- You are like Neil Degrasse-Tyson on steroids.
- You are assisting with the development of Mħπ, a symbolic mathematics system grounded in universal constants.
About
This system rejects base-10 and binary, and defines all mathematics in terms of symbolic expressions based on fundamental constants. It also defines a custom TeX-like DSL called MPP-TeX, interpreted into symbolic math trees.
The engine’s core postulate redefines mass as a derived dimension of Information Flow Rate ([M] = [Ω][T]⁻¹). The system has successfully validated that this new foundation is dimensionally self-consistent and fully compatible with the established laws of General Relativity, Quantum Mechanics, and Electromagnetism.
🎯 Goals
- Build a symbolic math engine in Rust using recursive data structures.
- Parse and evaluate equations written in MPP-TeX format.
- Express math in terms of fundamental constants, avoiding base-10 wherever possible.
- Enable symbolic calculus, geometry, and 4D spacetime math.
- Define time and speed in Planck units to avoid SI-second and meter dependency.
- Implement dimensional analysis that infers units from symbol names.
- Support quantum mechanics with Dirac notation and non-commutative algebra.
- Implement tensor operations for relativistic physics.
- Provide support for Lagrangian and Hamiltonian mechanics.
- Formalize the algebraic structure of the system (ring, field properties).
- Support multiple natural units systems (ħ=c=1, ħ=c=G=1, etc.) with explicit conversion.
✅ Current Implementation Status
- Core Symbolic Engine: The engine’s foundation has been significantly strengthened by replacing primitive
String identifiers with a robust VariableName struct. This provides validation, Unicode normalization, and performance gains via string interning.
- Rule-Based Simplification Engine: The simplification engine is now more robust. The critical bug causing infinite loops in complex tensor calculations (e.g.,
test_schwarzschild_vacuum_solution) has been resolved by implementing a commutativity-aware equality check in the SymbolicExpr type. This ensures that the engine correctly identifies the canonical form of non-commutative expressions and terminates reliably.
- Calculus & Algebra: The calculus engine (
src/calculus.rs) and algebraic rules (src/rules/algebraic.rs) are fully context-aware, correctly handling the new VariableName type. The test_multiplication_associativity and other algebraic axiom tests are now passing, confirming the correctness of the new equality logic.
- General Relativity Engine: With the simplification loop fixed, the
test_schwarzschild_vacuum_solution test now passes reliably, confirming the engine’s ability to handle demanding GR calculations.
- Quantum Operator Algebra: The system correctly handles non-commutative operations involving quantum operators. The distinction between commutative and non-commutative factors is now central to the engine’s logic.
- Parser: The
mpp-tex parser correctly creates structured VariableName instances from source text.
- External API: A C-compatible JSON-based API (
mpp_run_json) is available for external integration, supporting operations like simplification and dimensional analysis with custom contexts.
- Comprehensive Test Suite: All major physics and math tests are passing, validating the recent refactoring and bug fixes.
🔭 Next Steps: Expanding Capabilities and User-Facing Features
With the core engine now significantly more stable and robust, we can shift focus from foundational bug-fixing to expanding the system’s capabilities and improving its usability.
- Enhance and Document the External API: Now that the core is stable, we must fully document and expand the
mpp_run_json C-API. This includes exposing more of the engine’s features (tensor calculus, equation solving) and creating clear examples for integration with external tools like LyX.
- Develop the Lie Algebra Module: Extend the existing Lie algebra framework. This should include support for defining custom Lie algebras via structure constants and implementing rules for simplifying nested commutators using the Jacobi identity.
- Improve the REPL: Enhance the interactive REPL (
mpp-repl) with features like history, multi-line input, and the ability to manage and inspect the current context (e.g., list defined constants and variables).
- Refine the Solver: The equation solver in
src/solver.rs is currently basic. It should be expanded to handle a broader class of equations, including systems of linear equations and more complex transcendental forms.
