program \( P \) halts on input \( i \). Hilbert's Entscheidungsproblem: no algorithm decides validity of first-order logic statements. | CONNECTION: The Collatz map is a discrete dynamical system on integers — its orbit structure is *not* periodic in any simple modular sense. However, the *statistical* behavior of the map (when considering \( \log_2 \) of the orbit) converges toward a ratio: the expe Author: Andrew Stewart Caldin, Independent Researcher, UK.
