Framework Overview
Lean4PHYSICS introduces a comprehensive framework designed to advance AI's capabilities in formal physics reasoning. It comprises two main components: PhysLib, a foundational library for physics, and LeanPhysBench, a benchmark dataset.
The framework addresses the lack of foundational support for formal physics reasoning and provides a robust method for evaluating LLMs on college-level physics problems. By formalizing natural language problems into Lean4 theorems, it enables LLMs to learn domain-specific laws and reasoning patterns beyond general mathematical proving.
PhysLib Effectiveness
PhysLib is a community-driven repository that provides essential unit systems and theorems for formal physics reasoning in Lean4. Our experiments show a consistent 11.75% performance improvement for LLMs when PhysLib is integrated into the reasoning process.
This library allows models to handle unit consistency, algebraic operations for physical quantities, and offers a wider toolbox of advanced tactics like simp and norm_num, which are crucial for solving physics problems effectively.
LeanPhysBench Challenges
LeanPhysBench is the first-ever Lean4 benchmark for college-level physics, featuring 200 hand-crafted and peer-reviewed problems. Our evaluations reveal that all current expert math provers and general LLMs achieve suboptimal performance, with the best prover at 15% and the best general model at 39.5%.
The benchmark highlights significant challenges in transferring mathematical reasoning skills to physics, especially for problems involving complex symbolic manipulation, quantifiers, and calculus concepts within a physics context.

Impact of PhysLib on Proof Structure
Examining a college-level mechanics problem, Gemini-2.5-pro demonstrated different proof strategies. Without PhysLib, proofs were concise and relied on general Mathlib tactics for algebraic expressions. With PhysLib, the proof became more structured and systematic, utilizing Scalar.val_inj and PhysLib's unit system to handle physical quantities directly. This highlights PhysLib's role in providing a richer toolset for formal physics reasoning.
- — Without PhysLib: Relies on general Mathlib tactics, mechanical algebraic simplification.
- — With PhysLib: Structured proof, utilizes
Scalar.val_injfor real number conversion, better handling of physical quantities.
